Mosquitoes in Ontario: Identification, Activity & Prevention

Mosquitoes develop wherever water remains long enough for larvae, while adult mosquitoes rest in shaded, sheltered vegetation. In Ontario, activity rises during the warm season and can be especially noticeable near standing water, dense shrubs, and wooded edges. Mosquito Man inspects likely breeding and resting areas, recommends practical source reduction, and applies targeted yard treatments according to the service plan.

Where do mosquitoes breed around Ontario homes?
Mosquito larvae develop in standing water, including overlooked containers, clogged eavestroughs, low spots, and other water-holding areas. The source can be small and easy to miss.
Mosquito activity generally increases during warmer months. Many species are more noticeable around dawn and dusk, though activity varies with species, weather, and local conditions.
Adult mosquitoes often rest in cool, shaded vegetation during the day. Dense foliage and nearby moisture can make parts of a yard more attractive to them.
Empty or refresh water-holding containers, keep eavestroughs clear, and address standing water where practical. Larger or recurring sources may need a closer inspection.
Technicians look for standing water, shaded resting areas, dense vegetation, and other property conditions that may support mosquito activity.
The service plan may combine source-reduction advice with targeted treatment of suitable yard vegetation and harbourage areas. The approach and schedule depend on the property and program.
