Flies are a frequent presence in kitchens during the warmer months, attracted by ripe fruit, food scraps, and improperly stored trash. According to the Brazilian newspaper O Globo, a very common plant — basil — can work as a natural repellent for flies and other flying insects. The explanation lies in the essential oils present in the leaves, rich in volatile compounds that interfere with insects' sensory systems, making it harder for them to locate food and breeding grounds.
The characteristic smell of basil, valued in gastronomy, produces the opposite effect on many insects. A simple pot placed near a window, on a balcony, or on the kitchen counter can help reduce the presence of these insects. To enhance the repellent effect, you can lightly rub the leaves before placing them near doors or windows, or prepare an infusion with the leaves that, after cooling, can be applied to strategic areas through a spray bottle.
In addition to its repellent properties, basil contains antioxidant compounds, such as flavonoids and tannins, and ursolic acid, which has been studied for its anti-inflammatory properties. The plant is also associated with digestive well-being and potential relaxing effects, being used in infusions and aromatic preparations in different parts of the world.
Among the natural alternatives mentioned are apple cider vinegar diluted in water and the use of old CDs on windows, whose reflections create visual effects that can disorient flies. However, hygiene remains a fundamental factor: exposed food scraps, accumulated trash, and poorly cleaned surfaces create favorable conditions for the presence of insects. Properly storing food, regularly cleaning the kitchen, and installing mosquito nets are measures that complement the use of aromatic plants like basil.
