Habits

The deer mouse feeds at dusk and dawn, preferring insects, seeds, nuts, berries and small fruits.

Habitat

Deer mice often nest in sheltered outdoor areas such as old fence posts, hollow tree logs or piles of debris. During the winter months, deer mice may invade homes, garages, sheds or rarely used vehicles to seek shelter. Inside, attics and basements make the ideal deer mouse habitat. The deer mouse also builds its nest in storage boxes, stuffed furniture, drawers and wall voids.

Threats

The deer mouse transmits the potentially fatal Hantavirus Pulmonary Syndrome. The disease can be transmitted through contact with mouse carcasses, or by breathing in aerosolized urine droplets of infected deer mice.
