Mosquito Bits are an excellent way to rid yourself of fungus gnats. Scoop a tablespoon or two into your watering can and let sit for 1-2 hrs. Thoroughly water the infected plant, making sure the water soaks through all the soil. This will kill the larvae in the soil, preventing new gnats from hatching. We recommend pairing with our Gnat Stix, which will kill the live, adult gnats that are flying around.
