Introduction to The best fly repellent plants

Many of these bug-attracting beauties are suitable as herb gardens, long known for their medicinal and gastronomic qualities. Fortunately, they are also beautiful, smell soothing to us and, moreover, are pretty easy to grow if provided the right conditions.

They won’t just help prevent flies in the backyard; they will help keep flies out of the house, too. 

Best fly repellent plants

We’ve put together the eight best natural fly repellent plants so you can enjoy an uninterrupted and restful time outside;

1. Nasturtiums


Popular as an easy-to-grow house plant, nasturtiums will not only fill your backyard with beautiful edible flowers but also are plants that repel bugs. Because of the high concentration of naturally occurring limonene and myristicin in the leaves and flowers, flies simply can’t handle their sharp, slightly bitter scent and choose to stay far away.

2. Marigolds


Both French and American marigolds possess a solid spicy scent, and these red, yellow and orange flowers keep flies well away. 

3. Petunias 


These Bright and lush, overblown, sun-loving fly repellent plants can be seen growing in all types of containers at home. They possess insect-repelling chemicals too. Although there’s much dispute as to what exactly causes flies and other bugs to be at a distance from these fly repellent plants, it could be because of the hairy and sticky leaves and stems, which prove to be a deadly trap for most of the minor bugs. Petunias like to grow in moist but well-watered soil in a sunny spot.

4. Lavender 


Divine in both fragrance and looks, lavender is also brilliant at keeping flies and many other irritating insects at a distance. 

 Because of the high concentration of linalool in these fly repellent plants’ natural oil, it is simply too harsh for flies, bugs and mosquitoes to handle its fragrance. As a result, they stay pretty far.

5. Rosemary 


Despite being a habitant of warm, Mediterranean altitude, these distinctive domestic herbs are pretty tough and, because of their sweet woody scent, are outstanding fly repellent plants. It may lose leaves during the winter season unless sheltered, but these fly repellent plants should reshoot leaves in spring. Avoid getting the soil to become sodden.

6. Mint


Fabulous in food and drink, most of the gardeners adore growing mint. They are loved by humans but hated by flies and other bugs. Spearmint and Peppermint are two of the most potent scented mints worth growing plants that repel bugs.

7. Common Sage
