They're in my trees and l do not know how to kill them. And there is a lot of them, like hundreds! What should l spray on my trees to get rid of them?
How do you get rid of stinging caterpillars
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 not breathe. As a last resort you can cut down the trees and stomp them.
