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.

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 That is exactly why we do not quote over the phone without seeing the site — a blind number always ends up being revised.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 Lachine 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 Lachine 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.
Preventive Inspection: what Lachine's building stock demands
The area's structuring constraint is the open volumes and high ceilings of converted lofts, which call for treatment methods different from a partitioned dwelling. In practice, that means a treatment limited to the room where the problem was noticed leaves the source untouched. Our technicians therefore map the building before applying anything: a survey of unit separations, plumbing and electrical penetrations, floor voids, and attics. That map determines the treatment's extent — sometimes a single unit, often an entire vertical stack. The Lachine Canal corridor, with its bike paths and landscaping, sustains continuous rodent pressure on adjacent homes.
Our preventive Inspection protocol, step by step
The free inspection identifies the species, the extent, and the entry points, and leads to a written quote detailing products, method, schedule, and guarantee. Treatment follows, applied with Health Canada-approved products and a preparation whose instructions are given to you in advance — the part clients most underestimate, and the one that separates a successful treatment from one that must be redone. One or two follow-up visits then verify the outcome in the following weeks, with free touch-ups if activity persists. In Lachine, we schedule those follow-ups against the species' reproductive cycle rather than on a fixed date.
