WINNIPEG — A surge in the city’s mosquito population will put fogging trucks back on the streets beginning Sunday night.

Fogging will be carried out starting August 21 between 9:30 p.m. and 6:30 a.m., weather permitting. Crews will continue to fog until further notice and the city will be releasing areas to be targeted in the coming days.

On Thursday, the city-wide New Jersey light trap count was 73 and the Adulticiding Factor Analysis (AFA) was high.

Ken Nawolsky, superintendent of Insect Control, says the city will be using a stockpile of Pro Malathion ULV purchased in 2009. Because of its age, it had to be lab-tested and approved for use by Health Canada. It also met the World Health Organization standards for isomalathion content.
