Good day, dear friends. Trick question: what quality of an insecticide, besides its effectiveness, is your priority? For me personally main role Convenience and ease of use play a role.
So in today’s article I decided to review the most convenient, in my opinion, means. If you don't know how to use a cockroach syringe yet, welcome to this blog.
I will tell you about the most popular and effective means, which come in a syringe. You will learn everything about their composition, the duration of the preventive effect and other features. Let's discuss the benefits of these tools, and at the same time how to use them correctly to achieve the best results.
What is a cockroach syringe?
As you understand, the syringe itself is nothing more than a convenient package. The whole secret of effectiveness is in the substance that is inside this very syringe. Most often, gel insecticides are placed in such packages, which directly fight cockroaches.
The composition of the gel depends on the brand of the drug - we will discuss all this below, but for now I will tell you why I give my preference to the syringe when choosing an insect repellent:
- Convenient packaging eliminates leakage, spillage or any other misunderstanding during disinfestation.
- The thin long spout helps me get into the most secluded nooks and crannies of my kitchen.
- Thanks to the pump, the product is dosed very evenly and economically - you will not miss those areas that need to be treated, and you will not fill with gel those that do not need to be treated.
- Pets have no chance of eating the poison unless they are able to swallow the syringe whole.
- The use of a syringe does not require the use of special personal protective equipment.
- The sealed packaging prevents the release of toxic fumes, so the product can be stored anywhere (but not in the refrigerator, of course).
- If you have not used up all the gel, you can safely store it until the expiration date - the design of the syringe does not allow the product inside to dry out.
As for the shortcomings, they can only be found in individual products, but we will discuss this below. I propose to take a closer look at the main brands of insecticides produced in syringes. 
Trap Sturm gel paste
The main component of the product is diazonin. It is an enteric insecticide that kills arthropods through a nerve agent. The volume of the syringe is 30 ml, it is enough to treat 50 square meters.
After 2-6 weeks, not a trace of the poison will remain - under the influence of oxygen and ultraviolet radiation it breaks down into harmless elements. In addition to the poison itself, “Trap Sturm-gel-paste” contains:
- gelling agent;
- stabilizer;
- preservative;
- food attractant.

Thanks to this composition, the gel does not dry out and remains effective for a month. This means that re-processing is not necessary. The manufacturer promises complete extermination of the colony after 3 days and a preventive effect for up to 6 weeks.
Absolute
Transparent gel with a light brown tint, which is available in a 20 ml syringe. The main component is chlorpyrifos, an enteric poison from the group of pesticides. Once in the body of a cockroach, chlorpyrifos blocks the transmission of nerve impulses, as a result of which the insect dies from paralysis and suffocation.
With one package you can treat 30 square meters, so it’s better to buy several at once. Moreover, a special fatty base protects the gel from drying out, and a preservative preserves the activity of the poison.
“Absolute” can save you not only from cockroaches, but also from woodlice, silverfish and ants, including garden ants. The product remains effective for 4-6 weeks, after which it must be removed. For prevention purposes, you can periodically lay out substrates with a drop of poison in especially secluded corners. 
Global
This product stands out from its analogues due to its composition, namely its bait. While other preparations contain artificial flavors, the manufacturers of Global gel use natural honey and chocolate. I don’t know how practical this is, but there’s no arguing about the effectiveness of the syringe. The fatty base and preservatives will keep the formula active for 2 months.
Brownie Proshka
Thick gel paste white or beige color based on fipronil. Once in the body of a cockroach, fipronil blocks the production of an enzyme necessary for normal operation nerve endings. As a result, the insect loses the ability to breathe and dies from lack of oxygen in vital organs.
Fipronil is popular with insecticide manufacturers, and here's the secret.
One individual does not die instantly after contact with the poison, but lives for several more hours. During this time, she manages to infect a dozen healthy Prussians, which provokes the extinction of the entire colony along the chain.
“Brownie Proshka” will destroy nasty arthropods in 1-3 days and will protect your home from repeated invasion for about another month - that’s how long the gel remains effective. 
Clean House
A thick transparent gel based on chlorpyrifos that will protect your home from cockroaches and ants. Due to its consistency, the product remains quietly even on vertical surfaces, so if necessary, you can treat them too - for example, tiles in the bathroom or the backs of paintings.
Complete destruction of the colony occurs in 3-5 days, while the preventive effect lasts 2-2.5 months. But it's not main secret"Clean House"

You probably noticed that I am writing about the duration of the preventive effect of each drug from the perspective of the need for re-treatment. The apartment really needs to be sprayed twice to kill the newly hatched nymphs.
But with the “Clean House” gel, you can allow yourself to relax and not have to repeat the disinfestation procedure. Its peculiarity is the concentration of chlorpyrifos - due to the increased content of poison, the drug even affects oothecae, destroying unborn larvae.
True, this feature leaves an imprint and not the process of using the gel. To protect your skin from allergic reaction or chemical burn, you will have to wear rubber gloves. And make sure that children or pets do not try to eat the poisonous substance.
Dohlox
Another drug based on fipronil. The action of this component is interesting not only for its delayed effect. You may know that cockroaches are prone to necrophagy, that is, to eating dead brothers. So the Prussian, who died from fipronil, himself becomes poison and kills those individuals who decide to feast on his remains. 
“Dohlox” is produced in a syringe weighing 30 g. One package will be enough if there are few insects in the apartment or they have just appeared. If the Prussians multiplied and became so insolent that they began to move from the kitchen into living rooms This means that the amount of the drug needs to be significantly increased.
As for preventive action, “Dohloks” can boast of 2 months of protection of your apartment from the invasion of Prussians. Be sure to wear rubber gloves during processing to protect your skin from chemical burns. The concentration of fipronil, although not too high, is still sufficient to cause serious irritation.
Combat Roach Killing Gel
A very effective drug based on pyrethroid poisons, which is available in a black plastic syringe weighing 30 g. Calculation required quantity The product depends on the number of insects, but on average one tube is enough for 50 square meters. “Kombat” is loved because it is non-toxic and will not harm people and their pets, while completely destroying the entire colony of arthropods.
In addition to the poison itself, the gel contains a food attractant to attract insects, a fatty base that prevents drying, and a special substance, hydramethylnon, which prevents cockroaches from developing resistance to the poison. This means that the drug remains equally effective even with prolonged disinfestation (this happens when high degree infestation of the apartment).
The fatty base does not allow the gel to dry out, so it remains effective for 3 months - as you can see, it is still the absolute leader in the duration of the preventive effect on our list. This means that you will not have to re-treat the apartment, since the newly hatched nymphs will be killed by the same gel as their parents.
Dohlox traps are black plastic washers containing a poisonous treat that attracts cockroaches thanks to the scents. The washers are packed in cardboard boxes, then in cellophane film and in a large package. Each pack contains six traps - this number is more than enough to get rid of cockroaches even in the most spacious apartment. On the back of the packaging you will find a clear and detailed instructions by application. Read it carefully and follow the manufacturer's recommendations to achieve the desired effect and forget about the Prussians for a long time.
How do traps work?
As already mentioned, inside the plastic washer there is the insecticide fipronil along with food attractants that attract insects. The cockroach that first tasted the poisoned treat will carry some of the poison into the nest on its legs, antennae and abdomen and infect its fellows. In addition, it is customary for Prussians to eat dead relatives, so this is also a unique way of spreading poison - by eating a poisoned individual, other cockroaches will also die. 
The “domino” principle will destroy the entire colony of vile insects within a day, maximum two. In this case, the traps do not need to be removed - a few pieces can be left on the mezzanine or near the trash can as a preventive measure for re-infestation by cockroaches.
What are the advantages of Dohlox traps?
If you are in doubt and cannot choose between gel and traps, I will talk about the advantages of the latter to make your choice easier. So, traps are distinguished by the following factors:
Why do I have cockroaches?
It is no secret that most often cockroaches infest those apartments in which the owners are not too concerned about cleanliness and order. Uncollected crumbs, a full trash can, dripping faucets, dirty dishes in the sink, half-eaten food left on the table - all this creates ideal conditions for the prosperity and reproduction of nasty creatures.
The jelly-like substance is sold in tubes equipped with a convenient spout, as well as in syringes, which are very convenient to use, primarily because make it possible to apply them in small portions and precisely even in hard-to-reach places. Compared to liquid preparations, gels are less toxic, however, their effectiveness does not suffer from this in any way. Insecticide included in the preparations characterized by a nerve-paralytic effect. When ingested, it can block nerve impulses, then immobilize and cause death. It has both contact and intestinal effects. But the insecticide in the substance is no more than 2%. This is quite enough. To attract food, food attractants are added to the poison - in other words, flavorings. The composition is made on an oil basis. It does not allow the substance to dry out quickly, so it remains in working order for a long time without reacting to any sunlight, nor on the room temperature. To protect the bait from unwanted eating by children or pets, it is often made bitter. However, this does not stop insects from eating. For reference! The aroma attracts pests. They eat food that is pleasant to them, and carry away the remainder of the composition on their paws. It should be noted that death does not occur immediately, so the Prussians cannot suspect anything special. The death of the colony begins in a couple of days when most of it is already infected. The remaining individuals die out gradually, especially since the bait continues to remain on the treated surface. Important! Store the tube or syringe of gel at normal room temperature in a dark place away from animals and children. To use the drug, no special equipment required. All you need is rubber gloves and a gauze bandage. Advice! Using strips of cardboard will make cleaning up much easier once the goal of eliminating household pests has been achieved. Insecticidal gel against cockroaches is considered one of the most effective ways getting rid of insects. It is convenient to apply to the surface, it is practically odorless, has low toxicity to humans and has a fairly long period of action. It is also important that the gel base provides strong adhesion to the surface, preventing the spread of the toxic substance throughout the room, and removing the remaining drug will not be difficult with a regular damp cloth. Despite the fact that now you can find a huge number of different gel-based drugs on store shelves, their composition and principle of action are not very different from each other. Which one will be the most effective against mustachioed invaders? To understand this issue, let's consider the main ingredients included in the insecticidal gel. Any gel against cockroaches has the following approximate composition: The main active ingredient is a contact or intestinal insecticide. This could be chlorpyrifos, hydramethylnon, fipronil, lambdacyhalothrin or any other chemical drug, having poisonous properties for insects. IN general composition it occupies no more than 2% of all components of the gel. Moreover, the stronger the poison, the less quantity is used. For example, Domovoy contains 0.5% chlorpyrifos, and Cleanbate gel contains 2% hydramethylnon. It is also often practiced to combine two insecticides in one tube. This way more high efficiency drug. Bait is an essential ingredient in any insecticidal gel. With its help it is possible to attract insects. Often these are aromatic substances - attractants. Depending on the manufacturer, the gel may also contain additional elements. For example, a bitter substance that prevents a child or pet from eating it. Interesting fact! Despite the fact that cockroaches are equipped with fairly powerful jaws that can bite off a piece of dried bread crust, they still prefer food with a liquid consistency. These preferences were taken into account when developing insecticidal gels. The principle of action of the insecticidal gel is based on the spread of poison among a colony of insects. A cockroach, coming to the smell of the bait, eats the drug and goes to its nest, carrying away particles of the toxic substance on its paws. This is how the insecticide spreads. After its death, the insect becomes food for its fellow tribesmen, poisoning them. Gels can be called long-acting agents, since quick effect you won't get it from them. However, this property provides a stable result, since the insecticidal substance slowly but surely spreads to the entire colony, including newly hatched larvae. The validity period of such a drug is 1.5-2 months. after application to the surface. Insects begin to die within 1-2 days after eating the poisoned bait. Advice! In order to apply the gel to the vertical surfaces of walls and furniture without staining them, you can use masking tape. At the end of its validity period, it is simply deleted. Cockroach gel is usually produced in a container shaped like a syringe with a thin long spout. This packaging makes it easy to apply the drug to any place, even the most difficult to reach. Some gel-like products can also be produced in tubes, for example, Global Gel-paste. We talked about its use in a separate article:. By squeezing out the contents of the syringe, the gel is applied in dotted lines to the baseboards around the perimeter of the apartment, as well as around places where insects are likely to live. You can also apply the drug to vertical surfaces and walls, having previously protected them with adhesive tape or tape. The distance between drops of gel should be no more than 1 cm. However, it can be increased to save up to 4 cm in case of low contamination of the apartment. The gel remains active for 2 months. After this period, the processing can be repeated. You should not use one drug more than twice, as cockroaches may become accustomed to it. You also need to be careful when applying to avoid possible contact of the toxic substance with the intestines and skin. Interesting fact! Cockroaches can go without food for about a month. They tolerate the lack of water more difficult and die within a week. Therefore, in order for the effect of the gel to be more complete, it is necessary to block the insects’ access to water. On store shelves you can find gel preparations from the most different manufacturers. Let's look at each of them in more detail. Domovoy gel against cockroaches contains chlorpyrifos. This is a contact-intestinal insecticide that causes paralysis of insects when it comes into contact with them or enters them through the food tract. The preparation also contains a gel-forming base, preservative additives and bait. By appearance the gel is a colorless viscous mass, practically odorless. The drug is produced in tubes with a 30 ml dispenser. This syringe is enough to treat about 50 m2 of area. The cost of one package does not exceed 40 rubles. Despite its more than affordable price, Domovoy gets rid of cockroaches quite effectively. It begins to show its effect already in the first day after application. After a week, you can notice a significant reduction in the population, and after a month you can forget about cockroaches. The drug has a residual effect for 2 months. After this period, the treatment is repeated as necessary. Absolute gel against cockroaches also contains chlorpyrifos as a poisonous substance, but is more powerfully packaged in 125 ml tubes. This amount is enough for 150 m2 of surface area to be treated. The color of the drug can range from colorless to light brown. The consistency is viscous, capable of maintaining its structure for quite a long time. The cost of one package ranges from 80 to 130 rubles, depending on the region. Apply the preparation with a 2 cm dotted line, alternating it with sections of the untreated surface of the same length. Cockroaches die 1-3 days after eating the bait; the gel retains its residual effect for at least 2 months. According to the degree of danger, Absolut-gel belongs to the 4th class of toxic substances. It is approved for use in children's and medical institutions. However, as with everyone toxic substances, use caution when handling it to ensure that it is not accidentally ingested by children or pets. To do this, the drug is applied to the surface in hard to reach places, cracks, cracks and under baseboards. You can also squeeze the gel onto pieces of paper and spread them around the room overnight. Gel Clean house against cockroaches and ants can be purchased for 40 rubles. It is sold in a 35 ml tube. This amount is quite enough to treat an apartment with an area of 40 m2. If the room is heavily infested, the consumption of the product is doubled. The effect of using the drug becomes noticeable 2-3 days after application. At this time, you can see the corpses of dead insects and cockroaches, stunned by poison, crawling out of their shelters. Important point– it is necessary to block arthropods’ access to water in order for the drug to be as effective as possible. Reprocessing may be required when . It is carried out no earlier than 3-4 weeks after the first. Clean home - a remedy for cockroaches that has greatest number conflicting reviews on the Internet. It helps some, others write about its uselessness. However, if you look at its composition, you can see that active substance– still the same chlorpyrifos. And this is a fairly powerful insecticide that has proven itself over many years. The gel is produced in an easy-to-use syringe with a dispenser-spout. It is convenient to apply and easy to use.
