Flies are annual summer pests of cattle and other livestock. Controlling them could mean happier, healthier and heavier livestock, according to Lee Townsend, Extension Entomologist with the University of Kentucky College of Agriculture.
Horn flies are small flies that feed off the blood of cattle and in rare cases, horses. Young animals are the most susceptible to horn flies, as large numbers of flies feeding on an animal can cause lower weights.
