House Mice in Albuquerque NM

Some people keep mice as pets, but wild house mice can become a major issue for homeowners. Mice are nocturnal, preferring to do their damage at night. Also, they are omnivorous, meaning they’ll eat pretty much anything they can get their hands on, including their own droppings. House mice thrive throughout the year and can be found in homes, commercial buildings, open fields, and agricultural lands. They contaminate food meant for humans and pets as they forage, dropping feces and urine along the way. House mice cause considerable damage to structures by chewing through walls and transmit pathogens that cause diseases like salmonella, a form of food poisoning. House mice breed at a very rapid rate, which is why their infestations can be so dangerous.

House Mouse Habitat

Outdoors, house mice construct nests in fields and beneath trees and shrubs. Indoors, mice will build nests in quiet undisturbed places like wall voids, kitchen cabinets, attics, and garages. Droppings, fresh gnaw marks, and tracks or rub marks indicate areas where mice are active. Nests are made from finely shredded paper or other fibrous material, usually in sheltered locations. House mice have a characteristic musky odor that reveals their presence. Mice are active mostly at night, but they can be seen occasionally during daylight hours.
