As spring arrives in the UK, bringing warmer temperatures around 15°C, flies become increasingly active, often invading homes. Instead of resorting to chemical insect repellents, experts from Time For You, a professional cleaning company, suggest using natural methods to deter these pests. Placing orange or lemon peels near windows and bins can mask the scents that attract flies, making your home less appealing to them. Citrus fruits contain limonene, an oil that disrupts flies' navigation abilities, tricking them into believing there's no food nearby. Additionally, keeping herbs like basil, mint, and lavender on windowsills can further repel flies. For a homemade air freshener, boiling citrus peels and transferring the solution into a spray bottle can serve dual purposes as a pleasant scent and pest deterrent. By employing these natural strategies, you can enjoy fresh air without the annoyance of flies.
