Getting rid of cockroaches in an apartment is not always an easy task and often requires several attempts to achieve complete success. Cockroaches are persistent insects that can quickly adapt and acquire stable immunity to most insecticides. In this context, we will consider the effectiveness of smoke bombs against cockroaches and what precautions should be taken when using them.

The most important thing: is it possible to use a smoke bomb against cockroaches in an apartment?

No, the use of smoke bombs is only recommended in spacious, well-ventilated rooms or open areas. In city apartments, united by a common ventilation system, smoke from a bomb can spread to neighbors, posing a potential risk to their health. To get rid of cockroaches in an apartment more safely, it is recommended to use the cold fog treatment method.

How do smoke bombs work against cockroaches?

Insecticidal bombs are an effective means for treating large areas. Unlike other forms of insecticides such as aerosols, gels and crayons, and dusts, the use of smoke bombs does not require waiting for insects to walk across the treated surface or eat the toxic mixture. The smoke emitted by the saber has an immediate effect on cockroaches and can quickly destroy the population along with the larvae.

The insecticide composition first penetrates the chitinous layer into the respiratory tract of insects, causing paralysis and subsequent death. Even if some cockroaches survive the treatment, they will pick up the poison from floors, walls and furniture. When trying to clean the antennae, they will also ingest toxic substances, which will lead to their death.

Where are insecticidal smoke bombs used?

It is important to note that the use of smoke bombs is recommended only in spacious rooms. The compositions of the checkers may vary by manufacturer in terms of the content of active components, radius of action and concentration. If you need to treat a regular living space, it is recommended to choose less concentrated options. Powerful compounds are suitable for use in open areas and industrial premises.

Smoke bombs are effective for treating the following areas:

  • Hangars;
  • Basements;
  • Garages;
  • Dachas and private houses;
  • Large residential and industrial buildings;
  • Open areas.

Precautions when using smoke bombs

Important to remember: be sure to follow the instructions! The smoke from smoke bombs designed to kill cockroaches contains toxic substances, so all precautions must be followed to avoid unpleasant health consequences.

Take the following precautions:

  1. Use protective equipment. Wear long sleeves, thick pants, gloves and a face mask.
  2. Avoid inhaling insecticidal smoke. Leave the room as soon as possible after launching the checker.
  3. After the effect of the checker has ended, thoroughly ventilate the room by opening all windows and doors. Perform this procedure quickly, holding your breath to prevent smoke from entering your lungs.
  4. After completing the treatment, take a shower to remove any remaining insecticide from the skin.
