While the most recognised pests in the urban areas are insects, rodents are of grave concern because of their natural ability to live close to and transm diseases to humans. They are also responsible for enormous loss of food and physical damages to properties and buildings. In addition to this there is also the psychological distress that they can cause to people living in their close proximity.

In Australia (and in the rest of the world) the 3 main pest species of rodents are Mus musculus (House mouse), Rattus rattus (also called Black or Roof rat) and Rattus norvegicus (also called Brown or Norway rat). However, unlike many countries Black rats are the predominant species of rats in Australia . All three species have very specific feeding habits and behaviours that need to be understood in order to put together an effective management program.
