Wasp Nest: What to Do, and Above All What Not to Do
The hardware-store aerosol solves one nest in three and makes the other two worse. Here is the right approach based on nest location and time of season.

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 Rivière-des-Prairies–Pointe-aux-Trembles dwelling declared clear too early is one that calls back three months later. For a fly & Mosquito Control 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.
Fly & Mosquito Control: what Rivière-des-Prairies–Pointe-aux-Trembles's building stock demands
The area's structuring constraint is the edge between built-up areas and nature parks, the source of autumn waves of deer mice seeking to overwinter indoors. 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. Large lots allow a complete perimeter barrier, giving prevention a far better return than in dense areas.
Our fly & Mosquito Control protocol, step by step
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 Rivière-des-Prairies–Pointe-aux-Trembles, we schedule those follow-ups against the species' reproductive cycle rather than on a fixed date.
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 fly & Mosquito Control treatment in Rivière-des-Prairies–Pointe-aux-Trembles, 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.
