Rodent and mice. Most kinds live in woods and fields, but three kinds live with people: the house mouse, Norway rat and roof rat.
Rats and mice spoil your food, carry diseases, and they’re dirty. They soil your house with their droppings. They like open garbage cans, dumpsters, sewers and rubbish heaps. If you see a rat or mouse, you can be sure there are many more. They usually hide by day and come out at night. Mice are about 3 inches long, not counting the tail. Rats are much larger — up to a foot long, not counting the tail.
Rats and mice are curious. They eat a variety of foods, including grain and seed, nuts, meat, candy and processed cereal. They have poor eyesight but excellent senses of smell, taste and touch. They are mainly active at night.
House mice have a naked tail; native mice have a slightly furred tail. Roof rats are sleek and graceful; their ears extend past their eyes. Norway rats are large and heavy bodied; their ears do not reach past their eyes and they can weigh more than a pound.
