Mice
The house mouse has large ears and is light brown to dark grey, with a lighter colour on its belly. It is often found in urban areas. The deer mouse is brown or grey with a white belly and feet. The white colour on the underside of its tail is an easy way to spot a deer mouse. It may invade buildings near fields and woodlands in the fall.
Knowing the type of pest you have can help you figure out the best approach to controlling them. (For example, a rat trap is too large to capture a mouse.)
Should I be concerned?
Mice and rats are carriers of disease, and can damage property. The deer mouse is the most common carrier of the deadly hantavirus.
