8 oz. (1/2 lb.) repackaged Gnatrol WDG Biological Larvicide (by Valent).  OMRI Listed.  For use in organic production in soil and hydroponic applications.
We are repackaging the FRESHEST Gnatrol on eBay from Valent (manufacturer) Lot No. 311-809-PG30. We provide the lot number for your reference and for proof of date of manufacture (March 7, 2020).  Expires September 7, 2022 (this is 9 months longer than other listings).
Gnatrol is a larvicide — it will kill fungus gnat, shore fly, and mosquito larvae.
Application Directions:Light infestation:  3.2 – 6.4 oz. per 100 gallons applied as a soil drenchHeavy infestation:  13 – 26 oz. per 100 gallons applied as a soil drench
The fungus gnat lives and lays eggs for about 7 days.  I recommend making 3-4 applications spread out over 7-10 days.  This will kill the existing larvae upon first application and subsequent applications will kill larvae that hatches from eggs already laid and ones laid by the fungus gnats you see flying around.
As a courtesy, we provide tracking on all shipments.  Check your purchase status for tracking updates.
About Us:We are a mid-sized hydroponic farm in NE Florida.  We’ve been in operation for over 10 years and have lots of experience with about every problem (insects, fungus, bacteria, nutrient deficiencies, and hurricanes – not much help to you there!).  If you have any questions, feel free to contact us.  A lot of what we use we buy in pallet sized quantity – so check us out from time to time as we add more items that we think might be useful to the hydroponic grower.  If you don’t see something that you need, ask us!  We probably have it.
