In Sweden the house mouse and field mouse are the most common. The body (including the tail) usually measures 8-9 cm. A whole with a diameter of 5 mm is enough for a mouse to get in. A mouse becomes mature after only 35 days. A female mouse gets 4-6 litters a year with up to 6 pups in each. Under good circumstances a new litter may be born each 50th day. A female is pregnant for 18-21 days and fertile for approximately one year. It is an omnivore but prefers fruits, seeds, flour and grain products. It often gets in to properties via panel and cracks. House mice stay inside houses all year round while field mice get in during autumn.
