#1 Citrus

Bursting with lively aroma, citrus fruits are a favorite in many households. Beyond their taste, citrus fruits offer an unexpected benefit—they’re highly effective in repelling flies.

Why Flies Hate Citrus

The acidic, sharp smell of citrus fruits is overwhelming for flies and something they hate. Both houseflies and fruit flies exhibit a pronounced distaste for this scent. Unlike us, who find citrus fragrances refreshing, flies find them strong and off-putting.

The Prominence of Lemons and Oranges

Of all the citrus varieties, lemons and oranges are particularly effective in repelling flies. They give off a robust citrus aroma, and their peels contain d-Limonene, an insect-repelling compound.

Using Citrus as a Fly Repellent

Citrus fruits provide a versatile arsenal for repelling flies. You can scatter fresh peels of oranges or lemons in areas where flies frequent. Placing them around windows, doors, and other entry points helps ward off these insects.

Another effective method uses citrus essential oils. Put a few drops on a cotton ball and position it in areas where flies gather. Alternatively, you can make a simple citrus spray by mixing water and a few drops of citrus essential oil. This spray can be applied around your home to deter flies.

Planting citrus trees or shrubs in your garden also helps keep flies away. The constant presence of the citrus aroma repels flies and maintains a comfortable outdoor environment.

#2 Basil

Basil is a culinary delight across the globe. Its vibrant flavor and fresh aroma grace countless dishes. This beloved herb, however, holds another less-known advantage – it’s an excellent fly deterrent.

Why Flies Hate Basil

Flies find the strong aroma of basil quite disagreeable. This pungent herb emits a volatile compound that disrupts the flies’ olfactory receptors, resulting in an environment they wish to avoid. This aversion is rooted in the flies’ survival instincts to evade plants that could potentially be harmful.

The Superiority of Sweet Basil

Among the wide array of basil types, sweet basil is particularly potent in repelling flies. Its distinct and robust aroma provides an effective barrier against these bothersome pests.

Using Basil as a Fly Repellent

Incorporating basil into your fly deterrence strategy is both practical and efficient.

One simple method involves positioning potted basil plants near entry points like windows and doors or even on kitchen counters. The basil’s ongoing aroma release will create a fly-repelling environment.

You can also assemble small bouquets of fresh basil leaves and place them around your home. As the leaves dry, they emit their unique, fly-deterring scent.

Basil essential oil offers another method for fly deterrence. Placing a few drops on a diffuser or on cotton balls scattered around your home will keep the flies at bay. Because even though you love the smell, flies will hate it.

#3 Lavender

Lavender is a cherished plant celebrated for its striking purple blooms and soothing scent. It’s widely used in aromatherapy, cosmetics, and even in cooking. But it also holds a less well-known benefit—it’s a highly effective fly deterrent.

Why Flies Hate Lavender

While lavender’s fragrance is calming to humans, flies have a completely different reaction. The potent aroma, which comes from the essential oils present in the plant, is repellent to flies. This strong scent overwhelms their sensory perception, making it uncomfortable for them to remain in its vicinity. It smells lovely to us but flies absolutely hate it.

The Efficacy of English Lavender

Among the various species of lavender, English Lavender, known scientifically as Lavandula angustifolia, is particularly successful in repelling flies. Its high concentration of essential oils makes it an excellent choice for this purpose.

Using Lavender as a Fly Repellent

There are several ways to use lavender to keep flies at bay.

Placing fresh lavender bouquets in your home not only provides a delightful scent for you but it also deters flies. As the blooms dry out, they continue to emit the fly-repelling aroma.

Lavender plants placed near windows, doors, or other entry points effectively discourage flies from entering your home. As a bonus, they add a splash of color and charm to your garden or patio.

Lavender essential oil also makes a potent fly repellent. A few drops on a cotton ball placed in fly-infested areas can be surprisingly effective. Alternatively, a mixture of water and lavender essential oil can be spritzed around your home to deter flies.

#4 Peppermint

Peppermint is a familiar herb renowned for its invigorating scent and culinary uses. Its bright, crisp aroma refreshes the senses and enhances dishes. An unexpected benefit of this aromatic herb, however, is its ability to repel flies.

Why Flies Hate Peppermint

Flies find the strong, fresh aroma of peppermint overwhelming. This potent smell affects the flies’ sensory mechanisms, leading to a strong aversion. While we appreciate the cool, revitalizing scent of peppermint, flies hate the smell.

#6 Clove

Clove is a well-regarded spice with a rich history of use in culinary and medicinal practices. It is revered for its warm, sweet, and slightly bitter flavor and its potent aroma. What many don’t know is that this fragrance also makes clove an effective fly-repellent.

#9 Bay Leaves

Bay leaves, familiar to many as a culinary herb, have a lesser-known use. Their strong, distinctive scent can repel flies, making them a useful tool for natural pest control.

Why Flies Hate Bay Leaves

Flies don’t enjoy the robust aroma of bay leaves. Compounds in the leaves, such as eugenol and cineol, interact with flies’ sensory perception. This interaction repels flies, creating an environment they prefer to avoid.

Bay Leaves: A Potent Repellent

With their intense fragrance, bay leaves offer potent fly-repelling properties. Their scent is much stronger than that of many other herbs, giving them an edge in driving flies away.

Using Vinegar as a Fly Repellent

There are various ways to utilize vinegar in your fight against flies.

One common method involves creating a homemade vinegar fly trap. Fill a jar halfway with vinegar, add a drop of dish soap (which breaks the surface tension), and cover the jar with plastic wrap. Poking holes in the plastic wrap allows flies to enter but not exit, trapping them.

Using a mixture of water and vinegar as a spray around windows and doors can also deter flies since they hate the smell and will generally stay away from sprayed areas.

Finally, simply leaving out a bowl of vinegar can act as a repellent due to its strong aroma.

Cedarwood, a durable and fragrant type of wood, serves more than just construction and decor. Its rich, earthy scent also acts as a natural fly repellent, making it useful in pest control.
