Citronella candles are candles that contain citronella oil, a naturally occurring insect and animal repellent distilled from two grass varieties. They are often used to repel mosquitoes. However, there is no indication that citronella candles provide more protection than any other candle-produced smoke. In fact, some sources claim that citronella candles are ineffective at repelling mosquitoes. While citronella oil is generally considered non-toxic in solid form, there are some concerns about its potential toxicity when burned or applied to the skin. It is important to follow label instructions and take steps to minimize exposure to citronella products.

What You'll Learn
Citronella candles are non-toxic in solid form
Citronella candles are made from an essential oil derived from the leaves and stems of lemongrass. This oil is a naturally occurring insect and animal repellent and has been used for centuries to control mosquitoes. It is also used in cosmetics, incense, and other candles.
While citronella is a natural and non-toxic substance in solid form, there are some concerns about its potential toxicity when burned and inhaled. It is important to note that mosquito candles, in general, pose a fire hazard and are not intended for indoor use. To avoid potential risks, these candles should be placed on non-flammable surfaces.
The toxicity concerns regarding citronella products are primarily related to repellent concoctions applied to the skin or ingested. People can be exposed to chemicals if they come into contact with the substance through their skin, eyes, or ingestion. It is recommended to always follow label instructions and take steps to minimize exposure.
Additionally, the fumes from citronella oil have been said to be potentially toxic to birds, especially when used in conjunction with other essential oils in air fresheners. However, there is limited evidence to support these claims. Studies have shown that citronella does not alter or damage genes, and one of its main components, geraniol, has been observed to reduce the growth of certain cancers.
While citronella candles are non-toxic in solid form, their effectiveness as mosquito repellents has been questioned. Some studies have concluded that these candles do not provide more protection against mosquitoes than any other candle-produced smoke. Other repellents, such as picaridin and DEET, are considered more effective in blocking mosquito receptors.

Burning citronella candles may cause harm
Citronella candles are poisonous to dogs and can lead to stomach cramping if ingested. The American Society for the Prevention of Cruelty to Animals lists citronella candles as toxic to dogs. The fumes from burning citronella candles are also potentially toxic to birds. The smoke from these candles poses a fire hazard, and they should not be placed near flammable materials like mulch, fencing, or wooden decks.
In addition, the effectiveness of citronella candles in repelling mosquitoes is questionable. While citronella oil is a natural mosquito repellent, it may not provide adequate protection compared to EPA-approved repellents like DEET and picaridin. Mosquitoes interpret their environment through multiple chemical receptors, and essential oils like citronella only block a limited number of these receptors. As a result, mosquitoes may not be effectively deterred by citronella candles.
The potential health and safety risks associated with burning citronella candles underscore the importance of proper use and caution. It is crucial to follow label instructions and take necessary precautions to minimize exposure, especially for children, pets, and individuals with allergies or respiratory sensitivities. While citronella candles may offer some mosquito-repelling benefits, prioritizing safety and exploring alternative, EPA-approved repellents is advisable.

Citronella oil is toxic to birds
It is important to note that citronella candles and oils are not the same thing and may have different effects on birds. Citronella oil is listed by the EPA as being "practically nontoxic" to birds. This includes hummingbirds. Oil of citronella is a naturally occurring insect and animal repellent distilled from two grass varieties. It is a mixture of many components, the main ones being citronellol, citronellal, and geraniol.
However, it is important to keep in mind that if birds come into direct contact with the oil, it could be harmful. Birds should not ingest citronella oil, and it should not be allowed to get on their feathers. If birds come into contact with the oil, follow the First Aid instructions on the product label carefully. For additional treatment advice, contact the Poison Control Center.
Citronella candles, on the other hand, are intended for outdoor use only and can be toxic to all animals if ingested, including chickens. The amount ingested will determine whether it will kill them. However, one person reported that their chickens ate a citronella candle and did not get sick. In this case, milk was used as a flush to clean out the toxins, but it is not recommended to let the milk sour for too long.
While citronella oil is generally considered safe for birds, it is always important to use these products with caution and follow the instructions on the label to minimize exposure and potential harm.

Citronella is not an effective mosquito repellent
While citronella candles are not considered to be poisonous, they are not an effective mosquito repellent.
Citronella is an essential oil derived from the leaves and stems of lemongrass. It is used in cosmetics, incense, and candles. The oil from the citronella plant does have mosquito-repelling properties, but there are other plants that are more effective. The plant contains citronellal, a chemical that bugs don't like, and which gives the plant its distinctive lemony scent.
However, studies have shown that citronella is not an effective mosquito repellent. A study that tested 11 types of repellents on Aedes aegypti mosquitoes—the vectors of Zika, yellow fever, dengue, and other diseases—found that citronella was not effective. The report, published in the Journal of Insect Science, showed that citronella was unsuccessful at repelling mosquitoes, along with bracelets containing herbal extracts and sonic mosquito repellers.
The Center for Disease Control does not include citronella on its list of recommended mosquito repellents, despite the fact that it is often marketed as one. The CDC recommends oil of lemon eucalyptus spray, which has been shown to reduce mosquito attraction by 60%.
While burning anything will repel mosquitoes, as they are deterred by the smoke, the citronella scent does not work to deter them.

Citronella oil is a natural insect repellent
Citronella oil is known to be effective in repelling insects rather than killing them. It works by masking scents that are attractive to insects, making it difficult for them to locate their target. This quality of citronella oil makes it safer for bees and other pollinators, as they are less likely to be harmed. While it is considered safe for humans, some people may experience skin irritation or allergic reactions when using citronella oil as an insect repellent. It is recommended that citronella oil be diluted in a carrier oil or lotion before being applied to the skin.
Additionally, it is important to note that children may be especially sensitive to pesticides. Citronella oil products should not be used on children under six months of age unless directed by a doctor. Inhalation of citronella oil vapors is generally not recommended and may cause lung damage. Ingesting citronella oil is also not advised, as there is limited research on its safety for human consumption, and there have been reports of poisoning in children who consumed insect repellent containing citronella oil.
While citronella oil is a natural and effective insect repellent, it may not be as potent as other synthetic repellents like DEET. Studies have shown that citronella oil provides mosquito protection for up to three hours when combined with vanillin, while DEET offers over 90% protection for more than six hours. However, citronella oil does offer additional benefits, such as antifungal properties that can help weaken or destroy certain types of fungi that are harmful to human health.
