House Mice in Vermont

House mice breed rapidly. A house mouse is mature within 35 days after birth and can have a first litter of up to eight pups at 60 days old. This contributes to the fact that house mice infestation are often large in size. 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. Mice can squeeze through a hole as small as 1/4 inch and can quickly climb straight up an eight-foot wall in less than half a minute. In one year, one mouse produces up to 18,000 droppings; it will deposit hundreds of micro-droplets of urine every day as it marks its trails.

House Mouse Habitat

When they get 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. Mice are active mostly at night, but they can be seen occasionally during daylight hours.

House Mouse Behaviors, Threats, or 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.
