The Emerald Ash Borer (EAB) is an invasive insect native to Asia that has killed millions of ash trees. First discovered in Michigan in 2002, the EAB has been identified in 30 states (primarily in the Midwest, Mid-Atlantic, and Southeast). The beetle larvae feed on the inner bark of ash trees, disrupting the tree’s ability to transport water and nutrients. Mortality can be swift, and identification of ash trees that may be infested with the EAB can be difficult.

How can landowners help protect ash on their property and elsewhere?

We recommend the following:

• Educate yourself – Visit the Emerald Ash Borer website to learn more about this invasive pest, including how to identify it and what your treatment options may be.
• Follow the beetles – Researchers have been tracking areas where the beetle has been found. Visit the EAB Detection webpage for up-to-date information on beetle detection and distribution.
