Brisbane City Council delivers Australia’s leading mosquito management program and remains the only Council in Australia to employ two expert entomologists. Council’s expert entomologists collaborate with researchers and other agencies to ensure we are using the best information and technology available to limit mosquito breeding in Brisbane.

Council’s mosquito management program targets two types of mosquitoes: 

  • saltmarsh mosquitoes (Aedes vigilax) which breed in coastal saltmarshes
  • freshwater-breeding mosquitoes (Culex annulirostris) which breed in temporary ground pools.

A third type of mosquito, container-breeding mosquito (Aedes notoscriptus), can be found in Brisbane’s backyards. Control of this species requires householders to be aware of breeding sites and remove or manage them. 

Council typically manage more than 20,000 hectares of saltmarsh mosquito breeding area and 2500 known freshwater mosquito-breeding sites across the city.

These sites are inspected regularly using:

  • All Terrain Vehicle (ATV) teams
  • utility trucks
  • on foot. 

The large, coastal saltmarsh mosquito breeding habitats are treated by helicopter with ground support by ATV teams.

Council’s control activities are scientifically managed, targeting specific areas where and when breeding is known to occur. The program follows industry best practice and uses products designed to kill mosquito larvae without harming people, pets and the general environment.

Council treats the saltmarsh mosquito larvae in their breeding pools before they emerge with either Bti (Bacillus thuringiensis israelensis) or methoprene based products that target the larvae and are safe for people, pets and the general environment. Bti only affects larvae for the few days before they pupate while methoprene disrupts the pupation process. This means that there are usually only a few days available, after a hatch event, to successfully control the larvae with these products.

The 'How Brisbane City Council manages mosquitoes' video contains the following open captions:

Council's saltmarsh mosquito control activities are scientifically managed.
We spray tidal wetlands, from the ground, all-year-round.
Eco-friendly sprays are used to target mosquito larvae, before they mature.
Sprays used are safe for other animals, the environment and humans.
We also treat over 20,000 hectares by helicopter each season.
Whether the helicopters can fly is weather dependent.
Strong winds or heavy rain will disrupt a treatment.
