A mint plant costing as little as £1.17 from Asda can effectively stop flies from entering your house during hot summer weather, according to gardening experts and pest control specialists. The plant, also available at Sainsbury's, Ocado, Tesco, and most garden centres for between £1 and £4, emits a pungent smell that flies, wasps, and other winged insects find repulsive.
How Mint Plants Work as a Natural Fly Repellent
Flies and other insects often swarm into homes when windows and doors are opened to let in fresh air during heatwaves. While many people resort to swatting or using chemical sprays, these methods can harm beneficial pollinators like bees and blow flies. Mint plants offer a humane alternative. According to Natran Green Pest Control, flies such as fruit flies and bluebottles are repelled by the scent of mint, as well as basil and citronella.
The pest control company states: "In addition to making your house smell minty fresh, herbs like spearmint and peppermint can also keep flies at bay. Mint grows quickly and makes an excellent addition to your backyard garden or your windowsill." For those who struggle to keep plants alive, spearmint or peppermint essential oils can also prevent fly infestations.
Practical Tips for Using Mint to Deter Flies
To maximise the repellent effect, place mint pots on windowsills, near doors, or on countertops. The scent will deter flies without harming them. For a stronger effect, diffuse peppermint oil indoors. Outdoors, plant mint along garden edges or in planters near dining areas. A DIY fly spray can be made by combining peppermint oil with water for use on kitchen counters or patio furniture.
Basil as an Alternative Fly Repellent
Basil works in a similar way to mint. Natran Green Pest Control explains: "Sweet basil is a delicious-smelling (and tasting) herb you can grow indoors or outdoors. Not only will it help you naturally keep flies away, but it also provides you with a never-ending supply of tasty garnishes!" Basil essential oil can be diffused, or fresh basil leaves blended with water and vinegar to create a natural cleaning spray that repels flies.
Cost-Effective and Eco-Friendly Solution
With prices starting at just £1.17, mint plants are an affordable and environmentally friendly solution to the common problem of flies entering homes in summer. Unlike chemical insecticides, they pose no risk to children, pets, or beneficial insects. By placing these plants strategically, households can enjoy open windows and doors without the nuisance of buzzing flies.
