Usually between 20-40cm in length, Norway rats are a brown to grey colour, with a blunt nose and small ears. They are often identifiable due to their tail being longer than their body. These rats can enter a hole the size of a 50c piece.
Do you have a Norway rat infestation?
Norway rats are active at night, which can make them hard to spot. They often live in subfloor areas under homes, outdoor burrows, or near chicken coops.
