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).
Things to Do
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.
Eliminate Standing Water
- Remove or empty buckets, barrels or all other outdoor objects that may contain water, like old tires for instance
- Remove water that accumulates on pool covers
- Clean the gutters of your house
Keep your Surroundings Clean
- Cover garbage cans
- Maintain your pool. The circulating water of a proper filtration system prevents mosquitoes from breeding there
- Install a mosquito net on your rainwater reservoir
- Change the water in your bird drinking trough regularly
- Add fish that eat mosquito larvae in your ornamental pond
Use of Insecticides
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.
Application of Insecticides
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.
