Mosquito management in WA

  • There are more than 100 different mosquito species in WA.
  • Only a small number of these transmit mosquito-borne diseases.
  • A range of surveillance and management activities are undertaken throughout WA to reduce the health impacts of mosquitoes.

Only a small number of mosquitoes species found in WA bite people and transmit mosquito-borne diseases, the rest are just a nuisance. However, the species that do present a health risk tend to be the ones more commonly found in many parts of WA.

Mosquito surveillance

Mosquito surveillance is used to monitor the number and type of mosquitoes active in the environment and determine whether they are carrying viruses that can cause disease in people.

This information is used to assist local governments in their mosquito management activities and to warn the public when the risk of mosquito-borne disease transmission is higher than normal.

There are mosquito surveillance programs (external site) in both the north and south of WA, where the risk of mosquito-borne disease is highest. Some local governments also choose to do their own surveillance activities.

Mosquito management

In WA, mosquito management is also the responsibility of all landowners or land occupiers. If you are experiencing mosquito problems, first follow these simple checks to make sure you are not accidentally breeding mosquitoes around your home.

If you believe the mosquito issue is coming from a neighbouring property or a natural breeding habitat, contact your local government (external site).

Each local government authority has the primary responsibility for overseeing mosquito control within their area.

The preferred mosquito control methods (external site) will be different depending on the environment and the location in WA. Your local government environmental health team will provide you with best advice for your area.

Local government mosquito management

It is up to each local government to determine the most appropriate mosquito management measures to reduce the risk of mosquito-borne disease transmission.
