Do Citronella Candles Really Work?

If you've ever lit a citronella candle in your backyard hoping it would keep mosquitoes away, you're not alone. These candles are sold everywhere and often marketed as a natural way to repel bugs. But here's the surprising truth: citronella candles don't actually do much to stop mosquitoes.

According to a study published in the Journal of Insect Science and reported by Science.org, citronella candles had no measurable impact on mosquito behavior. Researchers tested 11 mosquito repellent products—including sprays, wearable devices, and citronella candles—using a wind tunnel designed to mimic backyard conditions. The results were clear: while DEET and oil of lemon eucalyptus sprays reduced mosquito attraction by 60%, citronella candles offered no statistically significant protection.

What does science say about citronella candles?

In the experiment, scientists placed a person at one end of a wind tunnel and used special equipment to measure how many mosquitoes moved toward them with and without various repellent products in use. At a distance of 1 meter, nearly 91% of mosquitoes still flew toward the person when a citronella candle was burning nearby. That's almost the same as when no repellent was used at all.

This means that citronella candles may smell pleasant and set the mood, but they don't do the job they claim to. They offer a false sense of security when it comes to protecting yourself or your family from mosquito bites and the diseases mosquitoes can carry.

What works better than citronella candles?

If you're serious about keeping mosquitoes out of your yard, here are some proven methods that actually work:

• Use EPA-registered repellents like DEET or oil of lemon eucalyptus
• Eliminate standing water where mosquitoes breed such as in buckets, planters, or birdbaths
• Install or repair window screens to keep mosquitoes from sneaking indoors
• Wear long sleeves and light-colored clothing outdoors
• Run fans on patios or decks to disrupt mosquito flight patterns

But even with all of these in place, mosquitoes can still find ways to thrive, especially in heavily wooded areas like Dyke, VA.
