News - 2021 West Nile Virus Update

The Manitoba government is issuing a ministerial order under The Environment Act to begin spraying for adult mosquitoes with DeltaGard 20EW because of high numbers of adult Culex tarsalis mosquitoes and evidence of infection with West Nile virus (WNV). The order will cover the Rural Municipality of West St. Paul and the City of Winnipeg.

Manitoba Health and Seniors Care reports the hot temperatures and dry conditions experienced this summer have created ideal conditions for Culex tarsalis, mosquitoes that carry the West Nile virus (WNV).
