Managing pests in the Park

It’s summer. You’re out taking a walk in the sunshine. The birds are chirping and the water is calm. Suddenly you feel something bite you. It’s those pesky mosquitoes again.

Unfortunately mosquitoes like to come out and play at the same time we do and 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) can particularly reach nuisance levels each year during their breeding season, which takes place in the warmer months.

No need to fret though! We’ve got a plan to keep those pests away!

We have been working with scientists from the Sydney University Department of Medical Entomology for many years to implement a proactive and extensive mosquito management program which aims to reduce pest mosquitoes in the Park and improve your comfort.

Whilst the Park’ wetlands are natural habitats for more than 40 species of mosquitoes, only one species often reaches nuisance level of populations during summer months. Our mosquito management program primarily aims to improve habitats so that pest mosquitoes cannot breed to excess proportions. Improved habitats are also beneficial to all our other aquatic life.

So how does the mosquito management program help?

Aerial and ground control spraying activities (with a bacterial larvicide containing Bacillus thuringiensis israelensis; also known as Bti) take place in some selected mangrove forest and saltmarsh areas of the parklands at Sydney Olympic Park. When the treatments occur depends on the basis of tide, rainfall, air temperature and larval stage.

The larvicide used in the control program is considered safe to people, pets, other fauna and the environment so you can keep enjoying the beautiful parklands while we undertake the treatment.
