Here's the honest answer: mosquito zappers and citronella candles offer only mild, short-term relief at best, and neither one solves an actual mosquito problem. Zappers mostly attract and kill moths and other flying insects rather than mosquitoes, and citronella only masks the carbon dioxide and body scent mosquitoes use to find you and only within a metre or two of the candle. If mosquitoes are a serious problem in your backyard, these products are worth having for a barbecue, but they won't stop the bites, and they definitely won't deal with a breeding site nearby. It's a question we hear all the time here at Jim's Termite & Pest Control, so I'll break down exactly what each product does and doesn't do, and what actually gets rid of mosquitoes for good.

TL;DR — Key Takeaways

Bug zappers are largely ineffective against mosquitoes — studies consistently show they kill far more harmless insects (moths, beetles) than mosquitoes, which aren't strongly attracted to UV light.
Citronella candles work, but only in a very small radius (roughly 1-1.5 metres) and only for as long as they're burning steadily - wind cuts their effectiveness fast.
Neither product addresses the actual source — if mosquitoes are breeding nearby, you'll keep getting bitten no matter how many candles or zappers you set up.
Personal repellents (DEET or picaridin-based) outperform both for actual bite prevention, but they only protect the person wearing them.
The only way to actually reduce mosquito numbers is eliminating breeding sites and treating the yard - standing water, gutters, plant saucers and shaded damp areas are the real target.

Do Bug Zappers Actually Kill Mosquitoes?

Not really bug zappers are mostly ineffective against mosquitoes because mosquitoes aren't strongly drawn to UV light, which is what zappers use as bait.

Entomology studies looking at zapper "catch" have found that the overwhelming majority of insects killed are moths, beetles and other non-biting insects mosquitoes typically make up a small fraction of the total kill count. Mosquitoes are drawn far more to carbon dioxide (your breath), body heat and skin odour than to light, which is exactly why they find you even when a zapper is running nearby.

Where zappers can help: general flying insect nuisance around outdoor lighting. Where they fall short: actually reducing mosquito bites in your yard.

Do Citronella Candles Actually Repel Mosquitoes?

Citronella candles do work, but only within a very short range roughly a metre to a metre and a half and their effect drops off quickly in any wind or open-air setting.

Citronella oil works by masking the scents mosquitoes use to locate a host (carbon dioxide, lactic acid, body odour). Within that small radius, and while the candle is burning cleanly, it does measurably reduce landings. The catch:

Range is limited — sit further than about 1.5 metres away and the effect drops off fast.
Wind defeats it — even a light breeze disperses the scent before it can mask you.
It's a repellent, not a killer — citronella doesn't reduce the mosquito population nearby, it just makes you a little less appealing for as long as you're near the candle.

For a small, still, sheltered patio with a few people sitting close together, citronella candles genuinely help. For an open backyard with any airflow, don't expect much.

What About Citronella Plants, Coils and Diffusers?

Same principle as candles they work in a very limited radius and lose effectiveness in wind or open spaces, so treat them as a minor supplement rather than a solution.

Mosquito coils perform slightly better than candles in still conditions because they release more concentrated smoke, but the same wind and range limitations apply. Plug-in diffusers work indoors in a closed room but aren't practical for backyard use.

What Actually Works Better Than Zappers and Candles?

Personal repellents containing DEET or picaridin are the most effective short-term option, and eliminating breeding sites is the only way to actually reduce mosquito numbers around your property.

Here's how the options stack up:

The pattern here is simple: personal repellent stops bites on you specifically, and treating the property is what actually reduces the mosquito population around your home.

Why Do I Still Get Bitten Even With Repellent Products Around?

If you're still getting bitten despite candles, coils or zappers, the most likely explanation is a nearby breeding site that's constantly producing new mosquitoes faster than any backyard gadget can offset.

Mosquitoes only need a small amount of stagnant water a bottle cap's worth to breed. Common overlooked breeding spots around Australian homes include:

Blocked or poorly draining gutters
Plant pot saucers and bird baths
Unused pools, spas or water features
Tarps or covers that pool rainwater
Downpipes and rainwater tanks without proper screening

If any of these exist near your outdoor living area, you can burn every citronella candle you own and still get bitten, because new mosquitoes are hatching within metres of where you're sitting.

How Do Professionals Treat a Mosquito Problem?

Here's how our technicians at Jim's actually go about it: we identify and eliminate breeding sites on the property, then apply residual treatments to resting areas vegetation, shaded fence lines, under decking where adult mosquitoes shelter during the day.

This is the meaningful difference between a backyard gadget and professional treatment: gadgets try to repel or kill mosquitoes that have already reached you, while a proper treatment plan reduces the number of mosquitoes being produced and living on the property in the first place. That's why professional treatment holds up in windy conditions, open yards and larger properties in a way that candles and zappers simply can't.

Get Rid of Mosquitoes for Good

If backyard gadgets aren't cutting it, the issue usually isn't the products it's an active breeding site or resting area that needs professional attention. Our licensed technicians inspect the property, find where mosquitoes are actually breeding and sheltering, and apply targeted treatment that keeps working long after a candle burns out.
