Farnam SimpliFly with Larvastop Fly Growth Regulator 3.75LB

The Farnam SimpliFly with Larvastop Fly Growth Regulator is a highly palatable feed thru fly control for horses 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). This size contains a 60 day supply. 
SimpliFly has been proven to reduce fly populations by 97 to 100%.
