Altosid® IGR XRB is a long-acting horn fly control solution designed to
help manage horn fly populations in cattle herds. Administered as an
oral bolus, it delivers an insect growth regulator that works through
the animal to target horn fly development in manure. This approach helps
break the horn fly life cycle and supports more effective, season-long
fly management in grazing cattle.
