WINNIPEG – Malathion fogging to control nuisance mosquitoes has been suspended because low temperatures are forecast Monday night.
Mosquitoes aren’t active when temperatures are low, and fogging is most effective when the insects are flying and make direct contact with the malathion, a city news release said. Fogging is suspended when the temperature drops below 13 C; Environment Canada forecasts a low of 9 C Monday night.
The fogging scheduled for Sunday night wasn’t completed because of low temperatures, the news release said.
The southern and western parts of Winnipeg were fogged on the nights of June 11 and June 13. Insect management areas 1-10 (east of the Red River and north of Marion Street and the Symington Yards) and areas 40-51 (east and north of the airport, including most of the West End, the city centre, the North End, West Kildonan and north to the city limits) are the only areas that haven’t been sprayed. Go to the City of Winnipeg insect management branch website to learn which insect management area you live in.

The mosquito adulticiding factor analysis – the tool the city uses to help determine whether to fog – was high on Monday, with an average trap count of 27. Despite the fogging last week, the highest count was in the southwest, with an average of 38 mosquitoes per trap; the southeast had the lowest average, at 15. The average count in the northwest was 22 and the average in the northeast was 32.
