Even after professional treatment, one might sometimes notice that cockroaches reappear in the house. This causes understandable concern, as cockroach disinfection requires expense and time. In fact, the reappearance of insects does not always mean poor-quality treatment — the reasons can vary, and it is important to understand them to prevent new infestations. It is the right cockroach remedy and a comprehensive approach to control that help achieve a lasting result.
Main reasons for the reappearance of cockroaches
Often, the source of the problem is not the treatment itself, but the conditions that continue to attract pests. Even the most effective product may not yield a long-term result if the cockroaches have somewhere to hide and something to eat. In some cases, they return after a few days, having used secluded spots or adjacent premises.
The main reasons for re-infestation include:
- Presence of gaps, cracks, and other entry points from neighboring apartments or stairwells;
- Leftover food and water, providing insects with nourishment and moisture;
- Untimely cleaning and improper food storage;
- Use of unsuitable or expired preparations;
- Missing certain areas during pest control.
Furthermore, cockroach pest control loses effectiveness if the factors attracting them to the premises are not eliminated. Cockroaches quickly adapt and can develop resistance to certain substances.
Main routes of re-infestation
Even after cockroach extermination in Tashkent has been successfully carried out, new individuals can re-enter the house. They are capable of moving through ventilation shafts, cracks, through pipes, and even with household items brought from other premises.
Cockroaches often settle in places with access to moisture and food scraps. Kitchens, basements, and bathrooms are especially dangerous, where the insect can find water and shelter. In such cases, regular cleaning and thorough checking of hard-to-reach areas help.
Typical routes of re-infestation include:
- Transfer with belongings, household appliances, or boxes;
- Penetration through gaps in the floor, under baseboards, and around pipes;
- Proximity to untreated apartments;
- Entry of insect eggs resistant to chemical effects.
Mistakes in self-extermination of cockroaches
Attempts to do everything by oneself often lead to the opposite effect. People use an unsuitable product or incorrectly calculate the dosage. Often, instead of a professional insecticide, they use improvised mixtures, such as boric powder or boric acid, whose effectiveness decreases with improper application.
Even a good cockroach gel or syringe must be used strictly according to the instructions. An excessive dose can repel insects without killing them. Using several preparations simultaneously, which weakens the effect of each, is also a mistake. Furthermore, some insects may survive and return after the cockroach poison stops working.
How to avoid the return of insects
For pest control to yield results, it is important not only to carry out the treatment but also to ensure the conditions required for long-term cockroach protection. First and foremost, all conditions conducive to their appearance must be eliminated: cut off access to water, seal gaps and holes, clean regularly, and store food in closed containers.
For prevention, traps, ultrasonic repellers, and special long-acting preparations can be used. It is important to know exactly where their accumulation point is — in furniture cracks, under the stove, or in the basement. Only this way can the complete destruction of the colony be achieved.
If self-help actions have not worked, it is worth contacting specialists who will conduct a professional inspection and select an effective method for repeat treatment. If necessary, you can order cockroach extermination and find out which cockroach pest control price is most suitable for your premises. And when choosing household treatment, it is important to buy a cockroach remedy from a verified manufacturer to avoid counterfeits and maintain the safety of the dwelling.
