Mosquitoes & West Nile Virus in Winnipeg
Winnipeg is consistently ranked among the worst cities in Canada for mosquitoes. The flat landscape, spring flooding, and warm summers create ideal breeding conditions across the city and surrounding region. Manitoba Health monitors West Nile virus activity each summer, and positive cases in mosquito populations are regularly confirmed across the Winnipeg area.
West Nile virus is transmitted through the bite of an infected Culex mosquito. While most people who contract it experience mild or no symptoms, the virus can cause serious neurological illness in some individuals — particularly older adults and those with weakened immune systems. Reducing the mosquito population on your property reduces your family's exposure risk.
When Winnipeg Mosquito Season Peaks
Mosquito populations typically surge in Winnipeg from late May through August, with the highest populations following spring runoff and after rain events. Culex mosquitoes — the primary West Nile virus vector — are most active in mid-summer, feeding at dawn and dusk.
Our Mosquito Control Treatments
- Property Inspection: We identify standing water sources, dense vegetation, shaded resting areas, and other conditions contributing to high mosquito populations on your property.
- Barrier Spray Treatment: We apply a residual insecticide to vegetation, shrubs, fences, and lawn perimeters — areas where adult mosquitoes rest during the day. Treatment significantly reduces adult mosquito populations for 3–4 weeks per application.
- Larval Source Reduction: Where standing water cannot be eliminated (ornamental ponds, low areas, eavestroughs), we apply larvicide to prevent mosquito larvae from developing into biting adults.
- Seasonal Programs: For maximum protection through the full Winnipeg mosquito season, we offer multi-application seasonal programs starting in late May through August.
Residential & Commercial Mosquito Control
We treat residential properties, acreages, commercial properties, restaurants and patios, campgrounds, and special events. If you're planning an outdoor event in Winnipeg or surrounding area, a pre-event barrier spray can dramatically reduce mosquito activity on-site.
