Candles have been used to repel bugs for centuries. In ancient times, people burned herbs and oils to ward off insects, eventually incorporating these natural repellents into candles. Today, candles remain a popular way to keep bugs at bay, with many modern options available. While some candles are marketed as insect repellents, their effectiveness varies. Citronella candles, for instance, are popular for their scent and mood-setting qualities, but studies have shown them to be largely ineffective at repelling mosquitoes. However, other candles infused with natural essential oils like peppermint, basil, tea tree oil, rosemary, cinnamon, neem, lemongrass, pine oil, and lavender oil have been found to be more successful at deterring insects. These candles offer a safe, non-toxic, and pleasant-smelling alternative to chemical insecticides.

Citronella candles: history, effectiveness, and alternatives
The history of citronella dates back thousands of years to ancient Asian civilisations, which burned its leaves to ward off insects and used its extracted oils in medicine for their antibacterial and anti-inflammatory qualities. Cymbopogon nardus and Cymbopogon winterianus are the plant's most common species, recognised for their aromatic and repellent characteristics. Today, citronella is still prized for its natural properties and is employed in a variety of products, notably candles, which are said to repel mosquitoes.
However, the effectiveness of citronella candles in repelling mosquitoes has been called into question by recent research. In a study testing 11 types of repellents on Aedes aegypti mosquitoes, scientists found that, at a distance of 1 meter, DEET and oil of lemon eucalyptus sprays reduced mosquito attraction by 60%, whereas citronella candles did not perform as well as advertised. The candles are said to emit a delicate fragrance that masks human odours, confusing insects and keeping them at bay, but this effect may be limited.
Citronella candles can still be useful for creating a pleasant atmosphere, even if their mosquito-repelling abilities are not as strong as other methods. For those seeking alternatives, DEET and oil of lemon eucalyptus sprays are recommended for repelling mosquitoes, with the former being the most effective option according to the study. Wearable devices that emit insect repellent are also available, though their effectiveness may vary.
While citronella candles may not be the most effective mosquito repellent, they represent a natural and sophisticated solution for those seeking alternatives to traditional insect repellents. Combining tradition with innovation, these candles offer a pleasant fragrance and potential insect-confusing properties, contributing to a comfortable and welcoming environment during summer evenings.

Natural essential oils: peppermint, basil, tea tree, rosemary, and cinnamon
Natural essential oils such as peppermint, basil, tea tree, rosemary, and cinnamon are effective bug repellents. These oils can be used in conjunction with other ingredients to create a bug repellent spray. For example, a combination of vanilla essential oil, lavender essential oil, and tea tree can be used to create a bug repellent spray. Additionally, peppermint oil can be combined with water and a few drops of dish soap to create a bug repellent solution.
Rosemary oil is a key ingredient in many bug repellent sprays, such as Wondercide, which is safe for people of all ages, including kids and babies. It is also safe to use around pets. This spray is gentle yet effective in repelling flying pests and preventing bug bites.
Tea tree oil is another effective bug repellent. It can be applied to the skin after dilution, as direct application is not recommended. One user reported that applying tea tree oil cream after shaving kept bugs away.
Similarly, peppermint oil is a well-known natural bug repellent with pest-repellent properties. It can be used as a DIY pest repellent solution by mixing 10 to 20 drops of peppermint essential oil with one cup of water. However, it is important to note that peppermint oil is not long-lasting and may need to be reapplied frequently.
Basil is another essential oil with a high effectiveness rate in repelling bugs. It can be combined with other oils like lemongrass and geranium to enhance its bug-repelling properties.
Cinnamon oil is also mentioned as an effective bug repellent, although specific details on its usage are not provided in the sources.

DIY bug-repellent candles: choosing essential oils and creating scented candles
Bug-repellent candles are a great way to keep insects away without exposing yourself to harmful chemicals. Many people opt for natural bug sprays and citronella candles to reduce the chances of getting bitten. You can also make your own scented candles with essential oils to keep pests at bay.
Choosing essential oils
When choosing essential oils for your bug-repellent candles, there are several options known for their insect-repelling properties. These include:
- Citronella
- Lemongrass
- Rosemary
- Geranium
- Lavender
- Patchouli
- Peppermint
These oils can be combined to create a woodsy scent that is not only pleasing to humans but also effective at repelling mosquitoes and other insects. For example, a combination of rosemary, geranium, and lavender oils can be used, or you can opt for citronella if you prefer.
Creating scented candles
To create your own scented candles, you will need a few simple ingredients and tools:
- Beeswax
- Essential oils
- Wicks
- Containers (such as recycled cans or glass jars)
- Double boiler

The advantages of candles over chemical sprays and electronic bug zappers
The use of candles as bug repellents has been a practice for centuries. In ancient times, people would burn herbs and oils to ward off insects, recognising the power of scent in keeping bugs at bay. Candles have several advantages over chemical sprays and electronic bug zappers when it comes to repelling insects.
Firstly, candles are a natural alternative to chemical insect repellents. The demand for natural solutions like scented candles has grown due to the harmful effects associated with certain chemicals. For example, bug zappers, also known as electronic insect-control systems, lure bugs and kill them with electricity. However, they have been criticised for their indiscriminate killing of insects, which can disrupt pollination and harm the environment. Bug zappers are also ineffective against mosquitoes and other biting flies, which are often the insects that people want to target.
Secondly, candles are easy to use and transport, making them ideal for various outdoor activities such as camping trips, picnics, or any outdoor adventure. Their portability ensures that you can create a bug-free zone wherever you go. On the other hand, chemical sprays may require direct application to the skin or clothing, which can be inconvenient and may not provide long-lasting protection.
Thirdly, scented candles offer the dual benefit of light and protection. They can enhance the ambiance of outdoor spaces while naturally repelling insects. Certain scents, such as peppermint, basil, tea tree oil, rosemary, and cinnamon, are particularly effective at deterring mosquitoes and other insects due to their strong aromas. While citronella candles are popular for bug repelling, there is limited evidence of their effectiveness compared to other candle scents or EPA-approved chemical repellents.
Lastly, candles can provide a more pleasant sensory experience compared to chemical sprays and electronic bug zappers. Some people may prefer the aroma of scented candles over the strong chemical smell of sprays or the sound and sight of zapping bugs. Overall, candles offer a more subtle and natural approach to bug repelling, which can be especially appealing for those seeking a less intrusive method.

Other natural alternatives to candles for repelling bugs
Candles made from natural essential oils are a safe and non-toxic way to repel bugs. They are especially beneficial for families with young children and pets. However, if you are looking for other natural alternatives to candles for repelling bugs, there are several effective options:
Essential oils
Applying essential oils directly to the skin is a natural way to repel bugs. Oils such as tea tree oil, peppermint oil, and citronella oil are known for their bug-repelling properties. These oils can also be diluted and sprayed into the air or onto fabrics.
Herbs and Spices
Burning herbs, such as basil and rosemary, produces a sharp, spicy aroma that is unpleasant to mosquitoes and other insects. Similarly, cinnamon is a strong, spicy scent known to deter insects, including mosquitoes, ants, and even spiders.
Natural Repellents
Natural bug repellent sprays are an alternative to candles. For example, a spray made from oil of lemon eucalyptus can reduce mosquito attraction by 60%.
Soy Wax
Soy wax is a natural, long-burning, and biodegradable alternative to candles. Soy wax blended with essential oils can be an effective bug repellent while also providing a pleasant aroma.
These alternatives offer similar benefits to candles, such as portability and safety, while also providing natural bug-repelling properties. They can be used individually or in combination to create an effective barrier against insects during outdoor activities or quiet evenings at home.
