The appearance of cockroaches in the home causes dissatisfaction. Walking into the kitchen and finding even one cockroach becomes an extremely unpleasant event.
Once cockroaches are discovered, it is important to immediately take measures to destroy them. If you miss this time window, the number of insects in the apartment will quickly increase, and it will become almost impossible to cope with them on your own.

Cockroach: what kind of pest

These insects belong to the order cockroaches, and all species of this pest are similar to each other in structure, lifestyle and behavior.

Characteristics of cockroach anatomy include:
1. A flat oval body with a chitinous cover, the color of which may vary depending on the species.
2. Antennae on the head, which are used to exchange signals between individuals, as well as as organs of touch and smell.
3. Round eyes, capable of seeing in any direction, although in some species the vision function may be atrophied.
4. Three pairs of legs with spikes, providing cockroaches with excellent grip on the surface, fast running and instant change of direction.
5. Powerful oral apparatus with jaws covered with chitinous teeth, which allows cockroaches to gnaw and digest almost any solid food, including wood.
6. Many respiratory openings and nerve nodes throughout the body, which makes it possible for an individual headless individual to survive for up to 9 days before dying due to lack of food and water.
7. Thin wings with a mesh pattern and strong elytra, while the ability to fly is not inherent in all, but only in some individuals.
8. Segmented abdomen, consisting of 8-10 parts.

Cockroaches have a high degree of survival, are able to go without food for a long time and adapt to various chemicals. This should be taken into account when fighting these insects on your own.

Life cycle and behavioral characteristics of a cockroach

Common red cockroaches, or cockroaches, reproduce at a high rate. The female carries a special capsule called an ooteca on her abdomen or even inside her body (in the case of viviparous species). One ootheca can contain up to 30 eggs at a time. Under favorable conditions for the development and reproduction of these insects, the population can increase hundreds of times per year.

The complete development cycle of the pest is as follows:

  1. Egg: A cockroach egg is a microscopic milky-white capsule up to 1 mm long. One embryo develops in each egg, and their vulnerability is compensated by the dense ootheca shell. The duration of the egg stage depends on the type of cockroach.
  2. Nymph: The larva of a cockroach, initially white and structurally similar to adults. With each molt (there are 6 in total), the nymph darkens and increases in size. In the red cockroach, the nymph stage does not exceed 4 weeks, while in the black species it can last several years.
  3. Imago: An adult insect. After an individual reaches sexual maturity, its appearance no longer changes, and the insects are ready to reproduce.

The lifespan of cockroaches depends on the species and external conditions. In unfavorable conditions, their development slows down. For example, extremely low temperatures, low humidity, and lack of access to food and water are considered unfavorable conditions.

In the absence of regular food, a cockroach can live up to 30 days. Their powerful jaws and additional jaws in their stomach allow them to consume a variety of materials, including paper, cardboard, glue, leather, wood products, and even chew wiring. In case of food shortage, cannibalism among cockroaches is not uncommon. Rare cases of aggression are even directed at humans.

What cockroaches can we find in an apartment?

There are more than 7000 species of cockroaches in nature, but we can only find three of them in Russian apartments.

The main types of pests that we may encounter at home:

  1. Red cockroaches (Prussians): This type is perhaps the most common. The reproductive efficiency of Prussians is very high, and the larva quickly turns into an adult. The body length of an adult pest does not exceed 1,5 cm. It is noteworthy that in favorable conditions the Prussian can live up to a year.
  2. Black cockroaches: This species is less common in domestic environments due to the long developmental stage of the nymph. People often manage to destroy black cockroaches before they begin to actively reproduce. This subspecies stands out for its large size, reaching 3 cm. The black shade of the chitinous cover helps the cockroach effectively camouflage itself in dark corners.
  3. American cockroaches: Imported from Central and South America, they are practically never found in residential buildings. This species is particularly large in size; the length of the body including wings can reach 8 cm.

It is important to emphasize that despite the differences between these species, the methods of combating them are almost identical. The main rule is to start pest control as early as possible.

How cockroaches can get into an apartment

It is generally accepted in society that cockroaches appear in dirty apartments where unsanitary conditions reign. However, the reasons for the appearance of these pests in the home are much more varied. Even if you clean regularly, sooner or later you may find them in the kitchen.

Possible ways for cockroaches to enter an apartment include:

  1. From the street: Pests can get inside through even unnoticeable cracks in the walls.
  2. Through ventilation, sewerage, cracks in ceilings and floors: Insects can enter from neighboring apartments due to too high a population, lack of space and food, and the pest control process of neighbors. If you find out that your neighbors are carrying out cockroach control, you should take protective measures.
  3. From the basements: Basements create ideal living conditions for pests - humidity, darkness and the presence of food. This is the most common route for parasites to invade residential premises, with residents on the first floors especially at risk of infection.
  4. Unsuccessful purchases: Larvae or adults can enter your home on food, clothing, furniture and other goods. Inspect used items carefully, especially when purchasing used items, to avoid any unpleasant surprises.

Understanding how cockroaches enter your home is important for taking steps to prevent infestations. However, if pests do appear, it is necessary to take immediate action; it is advisable to carry out disinfestation at the same time as the neighbors.

Why are cockroaches dangerous for humans?

The problem with cockroaches in an apartment is not limited to just their visual nuisance. There are much more serious reasons why it is important to get rid of these insects as soon as possible.

The harm from the presence of cockroaches can be enormous for humans:

  1. Spread of dirt and bacteria: Before getting into an apartment, cockroaches often run around in unsightly places such as garbage chutes, sewers and street garbage dumps. They carry all these germs and bacteria on their paws into your home, leaving them on food, personal care items and other surfaces.
  2. Spread of infections: Cockroaches can serve as carriers of various infections, such as intestinal infections and salmonellosis, and also carry helminth eggs.
  3. Damage to property: Even with careful hygienic care, cockroaches can find food in your home, using their developed jaw apparatus to eat books, leather goods, wooden objects, wallpaper and glue.
  4. Damage to machinery and electrical equipment: Cockroaches can chew through wiring, create nests in household appliances and sockets, and also clog the drain hoses of washing machines and dishwashers, which increases the risk of breakdowns and even fire.
  5. Attacks on people: In situations of acute food shortage, cockroaches can attack sleeping people, gnawing eyelashes, eyelids and lips.
  6. Allergic reactions: Cockroach nymphs leave chitinous shells after molting, which can cause allergies and lead to asthmatic attacks.

This list of negative consequences only emphasizes the importance of getting rid of cockroaches as quickly as possible. This will not only preserve your property and food, but will also protect your health.

How to get rid of cockroaches yourself

There are a variety of do-it-yourself cockroach control methods that vary in availability, effectiveness, and purpose.

The main groups of funds include:

  1. Folk recipes.
  2. Boric acid. (Powder is available in pharmacies).
  3. Chemical household insecticidal preparations.
  4. Traps of various types.
  5. Ultrasonic repellers.

Some of these methods are effective as cockroach killers, while others may be more suitable for permanent results and prevention. Based on our experience, the best results are achieved when using several methods together.

Traditional methods of fighting cockroaches

Traditional methods of fighting cockroaches are mostly based on the use of strong odors that repel these parasites.

Here are some effective options based on this principle:

  1. Ammonia and vinegar: Strong odors that repel cockroaches. A few drops of ammonia or vinegar can be added to the water when cleaning to wipe floors and other surfaces. You can also spray the room with a solution from a spray bottle.
  2. Kerosene: This product not only has a pungent odor, but also has a destructive effect. Kerosene can be used to lubricate baseboards, the area around sewer pipes and trash cans.
  3. Essential oils: Essential oils from plants such as mint, tea tree, wormwood and others can be purchased at the pharmacy and added to the water when cleaning. They can also be used in an aroma lamp.
  4. Scented plants: Mint, lemon balm, chamomile, wormwood and other plants with a strong aroma. Bouquets of fresh or dried herbs can be placed in the room or kitchen. You can also use ground dry plants in a sachet.

Traditional methods are good as preventive measures, especially if there is information that neighbors are currently struggling with parasites. They can also be useful in reinforcing the results of chemical treatments, since the main effect is to repel rather than kill pests.

Boric acid against cockroaches

Boric acid powder is available over the counter and is highly effective in destroying the digestive system of parasites, causing them to become dehydrated. There are a number of recipes that include boric acid to kill various pests.

Here are a few of them:

  1. With egg: Mix 20 grams of powder with one boiled yolk, add sugar or vanillin to attract the pest. The resulting sticky mass is rolled into lumps and distributed among the habitats of the parasites.
  2. With sugar or honey: Dilute 50 grams of powder in 100 ml of water, then add a spoonful of sugar or honey. The resulting liquid is poured into saucers and placed in sinks and bathtubs overnight.
  3. With sunflower or sesame oil: Various recipes mix the oil with boric acid, such as egg yolk. The fragrant oil attracts the pest.
  4. Balloons: Boric acid is mixed with flour, starch, powdered sugar, vanillin, then placed in a bowl. The wet mass is formed into small balls and distributed throughout the house.

These boric acid methods are effective in the early stages of home infestation. However, if the pest population has already grown, more serious and effective action may be required.


Household goods stores offer a wide range of household insecticides in various forms. The main effect of most of these drugs is aimed at the nervous system of pests, causing their paralysis.

Insecticides are available in the following forms:

  1. Aerosols;
  2. Gels;
  3. Crayons.

All chemical household insecticides are effective and easy to use. However, it should be remembered that cockroaches have the ability to adapt to chemicals. Therefore, it is recommended to avoid reusing the same insecticide more than twice.

Insect traps

You can purchase ready-made glue traps, or you can easily make a simple design yourself. Sugar or bread balls are placed in each trap as bait. Adhesive strips are placed on the inner sides of the traps. When insects try to reach the bait, they stick to the glue and become motionless. Without access to food and water, they quickly die.

It is recommended to place traps in a ratio of 2-3 structures per 10 square meters. This is not only a convenient indicator of the degree of infection of a room, but also an excellent method of getting rid of those insects that were able to survive after the use of insecticides. Sticky traps are set overnight, then checked in the morning and any insects caught are disposed of.

Ultrasonic repellers

Another simple and inexpensive method of getting rid of cockroaches. It is effective, especially when the number of insects in the room is still small or after chemical treatment to prevent their reappearance.

Ultrasonic waves used for pest control have similar characteristics to the alarm signals that insects transmit to each other. When they perceive such a signal, they strive to leave the space as quickly as possible.

Prevention and preparation of the apartment for treatment

As mentioned earlier, it is preferable to use several methods at the same time. The main and most effective means are chemical insecticides. Intensely scented plants, essential oils, and traps can serve as effective complementary methods to enhance results and prevent re-infestation.

The purpose of treating an apartment is to poison insects. However, without cutting off access to food and water, insecticides may not be effective. Therefore, preliminary preparation plays an important role.

Main stages of preparation for processing:

  1. Thoroughly clean and organize the kitchen. Remove all crumbs from tables, shelves and floors, and place food in tightly sealed containers in the refrigerator.
  2. Wash countertops, shelves, appliances and floors. Pay special attention to cleaning surfaces around the stove and sink.
  3. Check pipes and plumbing for leaks and repair them if found.
  4. Get rid of any water sources such as pet water bowls (they should be put away at night) and avoid pooling water in the trays of potted plants.
  5. Wipe the sink, sink and bathtub dry.
  6. Take out the trash and cover the bin with a tight lid.

General preparatory cleaning is recommended to be carried out the day before the scheduled treatment. Apply the poisonous gel overnight along baseboards, around trash cans, and in other possible hiding places for cockroaches.

What to do after treatment with chemical insecticides

The gel, left overnight, has already managed to significantly reduce the number of parasites. To increase effectiveness, it is recommended to treat with aerosols or liquid insecticides in the morning.

Use the selected product in accordance with the manufacturer's instructions. During treatment, carefully close all windows and doors, first removing children and pets from the house.

After completing the treatment of the apartment, it is recommended to leave the premises for several hours. Upon return, ventilate all rooms, remove dead insects and dispose of them by flushing them down the drain.

Clean the floors (you can use a vinegar or ammonia solution for this), avoiding areas along the baseboards. It is also necessary to remove any remaining product from contact surfaces such as switches, door handles, etc.

How to avoid re-infection

Through the comprehensive approach described above, you can effectively deal with cockroaches. However, it is important to consolidate the achieved result and take measures to prevent the reappearance of insects in the apartment.

Here's what to do and consider:

  1. Use folk remedies or ultrasonic repellers to scare away new individuals, and also set traps in places where pests are believed to live.
  2. Postpone general cleaning at least a month after treatment with insecticides, given that many drugs have a prolonged effect.
  3. Do not leave food on the table, carefully remove crumbs and wash dishes immediately after use.
  4. Be vigilant for leaks.
  5. Keep your floors clean by adding vinegar or ammonia to your floor cleaning water.
  6. Seal all cracks and cracks, install mosquito nets on the windows.
  7. Check your purchases carefully and avoid buying goods secondhand.
  8. If necessary, re-process. If the cockroaches persist, call a professional pest controller for help.

Following these measures will help you get rid of the problem once and for all.
