Mosquitoes

Mosquitoes are prevalent in most parts of the world, the East Kimberley is not an exemption. The East Kimberley provides a perfect environment for mosquito breeding, particularly with the high rainfall and increased temperatures experienced during the wet season. These insects can be the carriers of diseases which have adverse effects on human life.

Mosquito Management

The Shire undertakes mosquito management activities in accordance with the Shire of Wyndham East Kimberley Mosquito Management Plan (MMP), which was adopted by Council in August 2016.

The MMP has been developed in consultation with the WA Department of Health Medical Entomology team. In September 2015 a review of the Shire’s mosquito management activities was conducted by a Medical Entomologist from the Northern Territory. The recommendations from this review were also incorporated into the MMP. A copy of this report is available here

The Shire currently takes the following actions to address the risk of mosquito borne illness:

  • Participation in the Sentinel Chicken program
  • Monitoring of adult mosquito populations
  • Monitoring mosquito-borne infectious disease notifications
  • Monitoring mosquito breeding sites and application of larvicide where necessary
  • Application of residual adulticide to public areas

Spraying of adulticide (fogging) may also be used when disease risk is high.  This decision is made in consultation with the Department of Health Medical Entomology team.

If you are experiencing problems with mosquitoes at your home or workplace and wish to have an officer investigate please complete a Mosquito Nuisance Complaint Form. If you have any questions or require further information about mosquito management, please contact an Environmental Health Officer on 9168 4100.

Fight the Bite

Residents of the Kimberley region are being encouraged to 'Fight the Bite' as part of a ‘Healthy WA’ campaign to reduce the mosquito population and the incidence of mosquito-borne disease. The Fight the Bite campaign (Healthy WA) is aimed at reducing mosquito-borne diseases that afflict individuals, communities and the healthcare system.

The three central messages are to:

  • cover up
  • repel (use repellent)
  • clean up areas around the home where mosquitoes can breed.

Other precautions that can be taken to avoid mosquito bites are:

  • Avoiding outdoor exposure from dusk and at night in all areas of high mosquito activity;
  • Ensuring insect screens are installed and completely mosquito-proof: use mosquito nets and mosquito-proof tents.
  • Ensuring infants and children are adequately protected against mosquito bites, preferably with suitable clothing, bed nets or other forms of insect screening.

Refer to the Department of Health information sheet ‘Mosquitoes in Your Backyard’ for some ways to keep your property free of mosquito breeding areas.

Mosquito Bourne Diseases

The most common mosquito-borne diseases in WA are Ross River virus and Barmah Forest virus, which can lead to tiredness, severe joint swelling and pain that can continue for weeks, months or even years. Other less common diseases which are present in the Kimberley include Murray Valley encephalitis virus and West Nile virus (Kunjin subtype).

Other mosquito borne diseases include the Zika, dengue, chikungunya and yellow fever viruses. These viruses are transmitted by the Aedes aegypti mosquito. WA does not have local populations of Aedes aegypti mosquitoes and there is currently no risk of local transmission for these exotic mosquito-borne diseases in WA.

These diseases are typically present in tropical countries and any WA travellers to these regions should take personal protective measures to avoid being bitten by mosquitoes. Travellers should seek medical advice or consult smarttraveller.gov.au before travelling to high risk countries.

Further information on protecting yourself from mosquito-borne disease while travelling can be found at the Healthy WA website.

Sentinel Chicken Program

The University of Western Australia runs a sentinel chicken program which is carried out by local governments. The program works as an early indicator of mosquito borne disease activity in the area. Blood samples are taken from a flock of chickens in Wyndham and Kununurra every month in the dry season and every fortnight in the wet season.

The samples are analysed for both West Nile virus (Kunjin subtype) and Murray Valley Encephalitis. The detection of either of these viruses indicates prevalence of the disease in the area and gives a ‘heads up’ to the public so extra precautions can be taken to minimise risk of the disease.
