The Norway rat – also known as the brown rat is larger and more aggressive than the Roof Rat. It is dull brown in color and measures between 12 1/2″ to 17″ from nose to tail. The nose is blunt with small ears and small eyes. The tail is shorter than the head and body combined.
The young rats reach sexual maturity in 2-3 months. The female averages 7 litters per year with 8-12 pups per litter. Adults live about one year. They live in colonies. The Norway rat generally prefers to live in underground tunnels. Their nesting burrows on the outside are often along the foundations of walls. As the rat family grows, more burrows are built resulting in lots of underground tunnels. Inside buildings, Norway rats commonly nest on the lower levels but while the population grows, they may go in attics and ceiling areas.
Rats are nocturnal with their peak activity taking place at dusk or before dawn. When the population is large or the colony is hungry and disturbed, activity can take place during the day too.
The roof rat is also called the black rat. It is slimmer than the Norway rat and has larger ears. The tail is longer than the combined length of the body and head. Roof rats’ nests are usually in the ceilings and attics. Both roof rats and Norway rats are good climbers and can climb up the inside and outside of pipes. Roof rats can climb even wires. Female rats have up to 7 litters per year of 8-12 pups per litter.
Rats can get into a home through a hole about the size of a quarter. Rats damage structure, chew wiring and cause electrical fires, eat and urinate on human and animal food and carry many diseases. Rats rely mainly on smell, taste touch and hearing because of poor vision.
Accidental poisoning could occur among humans and pets from poorly placed poison.
