Lindell, regional extension specialist, during 1994-95, when field trials with two horn fly traps during the latter season averaged 40 percent control. Rather than emerging as adults, they overwinter (diapause). Wear and tear was low in field tests so a trap should last for several seasons. 2014; 97(7):4624-31 (ISSN: 1525-3198) Denning SS; Washburn SP; Watson DW Horn flies congregate on the backs of cattle, often clustering on the midline and spreading down the sides.
