Citronella candles are a popular choice for those looking to repel mosquitoes, especially during the summer months. They are made from wax and citronella oil, which is distilled from grass and acts as a natural mosquito repellent. While these candles can be an effective way to keep mosquitoes at bay, their effectiveness is limited to the immediate area surrounding the candle. In addition, their longevity depends on various factors, including the type of wax used and how they are stored. Paraffin wax, for example, can last for five years or more, while soy wax candles should be used within a year. Proper burning and storage techniques can also impact the longevity of citronella candles.
| Characteristics | Values |
|---|---|
| Effectiveness | Citronella candles are moderately effective at repelling mosquitoes but only in the immediate area surrounding the candle. |
| Duration | Products with a citronella base are only effective as a mosquito repellent for about two hours. |
| Storage | Well-kept paraffin candles can last 5 years or longer. Well-stored soy candles should be used within a year. |

What You'll Learn
Citronella candles are made from wax and essential oils
Essential oils are derived from plants through heat distillation, solvent-based extraction, or cold pressing. Citronella oil, in particular, is distilled from two types of grass and is a naturally occurring oil that repels insects. It is currently approved as safe for humans and the environment by the U.S. authorities. Other essential oils that can be mixed with citronella oil in candles include lemon, eucalyptus, and lavender. These oils can create an uplifting or relaxing atmosphere, depending on your preference.
When making citronella candles, it is important to note that wax has a memory. Therefore, during the first burn, it is recommended to let the candle burn long enough to melt the wax across the entire diameter of the container. This helps maintain an even burn throughout the life of the candle. For example, if you have a 3-inch diameter candle, the first burn should last for about 3 hours.
While citronella candles are popular for mosquito control, their effectiveness is questionable. Citronella candles only provide protection in the immediate area surrounding the candle, and the concentration of citronella oil in candles is typically low, reducing their effectiveness. Field studies have shown that using candles only reduces mosquito bites by about half. Therefore, it is recommended to use citronella candles in conjunction with other mosquito repellent methods, such as fans, mosquito-repelling plants, or EPA-approved repellents.

Paraffin wax candles can last for five years or more
Citronella candles are popular for repelling mosquitoes, although they are not very effective. They are typically made from paraffin wax, a low-grade petroleum wax that is stable and holds a better hot and cold scent throw than its natural counterparts. Paraffin wax candles can last for five years or more if they are well-maintained.
To extend the life of a paraffin wax candle, it is important to store it correctly. Keep the candle in a cool, dry, dark place, such as a closed cabinet or closet, and avoid extreme temperatures. Sunlight, in particular, can cause the candle to lose its fragrance and discolour. An airtight container can also help to preserve the scent.
The fragrance of a candle can also be maintained by burning it correctly. When lighting a candle, it is important to allow the wax to melt across the entire diameter of the candle. This can help to prevent tunnelling, where a shell of unmelted wax forms around the outside of the candle. Burning the candle for long enough to achieve a full melt will ensure that the fragrance oil is distributed evenly throughout the wax.
Over time, candles can become discoloured or develop a rancid smell. This does not necessarily mean that the candle is unsafe to burn, but it may burn less evenly and have a weaker fragrance. To test whether an older candle is still usable, gently scratch the surface and check for a scent. If the candle has lost its fragrance, it may have passed its prime.
Paraffin wax candles can last for many years, but it is important to inspect them regularly for any signs of degradation. By following proper storage and burning techniques, you can maximise the lifespan of your citronella candles and enjoy their fragrance and mosquito-repelling properties for longer.

Soy wax candles should be used within a year
Citronella candles are popular for repelling mosquitoes, although they are not very effective in keeping mosquitoes away. They are made from different types of wax, including paraffin, soy, and beeswax. Paraffin is the most common type of wax used in commercial citronella candles, and it can last for five years or more if well kept.
Soy wax is processed from soybeans and is considered one of the cleanest-burning candle waxes available. It is denser than paraffin wax, which makes it harder for the fragrance to be released. Soy wax candles also burn slower than paraffin wax candles because the melting point of soy wax is lower.
To ensure the best quality and fragrance of soy wax candles, it is important to store them properly. They should be kept upright and on a stable surface to prevent the wax from pooling and the wick from becoming crooked. Additionally, soy wax candles should be used within a year of purchase.
The longevity of a soy wax candle also depends on various factors such as wick size, jar size, and the candle's first light. A larger container requires a bigger wick, while a smaller container needs a smaller wick to keep the melt pool shallow. Properly wicked and burned soy wax candles can burn for approximately 6 hours per ounce.

The first burn should last for one hour per inch of the candle's diameter
The first burn of a citronella candle is important as it can affect the way the candle burns subsequently. It is recommended that the first burn should last for one hour per inch of the candle's diameter. This is because wax has a memory and this step is important for all candles. For example, if you have a 3-inch diameter candle, the first burn should last about 3 hours.
Citronella candles are often used outdoors, so it is important to protect the flame from added oxygen from a breeze. A subtle breeze will improve the oxygen and add fuel to the flame, but a stronger breeze will extinguish it. A hotter flame will burn the candle too quickly, resulting in the fragrance evaporating prematurely and the wax being consumed quicker than necessary.
Citronella candles are popular for keeping mosquitoes away. They are made from a naturally occurring oil that repels insects and is distilled from two types of grass. However, they are not very effective in keeping mosquitoes away and only offer protection in the immediate area surrounding the candle.
Citronella candles are also used indoors, although it is recommended to keep pets away from them. When using citronella candles indoors, it is important to place them 18 inches apart to maximize their effectiveness.

Citronella candles are ineffective at repelling mosquitoes
While citronella candles are a popular choice for those looking to keep mosquitoes at bay, they are unfortunately not very effective in keeping mosquitoes away.
Citronella candles are moderately effective at repelling mosquitoes, but only in the immediate area surrounding the candle. The closer you are to the candle, the less likely you are to be bitten by a mosquito. However, this does not prevent mosquitoes from entering your yard or multiplying.
In a study, it was found that spray-on repellents containing N,N-Diethyl-meta-toluamide and p-menthane-3,8-diol were the most effective in repelling mosquitoes, while the citronella candle had no effect. This suggests that citronella candles do not reduce mosquito attraction to humans.
To effectively control mosquitoes, a targeted, multipronged approach is necessary. This includes eliminating all sources in which mosquitoes breed and using different repellents. For example, you can treat potential breeding grounds of water with a larvicide that kills mosquito eggs. Additionally, fans and mosquito-repelling plants can help keep mosquitoes away when you're outdoors.
While citronella candles may provide some level of protection against mosquitoes, they should not be relied upon as the sole method of mosquito control. It is recommended to use citronella candles in conjunction with other mosquito repellents to create a more effective barrier against these pests.

Frequently asked questions
Citronella candles are typically made from paraffin wax, which can last 5 years or longer when stored properly. However, the effectiveness of these candles as mosquito repellents is questionable, as the oil evaporates quickly and only provides moderate protection in the immediate area surrounding the candle.
The type of wax used in a citronella candle can impact its longevity. While paraffin wax can last for years, soy wax candles should be used within a year as they have a shorter shelf life.
When first burning a citronella candle, it is important to allow the wax to melt across the entire diameter of the container, which can take about 1 hour per inch of diameter. This helps prevent the formation of an unmelted wax shell around the outside of the candle.
To extend the lifespan of your citronella candle, consider using a candle-safe shade or jar to protect the flame from added oxygen, which can cause the candle to burn too quickly and consume the wax faster.
Citronella candles are not the only option for mosquito control. Other methods include using fans, mosquito-repelling plants, bug sprays, and electronic mosquito repellents.
