While best known for their roles in cooking, onions and cloves have long been used as a natural, chemical-free insect repellent. Across cultures, this duo has been relied on to keep flies, mosquitoes, and other pests at bay. Onions contain sulfur compounds and essential oils that emit a strong scent insects dislike.
Cloves add to the effect with eugenol, a powerful compound known for repelling bugs. To use, simply cut an onion and insert whole cloves into the cut surface. Place around your home—especially near windows or doors—to deter flying insects.
This method is not only eco-friendly and affordable but also safe for children and pets. As a bonus, it can help freshen the air, too.
