Emerald Ash Borer: A Serious Threat to Your Trees

The Emerald Ash Borer (EAB) is an invasive beetle that poses a deadly threat to ash trees across North America. Metallic green and only about half an inch long, this pest may be small, but the damage it causes is anything but.

How It Harms Your Trees

Emerald Ash Borers target ash trees by laying eggs in the bark. Once the larvae hatch, they bore into the tree, feeding on the inner bark and disrupting the tree’s ability to move water and nutrients. The result? A slow decline that can kill a healthy tree within just a few years.

Signs of infestation often don’t appear until significant damage has already occurred. These may include thinning leaves, canopy dieback, D-shaped exit holes, and bark splitting. Left untreated, EAB infestation is almost always fatal to ash trees.
