Noises in the Walls at Night: Mouse, Rat, Squirrel, or Something Else?
The time of the noise, its height in the wall, and its rhythm are almost always enough to identify the animal. Here is how to read those three clues.

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 Ville-Marie (Centre-Ville) dwelling declared clear too early is one that calls back three months later. For a mouse & Rat Extermination 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.
Mouse & Rat Extermination: what Ville-Marie (Centre-Ville)'s building stock demands
The area's structuring constraint is the concentration of hotels, restaurants, and short-term rentals, which multiplies bed bug introductions via luggage. 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. High-rises require access planning with building management and treatment by vertical stack rather than by isolated unit.
Costs, timelines, and guarantee in Ville-Marie (Centre-Ville)
The price of a mouse & Rat Extermination 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 That is exactly why we do not quote over the phone without seeing the site — a blind number always ends up being revised.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 Ville-Marie (Centre-Ville) 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.
Access, scheduling, and being on site in Ville-Marie (Centre-Ville)
A failed mouse & Rat Extermination 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 Ville-Marie (Centre-Ville), 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.
