Where has EAB been found?
Related Documents     Related Images

EAB was first discovered in North America near Detroit, Michigan in 2002. Since then the beetle has spread to Canada and more than a dozen states, including Wisconsin.

Emerald ash borer was found for the first time in Wisconsin in August 2008 near the community of Newburg, several miles northeast of West Bend.

Since then, emerald ash borer has been confirmed in Brown, Crawford, Dane, Dodge, Douglas, Fond du Lac, Kenosha, La Crosse, Milwaukee, Ozaukee, Racine, Rock, Sauk, Trempealeau, Vernon, Walworth, Washington, Waukesha and Winnebago counties. These counties are under quarantine. Jefferson and Sheboygan counties are under quarantine because of their proximity to infestations in neighboring counties. We have not confirmed the presence of EAB in either of those two counties, however.
