One of the earliest signs of damage caused by EAB on ash trees is woodpecker damage. The birds are experts at detecting infestation under the bark and will flake the bark off in search of the larvae. The tree with minimal damage is young and showing early signs of infestation, while the more heavily damaged tree is dead. Again, in the Rochester/Finger Lakes area we do not need to wait for signs of infestation. This deadly pest is on its way and the sooner we act to treat existing ash trees, the better success we will have.
