Rats are some of the most troublesome and damaging rodents in the World. They eat and contaminate food, damage structures, and property, and transmit parasites and diseases to other animals and humans. Rats live and thrive in a wide variety of climates and conditions and are often found in and around homes and other buildings, on farms, and in gardens and open fields.
