Emerald Ash Borer
Agrilus Planipennis Emerald Ash Borer, is an ash tree-killing insect from Asia. The department has developed a response plan, battling the pest through detection, regulation, and education to protect the state’s more than 3.8 billion ash trees.
EAB kills ash trees within three to five years of infestation. Adults are dark metallic green, 1/2 inch in length and 1/8 inch wide, and fly only from mid-May to September. Larvae spend the rest of the year developing beneath the bark.
