Overview

Fungus gnats live and thrive in the soil of houseplants. If you have a fungus gnat infestation and do not want to use commercial insecticides or pest strips, you may already have the solution to your problem in your house. A little cider vinegar in a container may be all you need to get rid of your fungus gnat problem for good. If the gnats in your house are too smart for the simple vinegar solution, a slightly more involved remedy involves judicious application of peanut butter along with the vinegar.

Step 1

Pour a small amount of cider vinegar into your container. About 1 inch of liquid will suffice.

Step 2

Place the container of cider vinegar near the infested houseplant. Fungus gnats should dive into it, as they are attracted to the smell. They will then drown.

Step 3

Rub peanut butter on the inside of the lid to the bowl or container you are using for the cider vinegar.

Step 4

Poke holes in the lid of the container with a knife. Make sure the holes are not very large. Secure the lid on top of the container, with both the vinegar and the peanut butter inside.

Step 5

Strain the vinegar into a new container after you have attracted a bunch of fungus gnats with it. This will allow you to reuse it until your gnat problem is completely quashed.

Things You'll Need

  • Cider vinegar
  • Small lidded bowl or container
  • Peanut butter
  • Knife
  • Strainer (optional)
