Kanata North Nuisance Mosquito Control Program

Notice of pesticide use

Between April 11 and September 15, 2019, G.D.G. Environnement Ltée. will be applying a biological larvicide by air and ground to stagnant water in order to control larval mosquitoes that impact the residents of Kanata North and the surrounding areas. The program will use multiple ground applications of the larvicides VectoBac 1200L (Bacillus thuringiensis israelensis, PCP #21062, liquid) and Vectolex CG (Bacillus sphaericus, PCP #28008, granular), while VectoBac 200G (Bacillus thuringiensis israelensis, PCP #18158, granular) will be applied by helicopter.

For further information regarding the larvicide application contact GDG: or toll free at 1-877-227-0552.


The Kanata North Nuisance Mosquito Control Program targets mosquito larva found in wetlands to prevent hatching. The small, localized, program is approved for four years from 2016 to 2019.

From April to September, GDG Environnement will apply control agents to the treatment area in and around Kanata North. The control agents are Bacillus Thuringiensis Israelensis (Bti) and Bacillus sphaericus (Bs), which are a bacteria found naturally in soils. No other control agents will be used. The Health Canada Regulatory Agency has approved both agents and has found them to have no effects on humans, birds, fish, animals or other insects. Bti and Bs are effective bacteria that destroy the stomachs of mosquito larvae that hatch in water.
