House Mice in Virginia

The house mouse is found across the nation and is typically the most common household rodent problem. This is because house mice are dependent on human activity for survival! They depend on human habitats for shelter and food, which is why they commonly infest homes here in Virginia. House mice are known to contaminate food meant for humans and pets as they forage, dropping feces and urine along the way. The biggest concern is that house mice cause considerable damage to structures by chewing through walls and transmit pathogens that cause diseases like salmonella and more.

House Mouse Environment

Despite their name, house mice can live both indoors and outdoors. When they are outside, they construct nests in fields and beneath trees and shrubs. Inside, 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. The house mouse is active primarily at night. However, they can be seen during day when there is a bad infestation or when they are hunting for food.
