House Mice and Deer Mice are the most common mice found in Western Washington.
House Mice tend to be more commonly found in urban and suburban developed areas. They are identified by their small size, pointed nose, black protruding eyes, large ears, and hairless tail.
Deer Mice are more common in rural areas. They look similar to House Mice, but have white feet, a white underside, and a long slightly furry tail with a whiteish underside. Deer Mice are also the species most frequently associated with Hantavirus.
