    Combine 15 drops of eucalyptus oil with ½ tsp of vodka and 2 cups of water in a spray bottle. Spray around the room and on furniture. Add more oil to make the scent stronger.

  2. 2

    Boil 2 cups of water. Place a bowl in the room you want air-freshened and add the boiled water. Deposit 10 or more drops of eucalyptus oil into the hot water. The steam heats the oil, creating rapid evaporation throughout the room. This method is effective, but lasts only a few minutes.
