Strong Mosquito Season Looms in Ontario and Quebec

As temperatures begin to rise, experts are warning that large parts of Ontario and Quebec could see a sharp increase in mosquito activity in the coming days and weeks, following a cold and wet spring that left behind standing water across many communities.
According to a recent CityNews report, the cool, rainy spring delayed mosquito activity in some areas, but it also created the conditions for a sudden surge once warmer weather moves in. Experts say standing water from rain and melting snow provides the breeding ground mosquitoes need, especially around homes, gardens, small ponds, gutters, flowerpots, and outdoor containers.
The warning does not mean there is a public health emergency. It is, however, an early reminder for families to take simple preventive steps before mosquitoes become a daily nuisance, especially as more people spend time outdoors, in backyards, parks, cottages, and campsites.
The Public Health Agency of Canada says the best way to prevent West Nile virus infection is to avoid mosquito bites and reduce mosquito breeding areas by removing standing water around the home. Public Health Ontario also advises reducing mosquito development sites and using personal protection to lower the risk of exposure.
In Quebec, the provincial government notes that stagnant water, meaning water that does not move or flow, is an ideal breeding ground for mosquitoes that may carry diseases, including West Nile virus and other less common viruses.
Public health guidance recommends emptying or drying water collected in flowerpots, garbage lids, birdbaths, children’s toys, gutters, tires, and open containers. Residents are also advised to wear clothing that covers exposed skin when outdoors in the evening or near wooded and wet areas, and to use insect repellent approved for use in Canada, especially for children, older adults, and people spending long hours outside.
Ontario also tracks mosquito-borne disease activity during the season. Public Health Ontario says mosquito data is updated weekly during the mosquito season, which typically runs from May to October.
Mosquitoes are a normal part of summer in Canada, but the combination of a wet spring and sudden warmth could make the start of this season more noticeable in some areas. A quick cleanup around the home this week may help families avoid a much bigger problem as summer approaches.
