worth $5.20 per calf.
The cost of fly control is estimated at 51 cents per head.
An even larger return is likely, considering the link between face flies and the incidence of pinkeye. In University of Kentucky experiments, calves that had pinkeye at least once averaged 36 to 40 pounds lighter at weaning than calves not infected by the disease.
Cattle used about onetenth ounce of insecticide dust per animal per day. The normal fly season extends from May through September, or 153 days.
To install a fly control program in a 100-head herd, a producer will need to buy two dust bag kits costing about $18 apiece. Each kit comes with 25 pounds of insecticide dust. That plus two 25-pound refills, which cost about $7.50 each, should last the entire fly season, Roberts said.
To be effective, the dust bags must be installed where cattle are forced to come into contact with them every day. Fencing off the water supply works best, said Roberts.
