House Mouse 

Deer Mouse

Other Names: Common House Mouse, Domestic House Mouse

Excellent hearing, vision, smell and touch have enabled the mouse to be highly adaptable to homes and indoor buildings. All they need is a 1/4" opening to be able to enter a building, so they often have access to many places along the building's perimeter.
