Otis from Thomson, Ga writes
Does it work to kill insects on top of the ground or can it be used to kill and maintain fire ant hills? The queen stays near bottom of the hill so it would need to be carried by the worker ant to the queen.
Bifen Granules are an insecticide granule that kills insects on contact: it is not a bait. Bifen Granules can be used as a drench on fire ant mounds. In this treatment, you are relying on the water to break down the granule and carry the active ingredient deeper into the soil. We outline both insecticide and bait treatments for fire ants in our Guide online here.
