Hornet spray safe for an Oregon Myrtle/California Bay treee?
Hello. We have a large yellow jackets nest inside a hole at the base of our large bay tree. The tree is somewhere between 90 -300 years old. I noted the warning on the can of hornet spray saying it was not safe for evergreens or holly. Would this spray actually have an effect on our tree?
Use of this product on evergreen and holly is not recommended as damage may result.
