West Nile numbers prompt Province-mandated fogging program tomorrow

Released: July 30, 2026 at 5:03 p.m.

Winnipeg, MB – We will begin a targeted fogging program tomorrow in response to high numbers of Culex tarsalis mosquitoes in several areas of Winnipeg.

The Province of Manitoba issued a fogging order under The Environment Act. The Act requires municipalities to fog when the risk of West Nile Virus transmission via Culex tarsalis mosquitoes is high.

Our program will start at 9:30 p.m. tomorrow, July 31. Per the provincial order, buffer zones are not in effect within city limits during this fogging program.

Subject to weather conditions, the program will target the following Insect Management Areas:

  • IMA 22 – Fairfield Park, Richmond West, Waverley West, Waverley Heights, Bison Run, Bridgwater Centre, Bridgwater Forest, Bridgwater Lakes, Bridgwater Trails, Prairie Pointe, South Pointe
  • IMA 23 – Whyte Ridge
  • IMA 24 – Linden Ridge, West Fort Garry Industrial
  • IMA 43 – North Inkster Industrial, Tyndall Park
  • IMA 44 – Burrows - Keewatin, Inkster Industrial Park
  • IMA 48 – Inkster Gardens, Mandalay West, The Maples
  • IMA 51 – Amber Trails, Rosser - Old Kildonan

Residents can see a daily program schedule online and register online for public service announcements. We will release the upcoming schedule at least eight hours in advance.

The program will be carried out using DeltaGard 20EW®.

 West Nile Virus Program

The West Nile Virus Program is a provincial responsibility. Weekly average trap counts of Culex tarsalis by regional health authority are available on the Province of Manitoba’s West Nile virus website.

People can take several measures to protect themselves from West Nile Virus:

  • Reduce mosquito numbers by getting rid of mosquito habitats around your home
  • Reduce the time you spend outdoors between dusk and dawn
    • The peak mosquito hours are around dusk and dawn, but Culex mosquitoes will also bite during the night
  • Wear light-coloured, loose-fitting, long-sleeved tops and pants when outside
  • Apply an appropriate insect repellent, according to Health Canada Guidelines and label instructions
  • Check that door and window screens fit tightly and are free of holes
