It’s crucial you use enough stones to deter the bugs. The stones don’t stop water from getting to the roots of your plants when you give them a drink, but they keep gnats from getting in to lay eggs in the soil.

Cinnamon powder is a natural fungicide that has been shown to be particularly effective against damping off. It helps control fungus gnats by destroying the fungus that the larvae feed on. True Ceylon cinnamon, or Cinnamomum verum, will work best.
I’ve used a half-inch layer of sand for years using the same principle, and that’s been a cheap and fairly effective control. This winter, I tried a sample bag of Gnat Nix from Growstone and found it worked even better than sand. I’ve seen almost no fungus gnats all winter.
Use Sand or Gravel
Fungus gnats only lay their eggs in the top inch of soil. Replacing that top inch with sand or gravel creates a dry environment and robs them of nutrient-rich fungus to munch on. Without their needed source of food available, they won’t want to lay their eggs.
Fungus gnat larvae look like small white worms with a shiny black head. These larvae feed on fungus and need moist conditions to survive. This will not be a quick solution, but over time will reduce the number of flies seen as the larvae dry out and die.
Peppermint is a natural repellent that will keep gnats away from the home and garden. In a spray bottle, mix two cups of water with a spoonful of liquid dish soap and 20 drops of peppermint essential oil. Spray around the home, garden and lawn every few weeks or as needed to keep gnats at bay.
Lure and kill gnats with a mixture of apple cider vinegar, water, sugar, and dish soap. (Alternatively, achieve the same result simply by combining red wine and dish soap.) Pour diluted bleach down the sink or tub drain, if you find gnats hovering near plumbing fixtures.
Household Tips for Killing Gnats
That remedy involved putting out a plate of water with a little dish soap in it. Gnats, like Jesus, have the ability to walk on water. Unfortunately for gnats, they lose that super-power when you break the surface tension of the water with a few drops of dish soap.
The fungus gnat – a common indoor pest that thrives in the overwatered soil of potted plants or greenhouses – lives out its life cycle in three to four weeks at temperatures of 77 degrees Fahrenheit or higher.
If those pests just won’t quit, you can use a solution of water and soap in a spray bottle to spray into the top layer of soil (or pour it directly on top). You can also do this with an organic insecticidal soap or Neem oil mixture; these natural pesticides should be effective after a few treatments.
