Incorporating them into your outdoor spaces can significantly reduce the presence of these insects, contributing to a more enjoyable and peaceful environment. 

So, are you looking for plants that repel flies? You’re in the right place because in this post I’ll review 20 plants that repel flies. Let’s continue reading!

What Plants Keep Flies Away the Best?

Flies detest the strong, aromatic scents of certain flowering plants and herbs. This natural defense mechanism is particularly potent in sage and rosemary, which release a pungent aroma that’s delightful to humans but a deterrent to fly species. Additionally, the essential oils found in some aromatic herbs can be especially effective at keeping pesky flies at bay.

Furthermore, potted plants that thrive both indoors and outdoors create a barrier that species of flies are inclined to avoid. Their natural scents, which we might find pleasantly herbaceous or citrusy, act as a repellent, making these plants not just decorative but also functional in maintaining a fly-free zone.

Importance of Repelling Flies

Repelling flies is crucial for several reasons:

• Flies are carriers of bacteria and diseases, which can harm humans and livestock.
• The presence of flies can lead to food contamination and spoilage.
• Flies can be a nuisance, causing discomfort and annoyance in indoor and outdoor settings.
• Reducing fly populations can minimize the need for chemical insect repellents, which can harm the environment and other non-target species.

By employing flowering plants, sage and rosemary, and other aromatic herbs in our fight against flies, we utilize nature’s own tools without giving it a cold shoulder through chemicals like methyl acetate, often found in commercial insecticides.

20 Plants That Repel Flies

Imagine a garden bustling with activity, where flowering plants not only attract pollinators but also serve as natural insect repellents. Among these, plants that repel fruit flies and other insects like flies can be interspersed within garden beds, near a compost heap, or along the edges to create a protective barrier. These plants, with their ability to ward off unwanted insects, play a dual role in the ecosystem of your garden.

Moreover, the inclusion of perennial herbs and plants in your garden not only enhances its aesthetic appeal but also contributes to the biological control of flying insects. By cultivating a diverse range of these plants, you ensure the presence of flies is kept in check while still inviting beneficial insects that help pollinate flowers and support a healthy garden environment.

Basil

Basil, with its lush green leaves and distinctive aroma, is a formidable foe against outdoor pests.

As a bonus, lemon balm’s refreshing fragrance can enhance the sensory pleasure of spending time in your garden, all while keeping the airspace clear of flying annoyances. 

Carnivorous Plant

Carnivorous plants are not just fascinating specimens for botany enthusiasts; they are also natural allies in getting rid of flies.

Once trapped, the tiny hairs within these plants ensure that their prey cannot escape.

These living fly traps provide a dual service: they enhance the biodiversity of your garden and actively reduce the number of tiny insects.

Whether you’re grilling in the backyard or enjoying a quiet evening on the patio, rosemary can serve as a natural barrier against insects while also providing fresh herbs for your culinary creations. 

Marigold

Marigolds are not only known for their bright, cheerful flowers that thrive in warm weather but also for their insect-repelling capabilities.

Planting marigolds among vegetables and flowers can protect your plants from a variety of garden pests while adding a pop of color to your outdoor space. 

Sage

Sage, a revered kitchen herb, is also one of the notable plants that repel flies. Its pungent aroma acts as a natural barrier against garden pests. When dried and burned, the smoke from sage can enhance the ambiance around a fire pit and keep the flying insects at a distance.

Sage is easy to cultivate and requires minimal maintenance, so it is a robust addition to any garden. Its presence not only contributes to the culinary herbs at your disposal but also plays a significant role in maintaining a pest-free environment.

Carnivorous Plants

Carnivorous plants serve as both intriguing plants to grow and effective biological controls for flying pests. The alluring appearance of pitcher plants, Venus flytraps, and cobra lilies, complemented by their ability to trap insects, makes them a unique addition to any garden. Their tiny hairs and intricate trapping mechanisms ensure that once an insect is lured in by the sweet nectar, escape is nearly impossible.

By including carnivorous plants in your garden, you not only get rid of flies but also contribute to the natural oils and scents that deter flies. As fly-repellent plants, they offer a sustainable and fascinating method of managing unwanted insects without resorting to chemical solutions.

Lemongrass

Lemongrass is a tropical plant that’s as lovely to look at as it is effective in repelling insects, thanks to its high citronella oil content.

The laurel plant, especially the bay laurel, is a wonderful addition to any garden, and not just for its culinary uses. The aromatic leaves are excellent for keeping flies at bay, thanks to their intense fragrance, which flies find off-putting.

Eucalyptus

Eucalyptus is celebrated for its health benefits, particularly when it comes to its essential oils. But it’s also a powerful plant for repelling flies and other pests. The strong, minty aroma of eucalyptus leaves is uninviting to flies, who prefer not to linger around the pungent scent.

Planting eucalyptus in your garden not only provides a source of natural insect repellent but also contributes to a healthier garden environment. The distinctive smell acts as a barrier, deterring various pests and keeping your plants safe from their attention.

Wormwood

Wormwood carries a reputation as a natural insecticide, particularly effective against flies and mosquitoes. Its bitter scent and taste make it an unwelcome presence for these pests, who tend to avoid areas where wormwood grows.

The silver-green foliage of wormwood is not only practical for pest control but also adds a unique texture to garden beds. Incorporating wormwood into your landscape can provide both aesthetic appeal and a natural way to maintain a fly-free zone.

Venus Flytrap

Carnivorous plants like the Venus Flytrap are nature’s own pest control agents. They lure in flies and other small insects with their nectar and then trap them in their jaw-like leaves. While they may not repel flies in the traditional sense, they do help reduce the population of these pests.

Adding a Venus Flytrap to your collection can be both fascinating and functional. Although they require specific care to thrive, they can serve as a natural and engaging way to manage flies in your home or garden.

Tansy

Tansy is an herb with a history of use for its insect-repelling properties. Its fern-like foliage and bright yellow, button-like flowers can be an attractive addition to gardens. But more importantly, they release a scent that is very effective at keeping flies and other bugs away.

Plant tansy along the borders of your garden or near areas where you spend time outdoors to enjoy its protective benefits.

Nasturtiums

Nasturtiums serve as an excellent companion plant in the garden. Their vibrant blooms not only add a pop of color but also help repel pests like squash bugs. These colorful flowers release a scent that is unappealing to many insects, making them a natural and attractive form of pest control.

By interplanting nasturtiums with vegetables and other garden plants, you take advantage of their protective properties. Their presence can reduce the likelihood of pest infestations, keeping your other plants healthy and thriving.

Petunias are a delightful addition to any garden with their wide range of colors and patterns. But they are more than just pretty faces; petunias have a subtle scent that can help deter flies and other insects from taking up residence in your garden.

These annuals are easy to grow and maintain, making them ideal for both beginner and experienced gardeners. Planting petunias in hanging baskets or containers near your outdoor living spaces can not only enhance the ambiance but also contribute to a fly-free environment.
