The Minnesota Department of Agriculture (MDA) has confirmed emerald ash borer (EAB) in Blue Earth County. There are now 27 counties in the state with EAB.
A resident in the city of St. Clair was cutting down an ash tree and noticed insect galleries in the wood. The homeowner contacted a local Department of Natural Resources forester who notified the MDA. MDA staff were able to find live EAB larvae and collect samples for federal identification.
