Flies will turn around and buzz away if one item is put in garden

Natural Pest Control: Mint as an Effective Fly Deterrent

As warmer weather and sunshine return, many are noticing the unwelcome resurgence of flies. These buzzing insects, including bluebottles and fruit flies, are already becoming a nuisance this spring, with infestations expected to worsen as summer approaches. However, an effective natural method exists to prevent flies from entering your home: planting mint. This readily available and affordable herb, often priced between 60p and £1 in supermarkets, is simple to cultivate and maintain, offering a natural solution to repel these common household pests.

Using Mint to Repel Flies

Mint can be planted directly into the ground or placed in pots on windowsills, both indoors and outdoors. For optimal fly deterrence, position mint plants near potential entry points such as windows and doors. Flies possess an aversion to mint, as well as lavender and marigold, according to Little Bird Organics, who advocate for planting these herbs in gardens and placing pots inside homes to deter flies before they reach the entrance.

Alternative to Planting: Peppermint Oil Spray

For those who prefer not to plant mint, particularly due to its rapid spreading nature, a peppermint oil spray offers a convenient alternative. This method allows for easy reapplication to maintain its repellent effectiveness without the need to manage plants. Essential oil retailer Nikura notes that peppermint oil, like other insect repellents, deters flies due to their dislike of its scent. Spraying peppermint oil around the home can discourage flies, prompting them to seek alternative locations.

Scientific Evidence Supporting Peppermint Oil’s Effectiveness

Studies have demonstrated peppermint oil’s efficacy as a fly repellent. One experiment presented flies with a choice between a juice-baited candle and a candle wick with juice and peppermint oil. In every instance, the flies avoided the peppermint oil, opting for the juice-only wick. Further research indicated that peppermint oil significantly reduced lice infestations on buffalos within 3 to 9 days of application. While lice differ from flies, this finding illustrates peppermint oil’s broader insect-repelling capabilities, suggesting its deterrent properties are transferable and effective against various pests.
