Pesticide Use for Mosquito Control
Between June 19 and October 31, 2023, the City of Barrie is conducting a larviciding program under the authority of the Local Medical Officer of Health to control larval mosquitoes in order to prevent their development into vectors of West Nile Virus. The pellet formulation of Altosid Methoprene Pellets Mosquito Growth Regulator PCP#21809 or the pouch formulation of Vectolex WSP Biological Larvicide PCP#28009 will be placed into municipal owned catch basins of storm drains within the boundaries of the City of Barrie.
All larvicide will be applied by applicators, licensed by the Ministry of the Environment, Conservation and Parks, or their supervised technicians. Municipal owned catch basins on private property (rear Lot Catch Basins) will be treated upon request of the homeowner with Altosid XR Briquette PCP#27694. A consent form must be signed by the homeowner prior to treatment.
For additional details on the locations and dates of treatment please call (705) 739-4219.
Prior to the commencement of the larviciding program, the City cleans out all catch basins, which ensures that they are free of sediment and water and that the larvicide will remain in place for the appropriate time period and will not be flushed out. Additionally, the contractor does not apply the larvicide during rain events and uses a calibrated dispensing tool to ensure there are no excess amounts of larvicide. These methods prevent the larvicide from being flushed out of the intended catch basins and into the waterway.
As Central Ontario’s premier waterfront City, Barrie is committed to providing residents with opportunities to enjoy an enhanced and secure quality of life in a prosperous and ecologically sustainable community.
A healthy city needs a strong green infrastructure. More than 75% of the land in Barrie is privately owned; property owners play a vital role in sustaining Barrie's urban forest.
