EHD is a nasty virus. Where I hunt in IL they lost 1/2 the deer herd to a double whammy of EHD and Bluetongue. Bitting midges are the primary vector for EHD. This fall is looking rough due to the flooding from the spring. My area hasn’t had a lot of negative reports yet but it’s still warm. First frost takes care of the problem for the most part. It’s a crappy way to go for these animals.
