Your beloved ash trees could be suffering from something besides Emerald Ash Borer (EAB) in West Chester, but you want to be safe! If your trees are showing two or more of the symptoms below, chances are good that the EAB has arrived. Work with a certified arborist for early EAB detection for improved chances of a successful treatment and to stop the spread of this destructive wood-boring beetle.

Symptoms of EAB Infestation

Look for these telltale signs your ash tree is suffering from EAB infestation. In order to properly identify the presence of this Asian native, look for a combination of two or more symptoms.

     •  Crown Dieback – as a result of multiple years of EAB infestation, the larvae will disrupt the delivery of nutrients and water flow to the upper canopy, resulting in dieback of the upper and outer crown.
     •  Epicormic Sprouting – as a defense mechanism, your trees will try to ensure survival when sick or stressed. Signs of new growth at the base of the tree or on the trunk—often just below where larvae are feeding, are indicative of infestation.
     •  Splitting Bark – feeding EAB larval galleries will develop surrounding callous tissue, causing vertical splits to the bark. When the split bark is pulled away, these larval galleries can be seen.
     •  Woodpecker Feeding – woodpeckers love to feed on EAB larvae underneath the bark. With excessive feeding on large numbers of larvae, the damages will look like strips of the tree’s bark have been removed.
     •  D-shaped holes in bark – emergence holes are made as the larvae mature into adult beetles and emerge from underneath the bark.
