Will it kill the tree if I squirt Permethrin directly into the bored holes?
Permethrin SFR 36.8% can be applied to turf, trees and ornamentals for effective insect control. It can be sprayed into or onto damage caused by boring insects,but it is not labeled for injecting or soil drenching as an application for live trees. Always refer to the product label for the correct mix ratios and application rates.
