Winnipeg is activating its adult nuisance mosquito fogging program after a spike was detected in bug populations.

The city says in a news release that the citywide rating on its Adulticiding Factor Analysis, which includes trap counts, moved from medium to high on Saturday.

Fogging begins Sunday night in selected areas, weather permitting, and will continue until Monday morning.

Residents can apply for a 90-metre buffer zone in order to exempt their property.

The city says insecticide DeltaGard 20EW will be used in accordance with federally approved label directions and will be applied by licensed applicators.

The Manitoba government says on its website that the insecticide was approved in May 2017 in Canada for wide area mosquito control.
