Orthene PCO Pellets

ORTHENE contains acephate, a proven compound with no known resistance. Pellets mix easily with water and can be used as a crack and crevice spray or for perimeter and spot treatments. Acephate offers the most effective German-cockroach control in today’s commercial kitchens. Because of acephate’s residual persistence, on tile, stainless steel and other smooth surfaces, ORTHENE is a preferred pest-control option of many food-service professionals.
