Mosquitoes

Mosquitoes are a fact of living in the wet and dry tropics of Queensland. It is important residents are familiar with how to manage mosquitoes around the home and to defend themselves against Dengue Fever and Ross River Fever.

Managing Mosquitoes

Mosquitoes require only a small quantity of water to breed. During the wet season, dengue mosquito eggs can develop to mature adults within one week. Even a cup full of water can provide adequate water for some mosquitoes to lay their eggs.

There are three main actions you can take around your home or workplace to control the breeding of mosquitoes.

Tip It: Regularly inspect potential pooling sites, such as tarps, pot plants, gutters, and buckets. Empty out any accumulated water.

Secure It: Ensure that tanks and other storage structures are adequately protected to prevent mosquitoes from accessing and laying eggs where possible. Monitor ‘open’ locations, and consider applying anti-larval substances.

Throw It: Be vigilant in responsibly disposing of rubbish, such as tyres, that could potentially form mosquito habitat.

Controlling mosquitoes in swimming pools and spas

Swimming pools and spas that are not properly maintained can become the ideal breeding grounds for mosquitoes.

Why Pools and Spas attract Mosquitoes

Mosquitoes lay their eggs in still, stagnant water. Unused or poorly maintained pools and spas provide the perfect environment for larvae to thrive.

Tips to prevent Mosquito Breeding

To reduce the risk of mosquito breeding:

  1. Maintain Your Pool or Spa
    • Keep water clean and circulating using a functioning pump and filtration system.
    • Chlorinate regularly to prevent mosquito larvae from surviving.
    • Remove debris like leaves, as they provide shelter for mosquito larvae.
  2. Cover When Not in Use
    • Use a tight-fitting pool or spa cover when the facility is not in use.
    • Make sure covers are not sagging or collecting rainwater on top.
  3. Empty and Store Properly. If the pool or spa is not in use:
    • Drain and dry it completely, or
  4. Regular Inspections

Inspect the area weekly for signs of mosquito larvae (small, wriggling insects near the water surface). Ensure all pool and spa components (like filters, skimmer boxes, and pipes) are not holding stagnant water.
