The primary mechanism of contact poisons is through physical contact with the organism's body. Contact poisons are designed to enter the body of pests directly upon touching them. These substances are formulated to affect the pest's physiology when they come into contact with the pesticide, which can lead to various harmful effects such as paralysis, disruption of normal bodily functions, or death. This is in contrast to other types of poisons, which may require ingestion, inhalation, or absorption through the skin as their primary mode of entry.

Ingesting poisons would involve the pest consuming the toxic substance, while inhalation requires the pesticide to be airborne for the pest to breathe it in. Absorption through the skin implies that the poison needs to penetrate the outer layer of the pest’s integument, which is not the primary mechanism for contact poisons. Overall, understanding the specific nature of contact poisons helps in the effective application and management of pest control strategies.
