Robert W. Every, OSC Extenison Entomology Specialist is shown operating sprayer on sheep for ticks on a south Benton County farm. The nozzles were held close to the fleece in order to get skin deep penetration with the DDT solution. The sheep are loosely confined in a holding pen to facilitate spary coverage.
