Cinnamon anyone? Fungus gnats. We've noticed a bit of an uptick in our fungus gnats lately - I've been trying to let our soil dry out a bit more while we focus on moving, in hopes we can purge the little buggers prior to the move but I'm looking for some extra ammo. I've heard cinnamon is good, but is that okay for all soil plants? Do I sprinkle it before or after watering? Should I put out some essential oils? Any help is appreciated, thank you!!!
