Gnatrol Fungus Gnat Control

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. The active ingredient is Bacillus thuringiensis israelensis (Bti). Once the larvae have ingested the insecticide, protein subunits paralyze the fungus gnat larvae, which stop feeding immediately and die - usually within 24 hours. Will not harm people, pets or the environment. Mix 1-2 tsp. / gallon of water. For heavy infestations use 4-8 tsp. / gallon of water.

As part of an Integrated Pest Management (IPM) program place Yellow Sticky Traps horizontally to control adult fungus gnats.
