To create homemade bed bug repellent, make an infusion of mint and water. The supplies you need for this 15-minute project are distilled water, fresh mint leaves, a liquid measuring cup, a spray bottle, mild soap, a kitchen towel, a chef's knife, a cutting board, a funnel, a slotted spoon, a medium pot and a stove.

  1. Wash the bottle

    Take the top off of the spray bottle, and wash both parts in hot, soapy water. Set them on a clean kitchen towel.

  2. Heat the water

    Set a medium pot over high heat, and pour in four cups of distilled water.

  3. Prepare the mint leaves

    Rinse the mint leaves in cold tap water. Lay them on a cutting board, and chop them coarsely with a chef's knife.

  4. Drop the mint into the water

    Add the chopped mint to the water pot. Bring the mixture to a rolling boil, and then turn the heat down to medium. Simmer the infusion for 10 minutes.

  5. Strain the infusion

    Turn off the stove, and move the pot to a cool burner. Set the spray bottle next to the stove, and stick the funnel inside. To keep the mint leaves out of the bottle, place a large slotted spoon along the pot's bottom edge. Slowly pour the minted water through the spoon and into the funnel, and then discard the leaves.

  6. Cap the bottle

    Remove the funnel, and cap the bottle. Use the spray immediately, and store the leftovers in the refrigerator. Use them within one week.
