The insecticide enters the body through the skin. In insects, the skin is called the cuticle. Insecticides of this type are called contact poisons.

Entering the skin can happen when:
The droplets of aerosol spray hit the insect
The insects walk in and come into contact with powder or granular forms of pesticides


The pesticide enters the body through the mouth when the insect eats it. Insecticides of this type are called ingested poisons. An insect can ingest an insecticide:
As a bait (food to which a pesticide has been added)
When he “cleans” himself after coming into contact with the poison
Enter the respiratory system

The insecticide is inhaled by the insect. These insecticides are called inhaled poisons.

Insects do not breathe through the mouth as most animals do. They breathe through openings (small openings along the side of the abdomen).
