How to Make a Candle at Home with Coffee: Mosquito and Insect Hacks


Are you looking for a natural and effective way to keep mosquitoes and insects at bay? Making a candle at home with coffee is a fun and easy solution that not only repels bugs but also fills your space with a delightful aroma. Here’s how you can create your own coffee-infused candle.


To make a coffee candle, you’ll need:

  • Soy wax flakes or beeswax
  • A candle wick
  • A heatproof container (like a mason jar or a small glass)
  • Ground coffee (used or fresh)
  • Essential oils (optional, for added fragrance)
  • A double boiler or a makeshift one (a pot and a heatproof bowl)
  • A stirring stick or spoon

Preparation Steps

  1. Prepare the Container: Place the candle wick in the center of your heatproof container. You can use a bit of melted wax to stick it to the bottom, ensuring it stays in place.
  2. Melt the Wax: Fill a pot with water and place a heatproof bowl on top to create a double boiler. Add the wax flakes or beeswax to the bowl and heat gently until completely melted, stirring occasionally.
  3. Add Coffee Grounds: Once the wax is melted, add 2-3 tablespoons of ground coffee. If you’re using used coffee grounds, make sure they are dry to prevent any moisture from affecting the candle. Stir well to evenly distribute the coffee throughout the wax.
  4. Add Essential Oils: For an extra layer of fragrance and insect-repelling power, add a few drops of essential oils such as citronella, eucalyptus, or lavender. These scents are known to repel mosquitoes and insects.
  5. Pour the Wax: Carefully pour the melted wax mixture into the prepared container with the wick. Leave a bit of space at the top of the container. Adjust the wick if necessary to keep it centered.
  6. Cool and Set: Allow the candle to cool and set completely, which can take a few hours. Once the wax is solid, trim the wick to about 1/4 inch.

How It Works

Coffee Grounds: Coffee grounds release a pleasant aroma when heated, which is known to repel mosquitoes and insects. The combination of coffee and essential oils creates an effective barrier against pests.
