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 area's structuring constraint is renovation work, which dislodges colonies established inside walls and pushes them toward still-intact neighbouring units. 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. Renovated and original buildings sitting side by side on the same street create persistent infestation pockets despite individual treatments.
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 mouse & Rat Extermination treatment in Hochelaga-Maisonneuve, 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.
Costs, timelines, and guarantee in Hochelaga-Maisonneuve
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 That is exactly why we do not quote over the phone without seeing the site — a blind number always ends up being revised.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 Hochelaga-Maisonneuve 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 Hochelaga-Maisonneuve
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 Hochelaga-Maisonneuve, 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.
