Candles are a great way to set the mood and create a cozy atmosphere, but do they attract bugs? The short answer is that it depends on the type of candle and the scent. Some candles, especially those with sweet or floral fragrances, can attract mosquitoes and other insects. Bugs are attracted to a variety of scents, and certain candles can inadvertently invite unwanted insect guests. However, there are also candles that are specifically designed to repel bugs. These candles typically contain essential oils or extracts such as citronella, lavender, peppermint, and eucalyptus, which insects find repellent. While candlelight can draw insects' attention at night, choosing the right type of candle with natural bug-repellent scents can help control pests and create a more enjoyable environment.

What You'll Learn

Scented candles can attract bugs
Scented candles are often believed to be the best way to keep bugs away. However, this is not always the case. While some scents can repel insects, others can attract them. Bugs are attracted to a variety of scents, and some, like bees and wasps, have a good sense of smell. They can differentiate between a wide range of smells.
Sweet, floral, or fruity scented candles, for instance, can attract mosquitoes and other insects. This is because bugs are drawn to anything that smells good to them, be it sweet, sour, or spicy. Therefore, it is best to avoid using scented candles with such fragrances, especially outdoors, as they may invite unwanted insects.
On the other hand, certain scented candles can help keep bugs at bay. Candles infused with essential oils like lavender, peppermint, eucalyptus, lemongrass, tea tree oil, and lemon eucalyptus extract are effective at repelling mosquitoes and other pests. Citronella, a common herbal extract used in insect repellent candles, can also deter mosquitoes, gnats, and flies. However, it is important to note that citronella candles may not be as effective as other mosquito repellent methods, and they may attract bees.
To effectively keep bugs away, it is recommended to use candles made with specific bug-repelling essential oils rather than sweet or floral fragrances. Additionally, proper placement of these candles can help reduce bug infestations.

Bug-repelling candles work
While candles with sweet or floral scents can attract bugs, there are bug-repelling candles that work effectively to keep insects away. Bug-repelling candles typically contain essential oils such as lavender, peppermint, eucalyptus, lemongrass, and tea tree oil, which are known to repel mosquitoes and other pests. These candles are a great choice for outdoor use, especially when combined with strategic placement.
Lavender, for example, is an effective repellent against mosquitoes, flies, gnats, bed bugs, ants, lice, moths, spiders, ticks, and fruit flies. Peppermint is also a powerful repellent for a wide range of insects, including fleas, spiders, ants, cockroaches, gnats, moths, wasps, stink bugs, aphids, bed bugs, fruit flies, boxelder bugs, and head lice. Tea tree oil is particularly useful against head lice, bed bugs, and dust mites.
Citronella candles, a popular choice for mosquito repellence, have been found to be ineffective. A study from the University of Delaware showed that out of 13,789 insects killed by bug zappers, only 31 were biting flies, including mosquitoes, which is a negligible percentage. Instead, EPA-approved repellents like DEET and picaridin are more effective, as they block a wider range of receptors that mosquitoes use to interpret the world.
In addition to bug-repelling candles, other methods to keep mosquitoes at bay include using a simple fan, as mosquitoes are weak fliers, and spatial repellent products like the Thermacell E65 Rechargeable Mosquito Repeller, which uses heat to vaporize a liquid repellent.

Natural bug repellents
Candles with sweet or floral scents can attract bugs, especially mosquitoes, due to the odours from the fragrances used. However, some candles can help repel insects. Candles made with essential oils such as lavender, peppermint, eucalyptus, lemongrass, tea tree, and citronella can be effective at keeping mosquitoes and other pests at bay.
There are also several natural bug repellents that can be used as an alternative to candles. Many of these repellents use natural oils from ingredients like garlic, thyme, lemon eucalyptus, lemon, dill, and citronella. These oils are known to repel insects such as mosquitoes, ticks, fleas, and ants. For example, a 2022 study found that lemon eucalyptus oil can repel mosquitoes for up to six hours. However, it's important to note that not all essential oils are safe for topical use and some, like citrus oils, can be phototoxic when applied directly to the skin.
Other natural bug-repelling solutions include peppermint oil, which has been shown to repel several insects, including mosquitoes, ants, flies, lice, and spiders. Apple cider vinegar may also help, although more research is needed to confirm its effectiveness. Additionally, a simple fan can be an effective tool against mosquitoes, as they are weak fliers, and circulating air can prevent them from reaching you.

Essential oils block chemical receptors
Candles with sweet or floral scents can attract bugs, while candles with certain essential oils can help keep them away. However, it is important to note that essential oils may not be the most effective bug repellent. While they do work by blocking the chemical receptors in insects, they only block a limited number of these receptors.
Mosquitoes, for example, interpret the world through multiple chemical receptors. These receptors are tuned to odors, taste, heat, and humidity. Repellents like picaridin and DEET block a much wider number of receptors on a more consistent basis, thus offering better protection.
Essential oils, on the other hand, can interfere with the proper functioning of neurotransmitters in insects. They can also affect the insects' highly sensitive respiratory system, causing irritation or paralysis of their respiratory muscles, which can lead to respiratory distress and affect their overall nervous system function.
Some essential oils that can be used as insect repellents include peppermint, lemongrass, cedarwood, lavender, tea tree, and lemon eucalyptus essential oil. These oils can be applied directly to the skin (diluted with a carrier oil), diffused, or mixed with water to create a bug spray. However, it is important to exercise caution when using essential oils, especially around people, pets, and outdoors.

Outdoor lighting attracts bugs
While candles can attract bugs, the focus here is on outdoor lighting and its role in attracting insects.
Outdoor lighting can indeed attract bugs, and this is due to several reasons. Firstly, certain types of light bulbs, such as traditional incandescent bulbs, emit a significant amount of heat and ultraviolet (UV) light, which are highly attractive to insects. The UV light emitted by these bulbs can confuse some insects, disrupting their natural navigation systems. Nocturnal insects like moths, for instance, use the moon and stars as reference points to navigate, and the presence of unnatural light sources can cause them to veer off course. Additionally, the warmth and specific wavelengths of light produced by incandescent bulbs make them particularly alluring to moths, beetles, and other insects.
To reduce the attraction of bugs to outdoor lighting, it is recommended to switch to bulbs that emit less UV and blue light. Warm LED bulbs, for example, produce minimal heat and UV light. Instead, they emit light in the yellow and orange spectrum, which is less visible and appealing to most insects. These bulbs have been found to attract fewer bugs compared to other types of light bulbs.
Another strategy is to install motion-activated lights, which can be triggered by human movement rather than by bugs. Moving the location of light fixtures and using spotlights placed away from areas where bugs are likely to gather can also help reduce their presence.
It is worth noting that not all insects are repelled by the same lighting configurations. Some insects are still sensitive to yellow light, so even "bug-proof" lights may not be entirely effective. The effectiveness of different lighting options can vary depending on the specific types of insects prevalent in a given area.
