Bradley from Atlanta, Ga writes
Bifen Granules need to be watered-in to activate them, while Niban Granular Bait - 4 lb. Shaker needs to be applied dry, so we would not recommend mixing these products since the water from the Bifen application would reduce the efficacy of the Niban. Also, Bifen can have some repellent tendencies, so it would be best to apply in separate areas.
