1. Make an apple cider vinegar trap

Place a few tablespoons of apple cider vinegar, a few drops of dish soap, and a tablespoon of sugar in a bowl and stir the contents. Set your bowl in an area where gnats are prevalent, like your kitchen or bathroom. The sugar and apple cider vinegar combination will attract gnats, and the dish soap traps the gnats and eventually causes them to drown.

2. Make a fruit trap

Homeowners can cover a jar of rotting fruit with perforated plastic wrap. The gnats will enter the jar and get stuck in it.

3. Pour diluted bleach down the sink or tub drain

If you notice gnats around your kitchen sink or bathtub, pour a cup of diluted bleach down the drains to kill the gnats.

4. Make a candle trap

Place a candle in a candlestick and fill the holder partially with water. Light the candle and turn off the lights. The gnats will flock to the flame and be burned or will fall into the water and drown.
