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.

To make this simple repellent, cut an onion into halves or quarters and insert several cloves into the exposed surface. Place it near doors, windows, or spots where bugs tend to gather. While this won’t cover large areas or replace stronger repellents, it can help deter flying insects in small spaces.

An added bonus? This method is eco-friendly, inexpensive, and safe for homes with children and pets. Although the onion scent might not be what everyone calls “fresh,” it’s a natural way to keep bugs at bay without relying on harsh chemicals.
