If there’s one thing that can ruin a perfect summer day or a dinner party, it’s the constant buzzing and landing of flies. These pesky insects seem to have a knack for turning up when they’re least wanted. But did you know that there are natural ways to keep them at bay? Various herbs, due to their strong aroma and natural oils, act as excellent fly repellents. In this comprehensive guide, we’re going to delve into the world of herbs that flies hate.
Flies are naturally repelled by several herbs due to their strong aroma and essential oils. Some of the most effective herbs that flies hate include basil, lavender, rosemary, mint, bay leaf, sweet woodruff, tansy, lemon balm, and catnip. These herbs can be planted in areas where you spend time to deter flies.
The Science Behind It
Flies are repelled by certain herbs due to the presence of essential oils and other compounds that are released when the foliage is bruised or moved. These essential oils are unpleasant to flies and deter them from approaching the plants. Some of the herbs that repel flies include basil, lavender, rosemary, and mint.
For example, peppermint oil has been found to be particularly effective in repelling Drosophila suzukii flies, preventing almost all flies from contacting treated wicks and remaining 100% repellent for 6 days post-application, as per a study. Thyme oil is unique because it causes high male mortality and reduces the number of flies that choose to approach it. Lemongrass oil (Cymbopogon citratus) is also an effective repellent against mosquitoes and house flies. Citronella, a constituent of lemongrass, has been reported to be as effective as N,N-diethyl-meta-toluamide (DEET) in repelling stable flies.
