fungus gnat products
We apparently bought a bag full of fungus gnat potting soil, and since then, have had trouble with getting rid of the obnoxious gnats. We have tried diatomaceous earth, hydrogen peroxide, burying with small pebbles and even sand. Any better suggestions for a lasting eradication? Even the organic potting soil we’ve bought since has not helped (but that may be because the gnats weren’t fully eradicated before we planted more seedlings).
