House mouse

Mus musculus

Dark to black on the upper side, gray on the underside. Body and tail each 9 cm long. High reproductive capacity. 4-8 young per litter, 4-6 litters per year. Prefers to live in dry rooms, can adapt well to different conditions, e.g. cold (occurs in cold stores). Food and animal feed, but also textiles, paper, leather, etc. are eaten and contaminated by excrement. The presence of mice on cereals differs from rat infestation in the presence of small, approx. 1-2 mm large gnawing shavings (husks, pieces of grain). Also transmits diseases, e.g. paratyphoid, trichinosis, etc.
