West Nile virus

West Nile virus is established in Ontario and the disease is transmitted to humans by mosquitoes. There is no way to predict how serious West Nile virus will be in any given year.

It's important you take steps that will protect you and your family from mosquito bites. The good news is, it's easy.


Use insect repellent when outdoors


Always read the label directions for use.

If they can't get to you, you won't get bitten


Clean up and ruin a mosquito's love life


It's important to get rid of standing water around your home on a regular basis – once a week is a good standard. Adult mosquitoes like to rest in dense shrubbery. Keep bushes and shrubs clear of overgrowth and debris. And keep your compost pile turned on a regular basis.
