It is difficult and unnecessary to control maple petiole borers. They do not cause serious damage and their activity from year to year is unpredictable.
How do you get rid of petiole borers?
Raking leaves up will not help reduce the borers since the larvae are not in leaves that have fallen to the ground. This is one of those moments when the best course of action is no action. Mulching leaves back into the turf is the best method for disposing of the fallen leaves.
