The City of Calgary takes mosquitoes seriously as they are not only a nuisance but they can also pose a medical threat.The City’s mosquito control program aims to improve the quality of life of Calgarians by reducing mosquitoes, while protecting our natural spaces using means considered to have the least impact on the environment.
Late June and early July are the peak periods for mosquito activity in Calgary. The population declines rapidly as fall approaches. The species of mosquito that can carry West Nile virus usually appears in the city in July and August. Calgarians should take precautions to avoid mosquito bites.
- Use a mosquito repellent containing DEET or other approved ingredients on exposed skin; apply it to clothing as well, because mosquitoes may bite through fabric.
- Wear long-sleeved shirts, pants and a hat when outdoors during peak mosquito biting periods (between dusk and dark, roughly 7:00 to10:00 PM in the summer).
- Place mosquito netting over infant carriers when outdoors.
- Repair window and door screens so that mosquitoes cannot get indoors.
Any container that does or can hold water is a potential breeding ground for mosquitoes. Keep water moving in fish ponds with an aerator, and cover or upturn any containers or old tires that could collect water and breed mosquitoes.
