Last week i had a major problem with Fungus Gnats, I didnt want to deal with them using chemicals , so i went to Lowes and bought a 50 pound bag of sand (sand for a sandbox) it was cheap only 4 bucks. I placed a 1 inch layer of sand on top of all my containers. Today is 9 days after, and i can say there is no trace of fungus gnats anywhere.
