Gnatrol Organic B.T.I. Fungus Gnat Larvicide. OMRI Organic

• Application Instructions:

  *To be 100% effective 3 applications need to be made over 15 days.

  Apply once every 5 days to break the life cycle. 

  Application:
  
  1 teaspoon per gallon for an active light infestation.
  2 teaspoons per gallon for a medium infestation.
  3 teaspoons per gallon for a typical infestation.
  
  Apply it to the top 2 inches of soil as a drench every 5 days until the adults are not flying around anymore. Usually 15-20 days or less to fully eradicate them.

  Hydroponic application is the same mixture per gallon as soil but with a large reservoir it's easier to use weight per gallon over teaspoons:

  preventative use: 23- 46 grams per 25 gallons

  Light infestation: 1-1.5 ounces per 25 gallons

  Medium infestation: 2-3 ounces per 25 gallons

  Heavy infestation: 3.25 - 6.5 ounces per 25 gallon

• *As in soil you need to add B.T.I. to your hydroponic tank three times total, once every 5 days to break their life cycle.
