How do contact pesticides work?

Explanation:
Contact pesticides kill pests through direct interaction with the chemical on the pest’s body. When a pest touches a treated surface or droplet, the active ingredient acts on its outer tissues (often crossing the cuticle or disrupting nervous function) and can cause rapid death or incapacitation. This is different from pesticides that require ingestion (stomach-action) or those that work mainly by inhaling vapors (fumigants). So the most accurate description is that these products work by touching the pest.
