Emerald Ash Borer

The Emerald Ash Borer was discovered in Tennessee in July 2010 and in Hamilton County in July 2013. This destructive insect’s range slowly but surely expanded from its original infestation in Michigan across several states and Canada, leaving whole stands of ash trees decimated in its path. Thus far, EAB has killed tens of millions of ash trees in southeastern Michigan alone, with tens of millions more lost in Illinois, Indiana, Kentucky, Minnesota, Missouri, New York, Ohio, Ontario, Pennsylvania, Quebec, Virginia, West Virginia, and Wisconsin.

For information specific to Tennessee, see Emerald Ash Borer on the Tennessee Department of Agriculture website.

This website includes EAB symptoms list, quarantine rules and map – which includes Hamilton County! – and a report to fill out if you suspect EAB on a tree in your area.

The UT Extension Service distributed this fact sheet to extension agents statewide to help identify and then treat EAB infestations – Insecticide Options for Protecting Ash Trees from Emerald Ash Borer.

The Emerald Ash Borer University website is a collaborative effort of the USDA Forest Service, Michigan State University, Purdue University and Ohio State University.

The website provides the latest information on the Emerald Ash Borer for the United States and Canada. The website has an infestation map, what’s new, what’s being done, what to know, and contact information. This site also information insecticide options, and webinars on many topics concerning EAB.
