How do insecticides work?
I need to know what they do to the insects. I know that one way that insecticides work is they are poisoned through their food. I need to know one more. If you could help, that would be great. Thanks!

Depends on the product. Some are contact pesticides - the insect dies when it comes in contact with the insecticide. Others sre systemic - it is absorbed into the host plan and the insect dies when ingests the foliage of the plant.
