Mouse or rat? How to tell the difference
The house mouse measures 6-10 cm (without the tail), leaves rice-grain droppings and slips through a 6 mm hole. The Norway rat is much larger, its droppings are 1-2 cm, it burrows and runs along foundations. Treatment differs by species.
The 5 signs of an infestation
- Droppings along walls, under the sink, in drawers.
- Running or scratching noises in walls and ceilings at night.
- Chewed food packaging, wires or insulation.
- Grease marks and runways along baseboards.
- Persistent ammonia-like urine smell.
Why traps alone are never enough
Store traps and poisons kill a few rodents but don't close the access points: the colony rebuilds through the same holes. Worse, a poisoned rat dying inside a wall creates odours and flies for weeks. The key is sealing the entry points, which DIY solutions ignore.
What a professional protocol does
Full inspection, locked bait stations (child/pet-safe), targeted traps, then systematic sealing of conduits, cracks and door gaps, plus a follow-up visit. It's the elimination + exclusion combo that solves it for good, with a written guarantee.

Frequently asked questions
Are rodents dangerous to health?
Yes: they contaminate food and surfaces (salmonella, hantavirus), and their droppings are allergens. Chewed wires are also a real fire hazard.
How long to eliminate an infestation?
Usually 2 to 4 weeks depending on extent: active elimination then sealing and a follow-up visit to confirm no return.
How much is rodent control?
From about $99 depending on the species, area and number of access points to seal. Detailed quote after inspection, no commitment.
Are baits safe with kids or a dog?
Yes: we use locked stations and Health Canada-approved products placed out of reach. Household safety is part of the protocol.
