About Deer Mouse
The deer mouse (Peromyscus maniculatus) is a native North American rodent measuring 12–22 cm, easily identified by its sharply bicolored fur: rich brown above, pure white below, including belly, feet, and underside of tail. It is the primary reservoir and transmission source of hantavirus pulmonary syndrome (HPS), a rare respiratory disease with a fatality rate of approximately 38%. Humans acquire HPS by inhaling dust contaminated with deer mouse urine, droppings, or saliva. The deer mouse inhabits rural and semi-rural areas, entering buildings in autumn for warmth. Cleaning any suspected deer mouse contamination requires special precautions — wetting with disinfectant before wiping — to prevent aerosol inhalation.
