Although not native to North America, the house mouse was introduced accidentally to seaport towns.
It is now widespread throughout the United States.
It occurs either as a commensal or feral animal in practically all parts of the U.S. 
As commensal animals, house mice live in close association with man – in houses, outbuildings, stores, and other structures.
Where conditions permit, feral mice may be found in fields, along watercourses, and in other places where vegetation is dense enough to hide them.
