Citronella candles are widely marketed as an effective way to repel mosquitoes. However, their effectiveness has been called into question by various sources, including scientific studies. While some people find them moderately useful in reducing mosquito bites in the immediate area surrounding the candle, others have found them to be completely ineffective, with mosquitoes being drawn to the candle or human breath instead. So, do all citronella candles repel mosquitoes? The answer is more complex than a simple yes or no.

Citronella candles are moderately effective at repelling mosquitoes in their immediate vicinity
Mosquitoes are a common pest, especially during the summer months, and can be dangerous as they spread diseases such as the West Nile virus, Zika, yellow fever, and dengue. While there are many mosquito repellent products on the market, not all of them are effective. One popular option is citronella candles, which are made from an oil derived from the leaves and stems of a cousin of lemongrass. The oil has a light citrus scent that is pleasant to most humans but purportedly disliked by mosquitoes. However, the effectiveness of citronella candles in repelling mosquitoes is questionable.
Some sources claim that citronella candles are only moderately effective in repelling mosquitoes in their immediate vicinity. The closer you are to the candle, the less likely you are to be bitten. This limited effectiveness means that citronella candles should be considered just one layer of protection against mosquitoes, rather than a standalone solution. Additionally, citronella candles do not prevent mosquitoes from entering a yard or multiplying.
The moderate effectiveness of citronella candles may be due to the fact that mosquitoes interpret the world through multiple chemical receptors. EPA-approved repellents like DEET and picaridin block a wider number of these receptors, making them more effective repellents than citronella. In a study testing 11 types of repellents on Aedes aegypti mosquitoes, DEET and oil of lemon eucalyptus sprays reduced mosquito attraction by 60%, while citronella candles had a weak repellent effect.
Furthermore, many citronella candles on the market do not contain real citronella but a substitute. Humans cannot tell the difference, but mosquitoes can, and the fake stuff has no effect on them. This may contribute to the varying levels of effectiveness reported by different users of citronella candles. While some people find that citronella candles help to reduce mosquito bites, others find that they do nothing to repel mosquitoes and can even attract them due to the CO2 produced by the candle.
Overall, while citronella candles may offer some protection against mosquitoes in the immediate area surrounding the candle, they are not a foolproof solution. For more effective mosquito repellent options, individuals can consider EPA-approved repellents like DEET and picaridin, which are designed to block a wider number of mosquito receptors.

DEET and lemon eucalyptus oil are more effective repellents
Citronella candles are a popular choice for those looking to ward off mosquitoes. However, their effectiveness in keeping these insects away is questionable. While they can provide some protection in the immediate area surrounding the candle, they are not a foolproof solution.
For those seeking more reliable mosquito repellents, DEET and lemon eucalyptus oil are worth considering. DEET, or N,N-diethyl-meta-toluamide, is a well-known and widely used active ingredient in insect repellents. It has been proven effective and safe when used as directed. DEET-based products come in various forms, including lotions, sprays, and sticks, making it convenient for users to choose their preferred application method.
Lemon eucalyptus oil, on the other hand, is a natural, plant-based alternative. It is the only plant-based ingredient recommended by the CDC for mosquito repellent. This oil is extracted from the leaves of lemon eucalyptus trees and contains an active ingredient called para-menthane-3,8-diol (PMD), which effectively repels mosquitoes and other insects. Lemon eucalyptus oil has been shown to provide a similar level of protection against mosquitoes as DEET, making it a viable option for those seeking a natural repellent.
In terms of safety, DEET has undergone extensive testing and is considered safe when used as directed. While lemon eucalyptus oil may not have the same level of safety data, it is generally considered low risk when used according to label instructions. However, it is important to note that lemon eucalyptus oil should not be used on young children and should be kept away from the eyes to avoid irritation.
Both DEET and lemon eucalyptus oil offer effective and reliable mosquito repellent options. When deciding between the two, consider your preference for a synthetic or natural product, as well as your specific needs and concerns regarding safety and ease of application.

The citronella plant and oil are marketed as repellents but are ineffective
Citronella candles are mostly ineffective at repelling mosquitoes. While they may provide a small amount of protection in the immediate area surrounding the candle, they do not offer a substantial shield against mosquitoes. This is because essential oils do not block the same number of receptors as EPA-approved repellents such as DEET and picaridin.
A study testing 11 types of repellents on Aedes aegypti mosquitoes found that citronella candles were ineffective. DEET and oil of lemon eucalyptus sprays reduced mosquito attraction by 60%, while the citronella candle had a weak repellent effect.
The citronella plant (Pelargonium graveolens) and the grass used to produce the oil (Cymbopogon genus) have not proven to be effective in repelling mosquitoes, despite being marketed as such. Many gardeners believe that the citrus scent from the plant will repel mosquitoes, but this is untrue.
Other mosquito-fighting products such as repellent bracelets and ultrasonic devices are also ineffective and can be a waste of money. The most effective mosquito repellents are EPA-approved products containing ingredients like DEET, picaridin, and oil of lemon eucalyptus.

Some mosquito repellents are toxic to cats, bees, and fish
While citronella candles are a popular mosquito repellent, they are only moderately effective, deterring mosquitoes in the immediate area surrounding the candle. For greater protection, it is recommended to use bug repellent sprays or wearables containing DEET or lemon eucalyptus oil.
However, some mosquito repellents are toxic to cats, bees, and fish. Citronella, for example, is considered toxic to cats and dogs in almost all forms, including candles, oils, and plants. Ingesting citronella can cause gastrointestinal issues in cats, while applying it to the skin can cause irritation.
Essential oils, such as tea tree oil, are also toxic to cats and can cause upset stomachs, central nervous system depression, and even liver damage. Other essential oils, like geranium oil, can cause contact dermatitis if applied to the skin and irritation to the mouth if ingested.
Some common bug sprays and mosquito repellents for humans contain DEET, which can be very toxic to cats and dogs, leading to vomiting, staggering, seizures, and other serious issues. It is important to avoid using these products on pets and to ensure they do not lick or come into contact with treated skin.
While lavender is effective at repelling mosquitoes, it contains linalool, which can be toxic to dogs and cats if ingested in large quantities. Peppermint plants are also effective mosquito repellents but should be kept out of the reach of dogs and cats, as consuming large amounts can lead to vomiting and diarrhea.
To protect cats from mosquitoes, it is recommended to use heartworm preventative medication and broad-spectrum flea and tick medication. Flea-Ex by Two Crazy Cat Ladies is an example of a natural and safe product for both humans and cats.
