Emerald Ash Borer (Agrilus planipennis)

What it is:

This wood-boring beetle is
smaller than a penny – only
0.33 to 0.5 inches in length.
Metallic green adults emerge
from D-shaped holes May –
June and are active through
summer. Various similar-looking
species exist.

Why it’s a problem:

The larvae eat the inner bark
of ash trees (Fraxinus spp.),
which kills them. The loss of
Oregon’s ash trees will have
economic and environmental
impacts. Ash are long-lived
trees that play an important
role in shading waterways.

How to manage:

Early Detection and Rapid
Response is our first line of
defense. Become familiar with
EAB and report sightings to
or call 1-866-INVADER.
