House Mice in El Paso TX and Anthony NM

House mice prefer to move along baseboards and counter-tops, marking their territory with urine and feces, and typically build their nests close to a food source, which could be in your home. Their droppings are small and brown, about the size of a sesame seed. Because they breed quickly, it’s possible for your home to be completely infested before you even notice their presence. Mice are acrobatic and can jump about a foot straight up from a standing position and can jump down more than six feet without getting hurt.

House Mouse Environment

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.

House Mouse Habits and Dangers

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 inside walls can spark, causing interior walls to catch fire. Because they breed at such a rapid rate, a small house mouse problem can quickly become very dangerous!
