The City of Selkirk has scheduled nuisance mosquito fogging starting on June 28 at 10 p.m., weather permitting. Fogging is also scheduled for the nights of June 29 and if required, June 30.
The decision to fog comes after several weeks of biological larviciding as well as monitoring mosquitoes in two Province of Manitoba traps located in the city. One is on Sophia Street and the other is on Dorchester Avenue. From May 29 – June 4 counts were low, averaging just five mosquitoes per night. From June 5 – 11, counts were again low, averaging 2.75 per night. During the third week, from June 12 – 18, numbers increased, with nightly counts of 79.5. Despite the increase, this number is far lower than the 250 count which is the point at which fogging typically considered.
Dan McDermid, the city’s director of operations, said the increase in count numbers in Week 3, the weather, which featured heavy rain followed by heat and sunshine, and the upcoming Canada Day celebrations at The Waterfront, combined to encourage fogging.
“The counts have slowly increased over the last three weeks. The sudden increase in the last week and the anticipated jump next week is why we’re fogging,” McDermid said
Mosquito Fogging in time for Canada Day Celebrations
“The best time to fog is one to two days prior to a major event, so with Canada Day coming on July 1, an event that will bring 10,000 people to The Waterfront, where they’ll be standing and sitting on grass, we had to take that into consideration.”
McDermid said the city’s strategic plan makes environmental stewardship a priority and before the decision to fog was made, the city undertook biological larviciding as part of its mosquito control program earlier this spring. Biological larviciding targets larvae in their breeding habitat, before they mature into adult mosquitoes and disperse.
“We’ve been larviciding for about eight weeks, putting in roughly 15 hours a week, trying to control the mosquitoes in a more environmentally responsible way,” McDermid said.
While larviciding has dramatically slowed the increase in mosquito population, the anticipated increase in the adult mosquito count necessitates fogging.
The city has again contracted reputed entomologist Randy Gadowski to deliver the city’s fogging program. Fogging will begin at 10 p.m. each night and stop at about 4 a.m. Fogging will be split into two nights, with everywhere west of Main Street being done on June 28 and everywhere east, including the golf course and parks, done on June 29. If weather limits or delays fogging on those nights, the contractor will complete fogging on the third night. The contractor will use Malathion.
The city recommends that during fogging, residents keep windows closed, air conditioners turned off and that pets be brought inside. Operators of the fogging trucks will stop fogging if pedestrians approach, but the city advises if you see the fogging vehicles, which will be well lit, try to take another route.
Fogging Does Not Eliminate Mosquitoes
“We’re not going to eradicate every mosquito out there, we’re just going to try to control them so people can enjoy the outdoors more comfortably,” McDermid said. “Even after the fogging, people can expect to contend with mosquitoes particularly at dusk. Taking personal protection efforts, such as wearing mosquito repellent or covering skin at peak mosquito hours, will still be something people will want to do.”
Citizens can help with the city’s mosquito control program by preventing artificial mosquito breeding sites by:
- ensuring that rain barrels are covered;
- garbage and recycling bins are covered or turned upside-down;
- emptying or changing the water in birdbaths and other lawn ornaments twice a week; and
- keeping eavestroughs clear.
If you don’t want your property included in the fogging program, register through CitizenSupport or call 204-785-4930. A 90-metre buffer zone around your property line will not be fogged.
