What Plants Repel Fruit Flies

Flies 5

Fruit flies can be a real nuisance, especially during the warmer months when they’re most active. These tiny pests are attracted to ripe, rotting, or decayed fruit and vegetables, but they also breed in drains, garbage disposals, empty bottles, and cans. They lay their eggs near the surface of fermenting foods or other moist, organic materials. Upon discovering a fruit fly infestation, you might be tempted to use chemical insecticides to get rid of them. But there are more natural, safe methods to keep fruit flies at bay. One of these methods is to use plants that repel fruit flies.


Several plants are known to repel fruit flies due to their strong scents or chemical compounds. These include basil, lavender, peppermint, eucalyptus, rosemary, lemongrass, and the clove tree. These plants can be placed in key areas around your home to deter fruit flies. However, their effectiveness may vary, and it’s recommended to use them in combination with other control methods.

How Do These Plants Repel Fruit Flies?

Where to Place These Plants?

To maximize the effectiveness of plants in repelling fruit flies, place them in key areas around your home. Some strategic locations include near entry points, windowsills, tabletop trash bins, and around the kitchen where fruit flies are most likely to be attracted to ripe fruits and vegetables.

Caring for These Plants

To maintain the properties of plants that repel fruit flies, it is essential to provide proper care for each specific plant. Some general care tips include providing appropriate soil, watering regularly but not overwatering, placing the plant in a location with suitable sunlight, and pruning regularly to maintain its shape and promote new growth.

Drawbacks and Limitations
