Why Are There So Many Mosquitoes in Summer?

Mosquitoes need two things to multiply: warmth and still water. Summer in Australia brings both. Heat speeds up their life cycle, so eggs laid in a pot plant saucer can become biting adults in about a week. Summer storms then refill every container, gutter and tarp in the yard.

We also spend more time outside in summer, often at dusk when many species are most active. More people outdoors plus more breeding sites means more bites.

It's more than an itch. Mosquitoes in Australia can carry Ross River virus, Barmah Forest virus and Japanese encephalitis, so reducing them around your home protects your family's health, not just your evenings.

How Can I Get Rid of Mosquitoes in My Backyard?

The most effective way to rid mosquitoes from your yard is to take away what they need to breed and rest. These steps cost little and make a real difference when done consistently.

1. Remove Standing Water Every Week

If it holds water, it can breed mosquitoes, even something as small as a bottle cap. A weekly sweep breaks the life cycle before larvae become biters.

Your Weekly Backyard Water Checklist

  • Empty and refill bird baths and pet bowls
  • Tip out pot plant saucers, buckets and toys
  • Store wheelbarrows and containers upside down or under cover
  • Check boat covers, tarps and trailers for pooled water
  • Look for water trapped in bromeliads and similar plants
  • Re-check everything after heavy rain

2. Clear Gutters and Drains

Blocked gutters are one of the most common hidden breeding sites we find. Clear leaves from gutters, downpipes and drains so water flows away instead of sitting for days.

3. Keep Pools, Ponds and Water Features Moving

Water Feature What to Do
Swimming pool Keep chlorine balanced and run the pump daily. A green pool is a mosquito nursery.
Garden pond Add a fountain or pump, and consider native fish that eat larvae. Avoid releasing exotic "mosquitofish".
Rainwater or septic tank Fit fine mesh screens over inlets and overflows.
Unused fountain Empty and scrub it, or fill it with gravel and plants.

4. Trim Back Shade and Clutter

Adult mosquitoes rest in cool, damp, shady spots during the day. Mow regularly, prune dense shrubs to let air through, and clear leaf litter and garden waste away from outdoor seating.

5. Protect Your Outdoor Living Areas

  • Use fans: mosquitoes are weak flyers, and a pedestal or ceiling fan on the deck keeps them off course.
  • Switch your globes: warm or yellow LED lights draw fewer flying insects than bright white bulbs.
  • Screen a space: a meshed pergola or patio gives you a bite-free zone on peak nights.
  • Wear repellent: choose an APVMA-registered product with DEET, picaridin or oil of lemon eucalyptus, and cover all exposed skin.
A quick word on gadgets: bug zappers and ultrasonic devices catch very few mosquitoes, and "mosquito-repelling" plants have little evidence behind them. Spend your effort on water and shelter instead.

How to Get Rid of Mosquitoes in Your Home

Mosquitoes inside the house usually come from the yard, so outdoor control is your first line of defence. To keep mosquitoes in your home to a minimum:

  • Fit and repair flyscreens on windows and doors
  • Close doors at dusk, when activity peaks
  • Empty vases, drip trays and pet water bowls inside too
  • Use a fan or air conditioning in bedrooms

So, how do you kill mosquitoes already indoors? A household insect spray registered for mosquitoes works on contact, but it only treats the symptom. If you keep finding mosquitoes inside the house, there's likely a breeding site nearby that needs attention.

Why Professional Mosquito Pest Control Matters for a Pest-Free Yard

Good yard habits are the foundation, but they don't always win the summer. If you live near bushland, creeks or wetlands, mosquitoes can fly in from beyond your fence. Some breeding sites are also hard to spot, like roof gutters, sub-floor drains and dense garden beds.

That's where professional mosquito pest control makes the difference, reaching the problem areas DIY methods miss.

What a Professional Treatment Covers

  1. Inspection: A licensed technician finds the breeding and resting sites you may have missed. A professional pest inspection also picks up other seasonal pests before they settle in.
  2. Larval Control: Registered treatments in water you can't remove stop larvae becoming adults.
  3. Barrier Treatment: Targeted applications to foliage, fences and shaded resting areas reduce adult mosquitoes.
  4. Advice and Follow-Up: A plan for your property, timed around peak season.
