House mice thrive under a variety of conditions: they are found in and around homes and commercial structures as well as in open fields and agricultural lands. House mice consume and contaminate food meant for humans, pets, livestock, or other animals. In addition, they often cause considerable damage to structures and property. They can transmit pathogens that cause diseases such as salmonellosis, a form of food poisoning.
The Field Mouse is a small rodent, found in long rolling plains or alternately old houses and any place in between. Low on the food chain, these beasts reproduce at an alarming rate. They aren't especially vicious and rely on their size, speed, and own ingenuity to survive.
