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 Côte-des-Neiges–Notre-Dame-de-Grâce dwelling declared clear too early is one that calls back three months later. For a commercial Pest 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.
Commercial Pest Control: what Côte-des-Neiges–Notre-Dame-de-Grâce's building stock demands
The area's structuring constraint is garbage chutes and refuse rooms, which act as a vertical highway for rodents and cockroaches between floors. 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. The large student population tied to Université de Montréal drives late-August moves that coincide with the annual peak in bed bug reports.
Our commercial Pest 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 Côte-des-Neiges–Notre-Dame-de-Grâce, we schedule those follow-ups against the species' reproductive cycle rather than on a fixed date.
Landlord or tenant in Côte-des-Neiges–Notre-Dame-de-Grâce: 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 Côte-des-Neiges–Notre-Dame-de-Grâce 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.
