You Will Need

  • Liquid soap
  • Plastic spray bottle
  • Cider vinegar
  • Cup or bowl
  • Cigarettes
  • Sticky trap
  • Gnat fogger
  • Citronella candles
  • Vodka or rubbing alcohol (optional)


  1. Step 1

    Water and spray with soap mixture

    If you have an infested plant, water it with a mixture of 2 tablespoons liquid soap per gallon of water, thoroughly drenching the soil. Then spray the leaves with the mixture.

  2. Try a mixture of ½ cup vodka and 1½ cups water or 1 cup rubbing alcohol and 1 quart water. Test a small leaf to make sure that the mixture is not harmful to the plant.

  3. Step 2

    Make a gnat trap

    Put 2 tablespoons of cider vinegar in a small cup or bowl, filling the rest with water. Place it near a gnat-infested area. The gnats will be attracted to the scent and will drown.

  4. You can place additional traps throughout your home.

  5. Step 3

    Scatter tobacco

    Scatter tobacco around the area. The nicotine in the tobacco will kill the gnats.

  6. Tobacco should not be used on food, herbs, or plants that produce food and should be used with caution if you have pets or children.

  7. Step 4

    Insert sticky trap

    Insert a yellow sticky trap into the soil of an infested plant or near an infested area. Gnats will be attracted to the color and will get stuck on the trap.

  8. Step 5

    Use a gnat fogger

    Use a gnat fogger to eliminate gnats in an outdoor area.

  9. Step 6

    Light citronella candles

    Light citronella candles to keep gnats away from outdoor areas.
