Mosquito Helicopter Spraying Schedule

Sydney Olympic Park, like a number of other areas along the Parramatta River, contains extensive wetland and saltmarsh areas, which are natural breeding habitats for saltwater mosquitoes. 

Saltwater mosquitoes (Aedes vigilax) become a particular nuisance each year during their breeding season, which takes place in the warmer months.

Sydney Olympic Park Authority in collaboration with scientists from the Sydney University Department of Medical Entomology implements a proactive and extensive mosquito management program aimed to reduce pest mosquitoes on lands under its care to improve comfort levels for people living, visiting and working in the area.

The current mosquito management program involves aerial and ground control spraying activities (with a bacterial larvicide containing Bacillus thuringiensis israelensis; also known as Bti) in the mangrove forest and saltmarsh areas of the parklands at Sydney Olympic Park. The larvicide used in the control program is considered safe to people, pets, other fauna and the environment.  

Based on predicted tide data, mosquito helicopter treatment is expected to take place on Newington Nature Reserve Wetland between 6.30am - 9.30am during the following periods:

• Monday 19 November 2012
• Saturday 15 or Sunday 16 December 2012
• Monday 14 or Tuesday 15 January 2013
• Monday 11 or Tuesday 12 February 2013
• Monday 11 or Tuesday 12 March 2013
• Monday 1 or Tuesday 2 April 2013

These dates are subject to change depending on rainfall, temperature and tide.

Further information about mosquitoes and the management program can be found in the Mosquito Awareness and Protection flyer.
