Gnat Nix is the only scientifically proven, environmentally friendly fungus gnat control product on the market. Trials at Kansas University have shown that used as a top dressing, Gnat Nix is an effective physical barrier against fungus gnats. Bottom line: Plants love it. Gnats don't.
How It Works: Gnat Nix! controls gnats at different points of their lifecycle, preventing adult emergence from hatching larvae and deterring females from laying eggs in the growing media. As a result, their lifecycle is interrupted, and its population is significantly reduced.
