Protecting Halton from West Nile virus

To help keep West Nile virus (WNV) out of our communities, Halton Region has begun its West Nile virus prevention program. Whether by monitoring and reducing the amount of mosquitoes in Halton or helping our residents make smart choices to prevent West Nile virus, together we can help keep Halton safe and healthy this summer.

Since West Nile virus is spread by mosquitoes, Halton Region is diligent in monitoring and preventing mosquito larvae from hatching to help keep WNV out of Halton. As a result of the relatively dry spring, the Halton Region Health Department has found higher numbers of mosquito larvae in catch basins and other places with standing water. To help control the mosquito population and reduce the threat of West Nile virus, the Health Department has started treating areas of standing water with a larvicide to prevent the mosquito larva from maturing into hungry adult mosquitoes.

Health Department staff also set mosquito monitoring traps throughout Halton Region to determine the level of WNV risk. The number and types of mosquitoes are examined and sent for WNV testing.

While Halton works behind the scenes to reduce the chance of WNV in Halton, you can also help protect yourself and continue to enjoy the warm weather this summer.

The most important step to preventing West Nile virus it to prevent mosquito bites and a few simple actions can make all the difference.

  1. Wear insect repellent with DEET or Icaridin.
  2. Avoid being outdoors at dusk and dawn.
  3. Cover up: wear light coloured clothing that covers your arms and legs.
  4. Remove areas of standing water from your home. Mosquitoes lay their eggs in water that does not flow.

If you notice any areas of standing water on public property that can’t be drained or removed, please report it to the Health Department and they can determine if larviciding is necessary.

Working together, we can enjoy a safe and healthy summer and keep Halton a great place to live, work, raise a family and retire.
