Habitat: When brown rats invade buildings, they usually remain in the basement or ground floor. The rats also live in fields, farms, woodpiles and buildings. Brown rat nests are usually lined with shredded paper or cloth.

Impact: Damage caused by brown rats includes chewing on materials, urinating on food and eating stored foods. They have also been known to chew on wires, which may pose fire risks. They also carry disease and ectoparasites. Rats will also attack both animals and humans.

Prevention:

1. Rats like to eat, so keep your homes clean and do not leave food out.
2. Make sure that your home and storage areas are clean and dry.
3. Make sure that you clean your sheds, crawlspaces, and garbage cans often.
4. Close up any small holes and cracks they can come in through.
