Rat extermination — urgent response
The Norway rat (brown rat) is gaining ground in Montreal and the South Shore. Fast intervention, entry-point diagnosis, monthly program available for businesses (separate fee).
The Norway rat (brown rat or sewer rat) has become a growing problem in Greater Montreal since 2020. Bigger, smarter and more dangerous than the mouse, it digs tunnels under foundations, contaminates food storage areas, and transmits leptospirosis, salmonella and rarely hantavirus. A rat infestation is an emergency — their reproduction and trap-shyness make this a pest only a professional protocol can eliminate.

Signs of infestation
How to tell if you have them
These indicators appear first. Visible presence during the day almost always signals an established infestation.
- Capsule-shaped droppings up to 2 cm long
- Burrows near foundation, compost or shed
- Loud scratching sounds in walls or under floor
- Greasy trails along interior or exterior walls
- Deep gnawing on wood, PVC, soft metal
Why act
Risks and consequences

- 4Major contamination of commercial storage areas
- 5Population that can double every 2 months without intervention
Our treatment
Professional method, structured protocol
Rat intervention requires a reinforced protocol. Phase 1: inspection of exterior burrows and activity points, deployment of maximum-security tamper-proof bait stations and industrial mechanical traps. Phase 2: adjustment visits at 7 and 14 days (included in the rat protocol). Phase 3: exclusion diagnosis — locating and marking burrows, openings > 1.5 cm and weak points, with a materials recommendation report (galvanized metal mesh, mortar) that you or your contractor can seal. A monthly maintenance program with reports is available for businesses at a separate fee.
Prevention
Prevent their return
- Eliminate exterior water sources (containers, blocked gutters)
- Keep compost in sealed, off-ground bins
