Gnatrol WDG is a highly selective biological larvicide designed to control fungus gnat larvae in soil and growing media. Ideal for use in greenhouses, grow rooms, and indoor collections, this OMRI-listed formulation is safe for use on African violets, gesneriads, bulb crops, bedding plants, ornamentals, and vegetable starts.

Once ingested, Gnatrol’s active bacteria (Bacillus thuringiensis israelensis) quickly paralyze and kill larvae, usually within 24 hours. The water dispersible granule (WDG) formulation ensures easy measuring, no residue, and greater application accuracy — whether used as a soil drench or in hydroponic systems.
