In Canada, there are different species of rodents. Knowing how to tell them apart is important since they don’t all have the same habits. Rodents carry viruses and are often a danger to humans.

Discover the different species that you may be likely to encounter in your home.

The different rat species

Rats, which are larger than mice, habitually colonize attics, lodge under concrete and porches and in a building’s walls. They pose a significant risk to your health since they can transmit many serious diseases and introduce virus-carrying parasites into your home, such as fleas, ticks and lice.

Roof rats

Roof rats are characteristically dark brown and small in size with ears at the back of their head. They can instinctively detect the traps we set for them. They can also measure between 13 and 18 inches long.

Norway rats

Norway rats are very similar to roof rats but differ in their habits. Essentially, the Norway rat prefers damp places like toilets and likes to build tunnels and burrows at ground level.

The various mouse species in the province

Mice are known to invade your home in search of food, heat and water. They typically reproduce extremely fast, since they can produce 200 descendants in only 4 months time.

Mice also represent a danger to humans since they can contaminate food and transmit diseases through their excrement and saliva, including hantavirus.

House mice

House mice, also called domestic mice, do not hibernate and are active all year round. They can be identified by their pointed snout, their big hairy ears and their greyish hairs. They also have scales on their tail.

Field mice

It is very rare to find field mice in our home. Indeed, this species prefers sheds and backyards where fruits and vegetables are stored. They like to eat tree seeds, insects and legumes. It is therefore more of a threat to farmers than to a home’s inhabitants. They can be identified by their yellowish belly hairs and the brown fur on their backs.

Deer mice

This mouse species, brown on top and white on the legs and belly, equipped with a hairy tail, is well known by the health authorities. Indeed, the deer mouse is the most common carrier of the deadly hantavirus. It has a habit of building nests in trees and under logs, and enters homes in winter to find shelter, usually in attics.
