Ensure that the coffee grounds are dry. If you’re working with used grounds, spread them out on a baking sheet and allow them to dry completely. You can also place them in a warm oven for a few minutes to speed up the drying process.
Set Up Your Burning Area:
Place aluminum foil or a fireproof container on a heat-resistant surface. This can be an outdoor area like a patio or a well-ventilated indoor space near open windows to avoid smoke buildup.
Add the Coffee Grounds:
Put a moderate amount of coffee grounds in the center of the foil or container. You don’t need a lot; a couple of tablespoons will suffice for a small area.
Ignite the Coffee Grounds:
Use a match or lighter to ignite the coffee grounds. They may not catch fire quickly, but they should begin to smolder. If they go out, gently blow on the embers to revive them.
Monitor the Burning Process:
Allow the coffee grounds to smolder, periodically checking to ensure they are still burning. Add more grounds as necessary to keep the smoke flowing.
Prioritize Safety:
Never leave burning coffee grounds unattended. Keep children and pets away from the burning area to prevent accidents or ingestion.
Strategically Position the Coffee Grounds:
When using this method outdoors, position the burning coffee near seating areas or entry points to your home for maximum repellant effect. Indoors, place it near windows or doors where insects may enter.
