To get rid of mosquitoes, remove every source of standing water where they breed, screen your doors and windows, use repellents and fans outdoors, and treat problem areas with a professional mosquito control treatment. Because mosquitoes can breed in as little as a teaspoon of water in about a week, tipping out water is the single most effective step.
Why are there so many mosquitoes around my home?
Mosquitoes need only a small amount of still water to breed, so the source is almost always close to home. Blocked gutters, pot plant saucers, buckets, tarps, old tyres, blocked drains and pet water bowls are the usual culprits. Warm, humid weather from spring through summer speeds up breeding, so numbers climb quickly around Sydney homes with damp, shaded yards.
How to get rid of mosquitoes step by step
The most reliable way to control mosquitoes is to remove where they breed and where the adults rest. Work through this checklist around your home and yard:
- Tip out standing water weekly from pot saucers, buckets, toys, tarps and wheelbarrows.
- Clear gutters and drains so water cannot pool.
- Refresh pet bowls and birdbaths every few days.
- Keep pools chlorinated and ponds stocked with fish or kept moving with a pump.
- Screen windows and doors and seal any gaps.
- Mow the lawn and trim dense shrubs where adult mosquitoes shelter during the day.
- Run outdoor fans on patios, as mosquitoes are weak fliers.
- Book a professional mosquito treatment for gardens and shaded resting areas.
For ongoing problems, a professional mosquito control treatment targets the shaded spots where adults rest and gives faster, longer-lasting results than sprays alone.
Do mosquito traps and repellents actually work?
Some methods stop mosquitoes breeding, others just keep them off you for a while. The table below compares the most common options.
| Method | How it works | Best for |
|---|---|---|
| Tipping out water | Removes breeding sites | The single most effective step |
| Screens and fans | Physical barrier, disrupts flight | Doors, windows and patios |
| DEET or picaridin repellents | Deters biting | Personal protection outdoors |
| Citronella and plants | Mild deterrent | A small help, not a fix |
| Bug zappers | Attract and kill insects | Limited impact on mosquitoes |
| Professional barrier spray | Treats resting and breeding areas | Yards with ongoing problems |
When to call a professional for mosquito control
If mosquitoes keep coming back after you have removed standing water, or if you back onto bushland, wetlands or a creek, it is worth calling a professional. A licensed technician treats the shaded areas where adults rest, checks for hidden breeding sites during a pest inspection, and can combine mosquito control with broader residential pest control for the whole property.
Are Australian mosquitoes dangerous?
Most mosquito bites in Australia are simply itchy, but some species can spread diseases such as Ross River virus and Barmah Forest virus, and health authorities like NSW Health advise reducing standing water to lower the risk. Cutting down on bites protects your family and pets, which is another good reason to keep numbers under control.
How to get rid of mosquitoes FAQ
What smell do mosquitoes hate?
Mosquitoes are put off by citronella, eucalyptus, lavender and peppermint. These help a little outdoors, but on their own they will not clear an infestation, so use them alongside removing standing water.
How long do mosquitoes live?
Adult mosquitoes usually live for about two to four weeks, but they breed quickly, so a small problem can build fast if breeding sites are left untreated.
What time are mosquitoes most active?
Most mosquitoes are most active at dawn and dusk, when the air is cooler and more humid. Avoiding still, shaded areas at these times and using repellent reduces bites.
Does one treatment get rid of mosquitoes for good?
A professional treatment knocks numbers down quickly, but mosquitoes can move in from nearby water, so ongoing prevention, like emptying standing water, keeps them from returning.
