Mosquito management

King tides have resulted in larger than anticipated increases in mosquito larvae populations across Moreton Bay and Brisbane. Council is currently conducting treatment programs to reduce populations, however some impact to residents is likely to remain.

Council’s mosquito management program is continuing to monitor and treat mosquitoes as required to keep their numbers as low as possible.

The success of the program 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.

Types of mosquitoes and 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.

Aerial treatments

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.

Fogging and barrier treatments

Fogging and barrier treatments are used in public areas such as reserves and parks to reduce the impact of adult mosquitoes on residents.

How residents can reduce mosquitoes

Residents can help reduce mosquito numbers by:

  • emptying any containers around the home that may contain rainwater such plant saucers, tyres, buckets, and clearing blocked gutters
  • changing the water in bird baths and pet bowls regularly
  • keeping your swimming pool chlorinated
  • creating a frog-friendly garden, stocking ornamental ponds and water features with fish
  • residents should also consider applying insect repellent if outdoors at dawn or dusk
  • products are available from most hardware outlets which will assist in reducing adult mosquito numbers around the home

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.
