The fogging trucks have been rolling, or will be shortly, in Headingley and St. Francois Xavier.
The decision to fog for mosquitoes within the two municipalities is made based on local trap counts and residents’ complaints.
Since mosquitoes don’t respect municipal boundaries, if trap counts are high in St. James and Charleswood, then there are likely close to the same number of mosquitoes pestering people in Headingley and St. Francois Xavier.
The village of St. Francois Xavier was fogged on July 5 — a few days ahead of the City of Winnipeg — while residential sections within the RM of Headingley were scheduled for fogging on July 10.
RM of Headingley CAO Chris Fulsher said it takes seven or eight hours and costs approximately $1,500 to make the rounds using a truck-mounted sprayer and ATV for off-road locations.
Malathion and propoxur were used in Headingley and malathion only in St. Francois Xavier.
"Our licence permits us to fog when the mosquito landing count averages one per minute over a 10-minute period. We also monitor the counts of two City of Winnipeg mosquito traps located in the RM," Fulsher said.
St. Francois Xavier CAO Robert Poirier said a round of fogging within the village costs about $400.
The last time fogging was done in that area was in 2010, while Headingley was last fogged in 2011.
In both municipalities, residents are encouraged to drain any standing water on their properties to reduce breeding sites. Fulsher and Poirier said it’s possible that another round of fogging could take place if mosquito numbers increase.
