Sometimes, even in a meticulously maintained home, some of the most unpleasant domestic pests—cockroaches—can "settle in." They multiply quickly, hide well, and are capable of surviving in difficult conditions; if the problem is not noticed in time, one or two individuals can turn into an entire colony. UNN will provide more details on why cockroaches appear and how to get rid of them forever.
Why cockroaches appear in an apartment and where they establish colonies
Everything cockroaches need for an "all-inclusive" stay is food, water, and warmth. That is why they most often settle in the kitchen or bathroom. It is important for them to have food crumbs, grease residue, trash, or moisture near the sink. Even a small amount of dirt behind the refrigerator or stove can become an ideal environment for a colony.
The peculiarity of these insects is that they are very resilient. If there is no ordinary food nearby, cockroaches can feed on dust, paper, glue, fabric, or even soap residue. This is why they are able to survive for a long time even in apartments that are regularly cleaned.
Most often, pests hide in dark and hard-to-reach places. They can be found behind kitchen cabinets, under the sink, near the trash can, in furniture crevices, behind household appliances, or even under wallpaper. Cockroaches also like to settle inside microwave ovens, toasters, televisions, and even computers, as electronics emit heat.
Another reason for their rapid spread is the ability of cockroaches to reproduce actively. If an apartment provides all the "amenities" for cockroaches, the colony will grow very quickly. Insect eggs are particularly dangerous, as they are difficult to notice during regular cleaning.
What are the first signs of cockroaches in the home
The first signs of cockroaches appearing can be black dots on furniture or dishes, an unpleasant odor, and the appearance of insects at night. Even if you see only one cockroach, it is a signal that an entire colony may be nearby. They often enter your home from neighbors through ventilation, pipes, or cracks in the walls.
What methods of fighting cockroaches can help
Boric acid
Boric acid remains one of the most famous remedies in the fight against cockroaches. It is used in powder form or added to baits with egg, potato, or sugar. Insects carry the substance on their legs or eat it along with the bait. After this, the acid affects the cockroaches' nervous system. The remedy is considered effective against adults but requires regular bait updates.
Ammonia and vinegar
Cockroaches are very sensitive to pungent odors. That is why ammonia or vinegar is often used as a deterrent. They are added to water when mopping floors and treating surfaces. Such smells create uncomfortable conditions for the insects, causing them to leave the premises. However, this method helps more to scare away pests than to completely destroy a colony.

Herbs and essential oils
Certain plants also help in the fight against cockroaches. Insects dislike the scents of bay leaf, mint, lavender, wormwood, geranium, and elderberry. Herbs are placed in areas where pests congregate, or essential oils are used to treat surfaces. Such remedies can reduce cockroach activity and serve as additional protection. At the same time, they are less effective if the colony is already large.
Chemical insecticides
The fastest results are usually provided by special chemical preparations. Stores sell sprays, gels, traps, and chalks against cockroaches. Most of them contain substances that affect the insects' nervous system. Such products help to quickly reduce the number of pests, but sometimes the treatment has to be repeated several times. Also, when using insecticides, it is important to strictly follow the instructions and avoid contact of children and animals with the preparations.
Homemade traps
If there are few cockroaches, simple traps can be used. A jar or a deep bowl with slippery walls is suitable for this. Bait, such as bread, cookies, or sugar, is placed inside. The insects crawl inside but can no longer get out. This method helps to partially control the number of cockroaches, although it usually does not solve the problem completely.
Freezing the premises
Cockroaches do not tolerate low temperatures well. In extreme cold, they stop reproducing and die. That is why in winter, the method of freezing the premises is sometimes used. For this, windows are opened for several hours or days so that the temperature drops significantly. However, this method is not suitable for all apartments and can be dangerous for pipes and household appliances.
The fight against cockroaches requires a comprehensive approach. Cleaning alone or just using traps is usually not enough. It is important not only to destroy the insects but also to remove the conditions in which they can reappear—moisture, food residue, and trash. The earlier the problem is noticed, the easier it will be to get rid of the unwanted neighbors.
