Emerald Ash Borer Detected in St. Croix County

Emerald ash borer has been detected for the first time in St. Croix County. This is the first new county detection of 2018 for Wisconsin. An inspector for the Wisconsin Department of Agriculture, Trade and Consumer Protection collected an adult EAB in a parking lot in the city of Hudson on June 28 after a local resident noticed and reported symptoms. Although the tree appeared to be infested for some time (multiple S-shaped galleries and D-shaped exit holes), nearby ash appear healthy. The U.S. Department of Agriculture Animal and Plant Health Inspection Service confirmed on July 10 that the insect was EAB. To date, EAB was found in 49 of the state’s 72 counties, including Door County.
