Mice are a common rodent throughout Wisconsin. They are a serious issue for homeowners and business owners if they can gain access. Mice only need a ¼-in of space to gain access to a building. Once inside, a mouse can wreak havoc with their gnawing, nesting, mating, and droppings. The most common mouse here in Wisconsin is the house mouse.
The house mouse is usually grey to light brown in color and about 3-4 inches in length. A mouse has a stereotypical appearance with a long pointed snout, a long skinny tail, and large rounded ears. Mice have poor eyesight. Therefore, they rely on their long whiskers to sense their surroundings. They are quick little rodents that will dart away if they sense danger. Mice primarily feed on grains and other plant matters.
