You’re sitting there with mice in your walls, or bed bugs in your mattress, or wasps building a nest above your front door. And the first question isn’t “how does treatment work?” — it’s “how much is this going to cost me?”
Fair question. Pest control pricing in Ontario can feel like a mystery. Some companies won’t quote over the phone. Others list ranges so wide they’re useless. So here’s what you’ll actually pay in the Greater Toronto Area in 2026, broken down by pest type, with no sales pitch buried inside.
What Affects Pest Control Cost in Ontario?
Before we get into specific numbers, three things determine what you’ll pay:
1. The pest.
Bed bugs cost more than ants. Structural carpenter ant jobs cost more than pavement ants. Rodents with multiple entry points cost more than a single mouse that wandered in through an open garage door.
2. The size of the problem.
One wasp nest on your eaves? $150-200. Three nests, including one inside your attic? $400+. A single mouse caught in a trap? $200-300 for inspection and exclusion. A full-blown infestation with droppings in every room? $600+.
3. Your property.
A 1,200 sq ft bungalow in Brampton costs less to treat than a 3,000 sq ft detached home in Vaughan. Condos and apartments sometimes cost more because of building access restrictions and the risk of reinfestation from neighboring units.
Now let’s break it down by pest.
Bed Bug Treatment Cost: $300-800 Per Room
This is the most expensive common pest treatment in Ontario, and for good reason — bed bugs are incredibly hard to eliminate.
Heat treatment: $300-800 per room
A crew brings in industrial heaters and raises the room temperature to 50-55°C (hot enough to kill all life stages of bed bugs). This is the most effective single-visit treatment, but it’s labor-intensive and requires specialized equipment.
Chemical treatment: $200-400 per room
A licensed exterminator applies residual insecticides to cracks, baseboards, bed frames, and other hiding spots. This usually requires 2-3 visits spaced two weeks apart to catch newly hatched bugs.
Whole-home treatment: $1,500-3,000+
If bed bugs have spread to multiple bedrooms, living areas, and furniture, you’re looking at a whole-home treatment. Heat is faster but more expensive upfront. Chemical is cheaper per visit but costs add up over multiple treatments.
Why so expensive? Bed bugs are resistant to most over-the-counter pesticides, hide in cracks the width of a credit card, and can survive months without feeding. A half-done treatment just creates resistant survivors. You need someone who knows what they’re doing.

Rodent Control Cost: $200-600
Mice and rats don’t just need to be trapped — you need to figure out how they’re getting in and seal those entry points, or you’ll be trapping mice forever.
Inspection + initial treatment: $200-350
This includes identifying entry points, setting snap traps or bait stations, and an initial exclusion plan (sealing gaps, installing door sweeps, etc.).
Full exclusion service: $400-600
For homes with multiple entry points — gaps around pipes, foundation cracks, roof vents without screens — you’re paying for materials and labor to seal the building. This is the only permanent solution.
Follow-up visits: $100-150 each
Rodent control almost always needs 2-3 follow-up visits over 2-4 weeks to check traps, remove dead mice, and confirm no new activity.
Toronto and Mississauga see a surge in mouse calls every October and November when temperatures drop. If you’re hearing scratching in your walls at night, don’t wait — the problem gets worse fast.

Cockroach Treatment Cost: $150-350
Cockroach pricing depends on the species. German cockroaches (the small tan ones you see in kitchens) are harder to eliminate than the occasional large American cockroach that wanders in from outside.
German cockroach treatment: $250-350
These reproduce incredibly fast — a single female can produce 300,000 offspring in a year. Treatment involves gel bait, insect growth regulators, and crack-and-crevice spraying. Expect 2-3 visits over 4-6 weeks.
American cockroach / occasional invaders: $150-250
If you’re seeing the occasional large cockroach (usually coming from drains, sewers, or basements), treatment is simpler — bait, perimeter spray, and exclusion.
Condo/apartment buildings: Add $50-100
Cockroaches move between units through shared walls, plumbing, and vents. If your neighbors don’t treat, reinfestation is likely. Some companies charge extra for multi-unit coordination.

Ant Extermination Cost: $150-400
Not all ant problems are equal. Pavement ants on your driveway? Easy fix. Carpenter ants chewing through your roof beams? That’s structural.
Pavement ants / odorous house ants: $150-250
These are the small black ants you see trailing across your kitchen counter in spring. Treatment is usually a one-time perimeter spray + bait stations.
Carpenter ants: $250-400+
Carpenter ants don’t eat wood — they excavate it to build nests. If you’re seeing large black ants (especially near windows, doors, or in your attic), you’ve got a structural problem. Treatment includes locating the nest (often inside walls or roof voids), insecticidal dust, and exterior perimeter treatment.
Spring is ant season in Ontario. Every April and May, we get calls from Vaughan, Richmond Hill, and Markham — new subdivisions near wooded areas get hit hardest.

Wasp Nest Removal Cost: $150-400
Wasp nest pricing depends on location and size.
Ground-level nest (eaves, porch, shed): $150-250
If we can reach it with a ladder and treat it safely, this is a quick job.
High or hard-to-reach nest (second floor, inside attic, in a tree): $250-400
Nests inside walls or attics require more time, protective gear, and sometimes cutting into drywall to remove the nest completely after treatment.
Multiple nests: Add $100-150 per additional nest
If you’ve got yellow jackets in your garden shed and paper wasps on your garage, we’ll treat both, but each nest is a separate job.
Peak season is July through September. If you’ve got a wasp nest near your front door, don’t wait — they get more aggressive as the colony grows.

General Pest Inspection: $100-200
Not sure what you’re dealing with? Most pest control companies (including us) charge $100-200 for a full property inspection. We identify the pest, find entry points, assess the severity, and give you a treatment plan with upfront pricing.
Inspection fee waived if you proceed with treatment the same day — that’s standard across the GTA.
What You’re Really Paying For
Pest control isn’t just someone showing up with a spray can. Here’s what’s included in a professional treatment:
- Licensed applicators. In Ontario, anyone applying commercial pesticides needs a license from the Ministry of Environment. That training costs time and money.
- Commercial-grade products. The stuff we use isn’t available at Home Depot. It’s stronger, lasts longer, and actually works on resistant pests.
- Liability insurance. If something goes wrong — a chemical reaction, property damage, a customer slips on our equipment — we’re covered. Unlicensed operators aren’t.
- Knowledge. We know the difference between a Norway rat and a roof rat. We know where carpenter ants nest in a Brampton split-level built in 1985. We’ve seen every pest problem the GTA can throw at us.
You’re paying for the job to be done right the first time.
Is Cheaper Pest Control Worth It?
You’ll see Facebook ads and Kijiji posts offering pest control for half these prices. Here’s the reality: cheap treatments either don’t work, or they work temporarily and the problem comes back in a month.
Bed bug heat treatment done wrong (not hot enough, not long enough) kills some bugs but leaves eggs behind. You’re back to square one, except now you’re out $500 and still have bed bugs.
Rodent control without exclusion means you’re paying someone to trap mice forever — because new mice keep coming in through the same holes.
If a quote seems suspiciously low, ask:
- Are they licensed in Ontario?
- Do they carry liability insurance?
- What’s included in follow-up visits?
- What’s their guarantee?
We’ve cleaned up after a lot of cheap treatments that didn’t work. You end up paying twice.
Do Pest Control Companies Offer Payment Plans?
Some do. For expensive jobs (whole-home bed bug treatment, major rodent exclusion, multi-pest packages), some companies offer payment plans or financing.
We keep it simple: upfront pricing, no hidden fees, and if the job requires multiple visits, we’ll tell you that before we start.
GTA Pricing: Is Downtown Toronto More Expensive?
Not by much. Pest control pricing is fairly consistent across Toronto, Brampton, Mississauga, Vaughan, Scarborough, and the rest of the GTA.
You might see slightly higher rates for downtown Toronto condos — not because of the neighborhood, but because high-rise buildings add complexity. Elevator access, building management approval, treating one unit in a 30-floor building where pests can move freely between units — that adds time and difficulty.
But for a typical single-family home? Pricing is the same whether you’re in Etobicoke or Pickering.
FAQ: Pest Control Pricing in Ontario
How much does a pest control inspection cost in Ontario?
A basic pest inspection costs $100-200 in the GTA. Many companies, including us, waive the inspection fee if you proceed with treatment the same day.
Why does bed bug treatment cost more than other pests?
Bed bugs require multiple treatment methods (heat or chemical) and often need follow-up visits. They’re also harder to eliminate completely, which is why treatment costs $300-800 per room.
Do I need to pay for follow-up visits?
It depends on the pest and treatment method. Rodent control and German cockroach treatment usually include 1-2 follow-up visits. Heat treatment for bed bugs is typically one-and-done.
Is pest control more expensive in Toronto than other GTA cities?
Prices are fairly consistent across the GTA. You might see slightly higher rates in downtown Toronto due to building access challenges (condos, apartments), but most companies charge the same in Brampton, Vaughan, or Mississauga.
Can I negotiate pest control pricing?
Some companies offer package deals if you have multiple pest issues or need seasonal service. But be wary of prices that seem too good — cheap treatments often mean shortcuts, and you’ll end up paying twice.
What to Do Next
If you’re dealing with a pest problem right now, here’s what we recommend:
- Get an inspection. Don’t guess. A proper inspection tells you exactly what you’re dealing with and what it’ll cost to fix.
- Get quotes from 2-3 licensed companies. Compare not just price, but what’s included, how many visits, and what’s guaranteed.
- Ask about follow-up. If the company doesn’t mention follow-up visits for rodents or cockroaches, that’s a red flag.
We do same-day service across the GTA. If you’ve got bed bugs in your Scarborough apartment, mice in your Mississauga basement, or wasps building a nest on your Vaughan porch, we’ll give you an honest quote and show up today.
No mystery pricing. No upsells. Just transparent costs and effective treatment.
