In August, two separate infestations of emerald ash borer (EAB) were found in rural areas of Kewaunee County. EAB has spread through Wisconsin over the last few years, so these detections were expected. The first infestation spans the towns of Carlton and Franklin in the southern part of the county. A county resident reported the second infestation, located in the Town of Casco, in late August. The pest is likely present in other parts of the county as well.
