Orthene PCO insecticide stops ants, cockroaches and other pests before they get out of control. With its active ingredient acephate, Orthene PCO eradicates pest insects quickly and provides systemic control for two weeks. It knocks out cockroach infestations indoors, kills ant colonies in residential landscapes and eliminates pantry pests in food establishments. If pest insects have taken over your home or business property, Orthene PCO can get things under control.

How Orthene PCO Works

With 97.4 percent acephate, Orthene PCO targets and kills pest insects that have grown resistant to other pesticides. Once contacted or ingested, it coverts to methamidophos, a stronger insecticide and affects the insect's nervous system. The insect then experiences over-activity in its nerves and muscles and eventually dies. Acephate also penetrates leaf surfaces, providing quality control over many different leaf-damaging insects such as aphids and leaf miners. Orthene PCO comes in pellet form, dissolves easily in water and produces less residue dust than similar pesticides.
