How to Make a Gnat Trap

One way to get rid of gnats that are invading your houseplants is to create a gnat trap. This trap is also successful in killing fruit flies. Use a pint or quart sized mason jar and fill one half of the way with apple cider vinegar. Add a couple of drops of Dawn dish soap to the apple cider vinegar.

Place a piece of cheesecloth on top of the jar and secure with a rubber band. You can also use plastic wrap, and poke a few holes in the plastic wrap with a toothpick. The gnats will fly in through the holes and get stuck in the dish soap and drown. If you don't have a mason jar, you can also use a small glass bowl.

Place your gnat trap near your houseplants and replace occasionally with new vinegar and dish soap.
