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 the river’s spring flooding, which saturates soils and pushes ants, sowbugs, and rodents into basements within days. 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. We recommend a systematic post-flood inspection in this sector — the period when infestations establish fastest.
Warning signs to watch for in Vieux-Châteauguay and Nortel
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 Châteauguay, the aggravating factor remains the river’s spring flooding, which saturates soils and pushes ants, sowbugs, and rodents into basements within days: 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.
Costs, timelines, and guarantee in Châteauguay
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 That is exactly why we do not quote over the phone without seeing the site — a blind number always ends up being revised.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 Châteauguay 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.
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 Châteauguay 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.
