Emerald Ash Borer
If you have ash trees, stop and learn more before you act.


The potential threat of emerald ash borer (EAB) is real; however, acting without  understanding the specific threat to your trees, regulations and quarantines, and your options, could cause the unnecessary loss of treasured shade trees, or loss of substantial income from your woodlot. This Asian beetle infests and kills North American ash species (Fraxinus sp.) including green, white, black and blue ash. Thus, all native ash trees are susceptible. Adult beetles leave distinctive D-shaped exit holes in the outer bark of the branches and the trunk. Adults are roughly 3/8 to 5/8 inch long with metallic green wing covers and a coppery red or purple abdomen. They may be present from late May through early September but are most common in June and July. Signs of infection include tree canopy dieback, yellowing, and browning of leaves. Most trees die within 2 to 4 years of becoming infested. The emerald ash borer is responsible for the destruction of over 50 million ash trees in the U.S. since its discovery in Michigan. For more information and pictures.

If you think you have EAB, call the Department's EAB and Firewood hotline at 1-866-640-0652.
