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.

In Quebec, the landlord must keep the dwelling habitable, which includes the absence of vermin: extermination is at their expense when the infestation is not caused by the tenant. The tenant must give prompt notice and provide access. In practice, nearly every dispute brought before the Tribunal administratif du logement turns on those two obligations, not on the principle. That is why we systematically recommend a dated written notice — email or letter — describing what was observed, where, and since when. On our side, for every building in Saint-Laurent we supply a dated intervention log: visit dates, products used, units treated, follow-ups scheduled. It is the document a municipal inspection asks for, and the one that protects the owner in a dispute.
Access, scheduling, and being on site in Saint-Laurent
A failed preventive Inspection treatment is often a treatment cut short. The dwelling must be empty of occupants and pets during application and for the indicated drying time — generally four to six hours for a chemical treatment. Aquariums must be covered and their pumps switched off. We ask for clear access to every room, including closets and the basement. In Saint-Laurent, a significant share of missed appointments comes down to a key that could not be found or an occupant who had to come back: those visits are billed anyway, so they are worth avoiding. For wasp nests and commercial work we operate in the evening or before opening — the only window when the whole colony is present, or when food preparation areas are clear.
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 Saint-Laurent 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.
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 Saint-Laurent, 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 Island of Montreal can also subscribe to a seasonal preventive program with scheduled visits.
