West Nile Virus in Mississauga & the GTA: Reduce Mosquito Breeding Around Your Home
West Nile virus (WNV) is spread to people through the bite of an infected mosquito. In Ontario, activity rises in summer and often peaks late summer to early fall. The simplest way to lower risk around your home is to eliminate standing water—and one of the most overlooked sources is a clogged eavestrough (gutter).
Why gutters matter
Blocked eavestroughs and downspouts hold small pools of water where mosquitoes lay eggs. Keeping water moving off the roofline helps protect your family and your property.
Quick steps for Mississauga & GTA homeowners
- Keep water mo7ving: repair sagging gutters, clear downspout outlets, and confirm proper slope.
- Reduce debris long-term: install pro-grade gutter guards and larger outlets to prevent recurring clogs.
- Eliminate yard standing water weekly: empty plant saucers, toys, buckets, birdbaths, and cover rain barrels with fine screens.
- Storm drains / catch basins: in Peel (Mississauga, Brampton, Caledon) you can request free larvicide treatment for residential catch basins in season.
- Personal protection: use insect repellent as directed and take extra care at dawn and dusk.
Local monitoring & updates
Toronto Public Health and Peel Public Health monitor WNV by trapping and testing mosquitoes through the summer and by treating municipal catch basins with larvicide. For current advisories in Mississauga, check the City of Mississauga updates.
Know the basics
Most people infected with WNV have no symptoms; some get mild flu-like illness. Preventing bites and removing standing water remain the best protection. Learn more from the Public Health Agency of Canada. If you’re concerned about symptoms, contact a health professional.

FAQ
When is West Nile virus season in Ontario?
Summer through early fall, with most activity typically in August and September. Local public health units issue updates each season.
Do gutter guards really help?
Yes—quality guards reduce leaf buildup so water doesn’t pool along the roofline. We use pro-grade systems designed for GTA weather.
What else can I do on my property?
Dump standing water weekly (planters, toys, tarps, pool covers), keep rain barrels screened, and make sure downspouts discharge away from the foundation.
