House Mice in Central and Eastern Virginia

The house mouse is one of the most common pest problems for homeowners. House mice are commensal, meaning they are generally found living in close association with humans and dependent upon the human habitat for shelter and food. 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 in humans. This, paired with the fact that they breed rapidly, can lead to dangerous house mice infestations.

House Mouse Habitat

As mentioned before, house mice are named as such because they commonly infest homes. House 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 when there is a serious infestation.

House Mouse Habits & Dangers

House mice will feed on a number of things, but they prefer cereal and grains. House mice contaminate food and are implicated in the transmission of diseases such as salmonella and bubonic plague. The house mouse can cause significant damage to structures by gnawing and tunneling through walls. Mice have also been implicated in the generation of fires and explosions in homes and buildings. Chewed, exposed wires can be a major fire hazard if they begin to spark.
