Mosquito management

Helicopter Treatment

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

The effectiveness of council’s treatment 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

South East Queensland is home to many types of mosquitoes with those that cause the greatest impact for residents being:

1. Saltmarsh mosquito - (Aedes vigilax)

Saltmarsh mosquitoes hatch in the inter-tidal and mangrove areas of the Moreton Bay Region including Hays Inlet, Griffin, Mango Hill, Beachmere and Bribie Island.

2. Freshwater mosquito - (Culex annulirostris)

Freshwater mosquitoes breed in water that has pooled beside roads, in reserves, parks and residents’ yards after a rain event.

3. Container breeder - (Aedes notoscripts)

Container breeding mosquitoes can be active during the day or night and prefer shaded areas around homes. They breed in containers holding rainwater including plant saucers, tyres buckets, water tanks and blocked gutters.

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.
