Pestisect Pest Control

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.

Seasonal Programs

One treatment helps. Monthly treatments from May through September provide season-long protection. Most Toronto clients on our seasonal program report 80–90% reduction in backyard mosquito activity.

Toronto Mosquito Hotspots

🚫

Ravine-adjacent properties

Homes along the Don Valley, Humber River, Taylor Creek, and Highland Creek corridors see the highest mosquito pressure. Barrier spray is most effective for these properties.

🌿

Older neighbourhoods with mature trees

The Annex, Rosedale, Forest Hill, and Beach neighbourhoods have dense tree canopy that provides shade and moisture — both of which mosquitoes prefer.

🪟

Waterfront

Properties near Toronto Islands ferry terminal, Cherry Beach, and the Harbourfront see lake-driven mosquito pressure, especially in humid conditions.

Frequently Asked Questions

When is mosquito season in Toronto?
Mid-May through early October in most years. Peak activity is June through August. Warm, wet springs extend the season. First hard frost ends it.
Toronto Public Health monitors for West Nile Virus annually. Positive mosquito pools are found in Toronto every year. While human cases are uncommon, the risk is real — particularly for elderly residents and those with compromised immune systems. Reducing mosquito populations around your home reduces exposure.
21–30 days depending on weather. Heavy rain accelerates breakdown. Monthly treatments maintain consistent protection through the season.
The products we use are applied to vegetation where mosquitoes rest — not to flowers, food gardens, or water features. Applied correctly, the risk to pollinators is minimal. Pets should stay off treated surfaces until dry (typically 30 minutes). We can avoid specific areas on request.
Mosquitoes can fly 1–3 km from their breeding site. If your Toronto property is near a ravine, creek, or any large-scale water source, mosquitoes drift in from elsewhere. Barrier spray kills them when they land on your property — it doesn’t prevent them from arriving, but it prevents them from staying.
