WINNIPEG – The city’s insect control branch will fog for mosquitoes again starting Thursday at 9:30 p.m., weather permitting.

The city-wide average adult mosquito trap count Thursday was 68, with the worst region being the city’s northwest, where an average of 158 mosquitoes were counted – and where fogging will start. The highest trap count Thursday was 336 mosquitoes in West Kildonan near the Red River.

Insect management areas 40-51 are scheduled to be fogged Thursday night. In addition to West Kildonan, Wolseley, much of the West End, the city core, the North End, Inkster, Garden City, Jefferson, Seven Oaks, Amber Trails and Old Kildonan will be sprayed. A full list of insect management areas can be found below the map.
