City Control Campaign Stings Mosquito Population

August 05, 2011

Fewer mosquitoes are bugging Edmontonians these days. Between July 26 and August 1, each City light trap attracted an average of 113 mosquitoes, lower than the previous week’s average of 299. Historically, this would have been the peak season for mosquitoes in Edmonton.

Now complete, the City’s fourth control campaign focused on areas where mosquito larvae was found in higher concentrations. Over 14,000 hectares have been treated since the start of this year’s control program. Monitoring of adult mosquito numbers continues at major outdoor festival and event sites. In advance of this weekend’s Folk Music Festival, crews spot treated Gallagher Park because of the higher number of adult mosquitoes detected at this site. This type of control is only used where the adult mosquito population warrants this treatment and when conditions are suitable for a safe, effective application.

Of the over 8,000 mosquitoes collected in all of the City’s mosquito traps across Edmonton over the past week, only two Culex tarsalis mosquitoes were found. Increased monitoring over the past couple of days has identified an additional eight Culex tarsalis mosquitoes. Finding this type of mosquito is not uncommon or unexpected, as these species are typically found in late July and early August, particularly following hot, dry conditions.

The City recommends residents protect themselves against mosquito bites. When enjoying the outdoors, wear repellent, pants and long-sleeved shirts. Loose-fitting and light-coloured clothing also helps prevent mosquito bites. It's also recommended that homeowners remove standing water on their properties to reduce potential breeding areas for mosquitoes.

The City's mosquito control program focuses on treating mosquito larvae in standing pools of water across Edmonton, which is a more proactive, environmentally-friendly and safer approach than treating adult mosquitoes.
