Do Citronella Candles Really Work to Repel Insects?

It's a common belief that citronella candles repel mosquitoes and other insects. But is this belief backed by scientific evidence, or are we just placing our trust in an age-old myth?

Updated May 9, 2023 - NEW YORK TIMES Wirecutter Review

According to the latest review by Wirecutter, a part of The New York Times, citronella candles do not offer effective protection against mosquitoes or other insects. These candles are popular, especially during summer nights, but their efficacy is often overestimated.

How Citronella Candles Work (or Don't Work)

Citronella candles contain citronella oil, an essential oil derived from citronella grass. Citronella oil is known for its insect-repelling properties. However, scientific studies have shown that citronella candles do not effectively repel mosquitoes. In tests, DEET and oil of lemon eucalyptus sprays reduced mosquito attraction by up to 60% at a distance of 1 meter. These products are much more potent than citronella candles.

Personal Experiences with Citronella Candles

As someone who has used and made citronella candles, I can say that they do provide some level of repelling insects, but it is not 100%. I have never heard of them repelling animals, but they can create a pleasant ambiance for gatherings. However, their effectiveness against mosquitoes and other insects is questionable.

Alternatives to Citronella Candles

If you're looking for a better solution to repel mosquitoes, consider products that have been scientifically proven to be effective. DEET is a common and trusted repellent. Other options include oil of lemon eucalyptus and Permethrin. For those who prefer a natural approach, other essential oils such as lemongrass, lavender, and eucalyptus are known to have repellent properties.

Practical Tips for Repelling Mosquitoes

In addition to choosing the right repellent, here are some practical tips:

Bat Houses: Encourage natural pest control by installing bat houses in your yard. Bats are effective insect-eaters and can help reduce mosquito populations. Mosquito Traps: Consider using electric mosquito traps or ultrasonic devices, which can attract and kill mosquitoes. Physical Barriers: Install mosquito netting over outdoor seating areas to create physical barriers against insects. Plantings: Certain plants like marigolds, lavender, and catnip are known to repel mosquitoes.

Conclusion

In conclusion, while citronella candles may provide some relief and a pleasant scent, they are not a reliable means of mosquito repellent. For more effective protection, consider DEET or other proven repellents, and explore natural alternatives like essential oils and physical barriers. Enjoy your outdoor activities safely and without the constant presence of pesky insects.
