Gnatrol WDG (Water Dispersible Granule) biological larvicide offers the same effective control of fungus gnat larvae that growers expect from Gnatrol, but with added product benefits.For a few plants where I thought there were no fungus gnats, a few gnats flew out when I watered them. These pests thrive on both new and existing plant roots and cause widespread damage in a short time.

Since I did this about two weeks ago, the number of gnats definitely appear to have lessened both at home and in the office.t. to species of several invertebrate taxa (Acarina, Nematoda, Collembola, Annelida, Hymenoptera) inhabiting the soil has been demonstrated, but only rarely is it possible to relate dosage information to field situations, and in many cases the B.
