West Nile Virus

West Nile Virus (WNV) is spread by mosquitoes. Humans can become infected if they are bitten by an infected mosquito. It is important to remember that not all mosquitoes are infected, but you should still protect yourself by wearing long-sleeved shirts, long pants, socks and shoes when outdoors in the evening or early morning, and using an insect repellent that contains DEET.

For more information on the virus, symptoms, and mosquito control and surveillance programs, visit the Halton Region site. You can also call the West Nile Virus Info Line at 905-825-6187, or toll free at 1-866-442-5866 or TTY at 905-827-9833; or email wnv@halton.ca.

Health questions related to WNV should be directed to Halton Region Health department at 905-825-6060.

Reducing standing and stagnant water

Mosquitos like to breed in stagnant water, so by limiting standing, stagnant water, the town can decrease the number of mosquito breeding areas and the probability of WNV.  

You can help by reporting standing, stagnant water on town or private property. Contact the town at 905-845-6601 ext. 3006.

Reduce or eliminate all stagnant and standing water sites around your home and garden including:

  • Unopened pools
  • Ponds that are not aerated 
  • Birdbaths
  • Upright wheel barrels or pails 
  • Spare tires 
  • Rain barrels without a mosquito screen 
  • Clogged eaves troughs 
  • Children's toys  

What if I find a dead bird in my backyard?

The Halton Region Health department's WNV dead bird surveillance program has been discontinued. If you find a dead bird on private property, please put on gloves and dispose of the bird safely by placing it in a securely closed double-lined plastic bag in your garbage.

If you find a large dead bird, you can choose to call the Canadian Cooperative Wildlife Heath Centre (CCWHC) at 1-866-673-4781 to have the bird tested for WNV.
