Woodpecker activity

It is difficult to detect emerald ash borer in newly infested trees, as it first infests the tops of ash trees and works its way down. Signs of infestation may include the presence of metallic-green beetles about a ½" long on or around ash trees, thinning and yellowing leaves, D-shaped holes in the bark of the trunk or branches, unusually large amounts of woodpecker activity as it feeds on the larvae and shoots growing from the base of the tree.
