I am having a wedding in September and looking for something to control sand gnats.
Bifen Granules would not be a good choice to treat for this pest. Talstar P will offer some control if applied to the trees, bushes and grass a few days before the wedding to lower the gnat population in the area. The morning of the wedding you may want to try to use a pyrethrin based product such as Riptide in a mist blower over the whole area which will kill anything that is flying around and help repel the gnats from the area for several hours.
