Mosquitoes

Mosquito borne viruses are major causes of human sickness and death worldwide. There are almost 100 species of mosquitoes in Western Australia. Aside from carrying disease, mosquitoes are a nuisance, interfering with amenity and outdoor activities.

The main viruses transmitted by mosquitoes in WA are Ross River Virus and Barmah Forest Virus. These illnesses may have a serious impact on the health of those that contract them and can cause painful or swollen joints, sore muscles, skin rashes, fever, fatigue and headaches. There are no cures or vaccines for these viruses so it is important that people take care to prevent being bitten by mosquitoes.

Currently the Shire of Augusta Margaret River does not have an active mosquito management program. We are gathering data on mosquito numbers with a view to undertaking regular surveillance and assessment of breeding sites in the future.  If you have concerns regarding increased mosquito numbers around the Shire, you are urged to contact the Environmental Health Unit by phoning 9780 5255.

Avoid being bitten

If you live in, or are visiting areas within the Shire, please take note of the following precautions to avoid being bitten:

• whenever possible, avoid being outdoors during times of increased mosquito activity, such as at dawn and dusk;
• wear loose fitting clothing;
• wear clothing that is light coloured;
• wear clothing that covers arms and legs;
• apply insect repellent. The most effective repellents contain either diethyl toluamide (DEET) or picaridin;
• natural or organic repellents are generally not as effective as DEET or picaridin and may need to be applied more frequently;
• the best protection for babies and young children is protective clothing, bed nets or other forms of insect screening.  Only infant-strength repellents should be used on young children.

Reduce mosquito breeding around the home

• dispose of all containers which hold water;
• stock ornamental ponds with mosquito-eating fish e.g. goldfish. Keep vegetation away from water's edge;
• keep swimming pools well chlorinated and filtered, and free from leaves;
• level or drain depressions in the ground that hold water;
• fit mosquito-proof covers to vent pipes on septic tanks systems.  Seal all gaps around the lid and ensure leach drains are completely covered;
• screen rainwater tanks with insect proof mesh, including inlet, overflow and inspection ports. Ensure guttering is not blocked and does not hold water;
• empty pot plant drip trays once a week or fill with sand.  Empty and clean animal and pet drinking water bowls once a week;
• Ensure that insect screens are installed and maintained.
