The house mouse is so named because of its preference for cozy indoor spaces that are protected from the elements and near a food source. Those that do settle in fields or grassy areas will seek shelter inside garages, attics, and basements as soon as temperatures begin to cool in the fall.
House mice are brown or gray with hairless ears and tails. They will seek out and contaminate a wide variety of foods, foraging constantly as they generally to not store what they find. These enterprising rodents can squeeze through cracks and openings no bigger than the width of a dime, so sealing gaps in windows and doors is crucial to controlling potential infestation.
Evidence of house mice in your home will usually be small rod-shaped droppings in the basement or attic. You may also find chewed boxes, cloth, insulation, and other materials being used for nesting.
