Midges Drive Deadly Deer Outbreaks in Wisconsin, Virginia, and Pennsylvania
Epizootic hemorrhagic disease (EHD) is causing significant deer mortality across multiple US states. In Wisconsin, over 700 dead deer have been reported in Washington and Waukesha counties. Virginia and Pennsylvania have also confirmed cases, with Pennsylvania noting seven deaths in Chester County. The virus, spread by midges, does not infect humans but poses risks to livestock. Outbreaks typically end with the first frost.
Key points
- Wisconsin's DNR reports 600 dead deer in Washington County and 100 in Waukesha County.
- Virginia's DWR reports sporadic deer mortalities consistent with hemorrhagic disease.
- Pennsylvania's Game Commission confirmed seven EHD deaths in Chester County.
- EHD is transmitted by biting midges and does not infect humans.
- Outbreaks usually end with the first frost, which kills the midges.
Background
Previous coverage in September 2026 highlighted the expansion of EHD in southeastern Wisconsin, with over 700 dead deer reported in Washington and Waukesha counties. The DNR confirmed EHD in samples from Washington County and noted that the virus is spread by midges.

Why it matters
EHD outbreaks can significantly impact local deer populations and may affect livestock. While the virus does not infect humans, it poses risks to ruminant livestock. Understanding the spread and transmission of EHD is crucial for wildlife management and public health.
What to watch
Residents are encouraged to report sick or dead deer to local wildlife agencies. Outbreaks are expected to end with the first frost, which kills the midges that transmit the virus. Continued monitoring and testing will help track the spread of EHD.
