Onions and cloves, common kitchen staples, have long been used together as a natural remedy to help repel insects like flies and mosquitoes. This old-fashioned trick, popular in many cultures, offers a safe and chemical-free alternative to commercial bug sprays.
The secret lies in their strong natural compounds. When cut, onions release sulfur-based compounds that create a pungent aroma, while cloves contain eugenol — a natural substance known for its insect-repelling properties. Together, they produce a powerful scent that many insects find unpleasant.
