Typical Cost in Oshawa
$150–$500
Final cost depends on severity, property size, and treatment method.
Oshawa is Durham Region's largest city and a centre of industrial heritage, with housing stock ranging from early 20th-century brick homes in the downtown core to modern subdivisions in Windfields and Samac. The Oshawa Creek ravine system runs through the heart of the city, serving as a wildlife corridor that delivers raccoons, skunks, and squirrels into residential neighbourhoods. Older homes in Taunton and the McLaughlin corridor face chronic mouse entry through aging foundations and crumbling mortar joints, while multi-unit buildings downtown contend with cockroach and bed bug issues. The city's proximity to Lake Ontario adds waterfront pest pressures along the harbour area. PestRecord connects Oshawa residents with licensed pest control professionals.
Our Mosquito Control Process in Oshawa
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 Oshawa
-
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.
