Mosquito Fogging Begins Thursday, June 17

24 hour notice:  Adult nuisance mosquito fogging to begin

To date, the Insect Control Branch (ICB) has used a combination of larviciding and residual treatments to control mosquito populations. These measures alone are no longer sufficient to control the current adult nuisance mosquito population, therefore an adult nuisance mosquito fogging program will be implemented. Fogging will begin on Thursday, June 16, 2016, between 9:30 p.m. and 6:30 a.m.


Daily Announcements & Insect Management Areas

Public Service Announcements (PSAs) will be released daily at least eight hours in advance of fogging. These PSAs will identify the Insect Management Areas the Insect Control Branch is planning to treat that evening, weather permitting.

Until further notice, fogging will be carried out on a daily basis between the hours of 9:30 p.m. and 6:30 a.m. Fogging will not occur when temperatures are below 13 degrees Celsius and/or wind speeds are not conducive to fogging.

The insecticide Pro Malathion ULV® will be used. This insecticide has been approved for use in Canada by Health Canada’s Pest Management Regulatory Agency. Pro Malathion ULV® will be used in accordance with federally approved label directions by licensed pesticide applicators.
