Gnatrol Biological Larvicide. Fungus gnat larvae don't stand a chance. Gnatrol is a highly selective, biological larvicide for use in greenhouses to control fungus gnat larvae. It may be used on a wide variety of ornamentals, as well as all bulb crops, bedding plants and vegetable sets. Once the larvae have ingested Gnatrol, they become paralyzed, stop feeding immediately and die-usually within 24 hours. Gnatrol is now available in a water dispersible granule (WDG) formulation that will not leave a residue and is easier to measure for increased application accuracy. Gnatrol WDG is listed by the Organic Materials Review Institute (OMRI) for use in organic production
