City of Brandon Mosquito Surveillance & Abatement Program Now Underway

May 28, 2020


Brandon, MB – City of Brandon Parks & Recreation Services wishes to advise the public that it has begun its annual mosquito surveillance and abatement program for the 2020 season. Conducted each summer in cooperation with Brandon University’s Biology Department, 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.

The City of Brandon will ONLY 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 if 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.

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. Trap count data for the 2020 season will be available on the City of Brandon’s Mosquito Abatement Program Information Page beginning in early June.

In accordance with approval granted by Health Cananda’s Pest Management Regulatory Agency, the City of Brandon will undertake any potential adult nuisance mosquito control using the product, Delta Guard 20 EW (Deltamethrin). Compliant with its annual Pesticide Use Permit issued by the Province of Manitoba, the City of Brandon allows residents to register for a 90-metre buffer zone to be applied to their property in the event the City of Brandon fogs for nuisance mosquitoes. A resident’s name, address, telephone number and proof of occupancy are all required for a buffer zone application to be accepted. A medical certificate is NOT required to request a nuisance mosquito buffer zone. However, should the Province of Manitoba issue the City of Brandon a health order to spray for West Nile virus, all buffer zones will NOT apply. More information about the use of Delta Gard 20 EW can be found here.
