Emerald Ash Borer (EAB)
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.
On June 17, 2009, Emerald Ash Borer was confirmed in New York.
