Candles have been used for centuries to repel insects. One of the most popular candles for this purpose is the citronella candle, which is made from an essential oil distilled from dried cultivated grasses. However, evidence suggests that citronella candles are not very effective in keeping mosquitoes away. In fact, they may do more harm to beneficial insects than mosquitoes. Other candles that may be effective in repelling insects include those infused with neem extract, peppermint oil, lemongrass oil, pine oil, and lavender oil. It is important to note that while these candles may help to keep bugs away, they are not a guaranteed solution and should be used in conjunction with other pest control methods.

What You'll Learn
Citronella candles are ineffective
While candles can be used to keep bugs away, citronella candles are not very effective in this regard. Although citronella oil, derived from dried cultivated grasses, has long been regarded as a "natural" mosquito repellent, there is no indication that citronella candles provide more protection than any other candle-produced smoke.
Essential oils, such as citronella, only block a limited number of chemical receptors in mosquitoes. In contrast, EPA-approved repellents like DEET and picaridin block a much wider range of receptors, making them more effective. Additionally, citronella candles may even attract more mosquitoes due to the increased CO2 production from burning candles.
Citronella candles are also ineffective in open areas, and their overall impact is limited to the immediate area surrounding the candle. While they may provide some protection, it is minimal and should be considered just one layer of defence against mosquitoes.
There are alternative candles with natural scents that can be more effective in keeping bugs away. For example, candles infused with neem extract are popular in America and Europe and have a calming effect due to their scent. Peppermint oil candles are another option, as their strong mentholated smell can repel not only bugs but also rodents.
Overall, while citronella candles may provide a pleasant scent, their bug-repelling capabilities are limited, and consumers should be aware of their ineffectiveness before purchasing them solely for mosquito control.

Bug-repelling candles with lavender and peppermint
While some candles claim to be bug-repelling, not all of them are effective. Citronella candles, for example, are popular for bug repellent, but they are not very effective in keeping mosquitoes away. They may provide a bug-free barrier in the immediate area surrounding the candle, but they do not offer substantial protection from bites.
If you're looking for a candle that does more than just provide ambiance and keeps bugs at bay, consider candles infused with natural essential oils like lavender and peppermint. These candles not only enhance your outdoor environment with a pleasant aroma but also act as a natural repellent for mosquitoes and other insects.
Lavender oil is an excellent choice for repelling insects. Its floral scent not only masks the chemicals that attract mosquitoes but also creates an unpleasant environment for them, encouraging them to seek other places to feed.
Peppermint oil, on the other hand, has a strong mentholated scent that bugs find irritating. Research has shown that the mentholated smell irritates the mucous membranes of mice, causing them to avoid areas where this smell lingers. This makes peppermint-infused candles a great option for repelling not just insects but also rodents.
When choosing bug-repelling candles, it's important to opt for those with natural essential oils. These provide a safe and non-toxic way to repel bugs, especially if you have young children or pets around. Additionally, look for candles with a variety of scents to enhance your outdoor environment, such as the invigorating smell of peppermint or the calming fragrance of lavender.
By lighting a few of these bug-repelling candles, you can enjoy a peaceful, bite-free experience under the stars, making your summer nights more enjoyable and relaxing.

Ultrasonic devices are a waste of money
Candles infused with natural scents, such as neem extract, peppermint oil, lemongrass, and pine oil, are often marketed as insect repellents. While these candles may provide some protection against bugs, their effectiveness varies and is generally limited to the immediate area surrounding the candle. For example, citronella candles, which are popular for mosquito control, have been found to be mostly ineffective, providing no more protection than any other candle-produced smoke.
Similarly, ultrasonic devices that emit high-frequency sounds to repel pests have been touted as a solution for bug problems. However, these devices have not been scientifically proven to work and are considered by some to be a waste of money. Here's why:
Lack of Scientific Evidence
Manufacturers of ultrasonic pest repellers often make claims that are not supported by scientific testing. In 2001, the Federal Trade Commission (FTC) sent warning letters to over 60 companies, stating that their efficacy claims must be backed by scientific evidence. Despite this, many companies continue to market their products without providing sufficient proof of their effectiveness.
Mixed Results in Laboratory Tests
Laboratory tests on ultrasonic pest repellers have shown mixed results. While some tests indicate a degree of success in repelling certain insects, such as crickets, others have found that common pests like cockroaches, ants, and spiders are largely unaffected by these devices. Even when the devices appear to work, the pests may become habituated to the noise over time, realizing it poses no threat.
Limited Real-World Effectiveness
Ultrasonic pest repellers face significant challenges in real-world environments. Signal strength can be rapidly diminished by walls, furniture, and other obstacles, reducing their effectiveness in typical household settings. Additionally, the devices may interfere with telephone conversations, burglar alarm systems, and hearing aids, raising safety concerns for certain individuals.
Alternative Solutions
Instead of relying on ultrasonic devices, homeowners with pest problems can seek advice from qualified inspectors who can help identify specific issues and recommend practical solutions. Chemical pesticides, traps, and even cats have been suggested as more reliable and inexpensive forms of pest control. For mosquito control specifically, EPA-approved repellents containing DEET or picaridin are recommended by experts as they block a wider range of chemical receptors that mosquitoes use to interpret their environment.

Natural alternatives to bug repellent candles
While candles infused with natural ingredients like essential oils are often marketed as insect repellents, evidence suggests that they are not very effective. Citronella candles, in particular, have been found to be ineffective in providing more protection than any other candle-produced smoke. This is because essential oils do not offer as substantial protection as EPA-approved repellents like DEET and picaridin.
If you're looking for natural alternatives to bug repellent candles, here are some options that can be more effective:
- Lemon eucalyptus oil: This oil, derived from the leaves of the lemon-scented eucalyptus tree, is excellent for keeping flies, mosquitoes, and mites away. However, it attracts bees, so it's better suited for urban environments without bees.
- Lavender oil: Lavender oil is effective at repelling mosquitoes, flies, gnats, bed bugs, ants, lice, moths, spiders, ticks, and fruit flies.
- Peppermint oil: Peppermint oil is a great natural repellent for fleas, spiders, ants, cockroaches, gnats, moths, wasps, stink bugs, aphids, bed bugs, fruit flies, boxelder bugs, and head lice. Its strong mentholated smell also helps keep rodents like mice away.
- Neem oil: Neem oil candles are often combined with other insecticidal essential oils like citronella. Neem oil has a calming effect through its scent and is popular in America and Europe.
- Lemongrass oil: Lemongrass oil has a stronger bug repellent effect than citronella and is often used in candles to keep insects away.
- Pine oil: Pine oil is another essential oil that repels insects. While its effect is weaker than citronella and lemongrass, it is still a good option as it can be produced in North America and Europe, reducing the carbon footprint.
In addition to these natural alternatives, there are other methods to control bugs and mosquitoes. For example, you can use bug repellent sprays, incense sticks, or electronic devices like the Thermacell E65 Rechargeable Mosquito Repeller, which uses heat to vaporize a liquid repellent and protect an area from mosquitoes.

Candles that attract bugs
While some candles can repel bugs, certain types of candles can attract bugs. Bugs are attracted to sweet and floral scents, so candles with sugary, sweet, or floral fragrances may invite insects. These smells remind bugs of food, so they fly towards them in search of a meal.
Citronella candles, on the other hand, are known for their bug-repelling properties and are commonly used in outdoor settings. However, some sources claim that citronella candles are not very effective in keeping mosquitoes away and that they only provide a limited barrier of protection in the immediate area surrounding the candle.
Other natural scents that can be used in candles to repel bugs include lavender, peppermint, lemongrass, pine, and lemon eucalyptus. It is important to note that lemon eucalyptus has the disadvantage of attracting bees, so it may not be suitable for outdoor use.
When choosing a candle to repel bugs, it is best to opt for those made with specific essential oils known for their bug-repelling properties rather than sweet or floral fragrances. Additionally, using candles in combination with other bug-repelling methods, such as eliminating breeding grounds, can help create a more effective barrier against insects.
