Emerald Ash Borer (EAB)

The Emerald Ash Borer is a beetle that has become destructive to the ash trees in our area. Unfortunately, by the time the damage is noticed, it is too late: the tree is too far gone and needs to be removed. You need to have a proactive approach rather than a reactive approach to save the ash tree. In order to protect ash trees and avoid the spread of EAB, it is important not to transport firewood outside its local area. If you feel your tree may be infected, please contact our office to make arrangements to have an arborist diagnose your ash tree further.

Signs and Symptoms

One of the most visible signs of EAB infestation is crown dieback. You will see branches at the top of the crown die, and more branches will die in subsequent years. As the tree declines, new branches known as suckers will sprout at the base of the trunk. Also, adult beetles emerging from the tree will leave “D”-shaped exit holes, approximately 1/8-inch diameter, anywhere on the trunk or upper branches. Woodpeckers may feed on the beetle that has left visible damage on the bark.
