Pest Control and Extermination in Newmarket, Ontario
Newmarket is a city of approximately 90,000 people in York Region, bordered by Aurora to the south, East Gwillimbury to the north, and the Holland River winding through its western reaches. The city has a distinct two-character housing stock: the older established neighbourhoods clustered around Main Street and the Heritage Downtown, where homes date from the 1950s through the 1980s, and the newer subdivisions that have expanded east and west over the past two decades. Each presents different pest pressures, and we are experienced with both.
Older homes in central Newmarket have aging foundations with accumulated cracks, older pipe penetrations with deteriorated seals, and mature tree canopies that support substantial carpenter ant populations. Newer subdivisions face fall mouse infiltration pressure as the surrounding fields are developed or go dormant each year, and wildlife from the Holland River valley corridor moves into residential areas throughout the year. Whether your property is a 1970s bungalow near Fairy Lake or a newer two-storey in Armitage, our inspection will identify the specific vulnerabilities present and our treatment will address them directly.
Common Pest Problems in Newmarket
Mice Control
Mouse infiltration is one of the most consistent complaints we receive from Newmarket homeowners each fall. The Holland River corridor and adjacent green spaces create a large outdoor mouse population that moves into structures as temperatures drop. Properties near open land — particularly in the western Newmarket neighbourhoods bordering the river — experience earlier entry activity than those in the city's denser residential core.
Our mice control service covers full interior and exterior inspection, targeted interior trapping, tamper-resistant exterior bait stations, and complete structural exclusion with appropriate materials for each identified entry point. We do not leave until every gap is sealed.
Carpenter Ant Control
Carpenter ants are a recurring problem in Newmarket's older residential areas, particularly in properties with mature landscaping, wood mulch near the foundation, or any moisture history in exterior wood. The Holland River corridor supports a significant carpenter ant source population, and properties adjacent to the trail system and river vegetation are at higher risk. Our carpenter ant control service eliminates the full colony — both the satellite inside the structure and the primary colony in nearby landscape or dead wood.
Wasp Nest Removal
Wasps are active in Newmarket from late May through September. Yellow jacket colonies reach their peak population in August and September, when nests contain thousands of insects and present the greatest sting risk. Nests in wall voids and underground are particularly hazardous because homeowners often encounter them before realizing they exist. Our wasp nest removal service is available same-day during peak season.
Wildlife Removal
Raccoons, squirrels, and skunks are all active in Newmarket's residential areas. Properties near the Holland River, Fairy Lake, and the conservation corridors bordering the city experience the highest wildlife pressure. Our wildlife removal team provides humane removal and permanent exclusion with heavy-gauge steel mesh. Learn more about raccoon removal and squirrel removal.
