Emerald Ash Borer (EAB) is an introduced insect pest from Asia.
EAB attacks and kills all species of true ash trees, (those trees within the genus Fraxinus, not mountain ash).
EAB feeds beneath the bark and disrupts the flow of water and nutrients within trees.
Tree mortality will occur if a tree is infested, and not treated with pesticide. It may take as little as one year, however death normally occurs within 2-3 years of infestation.
