ORTHENE® PCO Pellets with acephate effectively control cockroaches, ants, crickets, firebrats, wasps, earwigs, pillbugs and sowbugs. ORTHENE contains acephate, a proven active ingredient. 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 commercial kitchens. Because of acephate’s residual effectiveness on tile, stainless steel and other non-porous surfaces, ORTHENE is a preferred pest-control option of many food-service professionals.
