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.

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 Le Sud-Ouest, 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 Le Sud-Ouest 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 Le Sud-Ouest's building stock demands
The area's structuring constraint is stone foundations and dirt cellars in older houses, where rodents dig burrows that cannot be sealed without structural work. 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. Griffintown’s constant construction regularly displaces rat populations toward Pointe-Saint-Charles residential streets.
Landlord or tenant in Le Sud-Ouest: who does what
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 Le Sud-Ouest 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.
