Periodic spraying of the wetlands at Newington Nature Reserve will be carried out over the coming months as part of Sydney Olympic Park Authority's annual Mosquito Management Program.
The annual program of aerial and ground spraying is undertaken to reduce mosquito pests on lands under the Authority's care and improve comfort levels for people living, visting and working in the area, particularly Newington and Wentworth Point.
Like a number of other areas along the Parramatta River, Sydney Olympic Park contains extensive wetland and saltmarsh areas which are natural breeding habitats for saltwater mosquitoes. The Authority implements a proactive mosquito management program in collaboration with scientists from the University of Sydney's Department of Medical Entomology.
Saltwater mosquitoes (Aedes vigilax) can reach particular nuisance levels each year in the warmer months during their breeding season.
The Authority's mosquito management program involves the application of a bacterial larvicide containing Bti (Bacillus thuringiensis israelensis). The larvicide is considered safe for humans, pets and other fauna in the environment.
The program will include spraying activities in some of the mangrove forest and saltmarsh areas of the parklands at Sydney Olympic Park.
Based on predicted tide data, mosquito helicopter treatment is expected to take pace on Newington Nature Reserve Wetland between 6:30am and 10:30am during the following periods:
- Thursday 31 October (completed)
