Citronella candles are often marketed as a natural mosquito repellent, but there is little evidence to support their effectiveness in this regard. However, some people believe that citronella may also be effective in repelling other insects, including spiders. While there is some anecdotal evidence to support this claim, it is important to note that the primary purpose of citronella candles is to set a mood or create a pleasant aroma, and they may not be completely effective as a sole means of pest control.

What You'll Learn
Citronella oil repels mosquitoes
While citronella candles are widely believed to repel mosquitoes, scientific studies have shown that they are ineffective in doing so. However, citronella oil, which is derived from the leaves and stems of a cousin of lemongrass, has been found to be a natural mosquito repellent.
Citronella oil works by masking scents that are attractive to mosquitoes, making it difficult for them to locate their target. It is important to note that citronella oil does not kill mosquitoes but rather repels them. This makes it a safer option for bees and other pollinators, as they are not likely to be harmed.
The effectiveness of citronella oil as a mosquito repellent has been compared to other repellents like DEET and fennel oil. In a 2015 study, DEET had a protection rating of over 90% over six hours, while citronella oil offered protection of about 57% after only two hours. This highlights the need to reapply citronella oil more frequently to maintain its effectiveness.
To use citronella oil as a mosquito repellent, it can be added to water in a glass spray bottle or diffused using a diffuser. It can also be diluted with a carrier oil or lotion before being applied to the skin. However, it is important to exercise caution when using citronella oil, as it can cause skin irritation or allergic reactions in some individuals, especially children.
While citronella oil may not be as effective as other mosquito repellents, it offers a more natural alternative for those who prefer to avoid chemical-based products. It is also important to note that no single solution to mosquito control works 100% of the time, and a combination of methods may be necessary to effectively deter mosquitoes.

Spiders dislike the smell of citronella
While citronella candles are advertised as mosquito repellents, their effectiveness is questionable. However, they do seem to repel spiders. Spiders dislike the smell of citronella and will avoid areas with this oil. This makes citronella candles a good option for those looking for natural spider repellents.
Citronella is an essential oil distilled from dried cultivated grasses. It has long been regarded as a "natural" mosquito repellent and is sold in various forms, including candles, essential oil diffusers, and tiki torches. However, studies have shown that citronella candles may not be as effective as other mosquito repellents like DEET and picaridin.
Despite the mixed evidence on its mosquito-repelling capabilities, citronella appears to be effective against spiders. Spiders seem to have an aversion to the smell of citronella, and adding a few drops of citronella essential oil to candles or air filters can help keep them away. This makes citronella a useful tool for those looking for natural ways to reduce the number of spiders in their homes.
In addition to citronella, other natural spider repellents include lemon dust cleaner and salt. Dissolving salt in warm water creates a saline mixture that can be sprayed directly onto spiders or their nests to eliminate them. While spiders have their benefits, not everyone wants them as house guests, and using natural repellents like citronella can help keep them at bay.
It is worth noting that while citronella may not be the most effective mosquito repellent, it can still be useful in combination with other methods. For example, using mosquito netting or screens in conjunction with citronella candles can provide a more comprehensive mosquito control solution. Additionally, circulating air with a simple fan can also help keep mosquitoes away, as they are weak fliers.

Salt water is a natural spider poison
While citronella candles are often marketed as mosquito repellents, they are not very effective at keeping mosquitoes away. In fact, there is no evidence that they provide more protection than any other candle.
If you're looking for a natural way to get rid of spiders, salt water is a great option. Salt is a natural type of spider poison and can be used to create an effective pest control spray. Mixing salt with water creates a saline solution that can be sprayed directly onto spiders, their nests, and egg sacs. This solution is particularly effective on thinner-skinned spiders and immature spiders.
To make your own spider control spray, mix one ounce of table salt with a gallon of warm water. It's important to use warm water so that the salt fully dissolves. Once the salt is dissolved, pour the solution into a spray bottle and apply it directly to the spiders, nests, and egg sacs you want to eliminate. You can also spray this solution around the perimeter of your home to create a barrier that will prevent spiders from entering.
Salt water is an effective spider repellent because it is a slowly acting toxin that can harm spiders and cause dehydration. When the saltwater solution comes into contact with a spider, it draws out moisture from the spider's body, leading to dehydration. This makes salt water a great option for removing spiders from your home without having to resort to harsh chemicals.
However, it's important to note that salt water can be harmful to plants, so be careful not to spray it on flowers or other plants. Additionally, the salt in the solution may leave traces on surfaces, so avoid spraying it directly on delicate or valuable items.

Mosquitoes are weak fliers
While citronella candles may help repel mosquitoes, they are not the most effective method. A more surprising, low-tech solution is to use a fan. Mosquitoes are weak fliers, so a simple fan can effectively deter them.
Mosquitoes are considered weak fliers because many species weigh only about 2.5 milligrams and do not fly above 25 feet. A fan set on high speed can prevent mosquitoes from landing on you by blowing wind in their direction. Additionally, a fan reduces body heat and sweat, which mosquitoes use as sensory information to locate their prey.
To keep mosquitoes at bay, set up a small electric fan that rotates back and forth, creating a gentle breeze in the area you are occupying. This method was tested by a group of people at a barbecue surrounded by greenery—perfect conditions for mosquitoes. However, no mosquitoes flew into the vicinity of the fan-generated wind, and no one was bitten.
While fans can be an effective, low-cost solution, they may not be practical in all situations. For example, if you are camping or attending a sporting event, you may want to consider a spatial repellent product like the Thermacell E65 Rechargeable Mosquito Repeller. This product uses heat to vaporize a liquid repellent, creating a bug-free barrier around you. However, spatial repellent products can lose effectiveness in windy conditions, so they may not be the best choice if you are in a breezy area.
In addition to fans and spatial repellents, there are other ways to keep mosquitoes away. One unusual method is to spray Listerine around your outdoor space, as some people have found that mosquitoes dislike the scent. You can also try using mosquito netting or screens to create a physical barrier, or apply a repellent recommended by the Centers for Disease Control and Prevention to prevent mosquito bites.

EPA-approved repellents are more effective
While some people may opt for natural insect repellents, such as citronella candles, these are not always effective. In fact, a study that tested 11 types of repellents on mosquitoes found that citronella candles did not live up to their promises. Instead, EPA-approved repellents are more effective at keeping insects at bay.
EPA-approved repellents have undergone rigorous safety and efficacy testing and can, therefore, be trusted. The approval process for repellent chemicals is extensive and includes findings from the Centers for Disease Control and Prevention and the World Health Organization. EPA-registered repellents have provided technical information on their safety and effectiveness against mosquitoes and/or ticks, based on scientific testing guidelines and approved study methods.
One such EPA-approved repellent is picaridin, which is considered safe and effective. It comes in a bottle that sprays evenly and accurately, without the downsides of DEET, which can be messy and leave a residue on the skin. Sawyer Products' 20% Picaridin Insect Repellent is one such example, offering the same protection as Ranger Ready's repellent.
For clothing and gear, Sawyer's permethrin repellent is effective at repelling ticks and mosquitoes, with a trigger spray that is easy to control. The Thermacell E65 Rechargeable Mosquito Repeller is another example of an effective repellent. It uses heat to vaporize a liquid repellent, protecting an area from mosquitoes.
In summary, while natural repellents like citronella candles may be preferred by some, EPA-approved repellents are more effective. These products have undergone extensive testing and are, therefore, reliable in protecting against mosquitoes and ticks.
