A highly palatable feed additive to prevent the development of stable flies and houseflies in the manure of treated horses. LarvaStop, containing the fly growth regulator Dimili, breaks the fly life cycle by preventing the formation of fly larvae's exoskeletons when the molt (resulting in their death).
