Bed Bugs in Your Building? Treat It Once, Done Right.
Bed Bug Heat Treatment for Apartment Buildings in Montreal

When one unit has bed bugs, the building usually does too. That's why we treat the building.
It often starts with a single call from one tenant. You treat that apartment, and a few weeks later the neighbour calls, then the unit upstairs. Each time feels like a new problem, but it's the same one moving through the building.
Bed bugs don't stay in one unit. They travel through shared walls, outlets, pipes, and hallways. Treating only the unit that called leaves the rest of the building free to send them back.
EliteXterm treats Montreal buildings as a whole, with professional heat, a plan your tenants can follow, and one guarantee that covers the entire building.
Why landlords choose heat over sprays
Heat reaches where sprays can't. We raise each unit to a lethal temperature and hold it there. Heat gets into mattresses, couches, wall gaps, and furniture joints, and it kills eggs as well as adult bugs. Sprays only hit what they touch, which is why spray treatments usually need two or three visits.
Tenants keep their belongings. We treat mattresses, furniture, and clothing in place. Nobody has to throw out their bed. That means fewer complaints, fewer replacement claims, and tenants who actually cooperate.
No chemicals left behind. No residue in kitchens, bedrooms, or children's rooms. Tenants can return the same day.
No dogs. Our inspections are visual and done by trained technicians, unit by unit.
How a building treatment works
1. Free building inspection
We inspect every unit we can access and map where the activity is. You get a clear picture: which units are active, which ones are at risk, and which ones are clean.
2. We handle tenant notices and consent
Access is where most building treatments fall apart. Tenants are not home, do not understand what is happening, or refuse entry.
We prepare the tenant notices and consent forms for you, in French and English, written in plain language. Quebec requires at least 24 hours' notice before entering a unit, and our schedule builds that in. You hand the forms out, we collect them, and every tenant knows exactly what to expect.
3. Preparation guides for every tenant
Each tenant gets a simple preparation guide (French and English) so their unit is ready on treatment day.
4. Treatment, top floor down
We treat about 3 to 6 units per day, working from the top of the building down so bugs are not pushed into units we have already finished. Each unit takes about 6 to 8 hours. Tenants step out for the day and come back the same evening.
5. One guarantee for the whole building
When every unit in the agreement is treated, your building is covered by a 12-month written guarantee. If verified activity comes back in a treated unit, we return and treat it at no extra cost.
Simple, fair payment
- No deposit required.
- Pay unit by unit, on treatment day, once our equipment is running in that unit.
- You only pay for the units we actually treat that day.
Pricing depends on the number and size of units. After the free inspection, you get a written proposal with two options: the full building at a building rate, or a targeted treatment of the affected units and every unit around them. The building rate is almost always the better value, because it ends the problem instead of chasing it.
What happens if a tenant refuses access?
It happens, and it is the number one reason building treatments stall. Here is how we handle it:
- Our notices explain the treatment clearly in the tenant's language, which removes most of the fear.
- We can speak with the tenant directly, in French or English. Many refusals come from one worry: "Will you throw out my bed?" The answer is no.
- A unit without access is rescheduled once, at the same rate.
- If access is still refused, that unit is documented and excluded, so you have a clear record of what was offered and refused.
Your obligations as a Montreal landlord
Under the Civil Code of Québec, landlords must keep their units fit for habitation. When bed bugs spread through a building, tenants can file at the Tribunal administratif du logement (TAL) and ask for a rent reduction, damages, or an order to treat.
Acting early, treating the whole building, and keeping written records (inspection results, notices, treatment dates, and the guarantee) protects you. Every EliteXterm building treatment comes with that paperwork.
This is general information, not legal advice.
Old building? No problem.
Many Montreal buildings were built decades ago with older wiring. We check each unit's electrical setup before we start and spread our equipment across the right circuits, using the kitchen range outlet and separate wall circuits. We work with your building's existing circuits, and for faster schedules we bring our own generator power. No blown breakers, no surprises.
