Why do flies bite in August. An interesting question: do flies bite or not? Differences between a house fly, a stable fly and a gadfly

Flies appear with the first rays of spring. By August, they begin not only to interfere with their buzzing, but also to bite quite painfully. Why do flies bite, what is the reason for their aggressive behavior?

Many people think that flies simply, having a premonition of imminent death, become angry, which is why they bite. Such an opinion is erroneous.

Painful bites are caused only by certain types of flies - zhigalki, the number of which increases several times by autumn. These flies are trying to stock up on hibernation with the necessary amount of protein so that in the spring there is an opportunity to produce offspring.

They get protein from the blood of animals, people and even carrion. That is why zhigalki are distributors of anthrax, sepsis and other serious diseases.

When a fly bites through the skin, from its proboscis, or rather, from the glands, a poisonous substance penetrates under the skin, which causes a strong burning sensation.

It is because of the poisonous saliva that the flies got their name. It is difficult for a layman who does not have knowledge in the science of insects to distinguish an ordinary fly from a zhigalki.

It is worth noting that Zhigal flies are highly prolific: in a heap of manure, in animal wounds or rotten products, one female brings about 300-400 eggs. To prevent flies from curling in the house, it is necessary to simply keep order and keep food in the refrigerator.

Flies are dipteran insects that are common in the world. Scientists talk about the existence of almost 5 thousand species of these insects, among which there are biting ones. To provide themselves with vital energy, flies eat food that they find everywhere. This is the juice of plants, rotting fruits, organic matter, manure, feces. Sometimes they attack people and animals in search of food - readily available animal protein.

Penetrating into a person’s dwelling, the flies get bored, constantly buzz, sit on food and the body, and bite. This behavior forces a person to defend himself from annoying neighbors. The following types of pests are known, among which there are biting ones.

Gadfly. Evil, bite out part of the skin, bring dirt into the wound, lay eggs. often lead to local inflammation.

• Mosquito nets are used to prevent insects from entering the premises.
• In addition, insect traps are placed in opposite places of the room. For example, sticky tapes are popular.
• Chemical means of protection are used in places of reproduction of insects (dung heaps, livestock buildings).

Another way is to use insect predators that destroy domestic pests.

Video: Flies incredible harm - diseases and infections

When spring comes, and everything around begins to bloom, I want to go to the bosom of nature as soon as possible, eliminate the picnic. But these charms can be overshadowed by midges - winged insects, whose bites can cause irreparable harm to a person. Midges can be found on alleys, in parks and squares, they annoy urban and rural residents. Consider which flies bite, as well as why flies bite, and is there any reason to panic.

Mosquito bite danger

A person may not immediately feel the moment of a bite of a midge (in other words, they can be called midges), because the insect begins to inject an anesthetic that dilates blood vessels in the skin. But if the midge has bitten, then after a few hours a person may feel the first symptoms and ailments. They depend on the individual characteristics of the organism, as well as the degree of severity. The reasons for these factors are quite simple, because midges have a very poisonous saliva that causes characteristic signs.

Why does swelling occur

After the introduction of saliva, a biting fly can fly away and forget about its action, but after that a person has swelling after a midge bite. By the way, an allergy to midge bites is not the only manifestation. There are other risks associated with the possibility of blood contamination with viruses (the carriers of which are these insects), as well as with intoxication by microorganisms. The greatest activity of midges is observed during hot and sunny days, in August, most often they "attack" people wearing light-colored clothes. They often "hunt" at night. Also attracts them and the smell of sweat. In bad weather, such activity is not observed.

We remove the edema formed after the bite

It is not worth ignoring the fact that the midge has bitten, since the lack of treatment can cause vascular diseases. To prevent the negative effects of a midge bite, you can use various means, but the most effective measures are preferred.

Soda-based compresses made by mixing a teaspoon of soda in 0.5 cups of water.

Substances and preparations containing menthol, this also includes toothpastes with a cooling effect.

Ice, which is wrapped in a soft cloth, and applied for several hours, this will reduce swelling and inflammation.

But what to choose from bites if an allergic reaction occurs? After all, sometimes the midge bites painlessly. Consider how else you can treat the bites of representatives of this unwanted "neighborhood".

What needs to be done?

If the first itching from a midge bite appears, the affected skin area must be treated with pure alcohol or a special alcohol solution. This is necessary for disinfection and elimination of bleeding. After that, you need to ensure that the affected area is monitored for several days, to see what the midge bite looks like, what changes in symptoms occur over time.

The bite entails not only swelling, but also significant soreness. This is due to the special composition of the poison, you want to comb the affected area all the time. In this case, the treatment consists of regularly wiping the lesion with a 9% vinegar solution or baking soda. To disinfect the surface, brilliant green is used. Considering the answer to the question of how to treat the symptoms of a bite, it can be noted that even without any special manifestations, a preventive medication will be required. An effective drug is suprastin, which relieves redness and itching. If the place has swelled up, and the person has an allergic reaction, it is recommended to take fenistil. If all measures are taken, and the situation does not improve, the only thing to do is to consult a doctor.

Midge bite in the eye: measures and actions

All midges bite indiscriminately - what they see, the bite of a midge in the eye carries a special danger. When a midge has bitten into the eye, there are many manifestations - there is painful itching, increased release of lacrimal fluid, redness and swelling of the eye and mucous membrane, as well as around the eye area. If a bitten person suffers from an allergic reaction to such bites, additional symptoms if a fly bitten in the eye may include pain in the head, dizziness, shortness of breath and chest tightness. If the eye is swollen, being at the epicenter of the negative influence, measures must be taken.

In no case should you rub a bitten eye to ensure the safety of the mucous membrane.

Rinse and blot the wound, provide skin cooling with ice, apply a pressure bandage, blot the lesion with a swab or disc.

In traditional medicine, the situation is solved by applying an anti-inflammatory cream around the eye.

To remove toxins from the body, it is necessary to drink as much liquid as possible, preferably clean water.

If a child was bitten by a midge, or it happened to an adult, a series of actions must be performed. The most common complaint of affected people is the occurrence of itching, which leads to a strong desire to scratch the skin. To prevent a reaction to toxins, a number of actions must be taken.

Increased edema in children and adults can be cured with folk remedies.

If the eye is swollen, a slice of raw potatoes is applied to it;

applying crushed mint or bird cherry leaves will simplify the process;

special compresses made from parsley have an effect.

It is worth remembering that if the midge managed to bite the eye, and it is swollen, the first action to be taken is to seek specialized help in order to restore vision and eyes in a timely manner and return to a normal rhythm of life.

Bite in the leg: features

Midges can bite day and night, while absolutely any place can be negatively affected. The greatest danger is the case when the leg is bitten in the area of ​​​​the ankle or lower leg. The situation is aggravated by the fact that in this part of the body, swelling and other symptoms can persist for several weeks, which leads to the formation of circulatory disorders and the occurrence of vascular diseases. Therefore, if the area of ​​\u200b\u200bthe leg is swollen, appropriate measures must be taken.

Effective traditional medicine

Traditional medicine is far from the only effective remedy designed to deal with midge bites. If there are no allergic manifestations, all kinds of folk remedies are used for the treatment process, which can prevent an allergic symptom and eliminate swelling.

Plantain juice from a pre-mashed leaf;

soft mint leaves, preferably “young”;

gruel made from raw cabbage leaves;

onion head;

dandelion leaves;

essential oils of lemon.

To ensure prevention, especially at night, it is recommended not to use perfumes with pronounced aromas, and also not to wear too light-colored clothes. Mosquito nets must be attached to the windows.

Best Pharmaceuticals

Ointments with antiallergic effect

These funds are usually applied twice a day - day and night.

fenistil gel

cinovite in the form of a cream

ointment prednisolone

hyoxyson.

solcoseryl;

panthenol;

actovergin.

So, we looked at what the bites of midges look like in the photo, and determined exactly how different midges bite. If any part of the body has been negatively affected and has had time to swell, it is important to take certain measures in a timely manner.

Diptera are activated in autumn - during this period they begin to bite animals and people. Females are especially aggressive, because they need improved nutrition in order to produce offspring. The danger of a fly bite is that when an insect punctures the skin, it can infect a person with an infection. Among these insects, which are ubiquitous, there are extremely dangerous individuals. For example, the tsetse fly. It is considered the causative agent of trypanosomiasis. Fortunately, such species live only in Africa, but travel enthusiasts should remember that the bite of a fly of this kind can be fatal.

There are surprisingly many varieties of Diptera. There are 120,000 species of these insects. A fly has as many wings as all dipterans, that is, a pair. They are found in different parts of the globe, but the most dangerous species love a warm climate. If we talk about the types of flies in Russia, then these are:

At one time, millions of people suffered from the plague bacillus carried by Diptera. But even now the Diptera should not be underestimated. So, the African fly is a carrier of sleeping sickness. What is dangerous about this disease is irreversible neurological disorders.

Tsetse flies, the carriers of the disease, live predominantly in tropical and subtropical Africa, and the habitat of tsetse does not change. It is possible to bring a dangerous insect from the continent, but it will not breed in unusual conditions. The features of tsetse or Glossina are considered to be a long proboscis, wings superimposed on each other and an expressive pattern.

Why do flies sometimes bite

It is noted that the flies are meaner in August. During this period, their number reaches a maximum. Females plan to lay eggs and need additional food. It is this fact that explains why the flies bite intensely in August. Note that not all flies bite even in autumn, and we have already found out which species attack humans. These are mainly zhigalka, horsefly and bloodsuckers.

ICD code 10

In the case of a bite from an infected Diptera, code the disease according to the resulting disease. If a tsetse bite occurs and the person is diagnosed with sleeping sickness, code B56 is assigned.

Bite symptoms

You need to know what a bite looks like so as not to confuse it with, because flies bite actively just during the honey collection period. Among the characteristic manifestations:

• redness;
• itching and irritation;
• slight swelling;
• local rise in temperature.

What do baby bites look like?? Usually the symptoms are more pronounced. Spots and bite marks increase in size and become intensely red. When bitten by a tsetse fly, boils develop.

First aid

The most painful are multiple injuries: if a fly has bitten a fly on the legs, arms, stomach and other parts of the body, inflammation develops. Soft tissues swell from the bite, general well-being may worsen. The bite wounds are treated with an antiseptic - brilliant green, alcohol, iodine.

How to smear bites in babies? In this case, non-alcoholic agents will help - chlorhexidine, hydrogen peroxide. Also, when bitten, soothing and cooling ointments help out, which makes the manifestations of local reactions less. So that fly bites in children do not provoke allergies, they give "Zodak" in drops or "Diazolin for children."

Treatment

At home, bites can be treated only if the possibility of infection is excluded. From the bites of ordinary flies, allergic reactions and hyperemia develop. How to treat the victim in this case? If, after a bite, a limb is swollen - a leg or an arm, it is recommended to carry out an antiseptic treatment and cool the injury site. Treatment involves taking antihistamines. Gel can be applied to the treated area - "Nezulin", "Fenistil". How to treat insect bites in children, the pediatrician will tell you, usually you can get rid of the consequences with the help of Bepanten, Rescuer.

Complications and consequences

If the flies bite in the fall, then their attacks do not cause much concern. As it gets colder, the insects will disappear. However, multiple bites provoke allergic reactions and skin diseases. Another thing is the consequences of the bite of such a fly as tsetse. Complications can develop several weeks or months after the pathogen enters the human body.

The specificity of this disease is a long period of development - up to 5 years. After infection with trypanosomes, the first period begins - hematolymphatic. Blood poisoning in a tsetse victim is accompanied by fever. An insect bites only once, and this is not enough to cause irreversible changes.

Ataxic gait, tremor of the limbs speak of a mortal danger to a person, there are signs of depressive states. Then a coma develops.

Prevention

The incidence of sleeping sickness has decreased significantly in recent years, which is associated with increased prevention. They try to avoid tsetse habitats and dangerous areas - tropical shrubs, agricultural areas.

If flies are disturbing in the house, insect repellers are used, and they act on individuals of various species. Among the methods of combating tsetse is the treatment of clothing with permethrin. You can drive out insects that traditionally settle in the house in more affordable ways. A reliable remedy for flies is vinegar traps. Wine is used instead of vinegar.

If the biting fly ignores sticky tape and light traps, essential oils will help out. The aromas of cloves, basil, lavender will be able to drive the fly out of the room. And a reliable way to get rid of flies in the apartment is regular cleaning. If the room is clean, the floors are washed, the drains are cleared, there is no food leftovers, then the insects will be uncomfortable in the house.

Flies appear with the first rays of spring. By August, they begin not only to interfere with their buzzing, but also to bite quite painfully. Why do flies bite, what is the reason for their aggressive behavior?

Many people think that flies simply, having a premonition of imminent death, become angry, which is why they bite. Such an opinion is erroneous.

Painful bites are caused only by certain types of flies - zhigalki, the number of which increases several times by autumn. These flies are trying to stock up on hibernation with the necessary amount of protein so that in the spring there is an opportunity to produce offspring.

They get protein from the blood of animals, people and even carrion. That is why zhigalki are distributors of anthrax, sepsis and other serious diseases.

When a fly bites through the skin, from its proboscis, or rather, from the glands, a poisonous substance penetrates under the skin, which causes a strong burning sensation.

It is because of the poisonous saliva that the flies got their name. It is difficult for a layman who does not have knowledge in the science of insects to distinguish an ordinary fly from a zhigalki.

It is worth noting that Zhigal flies are highly prolific: in a heap of manure, in animal wounds or rotten products, one female brings about 300-400 eggs. To prevent flies from curling in the house, it is necessary to simply keep order and keep food in the refrigerator.

The closer autumn, the more painfully the flies bite. Sometimes it seems that these are not tiny insects, but a real tiger has bitten your leg. Especially when you notice a quirky bully too late and give him time to prepare a full-fledged “strike”. But why do flies bite? Is it really so pleasant for them to torture innocent people? Or is there another, more significant reason?

Biting flies - who are they?

The truth is that not all types of flies are capable of harming humans. Moreover, the vast majority of these insects are completely harmless, except for the fact that they spoil food by laying their eggs in it. Otherwise, they only buzz overhead, thereby acting on the nerves.

Biting flies are a completely different matter. These creatures, although similar in appearance to their fellows, are still very different from them in their habits. In particular, those that like to consume the blood of other creatures. Therefore, it would be quite logical to talk about which flies bite the most and how to distinguish them from peaceful insects.

Annoying Stinger Fly

A more familiar name for this species is the autumn zhigalka. A similar name is due to the fact that this insect moves into people's homes only with the arrival of autumn cold. The reason for this behavior is quite simple: as soon as the temperature drops below 8 degrees, the fly will die. Therefore, she climbs into warm rooms in order to save herself from the coolness of the night.

Outwardly, the Stinger fly is very similar to its harmless relatives, only slightly larger than them. So, an adult has a body length of 5-7 mm. At the same time, the fly itself is gray: there are several dark spots on its belly, and four horizontal stripes of the same color go along the chest.

She bites because she needs blood. For her, this is an excellent source of energy, moreover, easily accessible. A razor-sharp proboscis helps her to pierce the flesh, which easily cuts both human and animal epidermis.

Moreover, these biting flies inject a special enzyme into the wounds of their victims, which stops blood clotting. It is he who causes a strong burning sensation, which increases as the toxin spreads through the blood. In addition, such a solution can cause an allergic reaction, which is fraught with high fever and an attack of nausea.

Inhabitants of the coastal regions

Horsefly is one of the species of flies that live mainly near water bodies and clusters of cattle. Such a sonorous name of the species came from the fact that during a bite the insect becomes defenseless, as if an invisible veil covers its eyes.

To begin with, these biting flies are very similar to mosquitoes. That is, only females drink blood, since it is needed to conceive offspring. As for the males, they are vegetarians and feed on plant nectar. Therefore, you need to be afraid only of "girls", who also have a very stubborn character.

The appearance of horsefly largely depends on its subspecies. So, the length of his body can vary from a few millimeters to two centimeters. For example, bullfly grows up to 2.5 cm, which is why its bites are extremely painful. As for the color, this species is easily recognizable by the red-yellow horizontal stripes that encircle the abdomen of the insect.

The danger posed by gadflies

The gadfly is another type of flies dangerous to humans. These insects live mainly near the pastures of animals, since they are their main goal. Unlike their biting relatives, they do not feed on the blood of other creatures. Moreover, scientists have recently discovered that adults do not need food at all. They are quite satisfied with the reserves that they have acquired while at the larval stage.

However, a completely justified question arises: why do they then bite animals? The fact is that during the bite, they lay their eggs under the skin of the victim, thereby providing them with an excellent source of food. Let's be frank that after the appearance of larvae from eggs, the poor animal experiences terrible pain, as they literally eat his body from the inside.

But the main danger is that gadflies can lay their eggs on human skin. Let this happen rarely, but the consequences of this accident are extremely sad. After all, the only reliable way to get rid of the larvae is the partial removal of the infected area of ​​\u200b\u200bflesh.

tsetse fly

The most dangerous of all biting flies, tsetse, lives in Central Africa. Science knows that this insect is a carrier that affects about 10 thousand people a year. It should be noted that most of those infected die, since this disease is practically untreatable, especially in the later stages.

At the same time, she calmly tolerates the effect of the pathogen. As for the reasons, this insect feeds on blood. At the same time, it does not matter to him at all whether she is human or animal, the main thing is that she should be enough. Fortunately, modern medicine every year is getting closer and closer to creating a vaccine that can permanently protect the human immune system from this deadly virus.

Everyone knows the pesky houseflies. And in August they also start to bite. Well, they really “go wild” before the cold. In fact, this is pure delusion, because bite us not the usual flies we've seen all summer, but flies. It’s just that their numbers increase towards the end of summer, that is, in August.
fly bite at the same time it is very painful because of the poison that it injects. It is desirable to treat the bite site - a solution of soda, a drop of celandine or other means. But that's not all, fly-stinger can carry a number of infections found on animals: intestinal, sepsis, trypanosomes, anthrax, etc.
Outwardly, the blood-sucking stinger fly is very similar to the common housefly. But if you look closely, then her proboscis will be pulled forward. In the summer, when it is warm, these flies are near the accumulations of animals. They can be found on farms, pastures. The blood of animals is their main food. Moreover, both females and males are blood-sucking. In such conditions, the number of flies grows.
And with the onset of cold nights, they rush to warm rooms. There they find people and, in the absence of anything better, try to bite them. That's the whole secret of biting flies!
We are people - trying to get rid of any(predatory and non-predatory) flies. That's why we close the windows mosquito nets keeping these insects out of the room.
We hang in the house sticky tapes and change them as needed.
We run after them with a newspaper or fly swatter until the last one stops buzzing.
Cooking traps and other means of struggle themselves. For example, you can cut off the top of a plastic bottle. Pour the sweet solution into the rest of the bottle, and insert the cut off part on top with a narrow neck down. Get a trap. Or cook poison based on black hot pepper. Take 150 ml of milk, add 10 grams of sugar and 10 grams of black pepper. Let's mix. Then we take a sheet of thick paper, soak it with the resulting solution and put it on a plate. As it dries, you need to drip water on it.
Why fight them at all? Then, that house flies live and breed in food waste. Therefore, they carry infections such as helminthic infestations, intestinal infections, tuberculosis, etc. Their presence on foods can cause food poisoning.
Ordinary house flies are a kind of indicators of decay. Accumulations of them may indicate that food residues are decomposing nearby. Let's be vigilant! We will clean up the food and keep it clean! The persistent smell of food attracts flies from 2 km away. Therefore, food must be removed from the table.
In order to realize favor flies It should be noted that there are about 5 thousand of them in nature, and each of them helps us through the chains of biogeocesis. Flies maintain the species diversity of plants, pollinating their flowers. By the way, there are species whose existence depends only on pollinating flies. Let's also recall the unique pollinators -.
Flies help to process plant and animal waste, excretions of animals and humans. turning them into valuable fertilizer.
They are are nutrition for frogs, birds that owe their lives to flies.
flies are our trainers , because chasing them, we train dexterity, reaction time and accuracy.
And there is also an opinion that flies also contain natural substances that are capable of destroying infections carried by them. In this regard, the flies themselves do not become infected. “If a fly gets into the vessel of one of you, then immerse it completely, truly, on one wing it has a disease, on the other - healing” - the prophet Muhammad.
Therefore, we will stretch mosquito nets, put bouquets of carnations and tansy on the window and enjoy the flow of life around us!

In addition to true bloodsuckers - mosquitoes and bedbugs, there are some types of flies that gladly replenish this category of insects. The question here is not whether flies actually bite or not, but which flies bite and why in August or autumn. Oddly enough, it is not the usual house flies that attack a person, the oral apparatus of which is not adapted for bites. The main predators living on the territory of Russia and carrying out an attack on humans are:

Autumn flies

Stomoxys calcitrans. Outwardly, biting flies are very similar to habitual flying insects. And after their painful attacks, bewilderment arises - do house flies bite. There are differences in appearance, but they can only be noticed after careful consideration, these are:

Habitats and life cycle of the zhigalka

The usual habitat of the insect is pasture for livestock, a barn or paddock. Under these conditions, both a table and a house are always ready for them, that is, an abundance of warm-blooded animals as food and overripe hay or manure for reproduction and rest. The diet of the insect is only blood, and in one bite, the flies drink a volume twice their own weight.

The breeding characteristics of bloodsuckers give the answer to why flies bite at the end of summer. Masonry, zhigalki arrange in manure or in animal litter, in the warmest places at a temperature not lower than 35 ° C. The insect goes through a full cycle of development, but the time of each stage is much shorter than that of the house fly.

The laid eggs develop only a day and release the larva, which, in turn, successively passing through four stages of maturation, after 4 days turns into an adult insect. And in a day, the insect in the adult stage is ready for mating. The life cycle of a fly can be 7-8 weeks, and during this time, the Stinger makes 5-7 clutches of 100 eggs. When it gets colder to 10°C or lower, the burner goes into hibernation. It can overwinter at any stage - larvae, eggs and adults.

Why do flies bite in autumn?

The onset of a cold snap makes zhigalok look for warmer places and during this period they may appear in the house. How flies bite is remembered for a long time. Unlike an ordinary flying insect, chitinous plates are located at the end of the proboscis at the end of the proboscis. With them, she scrapes the skin to the blood vessel and, before eating, injects a poison that prevents blood clotting.

Both females and males attack. By the end of the summer period, the insect population is quite significant and the person who falls under their arm begins to wonder whether house flies bite or some others. The bite of this insect causes burning pain, followed by swelling. In addition to painful sensations, the burner carries many pathogens of dangerous diseases:

• sepsis;
• tularemia;
• trypanosomiasis;
• anthrax, etc.

For parents, if their children were attacked by a stinger, it is necessary to urgently consult a doctor, and not to think about whether the flies bite in August in a city apartment.

Other flies that bite

A visit to a forested area can bring acquaintance with other types of dipterous predators, especially if there are water bodies nearby.

horseflies

Tabanidae. The attack is carried out by female insects, since they need blood for a successful pregnancy. The oral apparatus of horseflies is universal and is equipped with both mandibles for eating plant food and chitinous stylets for piercing the skin and feeding on blood.

The interesting question here is not what flies bite during pregnancy, but how much blood they consume at a time. The female horsefly is very bloodthirsty and can consume up to 200 mg of blood per intake.

Blood-sucking midge

Bysson maculata and Odagmia ornate. When flies bite, it is painful, but when a swarm of midges attacks, it is also fraught with severe swelling and allergic reactions. Moshkara, these are the most biting flies in August and June. With a large number of midge bites, the development of simulidotoxicosis is possible.

The short proboscis does not contribute to rapid penetration to the blood vessels, so the midge carefully chooses the bite site in order to quickly get to the blood. Most often it is the eyelids, nose, open limbs.

Like horseflies, the female feeds on blood for procreation. Blood proteins are needed for the formation of the egg shell and as a supply of nutrients. Since eggs are laid in water bodies, it is there that the greatest number of them is observed.

This insect is called a cattle tormentor. Many do not know whether these flies bite people or not. The peculiarity of the life cycle of an insect lies in its long existence in the form of a larva, inside a living carrier.

In the imago stage, the gadfly exists only for a few days. During this time, he needs to find a warm-blooded carrier - a forest animal or livestock. In extreme cases, the laying is made in the grass and can get into the stomach of the herbivore. There are cases of attacks on humans. With such attacks, in case of development of edema, it is necessary to urgently consult a doctor.

To protect against blood-sucking insects, especially in forests, it is recommended to wear discreet tight clothing and use repellents. In the house, use Velcro, repellent essential oils and protective nets.

With the onset of the first warm spring days, insects appear, including the ubiquitous flies. And if during the spring and most of the summer they behave mostly peacefully, then in August the flies bite, and very painfully. It was believed that they become evil in anticipation of death with the onset of the cold season. This is fundamentally wrong - in the fall, another type of insect attacks people and bites painfully - the flies, the number of which increases many times by the end of summer.

Stinger flies are very similar in appearance to ordinary house flies, differing only in the structure of the proboscis

Flies are two-winged insects distributed throughout the world. Currently, about 5 thousand of their species are known. The bulk feeds on plant sap, decaying fruits and other organic matter, feces, and manure. Only a small part of these insects bite. Blood-sucking flies are capable of attacking people and animals. The most common of these are stinger flies.

In appearance and biological features, zhigals are very similar to house flies, which is why they believe that house flies bite. These are gray insects 5-7 mm long. The main difference from non-predatory species of flies is in the structure of the proboscis. Ordinary flies cannot bite a person or animal, since their proboscis is soft and cannot pierce the skin. Zhigalok's proboscis is elongated and "armed" with rough chitinous plates, with which they cut through the skin of the victim. Both females and males of these insects feed on blood (and therefore bite). Mostly their victims are animals and only occasionally - people. Penetrating under the skin with their proboscis, zhigal flies inject poisonous saliva into the wound, so their bite causes severe pain and itching.

During the summer, Zhigals are found in large numbers in places where domestic animals gather - on pastures and farms, where they have all the conditions for feeding and breeding. During her life, one female lays up to 400 off-white eggs in manure or decaying plant debris, and sometimes in animal wounds. The larvae hatch from the eggs in 1-5 days, depending on the ambient temperature. In the larval phase, the future fly stays for 2-4 weeks, after which a pupa is formed. After another 7-26 days, young stallions are born, which are able to lay eggs for about 10-15 days. Thus, the cycle of development of a fly from an egg to an insect release lasts from three to eight weeks. During the warm season, several generations of Zhigalka manage to emerge, quickly increasing their numbers. By autumn, the largest number of individuals is reached.

The mechanical method of dealing with flies is the simplest and most harmless, but ineffective

In autumn, with the onset of night cooling, these insects often fly into houses and apartments for warmth, and, having no other sources of food, bite people. That is why most often these insects bite in the fall. The appearance of a stinger fly in human habitation is especially dangerous if there are infants or the elderly and disabled in the house who are not able to drive away insects and prevent a bite.

Stinger flies feed on blood, which means they bite animals and people. At the same time, they are able to carry pathogens of dangerous diseases, such as tularemia, sepsis, trypanosomiasis, anthrax, and many others. It is clear that it is better not to allow the bites of these insects. Control measures for biting flies are practically the same as methods for dealing with house flies. They can be divided into mechanical, chemical and biological.

• Mechanical barriers include various barriers on windows and ventilation in the form of mosquito nets that prevent insects from entering the premises.

To destroy those individuals who managed to get into the apartment, sticky tapes or various types of traps are used.

These methods are effective in controlling adult flies and are aimed at preventing insect bites. These methods are harmless to residents, which is why they are used mainly in residential areas.

• Chemicals, which include various insecticides, help get rid of not only adult insects, but also larvae. Farm premises, manure heaps, animal stalls are treated with these preparations.
• In large farms, it is possible to use biological control methods that are completely harmless to humans and animals. For this purpose, predatory insects (entomophages) are used, which feed on various types of flies and their larvae. The population of harmful flies will decline rapidly.

Probably, many notice that annoying flocks of flies fly every summer. Especially annoying are those that penetrate human habitation. They buzz, sit on the body and food. And the flies bite! Or not? And this is what needs to be dealt with.

Do flies bite or not?

It is impossible to answer this question unambiguously. Some flies, such as gadflies and autumn stingers, are able to sting a person, and it is very painful. The bite site not only itches, but sometimes it becomes so inflamed that the temperature rises, especially if there were many bloodsucking insects that decided to feast on human blood. So, asking the question of whether the flies bite or not, you should answer: “It depends on which ones.”

Still exist These insects live in Central Africa. With their bites, they spread sleeping sickness, which sometimes ends in death.

common house fly

Everyone knows how they get bored when they get into a human dwelling. But about whether these flies bite or not, not everyone knows. Most people are inclined to believe that these insects are quite friendly in June-July. But in August they turn into real monsters! But that's not the case at all.

Houseflies are two-winged insects and belong to the family of true flies. In the wild, they are almost never found. Houseflies are predominantly diurnal.

Flies have four wings, but they use only the front wings for flight, and the rear ones are reduced, they are needed to maintain balance.

Flies can only eat liquid food. To eat solid, they need to dissolve it in their saliva. In order for the female to lay eggs, she needs protein food. Their life expectancy depends on the temperature of the environment in which they are located. Optimal for flies are 25 degrees.

But these insects cannot bite living beings. Therefore, the main harm from them is that houseflies carry various infections on their paws. After all, in the summer they live not only in houses, but also in latrines, near garbage dumps, finding food for themselves there.

fly gray

These Diptera can be up to 25 millimeters long. But these are very rare, ten-millimeter gray flies are more common. They are gray with black spots and red eyes. Often they are confused with ordinary flies. But this insect is much larger.

In addition, these Diptera lay larvae immediately. The place of masonry is rotten fruit, carrion, feces, manure - any organic matter. For this, gray flies are called meat flies. No one would have thought that the meat gray fly is even somewhat useful. These winged carriers of infection act as natural orderlies, destroying carrion.

autumn zhigalka

Many notice that by the end of summer the flies seem to become more vicious. Now they are not only annoying with their buzzing and crawling over the body and products - they sting painfully. And many are interested in why flies bite in August.

People used to say: flies take revenge on people for seeing the next spring, and insects will die. But all this, of course, is a myth. It came from simple ignorance. After all, people blame the bites of ordinary houseflies, believing that for some reason they suddenly changed their food habits.

But in fact, they incorrectly answer the question of why the flies bite in August. Just during this period, the life cycle of a special type of flies, which are called zhigalki, begins.

These Diptera are extremely prolific. They leave their eggs everywhere, laying them many times a season. Therefore, in August, a myriad of them fly. These insects bite painfully because they feed exclusively on blood, piercing the top layer of the skin with their sharp proboscis.

These bites are not only painful. Stinger flies are carriers of dangerous viruses and infections. Therefore, you should, if possible, protect yourself and children from them: put protective nets on the windows, use repellents while walking.

Do flies bite - most people will answer in the affirmative. But not everyone suspects that only certain species do this. Insects are especially active at the end of summer, in autumn. People explain this phenomenon by the imminent death of insects. This statement is incorrect, the reason is completely different.

biting flies

There are about 5 thousand in the world. They differ in color, size, feature of life. Most of them feed on the juices of plants, decaying fruits, corpses, manure, feces. Their oral apparatus is equipped with a special proboscis for sucking food, but it is so soft that it is not able to pierce the skin of a person or animal. Such insects do not bite people, do not attack pets, wild animals.

A biting fly is a stinger. Distributed everywhere. It differs from the usual arrangement of the wings, which are directed to the side, not along the body. As well as the oral apparatus. At the end of the proboscis there are special bristles that can bite through the epidermis. Why flies bite - to replenish vital energy reserves, to be able to lay eggs.

Interesting!

Whether or not flies bite, one can argue endlessly. And all because a person does not see the difference between an ordinary annoying insect and a stinger, which are active at the end of summer. They spend most of their lives in the wild, attacking animals, but with the onset of cold weather, they look for favorable places. They enter a person's house through open windows, doors, cracks, bite in August, in the fall before the onset of persistent cold weather.

Varieties of biting flies

They bite in autumn, at the end of summer. Both males and females need to replenish their blood reserves. The development cycle of a young Zhigalka lasts about a month. Initially, females lay eggs in rotting plant food, from which larvae appear - white worms. After 3 weeks of their existence, they pupate, adult insects appear. Already on the tenth day, females can lay eggs.

What flies bite extremely actively - horseflies. Large representative of the genus.

On a note!

The most bloodthirsty females - at one time they can drink as much blood as 70 mosquitoes can do at the same time.

A biting fly lives near water bodies, it determines the victim by its natural smell - carbon dioxide when exhaled, sweat. reaches a size of 3 cm. Horseflies are distributors of dangerous diseases - anthrax, poliomyelitis. Even in the absence of infection, their bites are extremely painful, causing instant redness, swelling, and intense itching.

The most dangerous species is found in Central Africa. The insect carries a deadly sleeping sickness, infects through a bite. A few minutes after the attack of the pest, there is a deterioration in well-being, the temperature rises, the lymph nodes increase, and serious signs of intoxication appear. The last stage of the disease is not treated, which leads to death.

What insects should not be afraid of:

• Gardeners often encounter an earth fly -,. These are bright pests of garden crops, with which a merciless struggle is being waged, but they do not bite a person.
• , carrion or colored fly has an extremely beautiful body color. Plays of green, yellow, emerald. Can be annoying, but not capable of inflicting a bite.
• Insect, and fly -. The body is yellow with black stripes, long transparent wings. An absolutely harmless creature, despite the outward resemblance to a wasp.

On a note!

For a person in the house, it is the stinger that poses a danger, which at the end of August makes its way into the dwelling by all means, displacing ordinary houseflies.

Signs of bites

The insect is active during daylight hours. It bites on open areas of the body. It can bite legs, arms, back, stomach, neck, shoulders. The bite of a fly is especially pronounced in children. The insect injects a special substance that prevents blood clotting, facilitates the process of nutrition. The body instantly reacts to the ingress of pest saliva, damage to the integrity of the skin.

Bite symptoms:

• sharp pain;
• redness;
• edema;
• dot with gore in the center;
• swelling;

A photo of a fly bite is located below. In children and people with sensitive skin, allergies are much more pronounced. A large red spot appears, the limb swells, the itching does not stop.

In most cases, the symptoms disappear on their own without special treatment in a few days. If the bite itches, treat the sore spot with ammonia, medical, any alcohol tincture - calendula, valerian, motherwort, ginseng. Wash the wound with water and laundry soap, apply a paste of baking soda to the bite site.

If the leg is very swollen after a fly bite or other serious allergy symptoms appear, antihistamines are taken, external antiallergic agents are used.

Mosquito nets are placed on windows and doors to prevent pests from entering the house. They hang it in the room. Aerosols are used for harassment - Dichlorvos, Karbofos, Reid, Clean House.

Probably, many of us have noticed that with the onset of autumn, some insects, especially flies, begin to show a little more aggression towards humans than usual.

Why do flies bite in general? Are there blood-sucking flies? These questions are answered in this article. As well as the explanation of what makes the bloodsucking flies show such an unhealthy interest in a person precisely in the autumn period, which only intensifies with the onset of the first cold weather.

Who bites?

Let's not hide the fact that among such insects, seemingly harmless in terms of physical impact on the surrounding insects, like flies, there are many predators. We will not dwell on exotic varieties like the tsetse fly or the Siberian gnat, but let's talk about our native, domestic, one might say, kind of biting flies, which isautumn burner.

Zhigalka autumn: description.

Autumn Stinger is an insect from the family of real flies. Outwardly, the autumn fly practically does not differ from any other, the same room fly. It is also small in size, usually reaches a length of no more than 5-8 mm. It has a solid gray color with a slightly darker thoracic region and a slightly lighter abdomen, on which black dots can be seen.

The main distinguishing feature of these insects is their predatory nature. These are the same bloodsuckers as mosquitoes or vampire bats. Their mouth apparatus has a proboscis-like structure that allows these bloodsuckers to pierce the skin of warm-blooded animals and suck out the blood that serves as food for these predators.

How does the bite happen?

The fly, as we have already said, has the necessary tool to access our blood. Her proboscis has a pointed shape, and even along the edges of its tip there are small teeth resembling a nail file. At the same time, the tip of the proboscis looks flat, resembling a serrated knife.

With the help of these teeth, the insect wipes the top layer of the skin, after which it injects its poisonous saliva into the bite site, the composition of which does not allow the blood to clot quickly. Thus, having drilled a hole in the skin, this bloodsucker licks the blood droplets that have come out.

What is dangerous?

Development phases of flies.

Well, here we even start with the fact that the bite of a zhigalka is very painful. After all, it is not without reason that this species of flies received such a name. At the time of the bite, a person feels a rather strong burning pain.

This is not at all a harmless mosquito bite that appears only some time later, no. Zhigalka acts, shall we say, much rougher. A mosquito next to a fly is just a jeweler in his business.

In addition to, in fact, a painful puncture with a proboscis, a fly-stinger, moreover, brings saliva that irritates the affected area, which has an inflammatory effect at the site of the bite.

In addition to pain and inflammation at the puncture site, these two-winged pests, like all flies, are malicious carriers of all kinds of dangerous diseases.

One can only imagine how many times this pest used its stabbing weapon during the season, and how dangerous the bite of such a carrier of any nasty things can be for a person.

Among those diseases that the bite of such a bloodsucker can reward us with, we highlight the following, namely:

• typhus;
• sepsis;
• anthrax;
• tuberculosis;
• dysentery;
• polio;
• trypanosomiasis.

And this is not the whole list of “free services” that this pest can voluntarily and completely free of charge provide to us.

How to treat a bite?

Now it is quite reasonable to talk about what to do if a fly has bitten. First aid measures are somewhat similar to those that turn out to be with a wasp sting, however, of course, in a much more relaxed version.

So, if you were bitten by a fly, you need to do the following:

• wash the wound, preferably with hydrogen peroxide or just soapy water;
• take an antihistamine, for example, suprastin;
• to relieve pain, you can apply cold lotions with ice to the bitten place;
• treat the bite site with iodine;
• monitor your condition and the appearance of the wound for suspicion of infection.

Thus, if everything goes well and the bite site begins to heal (usually the next day), you can not worry, the inflammation will soon go away on its own. If there is a persistence of the inflammatory process at the site of the bite, or, even more so, on the face of a deterioration in well-being, you should immediately consult a doctor.

Why do they bite?

Here we come to the main issue of this review. Indeed, why do flies tend to bite, especially somewhere from the end of August, until the November frosts.

In part, we have already answered the question earlier, pointing out the predatory lifestyle of these insects and their need for blood for nutrition. But this is only one side of the coin, because the blood is also necessary for the stingers to be able to produce offspring, like mosquitoes.

This biting fly becomes active in autumn for the simple reason that the insect feels the approach of cold weather. The fly quickly reacts to the tendency of the daily weather to steadily strive to worsen the conditions for the life and reproduction of the insect, hence the behavior of these biting bloodsuckers shows nervousness and haste.

Among the reasons why flies still bite in autumn, we also note the maximum increase in the population of insects of all species from August to October. That is, competition in the struggle for food sources is increasing.

Also, one should not forget about the cold weather, the approach of which makes insects increasingly intersect with humans, stimulates them to look for suitable places for wintering or laying eggs in human habitats.

Prevention

Here it is very short and without innovations. At home, do not forget to use mosquito nets on the windows. And on the street, and especially during suburban country maneuvers, you should use special sprays that repel bloodsuckers and do not yawn.

Conclusion

So, we found out the main reasons why the flies were biting last fall. Now we know that not all flies are harmless, and among them there are many that can deliver memorable sensations with a painful bite.

We also got acquainted with such a variety of flies as the Stinger, and now we know that this bloodsucker is a carrier of many dangerous diseases, with which this insect can reward any gaping lover of outdoor recreation.

Flies wake up in the spring, accompany us in the summer and even in the fall do not give rest. But if at first they pester only with their buzzing, then since August they have already been biting. Popular opinion says that insects become evil with the approach of autumn, as they will die soon. However, this version, of course, does not have any confirmation, if only because insects cannot experience any feelings. So why do flies really bite?

With their bites, flies annoy not only humans, but also animals.

Who bites us and why

Those flies that have been with us throughout the spring and summer are not capable of causing any harm. These are ordinary houseflies with a soft proboscis, which is simply not designed to pierce hard skin. Such insects feed exclusively on plant juices, fruits, waste products and plant debris, and in general, are harmless.

And closer to cool days, representatives of another species become especially active - zhigalki. It is these flies that bite in August. Outwardly, the stinger and the housefly are very similar, so they are constantly confused.

Habitats of zhigalok

Predatory flies live mainly on farms and pastures, where they bite cows, bulls and horses, since it is their blood that forms the basis of the diet. Farmers do their best to get rid of the pest, however, due to the high breeding rate, swarms of carnivorous flies do not decrease.

On a note! The Stinger fly is very prolific and can reproduce four generations of offspring during the summer!

Females make their clutches in compost and manure heaps, where the heat from decay helps the hatched larvae to develop successfully. The young come out of the egg after about 5 days, after 2-4 weeks the larvae turn into pupae, from which new flies appear after another 1-4 weeks. And after 10 days, the young that emerged from the pupae are already completely ready for reproduction.

By the beginning of autumn, there are especially many zhigalok flies, so some of them fly away from farms and pastures in search of new food sources. In addition, the gradual cooling forces them to look for warm shelters in which it will be possible to calmly survive the approaching night frosts. As a result, they end up in residential buildings, where they attack a person. That's why flies bite in autumn.

Bite Features

As mentioned above, in biology and morphology, the zhigalka fly is very similar to the housefly: the body length is about 6-7 mm, the covers are gray, there are dark stripes on the chest, and dark gray spots on the abdomen. The main difference is the oral apparatus, represented in predators by a strongly elongated proboscis. At the end of this organ there are rigid chitinous plates bent back. With them, the fly rubs against the skin of its victim, scrapes off the layer of the epidermis and feeds on blood. At the same time, she injects a poisonous secret, which leads to irritation. Because of this, the bite of the fly is quite painful.

Plus, zhigalki flies are carriers of pathogens of many diseases, among the most dangerous:

• causative agents of staphylococcal infection;
• anthrax;
• tularemia;
• sepsis.

However, some diseases are zoonotic - common to animals and humans.

Pet protection

Stingers in most cases bite animals, not only cattle, but also some pets. For example, flies can gnaw on the ears of a dog, often very actively, and the owners do not know what to do to help their pet. Protecting your pet is pretty easy. Some owners prefer to use folk remedies, in particular solid oil. It has a strong repulsive smell and creates a protective oil film on the skin, which prevents the attack of flies and other insects. At night, grease can be washed off with ordinary toilet soap and in the morning, if necessary, renew its layer.

Dog owners come to the aid of special factory sprays designed to repel blood-sucking insects. There are several preparations that are suitable not only for cattle, but also for dogs and even cats. Among them:

• "Muhocid". Repellent spray, in the composition of which the substance is present - diethyltoluamide. Its action is enhanced by camphor and menthol. It is used externally and provides a comfortable stay in nature, while hunting and walking in the forest, as well as in swampy areas. But if the animal gets wet in the rain or swims in a pond, the effect of the drug stops.

  Important! Carefully study the instructions and follow the application rules. Pay attention to side effects: Muhotsid can provoke an allergic reaction, urticaria, erythema and dermatitis, so it is highly undesirable for dogs sensitive to the components of this remedy!

  What else can you treat a dog from flies? As practice shows, in the fight against flying predators, the OFF ointment brings excellent results. Only to protect against flies, it is advisable to use a remedy not for mosquitoes, but for horseflies and midges. The ointment is applied in an even thin layer on the skin, bypassing wounds and other problem areas. In addition, there is also a spray in the OFF line of preparations. If desired, you can use it, but only carefully so as not to get on the mucous eyes of the animal.

  And remember that if your dog is bitten by flies, then you should immediately look for a remedy for them. Insects often cause very serious problems, biting the tips of the ears so hard that these wounds have to be treated in a veterinary clinic.

  Why flies start to bite

  Evil individuals can attack a person, and their bite is painful. In appearance, a biting fly does not differ from an ordinary one, but if you look closely, the difference is easy to see. Most of these individuals are outside the city. Therefore, all those who like to relax in the country or in nature often encounter harmful Diptera in late August and early autumn.

  Why do flies bite and how to deal with annoying insects? Let's start with the fact that only a few species of Diptera bite, among them the Stinger. It is she who is called autumn or evil. And if someone doubts whether flies bite people, then we can say with confidence: they bite, and with a specific goal - to drink blood.

  But why do flies bite in autumn? There are several reasons for this:

  1. the number of individuals increases sharply;
  2. increased need for food before the onset of cold weather;
  3. competition between Diptera in the struggle for food increases;
  4. cold snap forces to move closer to the person.

  Usually, the Stinger fly feeds on the blood of animals, but when the number of insects increases greatly, the flies bite people. The burner is not attracted to sweets and food that a person eats, so individuals circling over the table have nothing to do with the burner.

  What flies bite, besides the zhigalki? The most famous are horsefly and tsetse. But the first prefers to live near the water, and the second does not live in our climatic conditions. So the only colored fly that bites is the Stinger.

  Her bite is far from harmless. Zhigalka is a carrier of diseases such as anthrax, relapsing fever, tularemia, yellow fever. A massive attack of insects on livestock can lead to their death.

  How to recognize a fly

  In size and shape, the predator resembles an ordinary fly. The Zhigalka is distinguished by a long proboscis with a sheen. Who does not know what flies bite with, then with this proboscis. It works in exactly the same way as a mosquito: through it, the insect sucks in blood. At the end of the proboscis are teeth. Using them, the insect bites through the skin.

  Among other differences zhigalki:

  • dense and shortened body,
  • wide spread wings
  • the presence of stripes on the abdomen.

  The development period of the insect is 2-3 weeks. This explains why the number of pests grows so much by autumn. The insect lays its eggs in manure or straw, but sometimes lays eggs directly in the open wound of the animal.

  The appearance of a fly is not too different from a room individual. But their behavior and lifestyle are different. The predator sees in a person only a source of food. If a burner appeared in the house, it means that it will bite all the time. Diptera are dangerous for babies and people with disabilities who cannot drive away annoying individuals themselves. With multiple bites, weight loss may occur. If flies bite in the fall and annoy the owners of a house or apartment, it is necessary to treat the premises.

  The bite site is treated with a soda solution, and an antihistamine is taken orally to prevent allergic reactions. If swelling and inflammation appear, you should consult a doctor.

  Now we have found out whether flies bite, and what kind of threat they pose to humans. Diptera themselves are not dangerous if their number does not exceed the permissible level, and sick animals do not live in the neighborhood, which could become a source of infection for others.

  bezbukashek.ru

  Stinger fly

  These predatory insects are very similar to flies that live near humans, their main difference is in the structure of the oral apparatus.

  We also add that ordinary flies exist due to plant foods and human waste, so their nose is not adapted to other food. But zhigalki are predators-bloodsuckers.

  
  

  As a rule, hordes of these flies can be found near farms where there are many livestock and other animals.

  We also add that with the onset of cold weather, zhigals seek to take refuge in a human dwelling in search of warmth.

  horseflies

  This type of blood-sucking insect has a distinctive feature - only females feed on blood, which, after laying eggs, become aggressive and voracious, and males only feed on nectar and plant sap.

  What is the danger of predatory flies

  Feeding on blood and making their bites, they can become the causative agent of such serious illnesses as tularemia, trypanosomiasis, anthrax and others.

  
  

  Predatory bloodsuckers, in addition to feeding on blood, have the unpleasant property of laying their larvae in the created wounds. Then the process of suppuration begins, which can end in failure, up to the need for an operation, if the necessary measures are not taken in time to treat the bite site. This factor is one of the most dangerous as a result of contact with predatory insects.

  Stinger flies are especially dangerous for infants and the elderly, therefore, if they appear in housing where there are small children or the elderly, urgent measures must be taken to eliminate them.

  Ways to fight

  How to deal with these predators? Of course, it is best to put mosquito nets, traps, adhesive tapes on the windows, constantly close the door or hang curtains. One fly swatter is not so easy to get rid of them. However, these methods are suitable for small living spaces.

  But on an industrial scale and on farms, they fight with zhigalki in more serious ways:

  • mechanical;
  • chemical;
  • biological.

  The former include all kinds of barriers on windows and ventilation openings (including mosquito nets, as well as various types of traps). These methods help get rid of adults that bite.

  Chemical preparations - insecticides - even get rid of fly larvae. These funds are used in farm premises, they process manure heaps, as well as livestock stalls.

  What flies can bite and how to distinguish biting flies from harmless ones?

  There are about 5,000 varieties of flies all over the world, and each species differs from the other in color, size, body structure and many other features. In nature, there are flies that feed exclusively on liquid plant foods. This is due to the presence of a soft proboscis that is not able to bite through the skin. Therefore, such flies are forced to feed on manure, feces, plant sap, and so on.

  

  However, there are other flies, such as the fly zhigalka. It differs from an ordinary house fly, firstly, in the structure of the proboscis, its proboscis is much longer, while it also has special bristles at the end, the proboscis itself is solid, thanks to which the fly is able to pierce the top layer of the skin - the epidermis, and drink blood. Secondly, it is also worth noting that another important difference between them is the structure of the wings. In a house fly, they are located along the calf, and the wings of a zhigal fly look to the sides. On average, the size of the gray body of the zhigalok is 7 mm.

  

  During the summer period, the females lay their eggs and the Stingers are very prolific. In a lifetime, one female is able to lay up to 400 eggs. A week after the female has laid her eggs, the eggs hatch into larvae that have a slightly white-dirty hue. After 3-4 weeks, the larvae turn into pupae, and literally after 27 days, a young stallion turns out of the pupae. In turn, the young stingray literally after 15 days of its formation also lays eggs, like other adults of the female stingray.

  It turns out that during the summer period the flies actively breed, the young generation grows up, and in the fall they the number is getting bigger, at least, even for us very tangible.

  It is noteworthy that if in mosquitoes, for example, only females bite, in zhigalok, both the male and the female take part in this.

  Most often, flies attack animals, but they do not mind feeding on human blood. Stinger flies prefer to attack sedentary people, that is, the elderly, the disabled, and even babies.

  Why do flies bite?

  Why do flies bite? The answer was partly given in the previous paragraph: by August, their population is getting larger, the competition for food is getting stronger, so the flies switch from feeding on animal blood to human blood.

  In fact, some types of flies need blood to procreate. This is the simplest and most logical explanation. They foresee the approach of cold weather and begin to bite everyone in a row, just to have time to get enough and reproduce new offspring.

  

  In the spring, flies are just appearing, biting flies begin to lay eggs, in the summer, young individuals form, and closer to autumn they become adults, capable of independent existence. Therefore, in the fall there are so many of them that they have to compete with each other in search of a victim.

  Is a fly bite dangerous for humans?

  Zhigalok bite dangerous, since these flies can be carriers of various terrible diseases, such as: polio, anthrax, tuberculosis, relapsing fever and many others. During the bite, penetrating the skin with their proboscis, the flies throw out poisonous saliva, thus, in addition to the pain from the bite, we also feel itching, burning, the skin turns red at the site of the bite.

  However, not only the bite of the zhigalka itself is dangerous, with elementary non-compliance with the rules of hygiene during meals, the larvae of these flies can enter our body along with food.

  horseflies

  Also one of the most biting types of flies are horseflies. They come in several colors: brown, yellow and gray. The size of their bodies reaches 3 cm.

  

  These flies, as a rule, live near water bodies and swamps, since they cannot exist without moisture. The habitat of horseflies is located on almost all continents of the planet Earth, with the exception of Antarctica, Greenland, and Iceland.
  These blood-sucking insects most often attack cattle and people. If in the first case both males and females drink blood from zhigal flies, then horseflies feed on blood exclusively females, males prefer plant food.

  The bite is so painful, that is, even people with normal skin types immediately experience itching, pain, burning and redness at the site of the bite. They say that there were cases when, after an attack by a large number of horseflies at once, people ended up in intensive care from a lack of blood. It's most likely a hoax.

  If we compare the amount of blood that a horsefly and a mosquito can drink, then one horsefly is able to pump out into its body a volume of blood equal to the volume of 70 mosquitoes.

  Horsefly, like other flies, is dangerous, not so much because it drinks blood from animals and people, but because during its bite it still throws out its saliva. Its saliva contains various toxic components, which just cause skin irritation. But even this is not the point, their saliva can also contain various bacteria that give rise to such terrible diseases as: anthrax, polio and many others.

  Tsetse fly

  One of the most dangerous types of flies on Earth are tsetse flies. Their habitat is in Africa. Tsetse are deadly.

  

  Remarkable is the fact that these flies are viviparous, that is, they reproduce an already viable larva.

  What to treat?

  1. The bite site should be thoroughly washed with soap, spilled with peroxide or wiped with alcohol, as a rule, this is enough to disinfect the bite.
  2. If there is swelling at the site of the bite, it is recommended to make a compress from pieces of ice.
  3. In case of itching, it is necessary to use a special anti-itch cream.
  4. If the itching does not go away, and the redness gets worse, take an antihistamine, it will remove the symptoms of the allergy.
  5. Monitor the damaged area of ​​​​skin and general condition. If the wound begins to fester or the swelling does not go away, consult a doctor.

  

  Usually a fly bite heals in 1-2 days if not combed.

  How to prevent an attack?

  There are several ways, methods of dealing with biting flies: this is a biological chemical and mechanical method.

  Biological the method of struggle involves the use of special insect predators. These predatory insects are absolutely harmless to humans and animals, but dangerous to biting flies and their offspring, as predatory insects eat them.

  Chemical the method of struggle involves the use of special insecticide chemicals that can get rid of annoying flies. These drugs are used to treat animal stalls, manure heaps, farm buildings, and so on.

  And the last method of dealing with flies is called mechanical. This method involves the use of various mosquito nets, adhesive tapes, the use of various fly protection sprays, and fly swatters.

  What flies bite

  Flies are insects that are distributed throughout the world. There are approximately 5,000 of their species. In the diet of the vast majority of these insects, the juice of various plants, decaying fruits, manure, and feces.

  Of the flies, only a small part bites. And not only a person is the subject of aggression of these insects - they also attack animals quite often. Most often it is flies-zhigalki.

  The appearance of zhigalok and their biological features are very similar to ordinary house flies, so they are always confused. The body of the insect is painted gray, its length is 5 - 7 mm.

  The main difference between zhigalok and non-predatory flies is the structure of the proboscis.

  If an ordinary fly has a soft proboscis, with which it is not able to pierce the skin of a person or animal, then the rough chitinous plates on the elongated proboscis of the zhigalka easily cope with this.

  Both females and males bite. Most often, the victims of zhigalki are animals, less often - people. During the time when the proboscis penetrates the skin, the fly injects saliva into the wound, which causes first a sharp pain, and then itching.

  During her life, the female zhigalki lays about 400 eggs in rotting plant debris or in manure. After a few days, larvae emerge from the eggs, and after 2-3 weeks, pupae form from them.

  Adults appear after 1 - 3 weeks, and by about 10 days they can already lay eggs. In general, the development cycle of the Zhigalka lasts 3 to 8 weeks, so their greatest number is reached in the fall.

  Features of horseflies and tsetse flies

  Another biting fly is horsefly. It is the largest representative of Diptera insects. The length of some individuals reaches 3 cm. Horseflies are very greedy bloodsuckers. One female can suck as much blood from a person at a time as approximately 70 mosquitoes can do at the same time.

  The bites of this species of flies are not only painful, but also dangerous: horseflies carry many infectious diseases, including such formidable diseases as polio and anthrax.

  The famous tsetse fly lives in Central Africa. In addition to the ability to bite very painfully, tsetse is a carrier of sleeping sickness.

  Autumn flies

  Stomoxys calcitrans. Outwardly, biting flies are very similar to habitual flying insects. And after their painful attacks, bewilderment arises - do house flies bite. There are differences in appearance, but they can only be noticed after careful consideration, these are:

  
  

  Habitats and life cycle of the zhigalka

  The usual habitat of the insect is pasture for livestock, a barn or paddock. Under these conditions, both a table and a house are always ready for them, that is, an abundance of warm-blooded animals as food and overripe hay or manure for reproduction and rest. The diet of the insect is only blood, and in one bite, the flies drink a volume twice their own weight.

  The breeding characteristics of bloodsuckers give the answer to why flies bite at the end of summer. Masonry, zhigalki arrange in manure or in animal litter, in the warmest places at a temperature not lower than 35 ° C. The insect goes through a full cycle of development, but the time of each stage is much shorter than that of the house fly.

  The laid eggs develop only a day and release the larva, which, in turn, successively passing through four stages of maturation, after 4 days turns into an adult insect. And in a day, the insect in the adult stage is ready for mating. The life cycle of a fly can be 7-8 weeks, and during this time, the Stinger makes 5-7 clutches of 100 eggs. When it gets colder to 10°C or lower, the burner goes into hibernation. It can overwinter at any stage - larvae, eggs and adults.

  Why do flies bite in autumn?

  The onset of a cold snap makes zhigalok look for warmer places and during this period they may appear in the house. How flies bite is remembered for a long time. Unlike an ordinary flying insect, chitinous plates are located at the end of the proboscis at the end of the proboscis. With them, she scrapes the skin to the blood vessel and, before eating, injects a poison that prevents blood clotting.

  Both females and males attack. By the end of the summer period, the insect population is quite significant and the person who falls under their arm begins to wonder whether house flies bite or some others. The bite of this insect causes burning pain, followed by swelling. In addition to painful sensations, the burner carries many pathogens of dangerous diseases:

  • sepsis;
  • tularemia;
  • trypanosomiasis;
  • anthrax, etc.

  For parents, if their children were attacked by a stinger, it is necessary to urgently consult a doctor, and not to think about whether the flies bite in August in a city apartment.
