Why Bed Bug Infestations Are Common in Markham
International Travel and High-Tech Workforce
Markham hosts one of Canada's largest concentrations of technology companies, with employees travelling frequently to international destinations including Asia, Europe, and the United States. Business travel is a primary introduction route for bed bugs, which can hitchhike in luggage, clothing, and laptop bags. A single return trip from an infested hotel is sufficient to introduce bed bugs to a Markham home. The Markham technology corridor at Highway 7 and Warden supports a workforce with above-average international travel frequency.
Milliken Mills Multi-Unit Spread
The high-density residential towers in Milliken Mills near the Scarborough-Markham boundary are among the highest-risk properties in York Region for bed bug introduction and spread. Shared laundry facilities, elevators, and hallway furniture provide secondary transmission routes in addition to wall void travel. Buildings with more than 100 units and high tenant turnover create conditions where a new introduction occurs faster than the previous infestation is fully resolved, creating a persistent building-level problem.
Cornell Townhome Connected Structures
Cornell's rows of attached townhomes share party walls from basement to attic, with continuous conduit runs for utilities connecting the entire row. Bed bugs entering one unit from secondhand furniture, a visiting guest, or purchased goods from an infested source can spread to adjacent units in 2–4 weeks through these shared structural pathways. Because the housing is new, many Cornell homeowners have not encountered bed bugs before and are unfamiliar with the early signs, delaying treatment and allowing the infestation to grow.
Unionville Secondhand Furniture Risk
Unionville's vibrant community of estate sales, antique markets, and neighbourhood Facebook Marketplace transactions creates consistent exposure to secondhand upholstered furniture — the most common non-travel introduction route for bed bugs. Beds, sofas, and upholstered chairs sourced from unknown origins carry a meaningful risk of harbouring bed bugs or their eggs. We recommend a professional inspection of any secondhand upholstered furniture before bringing it into your home.
Bed Bug Treatment Methods We Use in Markham
Heat Treatment
We use industrial heat equipment to raise the entire room to 50–56°C and maintain that temperature for 60–90 minutes. This kills all bed bugs and their eggs in a single visit without any residual chemicals. Heat penetrates mattress cores, wall voids, and baseboards — areas that chemical treatments can miss. Heat treatment is ideal for Cornell townhomes and Unionville single-family homes where residents can vacate for 4–6 hours. We protect heat-sensitive electronics and candles prior to treatment.
- Kills all life stages in one visit
- No residual chemicals
- Can return same day after cooling
Chemical Treatment
We apply a combination of a fast-acting contact pesticide and a residual product with 60–90 day activity to all identified harborage sites: mattress seams, box springs, headboards, baseboards, and nearby wall voids. Chemical treatment is preferred for Milliken Mills condos where heat treatment logistics are more complex, and for situations where only one room requires treatment. A follow-up visit at 2–3 weeks confirms that hatching eggs have been eliminated by the residual product.
- No specialized equipment logistics
- Residual protection for 60–90 days
- Ideal for condo and apartment units

What Markham Homeowners Say
"Our condo building had a known bed bug issue on our floor. Bugsway coordinated with our property manager, inspected three units, and treated all of them on the same day. The follow-up visit three weeks later confirmed complete elimination. Very professional and discreet service."
Angela W.
Milliken Mills, Markham
"We brought in a secondhand sofa and within three weeks discovered bed bugs in the master bedroom. Bugsway used heat treatment and the problem was completely resolved after one visit. They also inspected the adjacent party wall to confirm the bugs had not spread to our neighbours."
David H.
Cornell, Markham
"We noticed bites after returning from a business trip to Singapore. Bugsway came the next day, confirmed the infestation in the master bedroom, and scheduled heat treatment within 48 hours. Excellent response time and the treatment was completely effective."

Bed Bug Risk in Markham's Diverse Communities
Markham's position as one of Canada's most diverse cities means significant international travel activity, increasing bed bug introduction risk throughout all communities. Unionville and Cornell's dense condo towers and rental apartments have a higher transmission risk than detached home communities, as shared hallways, elevators, and laundry rooms provide vectors for bed bug movement between units. Markham residents returning from travel through Pearson International or purchasing used furniture through Facebook Marketplace should inspect items thoroughly before bringing them indoors.
Shared laundry facilities in Milliken's high-rise corridor along Kennedy Road and Steeles Avenue are a common transmission point — bed bugs can transfer between items in laundry carts and on folding tables. Residents of Cathedraltown, Greensborough, and Wismer in single-family homes are not immune, as secondary purchase markets and visiting guests introduce bed bugs to all housing types across Markham.
Bed Bug Treatment Pricing in Markham
Chemical bed bug treatment for a Markham one-bedroom unit costs $300–$500 for a 2–3 visit program using residual insecticide and insect growth regulator applications. Heat treatment averages $800–$1,400 depending on unit size and access requirements, and eliminates all life stages in a single day-long treatment. Landlords managing rental properties in Milliken or Cornell's apartment corridors should request commercial pricing for multi-unit programs — treating adjacent units simultaneously prevents reintroduction between treated and untreated suites.
All Bugsway Markham bed bug treatments include a post-treatment inspection and 30-day follow-up to confirm elimination. Contact us for a same-day assessment and to discuss whether chemical or heat treatment is the right choice for your Markham property.
