Why do pests come back? Common mistakes after extermination

Why do pests come back?

Common errors after deletion

When it seems like everything is over after pest control, you suddenly notice ants again , hear gnawing sounds in the walls , or even smell an unpleasant odor.
Why does this happen? The reason is improper behavior after the procedure or insufficient preparation before it .


1. The source of infection is not eliminated

After the procedure it is necessary:

  • Clean all surfaces

  • Remove food residue, crumbs, waste

  • Seal trash cans and storage areas tightly

Even a small remaining source of infection allows the population to regenerate .


2. Unfinished cycle

Some species (e.g. bedbugs, cockroaches) have multiple stages of development . If the procedure is stopped too early, new individuals will hatch from the eggs.


3. Independent, unprofessional testing

Sprays from stores or folk remedies do not provide long-term effects . Even worse, pests become more resistant.


4. Prevention is not followed

After destruction, you need to:

  • Seal cracks, openings, ventilations
