Common Arizona House Mice
The house mouse is the domestic rodent most frequently found in and around homes, businesses, and outdoor sheds. These creatures are well adapted to survival indoors. Generally, they cause only minor damage when nesting and active outdoors, but are capable of getting inside structures in order to get food and protective habitats.
They only need a crack of about one-fourth of an inch or a hole about the size of a dime to get inside. Once indoors, away from the elements and predators, their populations can multiply very quickly. In favorable interior environments, one house mouse female might produce from 30 to 50 or more mice in her lifetime. Fecal droppings, shreds of paper and packaging, and dark-colored rub marks on walls are telltale signs of their presence indoors.
