How Much Does Pest Control Cost in Montreal? (2026 Pricing Guide)

One of the first questions people ask when they discover a pest problem is: "How much is this going to cost me?" It is a fair question — and one that deserves a straight answer. Pest control pricing in Montreal varies widely depending on the type of pest, the size of your property, the severity of the infestation, and the treatment method used. This guide breaks it all down so you know exactly what to expect before you pick up the phone.

Pest Control Pricing by Pest Type (Montreal, 2026)

Here is a realistic pricing range for the most common pest control services in Montreal. These figures reflect what licensed, reputable exterminators charge — not the rock-bottom prices you might see advertised online.

• Bed bug heat treatment (1-bedroom apartment): $450–$700
• Bed bug heat treatment (2–3 bedroom unit): $650–$950
• Bed bug chemical treatment (per visit, 2–3 visits required): $200–$400
• Cockroach extermination (apartment): $150–$350
• Cockroach extermination (commercial kitchen): $250–$600
• Mouse and rat extermination + exclusion: $300–$650
• Ant extermination (interior + exterior): $120–$280
• Wasp nest removal: $150–$350
• Spider treatment: $100–$250
• General pest inspection (free at Blackline): $0

Factors That Affect the Price

Property Size

Larger spaces require more product, more time, and more equipment. A studio apartment costs significantly less to treat than a 4-bedroom house. For heat treatment, larger spaces require more heating units and longer treatment times, which directly affects the price.

Infestation Severity

A minor infestation caught early is far cheaper to treat than a severe, long-established one. For cockroaches, a light infestation in a single kitchen might require one treatment; a severe infestation throughout a building requires multiple visits and a more intensive protocol. For bed bugs, a single infested bedroom is much less expensive to treat than a whole-home infestation that has spread to multiple rooms.

Treatment Method

Heat treatment for bed bugs costs more upfront than chemical treatment but typically requires only one visit. Chemical treatment is cheaper per visit but usually requires 2 to 3 visits spaced 2 weeks apart, which can make the total cost comparable or higher. For most pests, the most effective treatment method is also the most cost-effective in the long run.

Number of Visits Required

Some treatments are single-visit; others require follow-up visits to ensure complete elimination. Cockroach treatments typically require 2 to 3 visits. Rodent exclusion may require an initial treatment visit plus a follow-up to seal entry points and check traps. Always ask how many visits are included in the quoted price.

What Is Included in a Free Inspection?

A professional pest inspection should include a thorough examination of all areas where pests are likely to be present or enter. At Blackline Pest Control, our free inspections include:

• Visual inspection of all rooms, including bedrooms, kitchen, bathrooms, and basement
• Identification of the pest species and assessment of infestation severity
• Identification of entry points and conditions that are attracting or harbouring pests
• A written treatment recommendation with a clear, itemized quote
• Explanation of the treatment process, products used, and safety information
• No obligation to proceed — the inspection is genuinely free

Why Cheap Pest Control Services Cut Corners

You will occasionally see pest control services advertised at prices that seem too good to be true — $49 cockroach treatments, $99 bed bug inspections that somehow include treatment. Here is what those prices usually mean in practice:

• Unlicensed technicians who are not certified by the Quebec Ministry of Environment
• Diluted or substandard products that do not meet Health Canada registration requirements
• Incomplete treatments that address visible pests but not the source of the infestation
• No follow-up visits or guarantees — if the pests come back, you pay again
• Pressure tactics to upsell unnecessary services once they are in your home

Blackline's Pricing Philosophy

At Blackline Pest Control, we charge fair prices for complete, guaranteed work. Our quotes are transparent — no hidden fees, no surprise add-ons. Every treatment comes with a guarantee period: if pests return within the guarantee window, we return at no charge. We would rather charge a fair price once and solve the problem completely than offer a low price that requires multiple return visits.

We serve Montreal, Laval, the South Shore, and the Vaudreuil region. Call us at 514-809-1999 for a free inspection and written quote.
