When is Mosquito Season in Your State? A Guide for Australians

Mosquitoes are a pesky part of Australian summers, and understanding when they are most active in your state can help you prepare. The right protection is key to keeping these buzzing insects at bay, and luckily, there are many options available to suit different preferences. Here’s when mosquito season hits and some helpful tips for each state.

New South Wales (NSW): November to April

In NSW, mosquito activity peaks from November to April, with warm temperatures and high humidity providing ideal breeding grounds. Areas near rivers, wetlands, and bushland tend to have the highest mosquito activity.

Victoria: September to March

In Victoria, mosquito season runs from September to March, particularly in rural areas or around water bodies. Coastal regions and wetlands see the most mosquito activity, with midges and sandflies also being common nuisances.

Queensland: October to May

Queensland’s tropical climate results in a long mosquito season, from October to May. The warm weather and frequent rainfall provide perfect breeding grounds for mosquitoes, especially near standing water and mangroves.

Western Australia (WA): Varies by Region

In WA, the mosquito season varies:

  • South West WA (including Perth): Peak mosquito activity from September to March.

  • Kimberley and Pilbara regions: Intense mosquito presence during the wet season, from January to May.

Regions with stagnant water or marshlands, such as the Swan River area, are hotspots for mosquitoes and sandflies.

South Australia: November to March

In South Australia, mosquitoes are most active from November to March, particularly near the Murray River and other freshwater bodies. Sandflies can also be a concern in coastal areas.

Northern Territory (NT): November to April

In the NT, mosquito season is concentrated from November to April, during the wet season. High mosquito populations are common near swamps, billabongs, and other standing water sources. Sandfly bites are also a common issue.

Tasmania: December to March

Tasmania experiences a shorter mosquito season, from December to March, with the highest activity occurring near wetlands, lakes, and coastal areas.

Australian Capital Territory (ACT): December to March

In the ACT, mosquitoes are most active between December and March. Areas near lakes, ponds, and nature reserves are the most affected.

General Mosquito Protection Tips

  • Use mosquito repellents: DEET-free options, natural mosquito repellents, or citronella-based sprays are effective. Consider mosquito patches or bands for portable protection.

  • Eliminate breeding grounds: Remove standing water from your property to prevent mosquitoes from laying eggs. Check gutters, birdbaths, and any containers holding water.

  • Wear protective clothing: Cover exposed skin with long sleeves and pants, especially during dawn and dusk when mosquitoes are most active.

  • Repel with plants: Plant mosquito-repellent species like citronella, lavender, or lemongrass in your garden to create a natural barrier against mosquitoes.

  • Use mosquito nets: Protect sleeping areas with mosquito nets to prevent bites at night.

  • Address sandflies: For coastal areas, sandfly bites can be avoided with similar precautions, including natural insect repellents and covering exposed skin.

Why Consider Natural and Chemical-Free Solutions?

While traditional mosquito repellents often contain chemicals like DEET, many Australians are opting for more natural alternatives. These include essential oil sprays, citronella candles, and mosquito-repellent plants. These solutions are gentler on the skin and environment, offering an eco-friendly way to stay mosquito-free.
