The brown rat (rattus norvegicus) is one of the most common pests worldwide. They live nearly everywhere that humans do, and researchers call them one of the most successful mammals on the planet. The brown rat goes by many names including: Norway rat, common rat, and sewer rat. Regardless of the name you call it, you definitely don’t want to see this rat in your home.

Characteristics of Brown Rats

Brown rats are quite large, growing up to 28 cm long (head and body) and weighing up to 500 grams. The tail of the brown rat is not quite as long as the rest of its body, but adds an additional 10-24 cm. Although they are known as brown rats, they can be brown or grey in color, and their underside is usually lighter. They also have small ears and blunt noses. Brown rats are sometimes mistaken for their smaller cousin the black rat (roof rat), but black rats have bigger ears, pointed noses, and their tails are longer than the length of their bodies.

Brown Rat Behavior

Brown rats are nocturnal creatures with excellent hearing and sense of smell. They are also great climbers, swimmers, and diggers. Brown rats build extensive burrow systems and tend to live in subsurface areas like cellars or sewers. They like to live underground because it provides temperature regulation, safety from predators, and a place to store food. Unfortunately for us, they are very adaptable and are now constant pests among humans in large urban areas, loving alleyways, sewer systems, and apartment buildings.

Brown rats are difficult to control because they reproduce so quickly. A female brown rat’s gestation is a mere 21 days, and she can have up to 14 pups in each litter. Those pups will then reach sexual maturity in only 5 weeks. When all is said and done, the brown rat population can grow from 2 to 15,000 in only one year!

Rats are omnivores, meaning that they eat both plant and animal matter. They live mostly on grains, but will eat nearly anything if needed. They are especially attracted to trash, sewage, and compost.
