The Ontario government’s action plan to combat West Nile virus emphasizes that avoiding mosquito bites is the best way to battle the virus. People can take precautions to avoid mosquito bites by covering up and removing stagnant water around their property. Many municipalities are preparing to carry out activities to control mosquitoes carrying West Nile virus as part of their mandate to protect public health. Public health units will make the decision on what mosquito control activities will be carried out.
Health Canada has registered a number of pesticides used to control mosquitoes. The Ontario Ministry of the Environment for its part regulates the sale, use, transportation, storage and disposal of federally registered pesticides in Ontario under the Pesticides Act and Ontario Regulation 63/09.
