Pest Control in Markham

Markham's Local Pest and Wildlife Specialists

Markham is one of our busiest service areas — a large, diverse city with everything from the 19th-century homes along historic Main Street Unionville to dense new condo towers near Highway 7. That range means our technicians handle a genuinely wide mix of jobs: bed bug treatments in multi-unit buildings uptown, wildlife exclusion on properties backing onto the Rouge River and Rouge National Urban Park, and standard seasonal pest control everywhere in between. We staff enough local capacity to offer same-day service across all of it.

Why Markham Homes and Buildings Get the Pests They Do

Markham Village and Unionville's heritage districts are home to century homes dating to the mid-1800s, many sitting right along the Rouge River. That age and proximity to water gives mice and rats easy entry points through old foundations, and the river corridor itself brings in raccoons and other wildlife.

A few kilometres north, the Uptown Markham and Highway 7 corridor is one of the densest new-condo clusters in York Region, built up rapidly over the past two decades. That density means bed bugs and cockroaches travel between units through shared walls and plumbing, so a problem rarely stays contained to one unit for long.

Out in Cornell, a master-planned community in southeast Markham, newer homes back directly onto Rouge National Urban Park — Canada's first national urban park. That green space gives raccoons and squirrels a direct route into attics and yards, even in brand-new construction.

We've worked all of it, from a century home near Main Street Unionville to a high-rise off Highway 7 to a new build in Cornell. Every property type has its own weak points, and knowing where to look first is most of the job.

The Pests We Get Called For Most

Bed bugs and cockroaches: constant in the Uptown Markham and Highway 7 condo corridor. They spread between units through wall voids and shared plumbing, so treating one unit while the building goes unaddressed rarely holds. We check how far an infestation has actually spread before we start, and we work directly with property managers when a building-wide approach is needed.

Mice and rats: most common in the century homes of Markham Village and Unionville, where decades of settling along the Rouge River have opened up foundation gaps. A mouse needs only a gap the width of a pencil.

Raccoons and squirrels: a regular call in Cornell and other properties backing onto Rouge National Urban Park, where the green space gives wildlife an easy route into attics and backyards. We remove them humanely with one-way doors and seal the entry points behind them.

Wasps and hornets: a summer issue across the city, particularly around the Main Street festivals and outdoor patios in Unionville and Markham Village.

We also handle the smaller stuff that turns up constantly: ants, spiders, silverfish, and centipedes. Not sure what you're looking at? Send us a photo and we'll identify it.

How We Handle a Pest Problem, Step by Step

• Inspection: we identify the pest, work out how far it's spread, and find the entry points. In Uptown Markham's condo towers, that includes checking whether neighbouring units are involved.
• Treatment plan: you get a clear plan and a price before we start. No fees appearing at the end.
• Treatment: eco-friendly, pet-safe products, applied only where the job needs them.
• Sealing and prevention: we seal the gaps, whether that's a Unionville century home's foundation or a shed line near Rouge National Urban Park.
• Follow-up: we check back to confirm it's gone, backed by our money-back guarantee.

Pest Control for Apartments and Condos

A large share of Markham's recent growth has been in the Uptown Markham and Highway 7 condo corridor, and pests behave differently there. Bed bugs, cockroaches, and mice move between units through wall voids, plumbing chases, and outlets, so treating one unit in isolation often isn't enough. We inspect properly, tell you honestly whether the problem is contained to your unit or whether the building needs to be involved, and we work with tenants, owners, condo boards, and property managers alike. Our vehicles are unmarked, which matters in a building where you'd rather not advertise the visit.

Commercial Pest Control for Markham Businesses

We work with shops and restaurants along Main Street Unionville and Main Street Markham, offices and retail near the Highway 7 corridor, and properties throughout Markham's business parks. For food businesses a pest issue is an inspection risk as much as a nuisance, so we work discreetly, document what we do, and schedule around your hours where we can.

Markham Pest Control FAQs

I live in a condo near Highway 7. Can you still treat my unit?

Yes, and we do it constantly given how dense that corridor has become. The key thing to understand is that bed bugs, cockroaches, and mice travel between units through shared walls and outlets, so treating your unit alone sometimes isn't enough. We'll inspect and tell you honestly whether it's contained to your unit or whether the building needs to be looped in.

Why do homes in Unionville and Markham Village get more rodent activity?

Those neighbourhoods' century homes date to the mid-1800s and sit close to the Rouge River. Decades of settling have opened up foundation gaps that mice and rats use to get inside — a more constant issue than the seasonal wildlife pressure newer areas see.

Why do Cornell homes see more wildlife than other parts of Markham?

Cornell backs directly onto Rouge National Urban Park, Canada's first national urban park. That green space gives raccoons and squirrels an easy route into attics and yards, even in brand-new construction.

How fast can you get to me in Markham?

Most days we can be out same-day if you call in the morning. Urgent jobs jump the queue — a wasp nest by a doorway, an animal loose inside the house, or rodents in the kitchen.
