Face flies are often found in large numbers in the presence of cattle, especially on warm days. Estimates of the number of face flies are based on flies counted on the faces of cattle and are subject to a lot of variation, therefore, better sampling techniques are necessary. The distribution of the face fly in South Dakota was determined by facial counts of flies from a vehicle using binoculars, during early morning hours along highway transits in eastern and western South Dakota from June through August. Both chemical and non-chemical methods of managing this pest are discussed, as well as biological controls, sanitation methods, and traps.
