House mouse (Mus musculus domesticus)
The house mouse has become closely associated with humans and now lives mainly in buildings. The animal prefers dry rooms, but can adapt well to a variety of conditions (e.g. in coolers). The body length is approx. 10 cm, with a tail of about the same length. This twilight animal has large eyes and ears. The coat is dark grey to blackish on the upper side and changes to a lighter grey on the underside. House mice liver in small family groups with one male and several females. One female bears 5 to 8 litters a year averaging 6 young each. The house mouse feeds on a mixed diet of vegetable and animal foodstuffs.
The house mouse causes damage when it feeds on foodstuffs and contaminates them with excrements. Gnawing damage to objects, paper, textiles, e.g. to obtain nest material, is also significant. Certain diseases can also be transmitted in faeces, urine or foodstuffs mice have fed on.back
