Brian from Kc, Mo writes
Bifen Granules should never be applied through any sprayer of any sort. This is a granule that should be applied with a spreader only and once applied to the yard watered in by sprinkler or irrigation or light rain to activate it. These are granules that are designed to break down slowly over time and last over a period of 2-3 months dependent on weather over that time frame. If you wish to spray an insecticde on your lawn you should use Bifen I/T which is a liquid concentrate product forumlated for that use.
