A mouse is a small rodent with a pointed nose, furry round body, large ears and a long, often hairless, tail. There are hundreds of types of mice, divided into subfamilies of either Old World or New World species. Common varieties include deer mouse, house mouse, field mouse, wood mouse, dormouse, spiny mouse and zebra mouse.
Small and slender, 3 to 4 inches long, with large ears, small eyes and pointed nose. Light brown or light gray. Droppings are rod-shaped.
Mice live everywhere outside, and are found more often indoors than rats because they are smaller and more able to fit through small openings. Mice can fit through a crack or hole 1/4 of an inch or larger—about the width of a pencil. Their territory generally ranges 10 to 30 feet from their nest. They are curious but wary. They are also excellent climbers, making rodent control difficult. They can enter your home through holes in soffit vents, around cables entering the building, and through turbines and box vents on the roof.
