Final cost depends on severity, property size, and treatment method.
Toronto has more raccoons per square kilometre than any city in North America. That is not a guess — biologists have been tracking them for decades. The Don Valley ravine system runs from the waterfront up through Leaside and into North York, and it functions as a raccoon highway delivering wildlife directly into residential backyards. In the Annex, raccoons den in the attics of 120-year-old Victorians where the original soffits have never been replaced. In Parkdale, mice pour into century semis through crumbling mortar joints every October. In Liberty Village and CityPlace, bed bugs move between condo units through shared plumbing risers faster than property managers can respond. Every Toronto neighbourhood has its own pest profile, shaped by housing age, tree canopy, and how close you are to a ravine.
Our Mosquito Control Process in Toronto
Inspection
The technician inspects the property for all mosquito breeding sources: clogged eavestroughs, plant saucers, tarps, wheelbarrows, bird baths, pond edges, low spots in the lawn, and catch basins. Every source found is treated with larvicide or flagged for drainage.
Treatment
Bti granules or briquettes are applied to standing water that cannot be drained: catch basins, ponds, decorative water features, and low areas. A residual insecticide is applied to vegetation, shrubbery, and shaded areas around the property perimeter where adult mosquitoes rest during the day.
Prevention
Treatments are scheduled every 4 weeks during mosquito season (May–September). Each treatment reduces the active mosquito population for 3–4 weeks. Starting in May, before the first generation establishes, is the most cost-effective approach.

Why Hire a Professional in Toronto
-
DIY mosquito foggers treat the air, not the source. Mosquitoes return within hours when the fog dissipates. Professional larvicide treatment addresses the actual breeding population.
-
GTA properties near ravine systems have continuous mosquito pressure from natural breeding sites on public land. A professional treats the private property sources that homeowners miss.
-
Barrier treatments by professionals use products with longer residual effect than retail alternatives, lasting 3–4 weeks instead of hours.
-
Culex mosquitoes, the most common GTA species, can carry West Nile Virus. While the risk in Ontario is low, reducing mosquito populations is the only effective prevention.
-
Professional mosquito programs include catch basin treatment, the single most effective intervention for reducing urban mosquito populations in the GTA.
