Besides brown
rat (Rattus norvegicus) and black rat (Rattus rattus),
house mouse is the next most significant mammal
pest of stored products (Drummond, 2001; Đukić
et al., 2005). It breeds fast and tends to overpopulate.
It produces up to four litters a year, each with 5-12 young.
It reaches sexual maturity at the age of two months
and actively breeds when 70-75 days old. In natural environments,
it normally lives 1-1.5 years (Ružić, 1983;
Đukić et al., 2005). It nests in places that are close to
food sources, among sacs, in various cracks and crevices
and in other hidden places.
