Emerald Ash Borer or EAB as it’s commonly known, is a small, metallic-green, invasive wood-boring beetle native to east Asia that attacks and kills ash trees. Adult beetles live on the outside of trees and feed on the leaves during the summer months, while the larvae feed on the living plant tissue, the phloem and cambium, underneath the bark. The tunneling and feeding activity of the larvae is what ultimately kills trees. EAB attacks trees of any size, age, or stage of health, and trees can die within two years of infestation.
