What Essential Oils Get Rid of Flies? Discover 5 Effective Natural Solutions

Flies are more than just a nuisance; they're a persistent problem in many households. However, the solution might lie in nature's bounty: essential oils.

What essential oils keep flies away?

Several essential oils can effectively keep flies away due to their strong, repelling scents. Some of the most commonly used essential oils for this purpose include peppermint oil,  citronella oil, eucalyptus oil, and lavender oil. Peppermint oil emits a refreshing and minty fragrance that flies find unpleasant, while citronella oil is well-known for its ability to repel insects, including flies, with its lemony scent. Eucalyptus oil has a strong, camphor-like aroma that flies tend to avoid, and lavender oil's sweet and floral scent can deter them as well.

To create a natural fly repellent, you can mix a few drops of these essential oils with water in a spray bottle and apply it to areas where flies are a problem, helping to keep them at bay without resorting to chemical insecticides.

How do you make essential oil spray to repel flies?

To make an essential oil spray to repel flies, you'll need a few simple ingredients. Start by filling a spray bottle with distilled water, leaving some room at the top for the other ingredients. Next, add about 10-15 drops of essential oils known for their fly-repelling properties, such as lavender, eucalyptus, peppermint, or citronella.

You can use a single oil or a combination of these oils for a more potent effect. Once the oils are added, close the spray bottle and shake it well to mix the ingredients thoroughly. To use, simply spray the solution in areas where flies tend to gather, like around windows, doors, or outdoor seating areas. Reapply as needed, and enjoy a natural and pleasant way to keep flies at bay without the use of harmful chemicals.

Does peppermint oil get rid of flies?

Peppermint oil is known for its strong and pleasant scent, which can act as a natural repellent for flies. When used in a concentrated form or mixed with water and sprayed in areas where flies are a nuisance, peppermint oil can help deter these pesky insects. Its aromatic properties are believed to confuse and repel flies, making it less likely for them to linger in treated areas. However, it's important to note that while peppermint oil can be an effective natural solution to help keep flies at bay, it may not completely eliminate a fly infestation on its own. Combining peppermint oil with other fly control methods, such as proper sanitation and the use of fly traps, can yield better results in managing fly problems.
