Simplifly with Larvastop Feed-Thru Fly Control is a highly palatable feed additive to prevent the development of stable flies and houseflies in the manure of treated horses. Larvastop, containing fly growth regulator Dimilin, breaks the fly life cycle by preventing the formation of fly larvae's exoskeletons when they molt (resulting in their death).
