Pests

Animal pests, both vertebrates (backbone) and invertebrates (no backbone), can have an adverse impact on agriculture, the natural environment and even our lifestyle. Animal pests may be exotic animals which are introduced, either accidentally or deliberately. Native animals may also be pests in certain situations.

The Department of Primary Industries and Regional Development manages pests in Western Australia through policy development, risk assessment, research and development, provision of technical advice and information, implementation of regulation, emergency response, property inspections, industry liaison, and the planning and coordination of significant species control/eradication programs.

For advice on pests search our website, the Western Australian Organism List or contact our Pest and Disease Information Service (PaDIS).

For diagnostic services, please contact our Diagnostic Laboratory Services.
