How Insecticides Work - Living History Farm

Insecticides can also be classified by their mechanism of action. Organochlorine compounds work on insects by opening what's known as the sodium ion channel in the neurons or nerve cells of insects, causing them to fire spontaneously. The insect will go into spasms and eventually die. DDT was the earliest of these chlorinated hydrocarbons, but ...
