What an Exterminator Costs in Montreal: the 5 Factors That Set the Price
Nobody can quote a price over the phone without seeing the site. Here are the five variables that actually determine the bill, and the corresponding ranges.

On this type of property, the first clues rarely appear at eye level. Look at baseboards, behind built-in furniture, under sinks, at basement rim joists, and where pipes pass through. A night-time noise inside a partition, an unusual persistent odour, dark trails along a wall, or granular debris near a crack are reliable signals. In Laval, the aggravating factor remains the island’s encirclement by the Rivière des Prairies and Rivière des Mille Îles, whose banks feed constant seasonal pressure inland: what shows up in your home often originates next door, and an inspection limited to your unit alone will miss it. Reporting early cuts both the cost and the number of visits.
Preventing a return after treatment
Reinfestation is almost never a product failure: it is an entry point left open or an attraction source never removed. After a preventive Inspection treatment in Laval, we hand over a list of fixes ranked by priority and cost, separating what you can do yourself from what requires a trade. For rental buildings and businesses, we add a dated intervention log — a document regularly required during a municipal inspection or a tenant dispute. Property owners across Laval can also subscribe to a seasonal preventive program with scheduled visits.
Costs, timelines, and guarantee in Laval
The price of a preventive Inspection treatment depends on three variables: the area to cover, the number of units involved, and how much preparation is already done. That is exactly why we do not quote over the phone without seeing the site — a blind number always ends up being revised. The inspection is free and the resulting quote is firm. The usual lead time in Laval is 24 to 72 hours depending on the season, with priority given to emergencies and food businesses. All our treatments carry a results guarantee: if activity resumes within the covered period, we come back at no charge.
Follow-up: how we know it is settled
The closing criterion is never "the occupants no longer see anything." It is the absence of captures on monitoring traps across two consecutive readings. The distinction matters, because a residual population easily spends three weeks under the radar before becoming visible again — and a Laval dwelling declared clear too early is one that calls back three months later. For a preventive Inspection treatment we place monitoring devices at the travel points identified during the inspection, then return to read them on a schedule set in advance rather than at random. Follow-up is included in the initial quote: it is not an extra visit to be sold to you later, it is the second half of the job.
