Fly Control — Viafield offers RangeLand® tubs and Wind and Rain® minerals with Altosid® insect growth regulator to prevent fly development. The adult horn fly is a biting insect that takes 20 to 30 blood meals a day, often found on the backs of cattle and clustering on the animals' midlines and spreading down their sides. The resulting stress interrupts the grazing patterns of cattle, causing them to go off feed. According to university research, calves from badly infested herds gain weight more slowly than normal calves and are lighter at weaning by 10 to 25 pounds. Begin feeding Altosid 30 days before fly emergence and continue feeding until 30 days after the first frost.
