City of Brandon Mosquito Surveillance Begins This Weekend

May 30, 2023

Brandon, MB – City of Brandon Parks & Recreation Services will begin its annual mosquito surveillance and abatement program this weekend for the 2023 season. The program focuses on monitoring and larviciding dozens of areas of standing water across the community, with provisions in place for adult nuisance mosquito control (fogging) if conditions meet criteria.  

In this early part of the nuisance mosquito season, focus is being placed on larviciding areas of standing water with a biological larvicide (Aquabac) where necessary and the weekly collection and analysis of adult mosquito trap counts collected from static locations across the community.  

The City of Brandon will undertake adult nuisance mosquito control (fogging) if the City of Brandon’s Adulticiding Factor Analysis Guidelines value falls into and remains in the high category for two consecutive trap counts; OR the average of any daily mosquito trap count is more than 1,000 nuisance mosquitoes; OR any individual trap count is more than 2,000 nuisance mosquitoes. These guidelines do not apply if the Province of Manitoba issues the City of Brandon a fogging health order to control any presence of West Nile virus.  

Residents can also help reduce the impact of this year’s mosquito populations. Simple things like dumping out any containers of standing water, draining any eavestroughing, covering rainwater collection containers; filling in any low-lying areas, or treating problem areas with biological larvicide can minimize the number of mosquitoes. The annoyance of mosquitoes can also greatly be reduced by using repellants, wearing light-coloured clothing, limiting your time outside between the hours of dusk and dawn and using screened-in areas.
