What You'll Learn

Citronella candles repel flies due to their scent
Citronella candles are popular outdoor fly repellents. The strong scent of the citronella plant acts as a natural deterrent to flies, with the smoke released from the burning candles carrying the scent and helping to keep flies away.
Citronella oil, derived from the leaves of certain Cymbopogon species, contains natural compounds that emit a strong aroma that flies find unpleasant. The scent masks the attractants that might otherwise draw flies to an area. The potent smell of citronella can also confuse flies' sensory receptors, making it difficult for them to locate food sources or suitable places to land.
Citronella candles are widely available and can be burned on your patio or in areas where flies are a problem. They are considered safe for humans and animals when used as directed, but it is important to follow proper usage guidelines and ensure proper ventilation to avoid excessive inhalation of the scent.
In addition to candles, citronella can also be used as a fly repellent in essential oil diffusers, DIY sprays, and by growing the citronella plant around your home. These methods can help create an environment that is pleasant for you and unwelcoming to flies.

Burning candles can deter flies
Flies can be a nuisance, especially during the summer when they seem to multiply by the second. Not only are they a persistent presence, but they can also transmit diseases such as salmonella and E. coli. While there are various methods to keep flies away, one popular suggestion is the use of candles, specifically citronella candles.
Citronella is an essential oil derived from dried cultivated grasses and has long been considered a "natural" mosquito repellent. It is available in various forms, including candles, oils, and diffusers, all claiming to repel insects. Citronella candles, in particular, are marketed as an effective way to keep flies at bay.
The effectiveness of citronella candles in repelling flies is a subject of debate. Some sources claim that the strong citrusy scent of citronella is unpleasant to flies, and the smoke and flame of the candle further deter them. As a result, burning these candles can drive away flies and create a bug-free environment.
However, other sources argue that citronella candles are not as effective as they are marketed to be. While the scent may overwhelm flies and cause them to stay away temporarily, it is not a long-term solution. Additionally, the scent may not spread far enough to cover large areas, and pairing it with other methods may be necessary.
While burning citronella candles may provide some relief from flies, it is essential to combine it with other fly-repelling strategies. Keeping your surroundings clean, using natural repellents like vinegar, and employing traps or fans can help create a more comprehensive defence against these pesky insects.

Natural fly repellents
Flies are a common nuisance, especially during the summer. While candles, especially citronella candles, can be effective outdoor fly repellents, there are several other natural remedies that can help keep flies away.
Herbs and Flowers
Herbs and flowers such as basil, bay leaf, cedar, cinnamon, citrus, citronella, cloves, lavender, marigolds, mint, rosemary, and peppermint are effective at repelling flies. These can be planted around the house or placed on countertops.
Cleanliness
Keeping your surroundings clean is crucial in preventing fly infestations. This includes cleaning garbage cans, removing animal feces, and properly storing garbage. Additionally, flies are attracted to standing water, so ensure that any standing water is dumped.
Natural Sprays
Several natural sprays can be made at home to repel flies. One recipe includes mixing witch hazel, apple cider vinegar, and eucalyptus essential oil. Another option is to mix vodka, aloe vera juice, eucalyptus oil, and an essential oil of your choice. These sprays can be applied to the skin or surfaces where flies are a problem.
Venus Flytraps
Venus flytraps are carnivorous plants that naturally attract and eat flies. Planting them outdoors can help reduce the fly population.
Light Refraction

Other Repellents
- Tea tree oil: Effective in repelling most insects.
- Pine-Sol: Its scent is known to repel flies.
- Fans: Flies are not strong flyers, so placing a fan on your porch can help keep them away.

Other methods to keep flies away
While candles can help keep flies away, there are several other methods to try as well.
Keep Your Surroundings Clean
Flies are attracted to decaying matter, so keeping your surroundings clean is essential. This includes regularly cleaning your garbage cans, drains, and any areas where animals have relieved themselves.
Use Natural Repellents
Flies dislike certain strong scents, such as citronella, lavender, rosemary, catnip, and basil. You can try planting these herbs near your doorways or using essential oils with these scents in a bug repellent spray. Additionally, you can burn dried used coffee grounds in a shallow metal dish, creating a pleasant smell for humans but an effective repellent for flies and other bugs.
Hang Bags of Water
Hanging bags of water in sunlight can help keep flies away by reflecting light off the water and causing distress to the flies, although this method may be less effective with larger numbers of flies.
Use Fly Traps
Fly traps can be effective, but it's important to place them away from the areas you want to keep fly-free. You can use store-bought traps or make your own with sugar water.
Use Light Strategically
Flies are attracted to certain types of light, so using the right kind of lighting can help keep them away. Avoid white outdoor lights, as these can attract flies. Instead, opt for yellow light bulbs, which have been shown to repel flies.
Create Air Movement
Flies are not fond of fast-moving air, so using a box fan when spending time outdoors can help keep them at bay.
