How much does an exterminator cost in Montreal in 2026?

In Montreal, the exterminator cost generally falls between $250 and $1,500, depending on the pest, the severity of the infestation and the area to be treated. Most standard residential jobs land in the $250 to $700 range per treatment.

Here are the average prices seen in Montreal in 2026, as a guideline:

Mice and rats: $250 to $900 (traps, bait stations and sealing of entry points)
Bed bugs: $250 to $1,500 (multi-visit protocol)
Carpenter ants: $300 to $1,250 (colony treatment)
Wasps and hornets: $150 to $650 (nest removal)
Cockroaches: $250 to $600 (2 to 3 treatments)
Spiders: $250 to $550 (residual pesticide)

These amounts are estimates, since every situation is unique. For a fixed price tailored to your specific case, our online calculator generates one in about a minute, with no inspection to wait for and no sign-up.

Exterminator cost in Montreal by pest

The cost of extermination varies a lot from one pest to another, because the protocol, the number of visits and the approved products all differ. Here is what each intervention covers in Montreal, and why prices swing so much from one case to the next.

Price for mouse and rat extermination

For rodents, expect $250 to $900. The price depends mainly on the number of entry points to seal and the scale of the infestation. A typical intervention combines mechanical traps, secured bait stations and sealing work to prevent re-infestation.

Our mouse extermination service includes follow-up until the problem is completely gone. For heavier cases, rat extermination calls for expert handling of rodenticides. In Montreal, the age of the housing stock multiplies the ways in (foundation cracks, worn joints), which explains how much sealing weighs on the final bill.

Price for bed bug extermination (2-treatment protocol, 21 days apart)

Bed bug extermination in Montreal generally costs $250 to $1,500. The gap comes down to the method chosen (chemical or heat treatment) and the number of rooms affected.

The standard protocol relies on two treatments 21 days apart with Temprid SC from Bayer Canada: the first visit eliminates the adults, the second neutralizes the nymphs hatched from eggs in the meantime. Bed bugs are not a matter of hygiene, but they move quickly through an apartment building, which can force neighbouring units to be treated as well and drive the cost up.

Price for carpenter ants, wasps and cockroaches

Carpenter ants ($300 to $1,250) tunnel through wood and can cause structural damage. The treatment aims to locate and then wipe out the main colony: once the queen is neutralized, the colony collapses. Our carpenter ant extermination combines targeted baits with an exterior perimeter treatment.

For wasps ($150 to $650), the price depends mostly on how accessible the nest is. Cockroaches ($250 to $600) require 2 to 3 gel bait treatments; our cockroach exterminator also treats the hidden areas behind appliances. Spiders, for their part, are handled with a residual pesticide applied both indoors and outdoors.

What factors make extermination prices vary?

Two infestations that look alike can produce very different bills. Understanding what influences the price of an extermination saves you from unpleasant surprises and helps you compare quotes on the right basis.

Infestation, square footage, number of treatments and written guarantee

Here are the main factors that move the price of an exterminator in Montreal:

Type of pest: some are settled in a single visit, others require several treatments spaced out over time.
Severity of the infestation: the more established the colony, the longer and costlier the intervention.
Square footage and building type: a two-bedroom apartment is not treated like a multi-storey house or a commercial space.
Method and products: a heat treatment costs more than a targeted chemical treatment.
Guarantee and follow-up: a written guarantee that comes with follow-up visits can change the final amount.

Building type carries a lot of weight: residential extermination in a condo is not billed like a commercial job subject to MAPAQ standards. Many exterminators also charge inspection fees of $50 to $125, usually deductible from the final invoice if you hire them.

How to pay a fair price for a certified exterminator

The lowest price is not always the best deal: a sloppy treatment costs more to redo than a job done right the first time. Here is how to make sure you are paying for a real result, not for a promise.

Insist on a free quote and a written guarantee on the invoice

Before any work starts, ask for a free, detailed quote. A real guarantee is never a verbal promise: it is a written commitment, printed directly on your invoice. It must spell out four things:

the exact length of the coverage,
the pests covered by the treatment,
the conditions for a return visit,
the commitment to come back at no charge if the problem returns.

If an exterminator refuses to put these items in writing, look elsewhere. That is exactly what separates a reliable, guaranteed service from an inflated invoice with no recourse.

Check the certifications: Health Canada, MAPAQ and approved products

A certified exterminator only applies products approved by Health Canada, and strictly respects the prescribed doses. For businesses and food establishments, compliance with MAPAQ standards is not optional.

These certifications are not an administrative detail: they guarantee a treatment that is both effective and safe for your family and your pets. Reputation matters just as much. SOS Extermination is regularly called on as an expert by major Quebec media outlets, as our press coverage shows.

How much does a bed bug exterminator cost in Montreal?

The average cost of bed bug extermination in Montreal sits around $250 to $700 per standard treatment, and climbs if the infestation is widespread or if you choose a heat treatment. Since the protocol often calls for two visits 21 days apart, always ask whether the quoted price covers all the treatments.

Is the inspection or the quote free?

At SOS Extermination, the quote is free and comes with no obligation. Some exterminators charge inspection fees of $50 to $125, but that amount is usually deductible from the invoice if you hire them. Be wary of a price given over the phone without anyone seeing the premises: every infestation is different.

Does the price include travel and follow-up visits?

In most cases, yes: travel within Greater Montreal is included, except for the most remote areas. Above all, check that follow-up visits and the written guarantee are part of the quoted price, because that is what ensures complete eradication rather than a one-off visit with no follow-through.

Paying for a guaranteed result, not just a treatment

The real cost of an extermination is not the amount written on the invoice: it is the risk of paying twice for a job done badly. A certified exterminator, a written guarantee and transparent follow-up are worth every dollar invested.

Next steps to deal with your infestation in Montreal

You now have a clear idea of the price of an exterminator in Montreal and the factors that make it vary. The logical next step is simple: get an exact figure for your situation, then schedule the intervention. Whether it is mice, bed bugs or carpenter ants, a transparent price and a written guarantee should always come with the service.

A problem solved on the first try always costs less than a problem that keeps coming back.
