LAVA-LITE NO-GNATS offers a simple, 100% natural solution to the eradication of fungus gnats on your houseplants and office plants. By creating a barrier between the soil and the air, NO-GNATS inhibits the ability to lay eggs in the soil and for the fungus gnat larvae to escape, stopping the fungus gnat life cycle. It also offers the added benefit of being a pH neutral product that can be used with any household plant variety and its composition increases moisture retention. Choosing NO-GNATS is a sound ecological decision, with no harmful chemicals or pesticides.
