What are sewer cockroaches and how to get rid of them

What do sewer cockroaches look like and how to deal with them?

Insects, including cockroaches, tend to be a problem in many older buildings. Although it is unusual, it is not uncommon to see cockroaches coming out of gutters, especially in older buildings. It is known that, at the moment when targeted baiting of insects begins in some place, detecting pesticides, cockroaches try to escape from the poisoning zone in any possible way, including from drains.

Cockroaches can hold their breath for 40 minutes. This allows them to move from house to house through sewer systems. By the way, before you flush cockroaches down the toilet, remember this fact. Flushing a cockroach will not kill it.

These insects quickly develop immunity to many of the insecticides that have been used to kill them for years. Cockroaches are apparently smart enough to detect pesticides and find ways to avoid them. The sewers are a great way to escape and migrate to new safe areas.

From the point of view of cockroaches, the sewer is an ideal home. They thrive in the damp darkness, feeding on decaying organic matter and countless refuse. The underground sewer system is a real resort for them: warm in winter and cool in summer. Sewers provide protection from people and predators (with the possible exception of hungry rats). There is plenty of water here, and their lunch takes place in a 24-hour restaurant with a self-assembled tablecloth of delicious human waste.

How to fight?

To get rid of these pests, you should use the entire arsenal of modern insecticides. Some drugs will be needed to cut off cockroaches’ access to food and water, while others will be needed to completely destroy the population. If you want to get rid of cockroaches forever, it is better to start the fight together with your neighbors in the stairwell.

One of the most important rules is to follow through. If the number of cockroaches decreases, it is important not to stop and continue treatment. Otherwise, their population may completely recover within a week. You need to remember that in addition to live cockroaches, there is also a nest with eggs. In the case of sewer insects, it can be located outside the apartment and is almost impossible to detect.

The most reliable method to get rid of cockroaches is to call an exterminator. Especially if the treatment is carried out throughout the house. To fight on your own, you will have to use the entire arsenal of available means.

Medicines to control cockroaches

First on the list are contact insecticides. They will not help get rid of insects, but they can block their path to food and water. The most well-known drugs in this group are gels and pastes of the Kombat and Dohlox brands. They must be applied in continuous lines to floors and walls. Using the paste, you can fence off the kitchen, preventing pests from getting to your food. If finances allow, then gels and pastes can be distributed behind baseboards, in cracks, and at tile joints in the bathroom. The gel must be applied at once, in all rooms at once. Particular attention should be paid to those places where cockroaches appear most often.

Another remedy that will help stop the spread of cockroaches is powders. The most famous brands are Regent and Phenaxin. You need to prepare the mixture according to the instructions and sprinkle the same areas that are treated with gel or paste. It is important to remember that gels, pastes and powders are an addition to aerosols, and they will not help get rid of insects, but will only stop their reproduction and spread. The same goes for traps.

An effective remedy

What will help get rid of insects? Aerosol insecticides that allow you to quickly treat all surfaces. Modern drugs use high doses of toxic substances, which, despite their effectiveness, are safe for humans. There are more than a dozen popular and inexpensive products. You should choose among them based on your own preferences.

The aerosol must be used according to the instructions. It is likely that you will not be able to get rid of insects in one spray, especially if the nest is not located in the apartment. It is necessary to use the drug until the insects disappear completely.

Why are black cockroaches dangerous?

Among the reasons why black cockroaches are considered dangerous is their feeding habits.

Cockroaches eat dead skin, dead animal meat, and spoiled food. Because they defecate inside homes and even food service establishments, they can transmit any kind of infection. Cockroaches can even leave their feces directly on food, which you can then eat. If food is contaminated with cockroaches and is subsequently consumed by a person, food poisoning can occur. Symptoms that this has happened to you include abdominal pain, nausea and vomiting.

Cockroaches can also transmit other diseases through their droppings. Serious diseases associated with cockroaches from cross-infection include typhoid fever, dysentery, leprosy and cholera.

Staphylococcal and streptococcal infections

There are many types of bacteria that cockroaches carry. While most bacteria are harmless, there are some that can lead to serious infections. For example, Staphylococcus aureus can cause boils in people, as well as serious infections of the lungs and heart. Streptococcal infections can also result from direct or indirect contact with cockroaches.

Allergies and asthma

Of all the pests that live indoors, cockroaches are the most dangerous for allergy sufferers. Trouble can come from allergens found not only in the saliva of cockroaches, but also in their shed skins and feces. Signs of an allergy include itchy, watery and irritated eyes and frequent sneezing. A rash may appear on your skin if you are allergic to cockroaches.

Asthma attacks are more common in families living in areas infested with cockroaches. During an asthma attack, a person begins to cough, feel tightness in the throat and chest, and has difficulty breathing. The severity of symptoms will vary from person to person, and in some cases, asthma attacks can be life-threatening.

Research shows that cockroaches are a leading cause of asthma and allergies! In some cities, up to 45% of children are allergic to cockroaches. Many children develop asthma due to exposure to cockroaches.

Cockroaches in an apartment: where do they come from and why do they reproduce?

Cockroaches as neighbors are a very unpleasant phenomenon. The discomfort they cause with their appearance is not the worst thing. Insects are carriers of various viruses and diseases that pose a danger to humans. Therefore, you need to try not only to drive them out at the first appearance, but also to prevent further reproduction.

First, you should try to find out where the uninvited guests came to you from. If they have moved from neighboring apartments, then it will be impossible to eradicate them forever only within the confines of your home.

In this case, you need to take joint action with your neighbors, poison cockroaches simultaneously in all neighboring apartments, and ideally in the entire house, in order to completely eliminate them.

If the source of infection was the street, and you brought large cockroaches along with some box or things, it is advisable to treat all the rooms and the entire local area.

A cockroach can get into an apartment with purchases from a store , and with things brought from a tourist trip, and even arrive in a parcel.

Most often, red cockroaches breed in houses, but you can also find black and albinos. Even one specimen accidentally brought into the house can lead to the fact that after some time the population grows to incredible numbers. Their life cycle is such that the population is capable of increasing exponentially.

The following conditions contribute to the reproduction of cockroaches:

Constant access to food sources .
Dirty dishes, a bucket full of waste, leftover food on the stove - all this serves as food for cockroaches. Moreover, they begin to actively feed at night, therefore, the habit of leaving a dirty kitchen at night contributes to their excellent health.
Access to water .
The only thing “Stasiks” cannot do without for long is water. All sources of liquid in the house must be shut off. Leaking taps, condensation in the bathroom, even water from watering flowers can become a source of drinking for insects. Therefore, your task is to dry all items as much as possible so that the cockroaches have nothing to drink.
Favorable temperature .
Apartments have many secluded corners in which insects feel comfortable. At the same time, they can enter the house through cracks, ventilation, and pipes. That is why it is important to carefully seal all the cracks in the apartment - under the baseboards and in other places, and cover the ventilation holes with a fine mesh.

Where do black cockroaches come from?

Although cockroaches love to take up residence in various types of buildings, both new and old, many often begin their lives outdoors. When it gets too cold or too hot outside, they start looking for a new home. Instead of directly invading your apartment, they often end up in the drain first, which is usually warm and dark. Sewers provide the food and water insects need to survive and also provide protection from the elements.

Cockroaches are explorers and soon begin crawling up dry drainpipes, laying eggs along the way. As the larvae hatch, they continue to crawl up and out of drains, often ending up in dark closets, trash rooms, basements, etc.

Finding cockroaches in the basement or coming out of the sewer usually indicates:

They found ways to invade the building from the outside.
They are hungry and looking for food.
If you see one cockroach, there are many others that will soon be crawling onto your territory.
You should expect sewer odors to follow the arrival of cockroaches.

The presence of cockroaches in the sewer system would not be a problem if they remained in place. But they don't. Adult nymphs tend to migrate in search of food and new places where they can raise a new population. They can simply leave the sewer, pushing out ventilation dampers, and enter buildings.

Sewer roaches can also enter buildings when the main sewer line is backed up, dumping thousands of roaches. Heavy rains can push cockroaches out of combined sewers and into basements. Or the drain trap may dry out and the roaches may simply walk through the drain pipes, through the trap, and out of the floor drain.

When cockroaches occupy sewer systems and, more importantly, emerge from them, solving the problem is not as easy as you think. The older the sewer system, the more likely it will be infested with cockroaches and rats, and the more difficult the problem will be to solve.

Drain under the sink

Plum trees provide a good, cool, quiet place to breed, eat food, and hide for protection.

Prevent sewer roaches from getting into your kitchen and bathrooms by making sure sinks are used regularly.

The pipes below the drain have a U-shaped loop called a “trap.” If the bathroom is not used, all the water in the "trap" dries up and sewer roaches enter your home.

When drains are used regularly, water remains at the bottom of the U-shaped pipe, preventing the water from draining completely. This “trapped” water blocks sewer roaches from coming through the drain and into your home.

If you are not a professional plumber, you will have to study the design of your home sewer system from photos. This is essential if you have a problem with sewer invaders.

Harm to humans

As stated above, cockroaches transmit diseases because they carry pathogenic microorganisms in their bodies that can be transmitted to us, and cause diseases such as suffocation, tuberculosis, cholera, leprosy, dysentery, typhoid fever and more than 40 other pathogenic bacteria and viruses.

Cockroaches are crawling out of the basement

Preventive measures do not always help. Sometimes there are so many cockroaches in the basement that they enter the apartments by any means. In some cases, the cause is an ill-organized protective barrier or an ineffective insecticide. What to do if cockroaches crawl out of the basement?

To combat Prussians, mechanical and chemical methods are used. The first group of methods is the use of glue traps and other similar devices. With their help you can get rid of single individuals.

Household insecticides, the effectiveness of traditional methods

If the population of cockroaches in an apartment reaches an alarming scale, household or professional insecticides will help to remove the pests. The store offers a wide selection of chemical preparations against synanthropic insects. To treat small holes, cracks, and space under the baseboard, it is better to choose a product in the form of an aerosol. The remaining routes of movement and habitat of cockroaches can be treated with an insecticidal preparation in the form of a gel, spray, chalk, or powder.

Methods of professional control of cockroaches

Professional treatment of an apartment using the fog method by sanitary service employees is an effective way to get rid of any number of cockroaches. Experienced experts will analyze the situation and develop an optimal strategy for exterminating synanthropic insects. The use of modern disinfestation equipment allows you to thoroughly treat all surfaces and hard-to-reach spaces of the apartment in a few hours. If necessary, experts will talk about preventive measures and organizing a protective barrier against the reappearance of cockroaches.

Preparing the room for processing

The effectiveness of professional treatment is significantly influenced by the quality of preparation of the premises for disinfestation.
The apartment must be wet cleaned, garbage and unnecessary rubbish must be taken out, furniture must be moved away from the walls, and specialists must have free access to all corners. Even a small amount of dust on the surface reduces the effectiveness of the chemical several times. Depending on the method of disinfestation, the strategy of action after the event changes. If an insecticide with a prolonged action is used to kill cockroaches, after returning to the apartment, door handles, bathroom fixtures, countertops and other surfaces that household members touch most often are wet treated with detergents. In corners, behind the refrigerator and stove, under cabinets and baseboards, cleaning is carried out only after 1.5-2 weeks, when the insecticide destroys all or the vast majority of synanthropic pests.

Prices for treating cockroaches in a basement in Moscow

SES "Des Group" offers services for disinfestation of residential and non-residential premises. The company cooperates with individuals and legal entities. It is possible to conclude a long-term contract or an agreement for one-time provision of services.

Scope of work	Method	Processing cost
Studio apartment	Cold Fog / Hot Fog / Barrier Protection	From 1500 ₽
Two-roomed flat	Cold Fog / Hot Fog / Barrier Protection	From 2100 ₽
Three bedroom apartment	Cold Fog / Hot Fog / Barrier Protection	From 2300 ₽
Legal entities	Cold fog / Hot fog / Barrier protection / Required package of documents	From 9 ₽\m2
Kitchen/bathroom/hallway	Cold Fog / Hot Fog / Barrier Protection	From 900 ₽

To treat basements and other premises, the Dez Group sanitary service uses a fog generator and a certified insecticidal preparation with proven effectiveness.

How the fog generator works

The working solution is poured into the equipment container. With the help of a pump, the chemical flies out of the generator nozzle under pressure in the form of fine droplets. They have a diameter of less than 80 microns. Particles easily penetrate into all corners, cracks and crevices, and settle on walls, ceilings and other surfaces. In a few hours, without much effort, every square centimeter of the basement receives its portion of the insecticidal preparation. An additional effect is provided by the prolonged action of the solution. The insecticide continues to kill synanthropic insects for a long time after treating the basement.

The official guarantee of the result is enshrined in the contract. If necessary, employees of the Dez Group sanitary service will organize repeated disinfestation. If you have any questions or want to discuss the details of cooperation, leave a request on the company’s website. A SES representative will contact you in a few minutes.

How to block cockroaches from entering your home

Cockroaches often live in bathrooms and kitchens where they have a good source of water and food.

If you find cockroaches in your drains, follow these steps:

Seal your drain pipes. Use a flashlight to find any cracks or holes in your drain pipes. If you find any cracks or holes, seal them with an appropriate sealant.
Repair leaking faucets. Standing water attracts cockroaches.
Seal cracks and holes around drain pipes. You can use duct tape to quickly repair cracks and cracks. For a more permanent solution, use silicone caulk, plaster or cement.
Look for gaps around the pipes under the sink. Fill these gaps with silicone caulk or polyurethane foam. You can fill large holes with steel wool or copper mesh before sealing them.
Fix holes in your walls. Use expanding foam insulation to seal any spaces around pipes where they pass through walls.
Stop condensation. Wrap insulation tape around any pipes that produce condensation. When you remove the water source, the cockroaches will go elsewhere to get water.

Cockroaches can enter premises in other ways. They can enter from open areas, especially garbage containers and related businesses that have poor sanitation; they can be introduced into the home unknowingly through packaging and containers.

How to identify a sewer cockroach?

Firstly, these cockroaches only appear at night. They are predominantly nocturnal and go out in search of food in the dark. Sewer cockroaches are dark brown or black in color, much darker than regular cockroaches. In size, they are larger than indoor ones. Another distinctive feature is the chitinous shell that hangs down the sides of the elongated body. They grow up to 3 cm.

When they find themselves in an apartment, they prefer to hide in hard-to-reach, damp places: around the toilet, under pipes, near radiators. They are most often seen in the toilet, bathroom and kitchen.

Why are they dangerous?

Cockroaches that live in sewers and come into contact with waste products are much more dangerous than ordinary apartment roaches. They carry many unpleasant diseases. The least you can get is dysentery. In addition to it, cockroaches can carry various bacterial infections and worms. If insects get to food, there is a very high chance of getting an infectious disease.

How to Help Prevent Cockroaches from Getting into Your Drains

Move or remove trash cans. Garbage cans under the sink or bathtub can attract cockroaches.
Cover drains with a stopper at night. You can use rubber drain caps or metal drain screens. Cockroaches are nocturnal, so it is important to block their migrations at night.
Clean kitchen drain. Pour cleaner into the kitchen sink to remove food particles that attract cockroaches.
Keep meters and appliances clean. Avoid leaving food on counters or in the kitchen sink, especially overnight.

Home protection against insects

Realizing that insecticides no longer deter many cockroaches and other insects, it is safest to call a pest control company as a first step. A pest control professional can help determine the type of cockroach infestation, check how cockroaches are getting into a building, and suggest ways to eliminate them.

Non-chemical methods of cockroach control

Like most pests, sewer cockroaches need three things: food, water and shelter. If you can eliminate just one of these things through proper sanitation, the cockroach population will be forced to die or move elsewhere.

Avoid old boxes and stacks of papers where cockroaches can hide.
Use a garbage can or bin with a tight-fitting lid and store trash in a sealed plastic bag overnight.
Eliminate leaky drains and taps; Cockroaches can only live on water.
Clean kitchen appliances thoroughly
Wash pet bowls overnight or place them in a plastic bag.
Vacuum regularly and limit food consumption to one room of the house. This will help prevent the pests from spreading to other areas such as bedrooms.
Seal and repair holes around doors, windows, plumbing pipes and baseboards.
Place mesh screens over windows, floor drains and vents.

Insect repellent gel

We recommend applying gels to all visible cracks and crevices, including under, behind and next to appliances, behind outlets, along pipe clamps, inside wall voids and on top of kitchen cabinets near the ceiling.

Continue to apply the gel every 4-6 weeks for up to 6 months, or until all signs of infection have resolved.

Powders

Using a hand rag and following label directions, apply the powder to areas where cockroaches hang out—under and behind baseboards, behind wall outlets, in wall voids, in cabinets and cupboards, and under appliances such as washers and dryers.

Aerosols

Contact sprays kill cockroaches immediately on contact and can also be used to flush cockroaches out of suspected hiding places. Most aerosols contain a chemical used to destroy and impede the life cycle of insects in their egg and larval stages. The idea is that if an insect cannot reach maturity, it cannot reproduce. Any form of “birth control” for cockroaches and other pests helps keep populations under control, preventing current and future infestations.

Insect traps

Traps are actually effective for cockroaches, but if you need to spray other pests, be sure to keep baits and sprays in separate areas so they don't interfere with each other.

Fighting methods

Black cockroaches have a cautious behavior. Often, traps designed for common red locusts are ineffective at controlling these insects because they avoid spilled powder or chalk paths.

To completely eliminate large black parasites, it is recommended to call professional exterminators. If this measure is not possible for some reason, you can pay attention to the methods presented below.

Mechanical destruction

The emergency and at the same time the most common method of fighting insects is mechanical, that is, it involves the use of a folded fly swatter or an ordinary house slipper. However, large cockroaches can easily survive even receiving a fairly significant blow, which is due to the presence of strong chitinous elytra.

In addition, even if a large number of parasites are exterminated, there is always a risk of repeated invasion - several cocoons with larvae, carefully laid aside by females, can simultaneously hide in secret corners. Therefore, to effectively get rid of colonies, it is recommended to choose a more reliable method.

Heat treatment

When black cockroaches appear in the bathroom, kitchen or any other room, it is best to use the safest, time-tested method, the essence of which involves heat treatment of the room.

To use this method, you need to completely freeze the room, that is, turn off the heating and leave the house for a while.

The significant disadvantages of this method are the following: you can get rid of black cockroaches in this way only in a private home and only in winter. If unpleasant guests appear in the apartment, you should choose another, more suitable method for this purpose.

Repellents

The easiest way to get rid of black cockroaches in an apartment is to use repellents - products that are not destructive to parasites, but help repel them.

This species directly does not tolerate the pronounced smell of bay leaves, elderberries, and flowering rye . To get rid of black cockroaches, it is recommended to make small bouquets from the above plants, and then place them in places where parasites accumulate.

The use of repellents is a fairly effective measure only when it is necessary to prevent the appearance of parasites. If the colonies have already taken a fancy to the apartment, it will not be possible to get rid of them by using aromatic plants.

Traps

Cockroach traps are quite effective. The only drawback of this method is the lack of harmful effects on insect larvae. Traps are only suitable for exterminating adult individuals.

According to the characteristics of the action, these devices can be as follows:

Traps with adhesive backing. Inside such devices there is a treat that attracts parasites. Once the insect gets inside, it can no longer get out. The obstacle can be a sticky base or a clever labyrinth.
Traps equipped with electrodes. When insects get inside, this type of device produces a weak electrical charge that kills or immobilizes the black cockroach. A trap with electrodes is equally effective against different types of cockroaches.
Contains an insecticide inside. The design of the trap is simple - inside there is bait containing a toxic substance. This remedy option is completely safe for pets. Some types of traps with insecticides are not aimed at keeping the cockroach inside; after eating the poisonous bait, the parasites go to their relatives, infecting them, thereby contributing to the death of the entire colony.

You can make a simplified version of the trap yourself . To do this, grease the inside of an ordinary glass jar with vegetable oil, and then place any delicacy inside. Leave the jar in a place accessible to cockroaches.

Mechanical methods

As previously written, "P", "J" or "U" style traps are found under almost all sinks, including floor drains. The purpose of these traps is to retain water, which helps prevent sewer odors from entering the building and blocks cockroaches from getting into sewer drains and sink drains. Maintaining sewer drains is an important task. The first step is to conduct a drain audit. Know the location of all drains in your home. Pay special attention to restroom floor drains.

Additionally, prevent cockroaches from moving through sewer pipes and dry floor drains by ensuring the floor is drained every week.

You can make sure your drain pipes don't dry out using the following steps:

Water: Pour a quart of cleaning solutions, bleach or other chemicals into all floor drains and less-used drains at least once a month. In hot, dry climates, you may need to do this weekly.
Prepare mineral oil. Apply a thin layer of vegetable oil or mineral oil down the drain to keep the water from evaporating for several weeks, possibly months. Repeat this every six weeks or every two months.
Drain trap control. You can install a controller on each water source. When the water evaporates, it releases a small amount of water down the drain to refill the drain.

These methods will not only keep drains and catch basins filled with water to help prevent cockroach incursions, but can also prevent sewer odors from entering restrooms and other areas of the facility. The release of sewer odors can be more than unpleasant, it can be dangerous if the odors contain toxic gases. Taking steps to maintain drains is another way you can stay healthy.

Mechanical and thermal methods

Treating the apartment with insecticides

Mechanical extermination is not the best way to completely remove cockroaches from an apartment. This method is effective only if you need to deal with several individuals; in case of a mass invasion, it does not give any results;
Freezing the house helps get all the Prussians out.
This method was practiced by our grandfathers. Its essence lies in the fact that the heating in the house is turned off, and the doors and windows are opened wide open in the winter. Freezing temperatures will force cockroaches to leave your home once and for all. Please note that insects may return from time to time if you do not use repellents after freezing; Cockroach trap (oil onion)
Means for repelling Prussians (repellents). We are talking about bay leaves, elderflowers, orange peel or fragrant pyrethrum (chamomile flowers). Repellents provide only a temporary effect, so they do not allow you to completely remove a huge colony of black locusts from your home;
Homemade traps. To build a simple trap for Prussians, you will need a deep glass container, oil and onion. Finely chop the onion and place it in a container with plenty of oil. Build a small bridge from paper or other available materials and place it over a container of oil. The trap works as follows: a cockroach climbs up a bridge and falls into the oil. The slippery surface does not allow the Prussian to escape from the trap, where he dies from suffocation;
Insecticides are the most powerful means for combating black prussians. The whole variety of chemicals can be divided into several groups: powders, gels, aerosols, crayons. Special means allow you to remove even a large colony of cockroaches.

We invite you to read: How to destroy cockroaches in an apartment forever with your own hands: how to eradicate them at home, how quickly you exterminated them

Cockroaches, ways to combat them

Ammonia is an aqueous 10% ammonia solution

Ammonia will help remove cockroaches from your home. Dilute 1 teaspoon of ammonia in a bucket of water and wash the floors. Insects will leave the room when they smell a strong odor. Note that cockroaches often return, so in the future the floor should be washed only with ammonia;
Kerosene, turpentine or denatured alcohol is used in emergency cases when your apartment is literally infested with insects.
Cover all baseboards and edges with linoleum and wait for the result. Cockroaches will leave your premises in a few days; Scope of application of boric acid
Geranium branches repel cockroaches. Note that the plant only scares away random insects, however, it does not completely get rid of black cockroaches;
Boric acid, boiled eggs and potatoes. Mix the prepared ingredients with boric acid and place them in places where cockroaches run out. Insects that taste the poisoned balls die after some time from dehydration;
Beer trap. Coat the walls of the old vessel with Vaseline, vegetable oil or glue. Pour some beer into a container and dissolve 1 sachet of boric acid in it. The effect is guaranteed - every morning you will collect dozens of bodies of drowned cockroaches and throw them in the trash.

The mechanical method of fighting involves the cold-blooded killing of every parasite seen with an improvised means. Make no mistake, despite the large size of the cockroach, it, like other members of its family, is fast and arrogant. Yes, if you manage to slam a couple at night, caught by surprise, know that crowds of their friends are now hiding in secluded places in the sewer.

You can scare off cockroaches with the help of strong odors - they are extremely sensitive to strong aromas. You can use the following recommendations:

Houseplant geranium. It is better not to place it in the bedroom - it can cause headaches. In other rooms, the flower will decorate the windows and repel cockroaches with its smell.
You can rub the floors with turpentine if they are not varnished. The smell will not irritate humans, but insects find it intolerable.
Sometimes vases with wormwood and bay leaves are placed around the house.
Dilute 1 tbsp in a bucket of water. l. ammonia. Then you should wash all the floors in the apartment. The cockroaches scatter, freeing the room.

Considering that cockroaches visit homes at night, many people use insect traps. To do this, take a jar, pour mayonnaise or beer into the bottom, and grease the inside walls with vegetable oil. In order for cockroaches to get into the jar, it is better to lean a ruler or rod against it. Cockroaches will climb inside, but will not be able to get out.

It is recommended to use the adhesive tape method. To do this, double-sided tape is attached to the cardboard, and food bait is left in the center. Cockroaches will seek food by sticking their paws to the tape. You can add boric acid to the bait for greater reliability.

Boric acid is a deadly poison for cockroaches. People and animals will not be harmed. A cockroach, touching this substance, will be paralyzed. This won't happen right away. Having reached its nest, it will come into contact with other individuals, poisoning the rest. This tool is very convenient for exterminating cockroaches whose home has become the sewer. They are not interested in boric acid itself. The effect will be if you add it to food bait.

Prevention

If you find sewer cockroaches, you need to take preventive measures to prevent food contamination, but this is not possible if the insects move freely around food storage areas. It is well known that biofilm that accumulates in drains contains harmful bacteria. Cockroaches that come from drains onto food contact surfaces can transmit these pathogens wherever they take up residence.

You need to do a thorough inspection, not just a step-by-step inspection, and then choose solutions to solve the problem and treat the insect infestation. Whether cockroaches come indoors through drains or collect in drains after they enter through other means, there are a number of solutions that can be used to eliminate cockroaches and make drains less attractive.

Such solutions include:

External procedures. Active perimeter pest control is required, including habitat reduction along the outer perimeter, a barrier spray on the foundation and around entry points, and a line of moisture-resistant granular bait applied beyond the spray barrier. Always read the label to determine which products can be used and where.
Drain cleaning. Cleaning drains by hand can be helpful, but be aware that scrubbing, steaming, and pressure washing can atomize pathogenic bacteria and potentially transfer them to food surfaces or processing.

Bio-sanitation products can effectively treat wastewater in environments with chronic moisture and high organic loads, and can also keep wastewater clean by digesting organic buildup that can harbor both pests and pathogens.

Keeping drains clean and using cleaning products can also provide further pest control. Regular use of any cleaning product is very important, as even those that do not kill insects will eliminate conditions conducive to insect breeding.

Drain procedures. Some pesticides can be used in and around drains, but some are strictly prohibited, so read labels before use. If there is any movement in the drain, especially if water is running, be careful with chemical use; make sure you are not contaminating groundwater or areas where water flows (such as into an open stream).
Drain traps. Traps in drain lines must be installed and operating properly to prevent cockroaches from entering drains and into the building through sewer or outdoor wastewater treatment plants. The sealing valve to catch water should allow water to flow out, but not allow insects to enter the room. Traps can also eliminate gases and odors that can come through drains and attract insects.
Internal inspections. Regular and thorough inspections of areas adjacent to drains will indicate whether the drainage program is effective. Cockroaches can hide in hard-to-reach places under and behind equipment, in stainless steel table legs, behind and under cracked tiles, and in wall voids that are accessible through plumbing and utility passages. Inspect these areas for cockroaches. If necessary, implement a site-wide bullying program as permitted by regulations.

0 Anton 02/26/2017 20:53 Unfortunately, such parasites are sometimes found in my apartment. Mostly at night they crawl out of their holes and run around everywhere. Personally, I fight them with the help of special Velcro and glue that I pour onto the surface. In the morning I often find pests in such traps. I don’t want to deal with chemicals; they affect human health, not just cockroaches.

0 Olga 03/10/2017 17:26 Yes, the fight against such cockroaches should be comprehensive, it is necessary to set traps for them, and it is advisable to periodically wash all corners, shelves, etc. with powder in order to wash away the trails that cockroaches leave behind, and of course perfect cleanliness in the kitchen, so that there are no crumbs or remnants of any food, since at night cockroaches are especially active and feed on what they find.
