An initial heatwave warning has been issued to affect the region from Tuesday 31 January to Saturday 4 February. For more information refer to:
Bureau of Meteorology warning summary
Council’s mosquito management program monitors and treats mosquitoes to keep their numbers as low as possible.
Its success is dependent on environmental factors including favourable tides, wind conditions and rain, and often coincides with treatments occurring in neighbouring local government areas.
Mosquitoes are mostly active in South East Queensland during the warmer months from September to April.
Council has developed a Statement of Management Intent(PDF, 2MB) for the Mosquito Management program. The purpose of this document is to articulate the approach that Council will take to manage mosquitoes across the region.
Lodge a request to provide feedback on mosquitoes in your local area, or for more information on Council’s ongoing mosquito management program.
South-east Queensland is home to many types of mosquitoes with those that cause the greatest impact for residents being:
Saltmarsh mosquitos hatch in the inter-tidal and mangrove areas of the region including Hays Inlet, Griffin, Mango Hill, Beachmere and Bribie Island.
Saltmarsh treatment areas
Freshwater mosquitoes breed in water that has pooled beside roads, in reserves, parks and residents' yards after a rain event.
Freshwater treatment area
Container breeding mosquitoes can be active during the day or night and prefer shaded area around homes. They breed in containers holding rainwater including plant saucers, tyres buckets, water tanks and blocked gutters.
Containers around the house that breed mosquitoes.
Council uses a helicopter to treat the region's inter-tidal and mangrove areas, targeting saltmarsh mosquito larvae which usually develop after rain or a tide higher than 2.45 metres. Aerial treatments are often planned to coincide with predicted tide events, although the effectiveness of helicopter treatments for saltmarsh mosquito larvae can be affected by wind and follow up rain.
Aerial treatments target larvae and not adult mosquitoes.
Fogging and barrier treatments are used in public areas such as reserves and parks to reduce the impact of adult mosquitoes on residents.
Adult mosquito treatment
Council uses a range of products for the treatment of mosquitoes throughout the region. The key active ingredients are:
Bti and S-Methoprene are used as they are eco-friendly and work in aquatic environments targeting the larval stages of the mosquito. With Bifenthrin and Phenothrin used for barrier spraying and ultra-low fogging (ULV) respectively.
You can help reduce mosquito numbers by:
Rainwater tanks can provide ideal conditions for mosquitoes and midges to breed. A gap the size of a matchstick head is enough to let mosquitoes into a tank to lay their eggs. Where possible, gaps should be covered with mosquito-proof screen or netting.
Queensland Health issued an alert following detection of Japanese encephalitis virus in Queensland. Japanese encephalitis (JEV) is a disease spread through the bite of an infected mosquito to people and animals.
For more information regarding JEV refer to Queensland Health.
