Put Diatomaceous Earth around walls, windows, doors and around reservoir /// plant trays, and or on 1 clone collar (One above the other. Covering stops wetting...). Kills 100% with a fan on an Automatic Timer 15 minutes on / 15 minutes off. Kills hornets, mites, and gnats... I saw an ant do 6 push up's on diatomaceous earth! Bugs eat Diatomaceous Earth and die!
