The house mouse is the most common rodent pest in most parts of the world. It can breed rapidly and adapt quickly to changing conditions. House mice have an adult body length (nose to base of tail) of 7.5–10 cm (3.0–3.9 in) and a tail length of 5–10 cm (2.0–3.9 in). The weight is typically 10–25 g (0.4–0.9 oz). Mice make their nest from soft material like paper, insulation or furniture stuffing. These nests can be found in walls, ceiling voids, storage boxes, drawers, under appliances or within upholstery. Outside nests are found in debris or in ground burrows.
House mice contribute to the spread of several human and animal diseases, including bubonic plague. They also carry a virus that may contribute to cancer in humans. Where abundant, house mice consume large quantities of crops and contaminate foods with their droppings. They can destroy woodwork, furniture, upholstery, and clothing.
