There are almost 100 species of mosquitoes in Western Australia, and many can be serious pests, some can be vectors of disease. Mosquitoes breed in standing water in natural and man-made wetlands, as well as a range of water-holding containers in urban environments. They can breed in fresh, brackish and saline water conditions and different mosquito species have different habitat requirements. Some mosquito species can disperse many kilometres from breeding sites.

Mosquito Management
Having a number of public areas suitable for mosquito breeding the City is involved with on-going monitoring and management of known mosquito breeding sites. Together with other respective local governments and State Government departments, the City’s Environmental Health Services takes a proactive approach in managing mosquito breeding in neighbouring wetland areas as best as practicable.

In urban environments mosquitoes breed in water-holding containers such as pot plant drip trays, septic and water tanks, roof gutters, ponds and car tyres. The removal or maintenance of these sites can permanently reduce mosquito numbers in backyard situations.

The City regularly receives complaints regarding mosquito breeding from stagnant pool and ponds. Under the City’s Health Local Laws the owner or occupier of a premise is obligated to prevent and remove water sources liable to breed mosquitoes. Should you suspect mosquito breeding from a site within the City of Nedlands please provide written advice to the Environmental Health Section via or by post to PO Box 9, Nedlands, WA 6909.

Zika Virus

Zika virus infection causes an illness known as Zika virus disease which includes symptoms such as a mild fever, rash, conjunctivitis and muscle or joint pain. Local transmission of the virus doesn't occur in WA. However, travellers to regions where it has been reported should take care to avoid being bitten by mosquitoes. For more information see the Zika Virus fact sheet in the downloads below.

Personal Protection
Individuals have responsibility for management of mosquitoes on their own property and for protecting themselves and their families from mosquito bites. Residents can mitigate their exposure to mosquitoes by:
•    Avoiding areas of high mosquito activity, especially around dawn, dusk, and the first few hours after sunset
•    Wearing protective (long, loose-fitting) clothing when outdoors
•    Using a personal repellent containing diethyl toluamide (DEET) or picaridin. The most effective and long-lasting formulations are lotions or gels. Most natural or organic repellents are not as effective as DEET or picaridin
•    Ensuring infants and children are adequately protected against mosquito bites, preferably with suitable clothing, or other forms of insect screening. Only infant-strength repellents should be used on small children
