Details of latest confirmation: Emerald ash borer has been detected in the village of Greendale at 43rd Street and West Ramsey Ave. Larvae, an immature life stage, were collected after extensive woodpecker damage in trees was observed and a Department of Natural Resources urban forester was notified. Village officials submitted photos Feb. 8 to the Wisconsin Department of Agriculture, Trade and Consumer Protection, where an entomologist positively identified them as EAB. Milwaukee County is already under quarantine for EAB and this latest find in Greendale does not change the quarantine status.
Where else has EAB been found in Wisconsin: The tree-killing emerald ash borer has been discovered so far in 13 Wisconsin counties, including this latest find in Milwaukee County. The other counties are Brown, Crawford, Kenosha, La Crosse, Ozaukee, Racine, Rock, Trempealeau, Vernon, Walworth, Washington and Waukesha counties.
Quarantined counties: State and federal EAB quarantines currently exist in 15 Wisconsin counties: Brown, Crawford, Fond du Lac, Kenosha, La Crosse, Milwaukee, Ozaukee, Racine, Rock, Sheboygan, Trempealeau, Vernon, Walworth, Washington and Waukesha counties. Any ash material that could transport a life stage of the beetle is prohibited from being moved out of the quarantine area. This includes all hardwood firewood, regardless of tree species.
