Deer mice prefer rural, outdoor areas. They are rarely a problem in urban or residential areas, but can be a common pest in farming areas, summer/vacation homes, outbuildings, sheds, and suburban homes near wooded areas.
Deer mice often nest in old fence posts, tree hollows, log piles, abandoned bird nests and beneath decks. During winter months, they may invade homes, garages, sheds, or rarely used vehicles to seek shelter. Inside, they can make their nest in storage boxes, stuffed furniture, drawers, wall voids, and right areas in basements or attics. Deer mice feed at dusk and dawn, preferring insects, seeds, nuts, berries, and small fruits.
Deer mice are a medical concern because they are the common carrier of the Hantavirus. This virus is transmitted primarily by the inhalation of dust particles contaminated with the urine, feces, or saliva of infected deer mice.
