7 Bed Bug Signs Most People Miss
Bites are the best-known sign — and the least reliable. Here are the seven clues a technician looks for first, and why the order matters.

Warning signs to watch for in Boulevard Pie-IX and Nord-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 Montréal-Nord, the aggravating factor remains shared plumbing stacks and dropped ceilings in these blocks, which connect every unit in a stairwell and make unit-by-unit treatment ineffective: 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.
Landlord or tenant in Montréal-Nord: 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 Montréal-Nord 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.
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 Montréal-Nord 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 Montréal-Nord's building stock demands
The area's structuring constraint is shared plumbing stacks and dropped ceilings in these blocks, which connect every unit in a stairwell and make unit-by-unit treatment ineffective. 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 favour agreements with building owners to treat the entire stairwell here — the only approach that yields lasting results in this building type.
