Temprid FX Insecticide is not labeled for household plants for soil application. Fungus gnats will commonly breed in the soil of house plants that may have too much moisture. You should read our Getting Rid of Gnats article that explains how to treat fungus gnats. We recommend using Talstar P which can be sprayed directly on the soil to help control fungus gnats and we also recommend letting the soil dry out completely between waterings.
