Markham Pest Control Services

Markham’s pest issues change depending on whether you are in a historic village district, a newer subdivision, near a ravine corridor, or close to one of the city’s busy commercial areas. In Unionville, Markham Village, Thornhill, Buttonville, Raymerville, Bullock, and older streets around Main Street Markham and Main Street Unionville, mature trees, heritage homes, older foundations, detached garages, basements, laneways, restaurants, and long-established storefronts can create entry points for mice, rats, carpenter ants, pavement ants, cockroaches, spiders, wasps, flies, and overwintering insects.

In newer and growing communities like Cornell, Greensborough, Wismer, Berczy, Box Grove, Angus Glen, Cachet, Victoria Square, Cathedraltown, and Upper Unionville, pest issues often come from tight lot spacing, active construction, backyard decks, finished basements, new landscaping, stormwater areas, and homes near parks or trails. Properties around Toogood Pond, Milne Dam Conservation Park, the Rouge River, Rouge Valley Trail, German Mills Creek, and local green corridors may see more seasonal movement from rodents, ticks, mosquitoes, ants, earwigs, and occasional wildlife.

Commercial areas near Highway 7, Warden Avenue, Woodbine Avenue, Markham Road, Steeles Avenue, 14th Avenue, 16th Avenue, Birchmount Road, Kennedy Road, and the 404/407 corridors can face added pest pressure from restaurants, plazas, offices, warehouses, loading areas, high-rise buildings, and daily traffic.
