Norway rat (Rattus norvegicus)
Known as either sewer rat, brown rat, or wharf rat, this rat is the larger species. In fact, adult Norway rats can weigh about half a kilo! They are active at night and are both good swimmers and diggers. They’re omnivores, too, and that means they eat plant and animal matter. Their staple diet includes meat, fish, vegetables, cereals, weeds, earthworms, nuts, fruits, and even crustaceans.

Roof rat (Rattus rattus)
Often called a ship rat or black rat, it is smaller than the Norway rat. They’re usually found in roofs of homes and buildings, and ships and known for their incredible climbing ability. They can be recognised by their black/brown fur and their tail that is as long as their head and body combined. They eat anything with nutritional value and although they are omnivorous, they will feed on meats and insects when grains, fruits, and cereals are scarce.

House mouse (Mus musculus)
While not a rat, the house mouse is often mistaken for one due to its similar behaviour and presence in homes. It has a small, slender body, large ears, and a long, thin tail. They’re curious and highly adaptable animals and can often be found in close proximity to human settlements. They have a varied diet that consists of grains, fruits, animal feeds, cereals, and nuts.

House mouse (Mus musculus)
This is the most common mouse species in Australia. House mice are small, with grey or brown fur, and are often found in homes, farms, and businesses. They are highly adaptable and can thrive in various environments.

Field mouse (Apodemus Sylvaticus)
There are several species of native Australian field mice, but they are less common than the house mouse. You’ll find these mice in rural areas. They are usually more shy and less likely to invade homes.
