West Nile Virus Found in Mississauga mosquitoes: what you need to know

West Nile virus has been confirmed in Peel Region, with infected mosquitoes detected near Airport and Derry roads in Mississauga. With the virus now active locally, residents are advised to take immediate steps to protect themselves (and their property) from infected insects.

What is West Nile virus?

West Nile virus is a mosquito-borne illness that can cause mild flu-like symptoms in most people, but in rare cases, it can lead to serious illness affecting the brain or nervous system. There is no vaccine or specific treatment for humans, making prevention essential. People over 50 or with weakened immune systems are at higher risk for serious complications.

Tips to protect yourself from mosquito bites

Mosquitoes that transmit West Nile virus are most active at dusk and dawn. Limit exposure during peak mosquito hours or, if possible, stay indoors during these times.

Applying effective insect repellents containing DEET or icaridin when outdoors is also recommended. Other tips include:

• Wearing long sleeves, pants, socks, and a hat.

• Choosing light-coloured, loose-fitting clothing, as mosquitoes are attracted to dark colours.

• Using permethrin-treated clothing or camping gear when outdoors for extended periods.

How to mosquito-proof your property

Mosquitoes lay eggs in stagnant water, turning even tiny amounts into breeding sites. While Peel Region operates a larvicide program, residents can help reduce risk by eliminating standing water on their property.

Empty and scrub water containers at least once a week, including:

• Birdbaths

• Flowerpots and saucers

• Kiddie pools and toys

• Old tires

• Outdoor pet bowls

Other preventive measures include:

• Checking and repairing window and door screens.

• Storing water-catching items indoors or under cover.

• Fixing leaky outdoor faucets to prevent puddles.

• Reporting standing water in public areas to Peel Public Health at 905-799-7700 or 1-888-919-7800, or online.

While the overall risk of contracting West Nile virus remains low, it increases during the summer as mosquito counts rise. Taking these precautions can help protect you, your family, and your community.
