Residential use
The by-law states that residents who use pesticides that contain these banned molecules may face fines.
To protect your health and that of ecosystems, consider safer and more environmentally friendly alternatives. As a last resort, if your problem persists, you can use biopesticides, products made from microorganisms that come from natural sources.
If you are using a professional horticulturist, lawn maintenance specialist or exterminator, make sure that individual or company holds a permit to use authorized pesticides. There is a list (in French) of companies who have a permit.
