Why Markham Homes Need Specialized Pest Control
Markham is a city of contrasts — heritage conservation areas in Unionville and Markham Village sit alongside some of York Region’s newest master-planned communities in Cornell, Berczy, and Cathedraltown. This mix of old and new housing produces a wide range of pest challenges. In Unionville’s historic core, century-old homes with original wooden frames, fieldstone foundations, and mature trees are prime targets for carpenter ants. Large hardwoods overhanging rooflines create moisture bridges that carpenter ants follow directly into fascia, soffits, and structural members.
Markham Village faces similar issues, with its tree-canopied streets and character homes providing ideal conditions for both carpenter ants and wildlife. Raccoons and squirrels den in attics of older homes where soffits have deteriorated or roof vents lack proper screening. These heritage areas see consistent wildlife calls from March through November.
In contrast, Markham’s newer communities deal primarily with rodents. Cornell, Berczy, and Cathedraltown were developed on former farmland, and displaced field mice infiltrate new homes through construction gaps around pipes, wiring, and HVAC penetrations. Our Markham technicians are equally comfortable treating carpenter ant infestations in 150-year-old Unionville homes and performing rodent exclusion on recently built properties in Cathedraltown.

→Markham Pest Control FAQ
Markham has extensive tree cover, particularly in established neighbourhoods like Unionville, Markham Village, and Angus Glen. Mature hardwood trees harbour carpenter ant parent colonies, and the ants establish satellite nests in nearby homes through overhanging branches, moisture-damaged wood, and gaps around windows. Heritage homes in Unionville and Markham Village with original wooden framing are especially vulnerable to carpenter ant damage.
Yes. Newer subdivisions in Cornell, Berczy, and Cathedraltown are built on former agricultural land, which displaces field mice that then seek shelter in new construction. Common entry points include gaps around utility penetrations, garage door seals, and exhaust vents. We recommend a rodent exclusion inspection within the first year of occupancy for any new Markham home to seal these vulnerable points before mice find them.
