Keep Flies and Mosquitoes at Bay with Burning Coffee Grounds: A Natural Insect Repellent You Can Trust

When summer rolls around, so do the swarms of pesky flies and blood-thirsty mosquitoes. While there are plenty of commercial repellents available, many contain harsh chemicals that some people would rather avoid. Fortunately, there’s a simple, eco-friendly, and cost-effective solution hiding in your kitchen: burning coffee grounds.

Why Coffee Grounds?

Coffee isn’t just a morning lifesaver—it’s also a powerful natural deterrent for flying insects. Flies and mosquitoes are repelled by the strong, acrid smell produced when coffee grounds are burned. The smoke masks the carbon dioxide and body odors that attract these bugs in the first place, making it harder for them to find you.

What You’ll Need

  • Used coffee grounds (dried)
  • A heatproof container (like a metal bowl or ashtray)
  • A lighter or matches
  • Aluminum foil (optional)
  • Incense burner or outdoor-safe dish (optional)

How to Burn Coffee Grounds to Repel Insects

  1. Collect and Dry the Grounds: After brewing coffee, save the used grounds and spread them out on a tray to dry completely. Wet grounds won’t burn effectively.
  2. Prepare Your Burning Area: Place the dried grounds in a heatproof container. If you’re indoors, make sure the space is well-ventilated. If you’re outdoors, place the container where the smoke can circulate freely—like on a picnic table or patio corner.
  3. Ignite the Grounds: Light the coffee grounds with a lighter or match. They may smolder rather than burst into flame, which is ideal. The slow burn produces a steady stream of smoke.
  4. Keep It Going: To maintain the smoke, you may need to stir the grounds or add more dry coffee periodically. You can also mix in a bit of dry sage or bay leaves for an extra punch.

Bonus Tip: Add Essential Oils

For an even more potent effect, mix a few drops of insect-repelling essential oils—like citronella, eucalyptus, or peppermint—into the coffee grounds before burning. Just be cautious with indoor use, as some people and pets may be sensitive to strong scents.
