Mosquito breeding increases after rain or flooding, and it is important that residents help prevent outbreaks of mosquito-borne disease.

Make sure you wear insect repellent if you are being bitten. When cleaning up your house and yard following a cyclone or flood, get rid of potential mosquito breeding sites to prevent outbreak of mosquito-born disease.

Rain or floodwater may have collected in containers around your yard, so make sure you empty them and store them in a dry place or throw them away.

Controlling Mosquitos After Wet Weather

Floods often lead to increased mosquito numbers which can lead to an increase in bites and the potential for an increase in mosquito-borne disease. Standing water from heavy rainfall and flooding provides perfect conditions for mosquito breeding.

You need to play your part and help reduce the number of potential breeding sites by taking the following actions in and around your home.

Actions to take:

When cleaning up your house and yard following a cyclone or flood, get rid of potential mosquito breeding sites to help prevent mosquito-borne disease.

Remove any stagnant pools of water around your house and yard. This may involve clearing debris from ditches, cutting small channels to help pooling water drain, or filling in holes and vehicle wheel ruts.

Clean up debris which the flood waters have deposited on your property. While a lot of this debris may be half buried, it often contains enough water to breed large numbers of mosquitoes. In addition to pooled water, rain or floodwater may have collected in containers around your yard, so make sure you tip them out and store them in a dry place, or throw them away.

Common mosquito breeding sites include:

  • pot plant bases (inside and outside)
  • tyres
  • tarpaulins
  • palm fronds
  • buckets
  • tin cans and plastic containers
  • boats
  • coconut shells
  • roof gutters (if blocked by leaf debris).

Rainwater tanks can also be a source of mosquitoes.

  • check the mosquito screens and flap valves on rainwater tanks, particularly in-ground tanks to ensure that the screens and flap valves are still in place.
  • Make repairs as necessary.

Avoid being bitten

  • wear insect repellent whenever mosquitoes are present
  • wear long, loose, light-coloured clothing
  • use flying insect spray to kill any mosquitoes in rooms
  • use mosquito coils or plug-in insecticide mats in rooms
  • repair defective insect screens.

See a doctor immediately if you become unwell with fever, headache, skin rash, joint or muscle pain.
