Why do house mice move from fields into houses after crops are harvested?

House mice (Mus musculus) are highly adaptive rodents that exhibit a behavioral tendency to move when their habitat changes. At temperate latitudes, these mice often inhabit outdoor environments such as croplands and fallow fields. When crops are harvested or fields are plowed, the mice lose their established cover and food sources, prompting them to relocate to other fields or into human buildings to survive.1
