Markham mixes new and old. Dense condo and townhouse neighbourhoods have grown up around heritage streets. Pests do not care about the age of a building, but the way a building is put together shapes which pests show up.
Pest control in Markham: how we work
We inspect, identify, treat and follow up. In condos and townhouses, we look at shared walls, garbage areas and kitchens, not only the unit you are in.

What pests are common in Markham
- Cockroaches in condos, where they can travel through shared pipes and walls. That is why one unit can be hard to treat alone.
- Ants each spring, as colonies wake up.
- Mice in fall, in both old and new homes.
- Bed bugs in multi-unit buildings and rentals.
Our cockroach control page explains the treatment steps.
Homes in Markham and the pests they tend to see
- Condos and townhouses in areas like Cornell and Markham Centre: cockroaches, ants and bed bugs.
- Unionville and Markham Village: older homes with basements, foundations and rooflines where mice find entry points.
- Towers near the Milliken and Agincourt border: cockroaches and bed bugs.
The Rouge and Don River valleys bring green space close to many neighbourhoods, so wildlife and insects are never far.
Renting in Markham: tenant rights
Ontario’s Residential Tenancies Act says your landlord must keep your unit in a good state of repair. That includes dealing with pests.
York Region Public Health says tenants should speak to their landlord, building owner or property manager first about rodents. In a condo, tell the board and property management.
On bed bugs, York Region says there are no known cases of infectious disease spread through bites. It also says bed bugs can move between apartments through pipes, wiring and shared walls. For tenants, it suggests sealing cracks and gaps and fixing loose switch covers.
If your landlord does not act, the Landlord and Tenant Board can hear the dispute.
Businesses in Markham
Restaurants, offices and warehouses along busy corridors like Highway 7 need dependable pest plans. See our commercial pest control page.

Tips for condo and townhouse living
Living close to your neighbours means you share some pest risks.
- Do not bring in used furniture without checking it closely for bed bugs, especially seams and joints.
- Seal gaps around pipes under sinks and behind toilets.
- Keep food in sealed containers, and take out garbage often.
- Let your property manager know quickly if you see roaches, since sharing the news early helps the whole building.
- Cover or seal outlets and switch plates that are loose or cracked.
If you hear a scratching sound at night, record when and where. This is useful for the inspection step.
