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 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 Saint-Léonard, we schedule those follow-ups against the species' reproductive cycle rather than on a fixed date.
Warning signs to watch for in Boulevard Lacordaire and Rue Jean-Talon Est
On this type of property, the first clues rarely appear at eye level. Look at baseboards, behind built-in furniture, under sinks, at basement rim joists, and where pipes pass through. A night-time noise inside a partition, an unusual persistent odour, dark trails along a wall, or granular debris near a crack are reliable signals. In Saint-Léonard, the aggravating factor remains basement units, whose ground-level windows and separate entrances multiply the access points to secure: what shows up in your home often originates next door, and an inspection limited to your unit alone will miss it. Reporting early cuts both the cost and the number of visits.
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 Saint-Léonard, 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 Saint-Léonard
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 That is exactly why we do not quote over the phone without seeing the site — a blind number always ends up being revised.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 Saint-Léonard 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.
