Flies can be a major nuisance during warm weather, especially when doors and windows are left open to cool down the home. According to a viral Instagram video from home renovations account The Hitchcock House, a simple kitchen hack can banish flies in just 15 minutes using coffee grounds.
The Coffee Grounds Hack
The trick involves placing coffee grounds—either fresh or leftover from a coffee machine—on a baking tray and heating them in the oven for 15 minutes. The strong aroma released is unpleasant to flies, causing them to flee the area. As an added bonus, the scent makes the home smell pleasant to humans.
The Hitchcock House shared: "How to remove the flies from your house this summer. Burn coffee in the oven for 15 mins (can be leftover coffee from your machine). Smells amazing, and the flies hate it."
Reaction and Effectiveness
Commenters on the video expressed enthusiasm for the hack, with many saying they planned to try it immediately. One person commented: "Definitely trying this today." Another added: "Well, I know what I'll be doing tomorrow." A third user noted: "In Kefalonia, they burn espresso pucks at restaurants to repel wasps and flies. And that smells wonderful too."
However, some commenters who dislike the smell of coffee said they would not try the method themselves.
Alternative Natural Remedies
For those who prefer other scents, several natural alternatives can deter flies. Herbs such as basil and mint are effective; placing potted basil or mint on a windowsill can help keep flies away while providing fresh herbs for cooking. In the garden, plants like lavender and marigold can deter flies and other insects when placed near windows and doors.
Cinnamon is another scent flies dislike. Placing cinnamon sticks near windows can repel flies and many other insects. Keeping the home clean and tidy also helps prevent fly infestations. Food should never be left uncovered on kitchen counters, and food waste bins should have tight seals. If a food waste bin is not available, biodegradable food waste bags can be used to seal scraps before disposing of them in household waste.
