A single pest treatment in Scarborough almost always lands between $150 and $450, and which end you hit comes down to the pest and the size of the property. Rodent and bed bug work sits above that: sealing out a mouse problem usually runs $200 to $500, rats start at $300 to $600 and climb, and bed bugs top the list at $300 to $1,200 a room for chemical or $2,000 and up for whole-home heat. What follows is the full pest-by-pest table, the handful of things that actually decide the number, and the moves that keep you from overpaying. We put these ranges in writing because hardly any other Scarborough company will, and you deserve one in hand before you dial.

What pest control costs in Scarborough, by pest
These are GTA-wide market ranges for a residential job, not a quote for yours. Where you actually land depends on how bad it is, the size of the home, and how many visits it takes, all covered further down. Each pest links out to its own page if you want the full plan for that one.
| Pest | Typical Scarborough range | Notes |
|---|---|---|
| General / single treatment | $150 to $450 | Most common one-off jobs land here |
| Mice | $200 to $500 | Trapping plus entry-sealing; sealing drives the price |
| Rats | $300 to $600+ | Burrows and exclusion cost more than mice |
| Cockroaches | $200 to $600 | German roaches in condos usually need 2 to 3 visits |
| Ants | $150 to $300 | Pavement and odorous ants, the nuisance kind |
| Carpenter ants | $250 to $500 | Structural; finding the nest is the work |
| Bed bugs, chemical | $300 to $1,200 per room | Multiple visits; prep matters to the price |
| Bed bugs, whole-home heat | $2,000 to $4,000+ | One treatment, whole unit, highest ticket |
| Wasp / hornet nest | $150 to $400 | Same-day; height and location move it |
| Spiders | $150 to $350 | Often folded into a general perimeter treatment |
| Quarterly / recurring plan | roughly 20% to 40% off per-visit | Per visit, versus booking one-offs |

What actually moves the price
Four things decide where you sit in a range: how severe it is, how big the property is, how hard the pest is to reach, and how many visits it takes. The rest is noise.
- Severity. A few mice slipping into a Woburn back-split in October is nothing like an established colony working the walls and attic. The deeper the pest is dug in, the more product, traps, and labour it takes, and the more return visits before it is truly clear.
- Size and layout. A one-bedroom apartment near Scarborough Town Centre has far less perimeter to treat and fewer gaps to seal than a two-storey detached on a Guildwood lot. Both the square footage and the room count push the number up.
- Access. A wasp nest at ground level beside the patio door is cheaper to clear than one tucked under a third-storey soffit. A basement crawlspace you can stand in beats one you belly-crawl through. Tougher access means more time and sometimes equipment.
- Number of visits. This is the one people overlook. A single ant treatment is one price. German cockroaches or bed bugs call for a series, usually two or three visits about two weeks apart, because the point is to break the breeding cycle, not just knock down what is visible today.
The pest sets the floor of the range; the severity, size, and access set where you land inside it.
One-time treatment versus a recurring plan
Book a one-time treatment when the problem is single and contained: a wasp nest, an early-spring ant trail, one stray mouse. Book a recurring plan only when the pressure never lets up, meaning you back onto a ravine, sit next to a restaurant or a construction site, or have fought the same pest three seasons running. A quarterly plan usually cuts the per-visit cost by 20% to 40% against one-offs, but that saving is only real if you genuinely need the visits.
Most Scarborough homes never need a plan. Plenty of the postwar bungalows and back-splits east of Victoria Park get one seasonal mouse push and nothing more. We will tell you straight when a single job will hold, because signing you up for a year of service you do not need is exactly what this page exists to warn against.
If one treatment will fix it, that is what we book. We would rather hear from you again next year than bill you every quarter for nothing.
The cost of waiting
Waiting is the most expensive move you can make, and the cost stays hidden until the invoice lands. Pests compound: mice breed, roaches multiply, a small wasp nest swells to the size of a football, and bed bugs march room to room. The longer it sits, the more of the home is caught up in it, the more visits it takes, and the higher the total climbs, often 20% to 50% past what the early call would have run.
A handful of mice in a Bendale bungalow in October is a $250 job. Left until February, with attic traffic and half a dozen gnawed entry points, the same problem is $600. One wasp nest caught in June off a Cliffside eaves is $200; a mature August nest of thousands inside a wall void can cost double. German cockroaches spotted in one Kingston Road apartment unit are a two-visit job; ignored for three months across the kitchen, they become a four-visit one. The early call is almost always the cheap call.
What a "free inspection" really is
A free inspection means a licensed technician comes to the property, confirms the pest, locates where it is getting in, and hands you an exact price before any work begins, at no cost and with no obligation. That is the whole of it. It is how a phone range becomes a firm number, and how an honest company earns the job instead of guessing at it.
Now the honest part. At some shops the free inspection is just a foot in the door, and it somehow always turns up a reason for the most expensive plan. A real one can end with the technician saying you do not need us yet and here is what to watch for. If the inspector refuses to leave without a signature that day, you have learned what the visit was really about.
Why Scarborough pricing sits where it does
Scarborough is the east end of the City of Toronto, so the same city-level costs apply here as anywhere in the amalgamated city: labour, insurance, fuel. What sets it apart from the downtown core is the housing. Scarborough is mostly postwar suburban stock, bungalows, back-splits, and side-splits on large lots, many with mature trees and ravine backing, and those older homes hide more entry points to seal than a newer build. Layered on top is a heavy stock of aging rental apartment towers along Kingston Road, Eglinton East, and Lawrence East, where shared walls and pipe chases let cockroaches and bed bugs move building-wide, a harder job than a single detached house. The same mouse job that is $300 in a newer Milliken house can be $400 in an older Wexford bungalow for the sealing alone.
That is the housing, not a markup. It is also why comparing a Scarborough quote to a number your cousin paid in Barrie, on a newer lot with half the entry points, tells you very little.
How to avoid getting overcharged
Get the pest identified before you get quoted, insist on the price in writing, and never sign a plan when a one-time treatment will do. Those three habits shut down most of the overcharging in this market.
- Make them name the pest first. A quote given before an inspection is a guess, and guesses run high to stay safe.
- Get the number in writing before work starts. A verbal "it'll be around" has a habit of creeping up once the technician is on site.
- Ask what the job includes. Follow-up visits, callbacks, and the guarantee belong in the price, not tacked on later as extras.
- Push back on the plan. Ask it plainly: "Will a one-time treatment solve this?" A straight company tells you yes when yes is true.
- Compare within the region. Hold a Scarborough quote against other Scarborough quotes, not against what someone paid in a newer suburb with a driveway and half the entry points.
Cheapest is not the goal; honest and complete is. A $150 treatment that skips the sealing on a mouse job is not a deal, it is a $150 down payment on the same problem next month. Ask what is included before you compare prices.
Common questions
How much does pest control cost in Scarborough?
Most single treatments run $150 to $450. Rodent work runs $200 to $600 depending on how much sealing it needs, and bed bugs top the list at $300 to $1,200 a room for chemical or $2,000 and up for whole-home heat. The table above splits it out pest by pest.
Why won't most companies give me a price over the phone?
Because the real number turns on the pest, the severity, the size of the home, and the access, and those need an inspection to pin down. What a company can do, and what we do, is hand you an honest range over the phone so you are not walking in blind.
Is a one-time treatment enough, or do I need a plan?
For most Scarborough homes and most pests, one treatment plus a follow-up does it. Recurring plans only pull their weight under steady pressure, like a lot backing onto a Highland Creek ravine or a unit next to a restaurant. We tell you which one you are before we book.
Does the price include follow-up visits?
On our residential jobs the follow-up is built into the price, and the two-month guarantee means that if the pest is still active we come back once at no charge. Always confirm what is included before you weigh two quotes against each other.
Why is bed bug treatment so much more expensive?
Bed bugs take either several chemical visits or one whole-home heat treatment that brings the entire unit up to a lethal temperature, which needs specialized equipment. That is why chemical runs $300 to $1,200 a room and heat runs $2,000 and up. The bed bug page covers which one makes sense when.
Will waiting a few weeks really cost more?
Usually, yes. Pests breed and spread, so the job grows while you sit on it, often 20% to 50% more by the time you call. The early call is the cheap call.
Are the products safe for pets and kids at these prices?
Price and safety are unrelated. Everything we apply is registered by Health Canada's Pest Management Regulatory Agency, which weighs the risk to children and pets before a product clears, and we use it strictly to the label. Tell us about pets, kids, or a pregnancy when you book.
Do I even need to pay anyone, or can I handle it myself?
Sometimes you can. A lone spider or a single ant trail is often a do-it-yourself fix. We put together an honest guide to when you need an exterminator and when you do not, because the cheapest job is the one you never had to hire out.
