Cockroaches after disinfestation

4 minutes. for reading

Fighting insects presents many difficulties. Often people realize that it is not so easy to solve the problem on their own, and turn to professionals for help. However, an unpleasant situation arises: after disinfestation, insects not only do not disappear, but their numbers also increase. What could be the reason?

Many people underestimate the importance of re-processing. There is a common misconception that cockroaches or other pests can be killed instantly. Unfortunately, the reality differs from this mythical representation. You will find out further why insects are beginning to actively manifest themselves again.

Pest control is a complex process that requires a step-by-step and comprehensive approach. Experienced disinfectors are aware of how important it is to collect complete information about insects in a particular apartment. It is important to take into account all the details: appearance, possible quantity, causes of appearance, insect control agents used, and so on.

Cockroaches after treatment

Insect control is a challenging task. Not every treatment guarantees the complete disappearance of cockroaches, and the problem may reoccur. This is due to several factors:

  • Sanitary condition of the treatment area. If treatment is carried out in a polluted environment with debris, toxic residues and layers of dust, cockroaches may still find comfort in such conditions. Such situations are often associated with the incapacity of the owners, which creates difficulties in the fight against insects.
  • Impact of neighbors. Regardless of your desire to keep your home clean, the actions of your neighbors can also influence the appearance of cockroaches. Different ideas about cleanliness can lead to constant activity of insects in their homes, which makes it difficult to solve the problem.
  • Old house and the need for repeated treatments. In older homes, one treatment may not be sufficient. In such cases, the pest control process may need to be repeated several times to effectively eliminate the insects.
  • Ignoring the recommendations of disinfectants. Residents may ignore recommendations for caring for the premises after treatment. This involves thoroughly washing the insecticide off surfaces, which may result in renewed insect activity.

  • Carrying insects on your own. Insects often enter homes on their own through bags, packages or clothing, especially when people are outside the home. Solving this problem requires identifying and eliminating the source.

After disinsection, only adult individuals die, while cockroach eggs remain safe in the ootheca. One treatment may not be sufficient and repeated treatments are often necessary to completely resolve the problem. The appearance of “uninvited” guests after disinfestation may be due to the effects of chemicals on the insect body.

When insects die

Within three hours after disinfestation, the drug begins to show its effectiveness, affecting the body of insects and causing the death of adult insects. During this time, cockroaches can return to their habitat and transfer the active substance to their relatives, infecting them with deadly poison.

After five days, a significant decrease in population size is observed. The appearance of cockroaches in an apartment is becoming rare. Two weeks after disinfestation, complete elimination of all insects occurs.

This scenario is ideal provided that all stages of the sanitary service were carried out correctly by the staff.

How to make the pest control process more effective

Getting rid of cockroaches is not such an easy task. Despite the fact that the drugs used have an impact on their numbers, it is important to understand that your activity in preparation and subsequent actions after disinfestation is critical.

Preparation for disinfestation:

  • Ensure perfect order by wet cleaning and paying attention to hard-to-reach places. It is better to wash bed linen and curtains at high temperatures.

  • Pack all food in containers and sealable bags.
  • Take care where you will be for 5 hours after disinfestation, taking into account the toxicity of the product used.

  • Remove personal items from the treatment area.
  • Check the plumbing and fix any leaks to prevent damp from creating.

Actions after disinfestation:

  • Clean frequently used surfaces with a soap and water solution, including the refrigerator and other areas.
  • If you have lost sight of personal items, wash them after the specialists arrive, similarly with textiles.
  • After airing the room, pay attention to your health. If you experience dizziness or nausea, leave the room and contact the health service.

Thus, you become a key link in the pest control process, investing your efforts and attention in successfully solving the problem.


Why do cockroaches appear after disinfestation?

The ineffectiveness of the treatment does not always indicate the uselessness of the product used. Often the reason lies in incorrect actions after disinsection, such as improper removal of drug residues from surfaces.

How long does it take for cockroaches to die after disinfection?

The death of cockroaches is a process that does not occur instantly, but is prolonged. During the first 3 hours, many individuals begin to die, and after 5 days, most of them die. However, complete elimination of insects takes time, and encountering them after 2-3 weeks indicates the need for repeated treatment.

How long should you wait after pest control of cockroaches?

Return to the premises is permitted 5 hours after disinfestation, after which it is important to ventilate the premises. Most cockroaches already die at this time. If a change in the lifestyle of insects is noticed, manifested by their activity in the morning, this indicates their poisoning and impending death.

How long does it take to remove cockroaches?

After 3-5 days, a noticeable effect is visible, but complete destruction of insects may take several weeks. Young cockroaches in the ooteca remain resistant to poisons. After hatching, they leave the nest and, exposed to the drug, die.
