We often get calls with clients stating insects are attacking their trees and would we come spray them.Before you have a chemical spray application done, make sure you really have insects...
August is a time when heat has had a lot of effect on the tree's ability to move water throughout the leaf canopy. Often the vascular system can not move enough water to support all the little individual cell membranes in that leaf. The result is the membrane dies and is blown out by the wind, creating an effect we call leaf tatter. This may look like insects are chewing on the leaves.
So before you spray, look for the actual insects at different times of day and inspect the actual damage for chew marks or the irregular shapes of individual cells.
