Brad from Hagerstown, Md writes,
I have a caterpillar eating the top of a blue spruce tree. What product do you recommend to kill them?
The tree is about 7 feet tall and the caterpillar or worms are all over.
It is important to have the caterpillar identified so that we can make the best product recommendation for your needs. Without the exact identification we would recommend Talstar P as it is a broad spectrum insecticide that can be sprayed on blue spruce trees.
