For some time now, the Emerald Ash Borer (EAB) has been the predominant topic of discussion when it comes to forest pests, particularly in the eastern United States. It’s naturally found in northern China, Japan, Korea and eastern Russia, and found its way over to our shores sometime in the summer of 2002.
Our Arborjet associates describe the Emerald Ash Borer as “an invasive pest that attacks ash trees (Fraxinus spp.) This metallic wood boring beetle was found in Detroit, Michigan and Ontario, Canada in 2002, and has continued to spread into neighboring states and eventually across the U.S. and Canada. The adult is a small, metallic green beetle only 10-15 mm in length and about 3 mm in width. The larvae live under the bark of the tree and feed in the vascular cambium. The adults typically emerge around June, leaving D-shaped exit holes in the bark. This ash tree insect briefly feeds in the canopy before reproducing and laying eggs in the twigs and branches.”
