Mosquito Control in Toronto
Toronto’s ravine system, mature tree canopy, and summer humidity create ideal mosquito breeding conditions. The Don Valley, Humber Valley, Taylor Creek, and Highland Creek corridors produce billions of mosquitoes annually — and if your property is within a few hundred metres of these green corridors, your backyard is in the drift zone.
But you don’t need to live near a ravine to have a mosquito problem. Any standing water on your property a clogged gutter, a bird bath, a low spot in the lawn, a forgotten plant saucer is a breeding site. A single female mosquito lays 100–300 eggs in standing water, and those eggs become biting adults in 7–10 days.
Pestisect’s mosquito control combines breeding site elimination with barrier spray treatment to give you your outdoor space back.

Why Mosquito Control
Why Toronto's Mosquito Problem Is Getting Worse
Climate shift
Toronto's summers are warmer and wetter than they were 20 years ago. More rain = more standing water. Higher temperatures = faster mosquito development cycles. The mosquito season that used to run June through August now extends from mid-May through early October in many years.
Urban flooding
Toronto's aging storm water infrastructure means localized flooding after heavy rain. Pooling water in basements, window wells, and low-lying areas creates temporary breeding sites that produce mosquitoes for weeks.
The ravine factor
Toronto's ravine system is one of the city's most valued features — but it's also the city's biggest mosquito factory. The slow-moving pools, marshy edges, and leaf litter along ravine floors produce massive mosquito populations that drift into adjacent residential areas.
Treatment Process
Our Mosquito Treatment Approach
Our mosquito extermination process is designed to eliminate infestations at every stage, from detection to prevention.
Property Assessment and Breeding Site Elimination
We walk your entire property and identify every standing water source and potential breeding site:
- Clogged gutters and downspout extensions
- Bird baths, plant saucers, pet bowls
- Bire swings, toys, and any container that holds water
- Low spots in the lawn where water pools after rain
- French drain endpoints and sump pump discharge areas
We eliminate what we can and advise you on what to address (gutter cleaning, regrading).
Barrier Spray Treatment
We apply a residual barrier spray to vegetation, fence lines, under decks, and along the property perimeter. The spray bonds to leaf surfaces and kills mosquitoes that land on treated areas for 21–30 days.
Where we spray: Shrubs, hedges, garden borders, under-deck areas, fence lines, around patios, and any shaded, sheltered vegetation where mosquitoes rest during the day.
