Emerald Ash Borers

Symptoms

Unfortunately, symptoms of emerald ash borer don’t become obvious until two or more years after borers enter a tree. D-shaped exit holes, just 1/8″ in diameter, mark the emergence of adults. Split bark and foliage dieback may also indicate pest trouble.

Just under the bark, S-shaped larval galleries will confirm the presence of emerald ash borers. Some homeowners may even see an increase of woodpecker activity pecking for the insects.
