Where do cockroaches live in the house? How to find their nest, what to look for?

One of the adaptive survival mechanisms of the cockroach family is the ability to hide in the corners of the apartment. If the insects freely came out into the open areas of the apartment, it would not be difficult to destroy them. But hiding away from the eyes of their owners, Prussians have a chance to survive even after a “chemical attack” if the stream of chemical does not enter their habitat. How to detect places where indoor pests accumulate before they multiply exponentially?

Where do cockroaches live?

As a rule, mustachioed pests appear in homes with poor sanitary conditions. Open trash cans, scattered food scraps, dirty countertops, unwashed household appliances - all this attracts cockroaches and provides them with a comfortable existence in human homes. But even clean residents can become victims of barbel attacks.
Cockroaches often move into apartments from dirty entrances and basements, as well as from neighbors whose living space is already infested with pests. Garbage chutes and various landfills are ideal habitats for cockroaches. However, in an apartment they prefer to hide in dark, secluded places located near sources of food and water. It can be:

cabinets and crevices under sinks and other plumbing fixtures;
cracks in baseboards;
heating pipes close to the wall;
section of the drain pipe to the siphon;
cluttered rooms, such as a closet or closet;
cracks behind furniture;
Appliances.

Household appliances are one of the most favorite hiding places for cockroaches in the apartment. The back walls of the refrigerator, stove or microwave are favorite places for pests. Often, longhorned beetles populate these places already in the store warehouse. A buyer who does not suspect anything about the presence of longhorned beetles in a new household appliance brings the product home, and a few days later notices insects in the apartment. Behind the back walls of household appliances, cockroaches set up their nests and breed in incredible quantities, since no one disturbs them there. Sometimes insect nests are found in a drain tank, an old-style TV, or a computer system unit.

If there are cockroaches in the apartment, then most often their nest is in the kitchen. Anything can be a haven for pests. This includes kitchen cabinets and space under the sink or countertop.

Longhorn beetles can be found in ventilation ducts and on hood filters, in the drain hole, behind decorative protrusions, in flowerpots and even in dishes that are located on the top shelves.

While it is difficult for pests to survive without water, they can survive for quite a long time without food. After general cleaning in the kitchen, cockroaches may not leave the home, but move to other rooms. Often cockroach nests are found behind wallpaper that has peeled off from the walls. There, barbels not only hide, but also feed on paper and glue residues.

Can they appear from the sewer?

At first glance, the idea seems strange, but if you remember that in some countries you could sometimes find a whole boa constrictor along the sewer lines in the toilet, then there is no need to talk about cockroaches at all. Moreover, they can crawl through not only the toilet, but also other similar communications that have fairly large gaps. This could be a sink or even a bathroom.

Perhaps it cannot be said that they are in any way different from other standard varieties of cockroaches.

However, the most unpleasant neighbor in this case will be the black cockroaches that crawl out from there. If in a normal case you can see cockroaches the size of a human fingernail, and a child’s fingernail at that, then a black cockroach will be 5 times larger and more terrible. Fortunately, pests don’t particularly like to crawl beyond the place from which they appeared, and therefore they can most likely settle behind the sink or in secluded places near the toilet.

Also, we will briefly talk about the reasons for their appearance, and even in this way. In Russian cities, residents of Moscow most often suffer from the problem of sewer cockroaches. This is most likely due to population size. Insects emerge most often in the summer, but not due to climate change and rising temperatures. They simply multiply to such an extent that the current food is not enough for each such resident, and therefore they begin to try to get to the surface. On one of these beautiful days you can see this terrible sight. Otherwise, they are no different from ordinary cockroaches, and therefore the methods of fighting remain the same.

Types of cockroaches in the apartment

At home you can find several types of parasites:

The red cockroach (Prusak) is a small insect with an elongated oval body 10-13 mm long. The color is reddish-yellow, there are wings. The larvae are dark brown, the ootheca (the place where eggs are laid) is 6-8 mm, light brown. The cockroach is fertile and takes care of its offspring. Which has a positive effect on its numbers.
The black cockroach is an adult 20-26 mm in size, the body is flat, the color is black, shiny. The larvae are also black, the capsule with eggs is brown and ribbed. In terms of the number of identified colonies, it is inferior to the Prusak, but surpasses it in size. Insects prefer the lower floors of houses and garbage chutes.
The American cockroach is a brown or brownish insect, 28-44 mm long. Nymphs are red-brown, the egg cocoon is in the form of a quadrangular glossy capsule. The species is not widespread like the Prussian, but is successfully developing new territories. The lifespan of adults is up to 3 years.

Signs of cockroaches in the house

Timely detection of pests in the premises will help to deal with them faster. The fact of the presence of cockroaches in it is carefully hidden from people who rent an apartment. Being close to insects causes many problems; it is advisable to detect their presence as early as possible. How to find out if there are cockroaches in an apartment? It is worth inspecting the rooms and paying attention to the following signs:

Dark spots on walls and furniture surfaces left by insect excrement.
Pieces of chitinous cover scattered after molting.
Ootheca (capsules with eggs) on the floor and in secluded places.

Any sign is enough to verify that the premises are infected. When searching for a nest in an apartment, you will have to use physical force - move the refrigerator and gas stove, remove wall cabinets. Pests traditionally gather in these places. There the dark tracks merge into spots, a large number of chitinous skins shed by the larvae.

Advice. At night, go into the kitchen and turn on the light; if there are cockroaches in the apartment, they can be detected visually. It's worth looking into cabinets and drawers.

If insects run along the floor or wall during the day, then their population is large. A female Prussian lays 38-50 eggs at a time and produces about 400 larvae during its life cycle. Female black cockroaches lay up to 22 oothecae with 10-20 eggs. The insect colony increases at a rapid rate, especially at high temperatures. It is necessary to immediately begin to destroy the parasites.

How to detect a cockroach nest?

Pest nests are large concentrations of individuals. The place itself is quite dirty and unsightly, because food debris, chitinous shells, cockroach feces, and carcasses of dead individuals accumulate there. It is difficult to discover where cockroaches that have just appeared indoors are hiding. However, their presence can be tracked by the following signs:

an unpleasant smell of mold appears in the apartment;
a crunching sound is heard at night;
Dark brown dots appear on walls and kitchen surfaces.

When there are a lot of insects in the house, it will not be difficult to detect them. It is enough to suddenly turn on the light in the kitchen at night, and the pests will run to the place where they live. The areas of their greatest accumulation can be determined by the amount of excrement. If you don’t want to wait for night, then you can conduct a simple experiment when it gets dark outside. You need to leave a shiny candy wrapper on the kitchen floor and wait for pests. After the candy wrapper starts rustling, you can turn on the light. The cockroaches will scatter, indicating the path to their hiding place.

How to destroy a nest?

The decision to crush some of the insects with slippers will not be a mistake, although in any case you cannot do without insecticides for cockroaches . Such a step will make the work of chemicals easier, since the population will decrease slightly. If you are lucky, the larvae (nymphs) will be crushed, which are potentially the main successors of the cockroach genus .

After the initial intervention in the quiet life of the Prussians, you need to use one of the drugs :

Aerosol . It has a weak effect when fighting large colonies of cockroaches, but is ideal for killing individual insects. Reid has proven himself well.
Gel. This is considered to be the most effective insecticide option. Not only does such a paste kill the entire colony of Prussians, but it also has a very long-lasting preventive effect. Users speak well of the Clean House gel.
Traps. They are intended more for the prevention of infection, but they are also good for destroying small populations. Many people prefer the Raptor, try it too.
Chalk. The number of cockroach colonies is reduced, prevention is provided, and they are cheap. What else is needed? By the way, we recommend trying Mashenka, known since Soviet times.

Please note that some of these insecticides may be harmful to humans and pets . Compliance with basic safety rules when working with them is necessary. If everything is done correctly, then there will be no trace of cockroaches left , and comfort will return to your home and bring with it cleanliness!

Larval stage

Cockroach larvae have a very beautiful name - nymphs. These insects bypass the pupation stage and are born fully viable. The mere fact that 3 days after birth the mother stops caring for the young speaks volumes about their independence.

Externally, nymphs differ little from their parents. They are only smaller in size and have a darker color (sometimes lighter, depending on the variety and environmental conditions).

At the same time, the larva goes through several molts - its body grows quickly.

3-4 months after birth, the nymph becomes an adult cockroach capable of procreation

That is why it is important to destroy the insect at this stage, because each of the grown Prussians can produce up to 1000 offspring during the year, this is a very large indicator even for insects! The situation is somewhat clouded by the fact that modern insecticides have a bad effect on eggs that are securely hidden in the ooteca

The situation is somewhat clouded by the fact that modern insecticides have a bad effect on eggs that are securely hidden in the ooteca.

But this is not a problem - the larvae are very sensitive to chemicals, so there will be no problem with them. You can use the same means as when fighting adults, for example, Clean House traps and Raid aerosol.

Important. There is no need to specifically look for nymphs; they live together with adult cockroaches. If you suddenly come across these in your kitchen, press mercilessly - they are not yet ready to reproduce, so the active extermination of the larvae can significantly reduce the size of the colony in the future!

Popular means of struggle: Tiuram, Executioner, folk remedies, Tsifoks, Sinuzan.

Routes of penetration

Arthropod pests usually enter an apartment in various ways. It is important to know where the insects are coming from so that you can take appropriate action.

Main sources of penetration:

Through a sewer pipe.
Along the ventilation shaft.
Through the entrance.
Through holes or cracks that are present in windows and doors.

Pest nests are brought into the house along with used equipment or things. If you decide to buy a used laptop, then you should first inspect and clean it.

In multi-storey buildings, cockroaches have been observed to infiltrate from neighbors who do not comply with sanitary and hygienic standards. In this case, you must contact the appropriate organization that conducts inspections.

Secluded places

Above we talked about the main places where you can check for a cockroach nest.

But if you want to go further and check even inaccessible places, you can use special devices, such as a steam generator with a narrow nozzle. We simply place the tube in this place, turn on the device and wait for the result. Even if there is someone there, he will definitely show up. At the same time, we advise you to immediately arm yourself with weapons to kill cockroaches!

Reproduction process

If you have ever found a cockroach nest at least once in your life, this picture will stay with you for a long time. How many of them are there: tens, hundreds, thousands? It seems that the population of these insects is growing literally before our eyes! But how quickly do cockroaches actually reproduce?

In order for a new generation to appear, it is necessary to have two sexually mature individuals, male and female, since they reproduce sexually. The female is slightly larger in size and secretes odorous substances, inviting the male to mate, after which she lays eggs.

This is interesting!
Most species of cockroaches have wings, but the need to use them in an apartment has long ceased.

Over about 2-3 weeks, the eggs develop into the first larval stage in a special protective capsule called an edema, which the female carries with her for a while and then leaves in a safe place.
When the first stage of larval development is reached (and this can take more than 3 weeks), if environmental conditions are unfavorable, the juveniles leave the edema. If when you hear the word “larva” you imagine something inactive and worm-like, then cockroach larvae will surprise you. They are called nymphs and look like a miniature version of the adult. Accordingly, they eat and run around the apartment just as actively.

By the way
The older the domestic cockroach, the lighter its color: if adult individuals - imago - have a reddish color, then the larvae are almost black.

Cockroaches undergo an incomplete process of metamorphosis: there is no pupation stage. And they grow with the help of molts, of which there are 5-7 throughout the life of the larvae. Each molt brings the individual closer to sexual maturity, but how quickly this process takes place depends only on external conditions. If the nymphs are in a warm and humid place with an abundance of food, they will be ready for fertilization after 4 months. The colder, drier and hungrier it is, the longer it will take the insect to reach sexual maturity.
A sexually mature individual of a domestic pest lives for about 7 months. How often can she give birth to new offspring? The problem is that after the first fertilization, the female stores the male's reproductive cells for subsequent clutches and, under favorable conditions, will not miss the opportunity to lay eggs about twice a month. On average, during her life she manages to lay 10-15 clutches of 15-20 eggs in each edema.

By the way
There are viviparous species, such as Madagascar cockroaches, that can be kept as pets. This system is also characteristic of some other large tropical species.

It turns out that red cockroaches reproduce not too quickly, but in geometric progression. And in order to start a nest, all it takes is one sexually mature female, who accidentally wandered into your apartment and found the conditions in it suitable. Adding fuel to the fire are the larvae, which look almost the same as the adults. But why did they find your home attractive?

Features of the ooteca

The presence of a special capsule is one of the features of how cockroaches reproduce.
Ootheca is translated from Greek as “egg storage”. It separates future individuals from the external environment and has the following purpose and features:

Madagascar hissing cockroach - larvae

inside this capsule, eggs develop within 30 to 75 days; the higher the temperature and humidity, the faster the insect hatches;
from one ootheca, as many cockroaches will hatch as there were eggs in it;
a reliable capsule shell ensures proper development of the larva and high survival rate of individuals;
the capsule can withstand temperatures from -5 to +50 degrees, and is also not afraid of disinfectants;
on average, one female lays up to 35 future cockroaches in such a capsule 4-5 times in her life.

After the larvae mature, the wall of the ootheca bursts, and the small insects quickly leave their shelter.

Conditions for reproduction

Knowing how domestic cockroaches reproduce may be useful, but I would still like to understand why the nest appeared on yours and not on your neighbors. To find the answer to this question, just look at the typical habitats of cockroaches in the wild.

Warm. Cockroaches are typical inhabitants of the tropics, and the fact that in our region they are common only in residential buildings is proof that they were brought to us. They say that they were accidentally brought along with bales of things by soldiers after the war with Prussia (hence the name “Prussian”), but they obviously got there from warm countries and assimilated into homes without any problems.
Dampness. Imagine the tropics and you will certainly feel that humidity, which makes being outside like visiting a hammam. It is in these conditions that, for example, Madagascar cockroaches live. That's why they will definitely appreciate leaking water pipes, and simply rooms with high humidity. If you are worried about mold on the walls, then with a high degree of probability cockroaches will not keep you waiting.

This is interesting
There are even several species of domestic cockroaches, and there are thousands of varieties in the world.

Darkness. Why is the nest not located in a visible place? Everything is simple here: not only are cockroaches in the wild nocturnal insects, but also staying in an open, illuminated space increases the chance of being eaten by some predator. That's why a cockroach that you accidentally see on a table or on the floor is always in a hurry somewhere. He hurries to hide.
Nutrition. Well, without food, cockroaches would not survive. Previously, cockroaches in the house were even considered a sign of prosperity: it meant that the owners did not collect crumbs. However, later cockroaches began to be associated with uncleanliness. They say they created some dirt and that’s where the insects live. This is not entirely true: it’s difficult to keep track of every crumb, and you won’t be taking out the trash can every couple of hours. But the amount of food available does determine the size of the existing population.

By the way
Nutrition is important for nest expansion, but a single individual can live without food for about 20 days, so it is quite difficult to starve a cockroach.

If there is a place in your apartment that meets these cockroach requirements, a nest will appear there very, very soon.

Warnings

Insecticides, cockroach baits and other chemicals can be toxic to people (especially children) and pets, so pay close attention to label warnings and follow the manufacturer's directions to the letter.
When spraying chemicals in a kitchen cabinet, hold your breath and spray quickly, or buy a respirator for this purpose. By purchasing a sprayer with a pressure blower, you can work faster.

Contrary to popular belief, cockroaches do not run throughout the apartment day and night, poisoning the lives of its warm-blooded inhabitants.

It is because of this that some housewives

They make a serious
mistake by treating all open surfaces
in the house with insecticides, forgetting that they simply do not appear in such areas. Where are cockroach nests located, how to find and destroy them?

To answer this question, you need to remember the lifestyle of these harmful insects. If without food

A cockroach can
live peacefully for a month
, but
the lack of water
will become fatal for it
within 2-3 days
.
Therefore,
Prussian
nests as close to water sources as possible
:

kitchen sink;
Dishwasher.

Insects are rarely found in the bathroom, since the presence of water, although important, is not a fundamental factor in choosing a place to live

spaces under baseboards and door jambs;
gaps between the wall and wallpaper;
cracks in walls and floors;
back surfaces of furniture.

It’s a paradox, but sometimes Prussians can be found even in the refrigerator,

and this despite the fact that low temperatures are deadly for them!
It goes without saying that they hide as close as possible to the heat distribution
unit; sometimes it gets a little hot there, but if cockroaches appear in the freezer and food compartments, it is only by accident.

What do they eat?

Housewives who keep their apartments perfectly clean do not understand why the number of pests is constantly increasing. The main reason is that insects are not picky eaters. Therefore, they eat not only organic remains and food. Their diet includes plants and books, soap and leather goods.

Scientists note that domestic species quickly adapt. They do not require special nutrition. If they do not detect organic remains at night, they gnaw on the epidermis of a sleeping person.

If you are wondering whether a domestic cockroach can get into the ear, then otolaryngologists have noted such cases. Pests enter the auricle in search of shelter.

The only thing insects cannot do without is water. If you limit access to liquid, the fight against them will be more successful.

What can be done to stop cockroaches from multiplying?

There are a sufficient number of insecticides that fight these insects very successfully if used correctly. But poisons alone are not enough: in order for your apartment to cease to be attractive for reproduction, it is advisable to fulfill a number of conditions.

Frequently check and treat dark and damp nooks and crannies with poison as a preventative measure, especially if you know that cockroaches may return or pass to you from your neighbors.
Control the humidity in the apartment, especially if you live in a region with high air humidity in general. This can be done using a regular air conditioner.
Do not leave food in the open that cockroaches could eat, and get rid of the habit of eating without a plate and in bed: this is how crumbs spread throughout the apartment in large quantities.
Do not forget about repeated treatments: the swelling does not allow chemicals to pass through, so the nymphs that appear after the first treatment will be absolutely healthy. And given that they can regulate the speed of development themselves, it will not be difficult for them to wait out difficult times in the capsule.
If you want to get rid of the nest quickly and without poisons, you will have to turn off the heating for a while in winter, killing all the cockroaches at sub-zero temperatures (even at -5˚C they will die almost instantly).

Without treatment, it is quite difficult to deal with an existing large nest, but once you get rid of it, you can use the information received to ensure that your apartment will never again become a haven for these insects.

Professional approach

These are radical methods that most often involve the use of aggressive substances that are harmful to the health of humans and pets, so you must act carefully. But there are also safe devices that do not have special requirements for operation.

Purchased funds

There are products on sale that have been used by humanity for decades. But you can also find innovative developments. Main types:

Syringes with gel. Safe for health, quickly applied, easily washed off, but destroys only those individuals that are already crawling (does not apply to eggs). The gel will have to be changed once a week. To use, simply squeeze the gel-like mass onto a piece of paper or any surface using a dotted method. Well-known brands - Raptor, Dohloks, Absolut.
Crayons. These are Mashenka, Brownie, Tornado, etc. Pencils are harmless; they are used to draw solid or dotted lines in places where there are large concentrations of cockroaches.
Traps. These are structures with holes containing bait substances inside. An insect that gets into a trap spreads poison throughout the family. The most famous brands are Kombat, Raptor, Dohloks.
Powders and granules. They scatter over surfaces, consist of substances that are poisonous to insects, and do not destroy larvae. The powder needs to be renewed twice a week. Example - Super Fas, Phenaxin, Clean House, Absolute.
Aerosols. They contain elements harmful to humans, so after spraying on surfaces (walls, tables, floors, etc.), you must leave the house for at least 2-3 hours, then thoroughly rinse the surfaces with which you come into contact. Popular brands are Get, Raptor, Dichlorvos, Regent, Ultra Magic.
Ultrasonic repellers. These are devices that operate on mains power or batteries. A mechanism is built inside that emits ultrasonic waves, to which only insects and small rodents react. The device causes cockroaches to escape from the room. If they do not have time to do this, then the nervous system is affected, after which paralysis and death occur. There are such brands on sale as Typhoon, Rexant, Tsunami, Tornado.

Calling specialists

If you do not have the opportunity or desire to hunt cockroaches on your own, or for some reason it is impossible to remove them, contact a special service. But before that, talk to the residents of the apartment building, since the destruction must be comprehensive.

Otherwise, after treating your territory, the pests will move to other apartments and then return again. You can contact the city SES, especially if there are cockroaches in the basement. In this case, the city authorities provide the service free of charge.

You have the right to choose a private pest control company, but you will have to pay at least 2-3 thousand rubles. How the procedure goes:

Specialists treat the entire room using steam and chemicals.
You leave the apartment for 5-10 hours, depending on the means used.
Upon return, thoroughly wet clean.

Be sure to remove dishes, towels and other items first. Cover the furniture tightly with film.

How to get rid of housing

So, when insects are detected, the first and most pressing question is the following - how to get rid of black cockroaches in an apartment. It should be noted that common folk methods, for example, the use of orange peels or cloves, are not an effective measure.

To kill insects, only chemicals should be used. You can do this either yourself or by calling professional exterminators.

Black

If black cockroaches appear in a residential area, first of all you need to find out how they got into the apartment. You should carefully examine the sewer pipes, ventilation grilles, that is, all communications that connect the apartment with neighbors’ homes or basement floors.

If insects enter through an apartment located behind a wall, it is recommended to cover the ventilation openings with fine mesh grilles. If you plan to treat the premises with chemicals, it is advisable to do this at the same time as your neighbors. If residents of a nearby apartment have already carried out the treatment, it is necessary to find out exactly what chemicals were used. When using the same product repeatedly, its effectiveness decreases significantly.

Insects can also appear in a private home. Methods for getting rid of uninvited guests are standard. However, you can use simpler methods. So, how to get rid of black cockroaches in a private home?

If insects appeared in the winter season, it is enough to simply freeze the room, that is, turn off the heating and leave the house for several days. This measure is quite sufficient for the death of colonies.

Sewer

Black cockroaches especially often crawl out of sink, bathtub, and toilet drains at night. This behavior is due to the fact that insects cannot exist without water. In order to prevent black cockroaches from entering the apartment from ventilation pipes, it is recommended to use the sink and bathtub as often as possible.

Keeping water in the pipes will help significantly reduce the likelihood of insects entering the apartment. Otherwise, the methods on how to get rid of sewer cockroaches are the same. You can find out more about them below.

Basement

The most common places where black cockroaches accumulate are basements, where there are all favorable conditions for the growth of insect colonies, namely moisture and warmth. As for food, a black cockroach needs a small amount of food to live, and if there is none, the insect can easily exist without food for two or more months.

If there are cockroaches in the basement, various chemicals will help deal with them. Such, for example, as gels, crayons and powders . With their help, it is necessary to treat all the cracks through which insects can enter the apartment. In order not to create favorable conditions for black cockroaches at night, it is recommended to carefully monitor the cleanliness of the kitchen, as well as block the insects’ access to water.

Folk remedies for Prussians

Method No. 1

The most common folk method of getting rid of barbels is the use of baits made on the basis of boric acid. Prussians love to eat granulated sugar, liquid yeast, boiled egg yolk and mashed potatoes. Boric acid is combined with a tasty and aromatic bait, small balls are formed from the resulting mixture and placed wherever there are concentrations of mustachioed “invaders”.

Method No. 2

Cockroaches are cold-blooded creatures. Air temperatures below +5 C˚ cause insects to lose their ability to reproduce and ultimately die. Therefore, since ancient times, people have often resorted to “chilling out” their homes. This method is quite effective for getting rid of these unpleasant roommates. But in city conditions, its use is unlikely, since you can easily damage the heating system of not only your apartment, but also an entire multi-story residential building.

Method No. 3

Prussians hide in their shelters during the day, and at night they begin active movements throughout the entire apartment. Turning on the lighting in this situation is an absolutely meaningless measure, since cockroaches have no fear of it. They can only be frightened by the noise of approaching steps; upon hearing it, the Prussians immediately take to their heels.

Therefore, you can try to make a trap for Prussians yourself. You need to take a glass or enamel bowl and place a tasty bait on its bottom. Lubricate its edges using Vaseline or any fat. Trying to get to tasty food, the cockroach climbs inside the container, and it will never be able to climb back out. Insects caught in this way can be destroyed by pouring boiling water on top.

The configuration of the body of cockroaches gives them the opportunity to penetrate into cracks in walls, inside furniture, under wallpaper and under baseboards. Only a vacuum cleaner will help remove the Prussians from these hiding places. However, keep in mind that the Prussians do not die inside the dust collector.

Ways to control cockroaches

The appearance of pests is not always associated with unsanitary conditions in the room; they also settle in a clean kitchen. It is enough for them to have access to water; almost any organic matter serves as food for insects. The fight against parasites is carried out comprehensively, using physical and chemical methods. An effective option is to freeze the room; cockroaches die at sub-zero temperatures. But this is a seasonal method and is not suitable for everyone. Available physical methods are mechanical destruction and installation of glue traps.

Many chemicals have been developed to get rid of pests. They are available in the form of dusts, gels, pencils, and sprays. The use of Raptor and Raid aerosols gives a quick effect. Insecticides are sprayed into the nest, a place where insects gather. Preparations in the form of gels and dusts are also applied along the routes of pest movement. If the colony size is small, it is enough to spread out poisoned baits. They are prepared from egg yolk and boric acid.

As preventive measures, it is recommended to get rid of all water leaks and have no access to food. Products are stored in plastic or glass containers with a lid. Compliance with sanitary standards and cleanliness is the main preventive measure.
