If there are good living conditions, (food, water and shelter), Mice can multiply rapidly. They can produce about 8 litters in a lifetime; each litter can have 4-7 pups. A house Mouse in a city environment may spend its entire life in buildings. In rural and suburban settings, it may not only live inside but be found outside near foundations, in the shrubbery, weeds, crawl spaces, basements, or in garages. They survive well on weeds, seeds, or insects, but when their food supply is shortened by the colder months they move inside nesting closer to a food supply. They make their nest from soft material like paper, insulation, or furniture stuffing. These nests are found in many places including wall voids, ceiling voids, storage boxes, drawers, under major appliances or within the upholstery of furniture. Outside, the nests are found in debris or in ground burrows. Mice can eat about 10 to 15% of their body weight every day.
