Pest Control Cost in Toronto (2026): If You Rent, You Probably Should Not Be Paying
Treatment runs $200 to $900. In a rental, that bill belongs to the landlord almost every time — and it cannot be moved by a lease clause.
In short
A standard single treatment in Toronto costs $200 to $450. By pest: mice about $200 to $500, cockroaches $200 to $600, and bed bugs $300 to $900 for a chemical programme or $1,000 to $3,000 for heat treatment.
If you rent, stop before you pay any of it. Under Ontario’s Residential Tenancies Act the landlord must keep the unit free of infestation, and that cost cannot be passed to a tenant — not through a lease clause, not through a rent increase, not out of the deposit, not by sending you the invoice. The narrow exception is an infestation caused by a tenant’s own negligence.
So for a renter the useful number is not the price of the treatment. It is the price of the treatment you were about to pay for by mistake.
What does treatment cost by pest?
| Pest | Typical cost | Visits usually needed |
|---|---|---|
| Mice or rats | $200–$500 | Inspection, exclusion, follow-up |
| Cockroaches | $200–$600 | 2–3, weeks apart |
| Bed bugs, chemical | $300–$900 | 2–3 across 4–6 weeks |
| Bed bugs, heat | $1,000–$3,000 | 1–2 |
| Ants | $150–$350 | 1–2 |
| Wasps or hornets nest | $150–$350 | Usually 1 |
| Standard general treatment | $200–$450 | Depends on pest |
Size of the property matters less than most people expect. What moves the price is the species, how established it is, and how many visits the programme includes.
Who pays for pest control in an Ontario rental?
The landlord, in almost every case, and the law is not ambiguous about it.
The Residential Tenancies Act requires a landlord to maintain the rental unit in a good state of repair and fit for habitation. An infestation of bed bugs, cockroaches or rodents is not a lifestyle disagreement — it is a maintenance failure, and remedying it is the landlord’s obligation and the landlord’s bill.
What follows from that is the part people get wrong. The cost cannot be moved onto the tenant by any of the usual routes: a clause in the lease saying pest control is the tenant’s responsibility, a rent increase tied to the treatment, a deduction from the last month’s rent deposit, or simply forwarding the exterminator’s invoice. A lease term that contradicts the Act does not become valid because both sides signed it.
The exception is real but narrow: where the infestation was caused by the tenant’s own negligence. Section 33 requires tenants to maintain ordinary cleanliness, and a unit that genuinely breaches that standard can shift some responsibility. “Ordinary cleanliness” is a low bar, though — it is not a tidiness test, and bringing bed bugs home from a hotel is not negligence.
What should a tenant actually do?
In this order, and the first step is the one that decides everything afterwards.
Why do bed bugs cost so much more?
Because the job is the entire unit, not the insect.
Bed bugs live in seams, frames, baseboards and behind outlet covers, and the eggs survive most treatments. That is why a chemical programme is two or three visits spaced weeks apart — the later visits exist to kill what hatched after the first. Skip one and the clock restarts.
Heat treatment raises the whole space to a lethal temperature in one or two sessions, which is faster and considerably more expensive, and requires specialised equipment and serious preparation.
Either way, preparation is most of the work and it falls on the occupant: laundering and bagging, emptying furniture, moving things away from walls. A treatment done on an unprepared unit is money spent on a result that will not hold — which is the real reason companies insist on it.
Anyone promising a single-visit permanent fix for bed bugs is overselling. In a multi-unit building, treating one apartment while the neighbours go untreated is close to pointless, which is another reason this is a landlord-level problem rather than a tenant-level one.

What to do next
If you rent: write to your landlord today, in writing, describing what you have found. That single dated message is worth more than anything else you do this week — and do not pay an exterminator before you have sent it.
If you own: get two quotes and compare what is in them rather than the headline. A $300 treatment with one visit and a $550 treatment with three are not the same purchase.

Frequently asked questions
A standard single treatment runs about $200 to $450. By pest: mice roughly $200 to $500, cockroaches $200 to $600, and bed bugs $300 to $900 for chemical treatment or $1,000 to $3,000 for heat. Wasps and ants sit at the lower end.
Because the job is the whole unit, not the insect. Treatment means preparation, multiple visits, and often heating the entire space to a lethal temperature with specialised equipment. Chemical programmes need two or three visits spaced weeks apart to catch newly hatched eggs, and a single skipped visit restarts the problem.
The landlord, in almost every case. Under the Residential Tenancies Act the landlord must keep the unit fit for habitation and free of infestation, and those costs cannot be passed to tenants through a lease clause, a rent increase, a deduction from the deposit or an invoice. The narrow exception is damage or infestation caused by a tenant’s own negligence.
Ordinary cleanliness under section 33, reporting the problem promptly and in writing, and cooperating with treatment — which usually means preparing the unit as instructed and allowing access. Refusing access or skipping preparation is where a tenant can end up carrying part of the cost.
Report it in writing and keep a copy, then contact municipal property standards, which enforces the local maintenance bylaw. A tenant can also apply to the Landlord and Tenant Board for an order requiring the work and, in some cases, an abatement of rent. Documentation from the first day is what makes either route work.
A cockroach or mouse programme usually shows results within days but needs follow-up visits over several weeks. Bed bugs typically need two to three treatments across four to six weeks for chemicals, or one to two sessions for heat. Anyone promising a single-visit permanent fix for bed bugs is overselling.
For wasps or a single rodent entry point, often yes. For anything that breeds indoors — cockroaches, bed bugs, fleas — almost never, because the first treatment does not kill eggs. Ask what the quote includes: a price with follow-up visits built in and a price without them are different products.

Treatment prices come from published 2026 pricing guides of Toronto, GTA and Ontario pest control companies, checked 17 September 2026 — published by firms that sell the work, so treat them as market pricing and get a written quote after an inspection. The landlord’s maintenance obligation and the tenant’s cleanliness obligation are set out in the Residential Tenancies Act, 2006; disputes are decided by the Landlord and Tenant Board, and municipal property standards bylaws provide a parallel enforcement route.
