Rat types found in Canada include two species that cause the vast majority of home and business infestations — the brown rat and the black rat — plus the less common pack rat in some regions. Knowing which rat types found in Canada you’re dealing with helps determine where they nest, what they eat, and how quickly a small problem can turn into a full infestation. This guide covers each species in detail, plus where rats hide during the day and what to do if you spot one on your property.

Where Do Rats Go During the Day?
During the day, rats hide in dark, quiet, rarely-disturbed spots to stay safe from predators and people. Common daytime hiding places include wall voids, attics, crawl spaces, basements, woodpiles, dense shrubs, sewers, and cluttered storage areas. Because rats are nocturnal, they rest in these hidden nests and burrows once the sun rises, only coming out after dark to search for food and water.
Where rats hide inside your home
- Attics and roof spaces: warm, quiet and full of insulation for nesting. Roof rats (black rats) especially prefer high places.
- Wall voids and ceiling spaces: rats travel and nest between studs and joists, which is why you hear scratching at night.
- Crawl spaces and basements: dark, damp areas with easy access to plumbing and the outdoors.
- Behind and under appliances: stoves, fridges, dishwashers and water heaters offer warmth and hidden gaps.
- Garages and storage rooms: clutter, cardboard boxes and stored pet food or birdseed.
Where rats hide outside
- Burrows: Norway rats (brown rats) dig burrows along foundations, under decks, sheds, concrete slabs and garden beds.
- Woodpiles, compost and garbage areas: shelter right next to a food source.
- Dense shrubs, ivy and hedges: common daytime cover for roof rats in the Lower Mainland.
- Trees and fences: roof rats climb and travel along branches, fences and power lines.
- Sewers and storm drains: a major home for brown rats in towns and cities.
Brown rats vs. roof rats: where each one hides
In BC, the two main pest rats behave differently. Norway (brown) rats stay low: burrows, basements, crawl spaces and sewers. Roof (black) rats live high: attics, ceilings, trees and thick vegetation. Knowing which one you have tells you where to look and where to treat.
Is It Bad to See a Rat During the Day?
Usually, yes. Rats are nocturnal, so a rat out in daylight often means:
- The population is large and weaker rats are pushed out to feed in daytime.
- Their nest has been disturbed by construction, renovation or flooding.
- Food is scarce at night, or an easy daytime food source is available, such as bird feeders, pet food or fallen fruit.
A rat seen in daylight is a strong sign there are many more hidden nearby. It is best to act quickly.
How to Tell Where Rats Are Hiding
- Droppings: dark, capsule-shaped droppings about 1–2 cm long cluster near nests and feeding areas.
- Rub marks: greasy dark smudges along walls, beams and entry holes.
- Gnaw marks: chewed wood, plastic, wiring and food packaging.
- Noises at night: scratching, scurrying or squeaking in walls and ceilings.
- Burrows and runways: holes about 5–8 cm wide along foundations, with packed-down paths through grass.
- Nesting material: shredded insulation, paper and fabric in hidden corners.
How to Get Rid of Rats Hiding in Your Home
Seal entry points (rats can squeeze through gaps about the size of a quarter), remove food and clutter, trim vegetation away from the house, and keep garbage and compost sealed. Because rats hide in walls and roof spaces, a professional inspection is the fastest way to find every nest and entry point. Our rat control service combines inspection, tamper-resistant baiting and trapping, exclusion work and follow-up visits.
