University trials have proved Gnat Nix! used as a top dressing is an effective physical barrier against fungus gnats. Unlike other top dresses that are limited to one phase of control, Gnat Nix! controls gnats at different points of their lifecycle. It prevents adult emergence from hatching larvae and deters females from laying eggs in the growing media. As a result, the lifecycle of fungus gnats is interrupted, and its population significantly reduced.
