The house mouse (Mus musculus) is considered one of the most troublesome and economically important rodents in the United States. House mice thrive under a variety of conditions. They are found in and around homes and farms as well as in open fields and agricultural lands. House mice consume and contaminate food meant for humans, livestock, or other animals. They cause damage to structures and property, and they transmit diseases such as salmonellosis and swine dysentery.
