Emerald Ash Borer

Emerald ash borer (EAB) is an invasive pest that has killed millions of ash trees across the Midwest and Eastern United States over the past few years, and threatens to kill millions more as it spreads to new areas. EAB infestations have been documented in Illinois, Indiana, Kentucky, Maryland, Michigan, Minnesota, Missouri, New York, Ohio, Pennsylvania, Virginia, West Virginia and Wisconsin, with more state confirmations expected soon.

It is of utmost importance that homeowners and municipalities understand how to identify the pest, protect ash trees from infestation and treat trees already showing early symptoms of EAB damage. Therefore, we've compiled a number of links, resources and tools we hope will be a useful supplement to your university's EAB communications. We will continue to update this site as new sources of information become available.

E-mail us with a suggested link or additional information to include on this page.

About Safari® Insecticide

Safari Insecticide has been shown to help control EAB when applied to the soil or as a non-invasive basal trunk spray. The ease of application and low cost of Safari compared to that of removing a tree provides homeowners, municipalities and businesses with a realistic option for helping protect ash trees from EAB rather than chopping them down.
