Emerald Ash Borer

This insect is an invasive species from Asia. The larvae of the beetle destroy the vascular system of the tree causing dieback and death. Trees infested with the beetle have no natural defenses to the insect and will die within 3-5 years of the initial attack. Trees located in areas with a high bore population can die within as little as one year. By the time an ash tree shows obvious damage, it is usually too late to treat for EAB. Preventative treatment is the only method to protect and save your ash tree.
