What You'll Learn
Flies are attracted to strong floral or fruity odours
Flies are attracted to a variety of scents and odours, and it is important to know what attracts them to keep them away. Flies are pollinators and are drawn to strong, sweet scents, especially those that indicate sources of sugar and nectar.
Candles, like perfume, sometimes have strong floral or fruity odours that can attract flies. These scents may be reminiscent of overripe or ripening fruit, which flies are drawn to as they release certain volatile compounds that attract fruit flies. Mild smells will work better than strong floral smells to deter flies.
Flies are also attracted to the scent of decaying organic matter, such as rotting food, garbage, and animal waste. The odours released from these materials signal potential food sources for flies. Other strong odours that attract flies include the smell of grease, which is reminiscent of old food, and the scent of yeast, which is used in many fermentation processes.
To keep flies away, it is recommended to use repellents like citronella, which has a strong, citrusy aroma that is effective at deterring flies. Citronella can be used in candles, sprays, diffusers, or on surfaces to provide prolonged protection against flies.

Yeasty fermentation attracts flies
While candles can attract flies due to their strong floral or fruity odour, it is not just the candles that attract flies. Yeasty fermentation, for example, is a major attractor of fruit flies. Fruit flies are sensitive to sucrose-fermenting yeast, which produces a chemical that attracts them. This is due to a gene in the yeast that causes it to emit a strong odour. The yeast penetrates fruit with torn skin and then ferments it, creating an ideal environment for flies to lay their eggs.
This attraction is a result of a symbiotic relationship between the yeast and the flies. Yeast is relatively immobile, so it benefits from the ability to hitch a ride on flies to new fruit. In turn, the flies are attracted to the fermentation byproducts of yeast, such as isoamyl acetate, and use yeast as a nutritional source.
The attraction is so strong that brewers have noted an abundance of fruit flies in their beer, which is caused by the fermentation process. This has led to a new trend called "wild fermentation," where microbes spontaneously colonize the batch to create a more local flavour.
To avoid attracting flies, it is best to avoid strong floral or fruity smells, as well as to maintain proper hygiene and avoid overwatering plants.

Flies are drawn to body odour
Flies are attracted to a variety of odours, and while they are well-known for their affinity for rotting food and garbage, they are also drawn to body odour. Body odour, or bromhidrosis, is the sharp and pungent smell that can emanate from human skin and perspiration. This odour is particularly enticing to flies due to the presence of bacteria and yeast on the skin.
The human body is home to a diverse range of bacteria, some of which are responsible for the characteristic odour of body odour. These bacteria break down proteins and oils on the skin, releasing volatile compounds that contribute to the distinct smell. Additionally, the human skin is also a habitat for various yeast species, which further add to the complexity of body odour.
Flies, with their exceptional olfactory abilities, are highly sensitive to these odours. They possess the remarkable capacity to detect odours from great distances, and their sense of smell is intricately linked with their memory. The mushroom body, a pair of structures in the fly's brain, plays a crucial role in their olfactory senses. This allows flies to not only identify the presence of body odour but also to associate it with potential sources of food and breeding sites.
The attraction of flies to body odour can have significant implications for human health and sanitation. Flies are known vectors of disease, and their presence near human habitats can increase the risk of transmitting pathogens. Therefore, it is essential to address the issue of body odour, whether through improved hygiene practices or the use of deodorants and perfumes that mask or eliminate the odour. By understanding the connection between body odour and flies, we can implement effective measures to reduce fly infestations and maintain better overall hygiene.

Flies are a threat to health and comfort
Flies are a common household nuisance, but they are more than just a minor irritation. These pests pose a serious threat to your health and comfort in several ways.
Flies are drawn to a variety of smells that signal potential food sources. They are attracted to rotting food, trash, and sewage smells from toilets, septic tanks, and open sewer valves. Animal waste, dog food, and cat food are also enticing to flies, especially if they have a strong smell. Even your perfume or deodorant could be attracting flies, especially if it has a strong floral or fruity fragrance.
The presence of flies in your living space can significantly impact your comfort and quality of life. The constant buzzing and swatting can be frustrating and annoying. Flies can also contaminate your food with germs and diseases, including serious illnesses like typhoid fever and tuberculosis.
To protect your health and restore your comfort, it is essential to take proactive measures to keep flies away. Maintaining a clean home is crucial, as flies are less likely to be attracted to tidy, odour-free spaces. Regularly clean your drains with vinegar or a drain cleaner, and promptly pick up and discard any pet waste.
In addition to cleanliness, certain scents can be powerful tools for repelling flies. Strong-scented candles, diffusers, sprays, or plants can be used to deter flies from your living spaces. Citronella, pine, lavender, peppermint, and eucalyptus are all effective fly-repelling options. For outdoor areas, consider planting herbs like basil, rosemary, and lavender to create a natural barrier against flies.
By understanding what attracts flies and utilising appropriate repellent methods, you can effectively minimise the presence of these pests in your home and protect your health and comfort.

Scents that repel flies include pine, lavender, and peppermint
Flies are attracted to strong floral or fruity scents, including those from candles or perfume. However, there are several scents that repel flies. These include pine, lavender, and peppermint, all of which have pleasant aromas for humans but are hated by flies.
Pine oil, for example, has been shown to effectively deter the common housefly. In a study by Environmental Entomology, researchers found that 95% of flies avoided a honey-based solution treated with pine oil.
Lavender, a herb with a calming and pleasant scent, is also effective in deterring flies. You can use lavender oil, dried lavender bunches, or lavender sachets, which can be placed in cupboards or closets for long-lasting fly protection.
Peppermint, with its strong menthol smell, is another popular, natural, and effective repellent for flies. Peppermint oil can be used indoors, while planting peppermint in your garden or around high-traffic outdoor areas can help keep flies away from your home.
In addition to these three scents, other natural fly repellents include basil, rosemary, rue, eucalyptus, bay leaves, and citronella. Many of these scents can be used in essential oil blends or as indoor/outdoor plants to help keep flies at bay.
