Correct Answer: Immediately kills the prey
Description: Dichloro-diphenyl-trichloroethane (DDT) is primarily a contact poison. It acts on nervous system of insects. It permeates into the insect body through the cuticle, after dissolving in the waxy covering of the feet, and causes of paralysis of legs and wings, convulsions and finally death.
