It’s hopefully the beginning of the end for Winnipeg’s bloody battle with mosquitoes.

The city will begin adult nuisance mosquito fogging at 9:30 p.m. in the southwest quadrant of the city.

Trap counts in the southwest area have been substantially higher than in other neighbourhoods. Yesterday, trap counts in Assiniboine Park registered 3,552 mosquitoes. The lowest trap count came from the RM of Macdonald where a single mosquito was counted.

The average trap count in the city has hovered just above 200 in the last couple of days.

The neighbourhoods of Assiniboine Park, Charleswood, Royalwood and Waverley will be some of the first ones fogged tonight.

Ken Nawolsky, Winnipeg’s insect control superintendent, said at a press conference on Friday that the city’s fogging schedule will be planned around necessity—the areas with the highest trap counts will be first priority.

The city will be using malathion and pyrocide to ward off the mosquitoes. Both insecticides have been approved by Health Canada. Permanone will be the chemical of choice for residual treatments.

Fogging will happen nightly from 9:30 p.m. until 6:30 a.m. until the city deems the mosquito population is under control, Nawolsky said.

The city has released a map showing all locations to be fogged. You can see it here.

Winnipeg Nuisance Mosquito Trap Counts

The graphic below shows the number of adult female nuisance mosquitoes last observed in each of the city’s traps. In the summer this count is usually updated daily.

Trap locations and descriptions are approximate; the city doesn't release exact locations of traps to avoid tampering and vandalism.

If looking at this graphic makes you itchy — or if you want to also monitor adulticiding factor analysis, quadrant averages, or other city skeeter stats — visit the city’s own trap-count site.

UPDATE: Map is displaying archival data during the off-season. Live reporting will return in Spring 2015.
