Reducing the number of mosquitoes in your surroundings is a good way to protect yourself from mosquito bites. Doing this helps prevent the transmission of certain infections, including the West Nile Virus (WNV).
Mosquitoes breed in water. Standing water, or water that is stagnant, is the ideal setting for the reproduction of mosquitoes that may carry WNV. To reduce the number of mosquitoes, eliminate standing water and keep your surroundings clean.
Insecticides destroy insects, their larvae and eggs. In Quebec, it is prohibited to use insecticides that are harmful to humans, animals and the environment. Less toxic insecticides are available and must be used according to manufacturer’s instructions.
When necessary, the ministère de la Santé et des Services sociaux (MSSS) organises widespread insecticide application aimed at reducing the number as insects and preventing transmission of viruses such as West Nile.
Insecticides used in such applications do not negatively affect human health or the environment. There is no need to protect yourself from these insecticides.
Some municipalities conduct insecticide application to improve the quality of life of their citizens. However, these applications do not aim to prevent transmission of viruses.
