Tell us something we didn’t know: Bug traps throughout Brandon caught more mosquitoes this week than last week.
However, the numbers are still not high enough to trigger fogging with malathion. And the good news is that city staff say there are not very many ready to hatch.
The city says that Sunday trap counts averaged 246 mosquitoes, followed by 149 mosquitoes Monday. That’s up from 210 and 31 a week prior.
The highest count over the past two days was in the cemetery, where 482 of the biting bugs were nabbed on Sunday. The lowest level was 53 mosquitoes caught near the Brandon University gym.
A “bad catch” prevented tallying the numbers from the Canada Crescent trap, but overall the numbers were higher on Sunday and lower Monday.
Considering other factors, like larval life cycles and weather forecasts, the city calculates an Adulticiding Factor Analysis level of 12 for this week. That’s up from 10 last week, and nine the week before.
The AFA has to hit at least 15 (out of 18) for two consecutive counts before the city will consider sending out the malathion trucks, although fogging can also be triggered by finding an average of more than 1,000 mosquitoes in the traps, or if any individual trap catches more than 2,000.
The city may also fog if ordered to by the province, for example to combat West Nile virus.
With relatively cool weather expected this week, the city says there are currently no plans to prepare for fogging.
But people who want a buffer zone around their property in the event of fogging should apply in advance. With name, address, phone number and proof of residency, they can apply for a buffer zone in person or in writing, and a medical certificate is not required.
Buffer zone applications are available online at brandon.ca or people can call 204-729-2148. Buffer zones do not apply if health-related fogging is ordered by the province.
Meanwhile, workers last week concentrated on larviciding — and it seems to be paying off. So far, they say they’ve seen very little larvae activity at test sites this week. They will continue to monitor larvae populations throughout the week, and will larvicide where necessary.
