When the larvae eat them, the alkaline nature of their digestive system causes these crystals to dissolve and be converted into toxic protein molecules that destroy the inside of the larvae's stomach. Without effective control, fungus gnat larvae can devastate commercial greenhouses and interiorscapes.

Gnatrol WDG Biological Larvicide provides fungus gnat control on indoor ornamentals and plantscapes.For a few plants where I thought there were no fungus gnats, a few gnats flew out when I watered them. I do first plan on adding another culture of springtails, give them a couple weeks to establish and see if that affects the gnats at all. Therefore, applications must be timed for a stage of development when larvae are present in the soil. While they do a great job of trapping adults they don't seem to be stopping new larvae (remember that it just take one gnat to get through the perimeter alive to lay 200-300 eggs). These are also common factors of wilted plants and may not necessarily indicate a larval infestation.
