How do you get rid of stinging caterpillars?

Question:They're in my trees and I don't know how to kill them. And there's a lot of them, like hundreds! What should I spray on my trees to get rid of them?

Answers:
You could use an insecticide like Triazicide, which can be sprayed using a hose applicator. If you'd rather not use an insecticide, you could try knocking them out of the tree with a strong blast of water, or try spraying soapy water on them which will plug up their pores so that they can't breathe. As a last resort you can cut down the trees and stomp them.
