Orthene PCO is one of the most popular and effective ways to control a wide variety of bothersome home and pantry pests, including ants, firebrats, crickets, pillbugs, earwigs, and cockroaches. Orthene PCO was uniquely designed to target and exert control over even the most stubborn household pests that tend to be resistant to other products, like the German Cockroach (which ranks among the most pesticide-resistant pest next to the housefly). Research continues to demonstrate that the active ingredient in Orthene PCO—acephate—remains one of few insecticides to which the German cockroach and other insecticide-resistant pests remain vulnerable. The unique 97 percent formulation of Orthene PCO Pellets means that you deal with less residue dust and lower odor. This product comes in the form of small pellets which dissolve easily water for use as a crack and crevice spray or for perimeter and spot treatments. Orthene PCO can be used on a variety of surfaces with stain or film, including stainless steel, tile, glass and porcelain. This product should not be used on carpet or upholstery.

Box contains 10 - 1.40 ounce packets

Directions For Use:

Cockroaches, Ants, Crickets and Firebrats: Apply as a coarse, low pressure spot spray, crack and crevice spray or with a paint brush to localized areas where these pests are found or normally occur. Including corners of rooms and closets, around television sets and radios, along and behind baseboards, around and under sinks, dishwashers, washing machines, refrigerators, stoves and cabinets; areas where plumbing enters or leaves the room or other areas inhabited by these pests. Note: A period of 3 to 7 days may be necessary for Orthene PCO Pellets to reach its maximum effect on cockroaches.

Earwigs, Pillbugs and Sowbugs: Apply as a coarse, low pressure spot spray to areas around doors and windows, storage areas, baseboards and other areas where these pests may enter or be found.

Pantry Pests - Exposed Stages (Confused Flour Beetle, Indian Meal Moth and Trogoderma): Apply Orthene PCO Pellets at 1.0% as a spot application to pantry and cupboard shelves where food containers suspected of being infested are stored. Prior to spraying, remove all foodstuffs, shelving paper and utensils. Do not replace the food packages until the surface has dried. Replace shelving paper. Infested food packages should be destroyed.

Wasps: Apply Orthene PCO Pellets as a spot application at 0.5% to 1.0% to the nest, nest entrance, and surrounding areas where the wasps alight. Wasps are generally less active early and late in the day, so it is advisable that nests should be treated during these times.

Perimeter Treatment: To control Cockroaches, Ants (including Imported Fire Ants), Pillbugs and Earwigs apply Orthene PCO Pellets at 0.5% to 1.0% to a band of soil 6 to 10 feet adjacent to the structure; also to a height of 2 to 3 feet on the foundation where pests may be active or may find entrance. Also, apply as a residual spray or with a paint brush to surfaces of buildings, window frames, shutters, entry ways, screens, eaves, patios, garages, carports, around garbage areas and other areas where these pests congregate. Note: When making perimeter treatments only foraging ants will be controlled.

Ants (including Imported Fire Ants) in Mounds within a treated perimeter or other non-crop areas: In order to control a mound or nest, a drench treatment is necessary. For mound drench treatment, dissolve on packet of Orthene PCO Pellets in 9 gallons of water. Apply on gallon of mix to each mound by sprinkling mound until it is wet and treat a four foot diameter circle around the mound. For best results, apply Orthene PCO Pellets in the early morning or late afternoon when ants are most active. Mound drench applications made under prolonged hot and dry conditions may be ineffective due to the location of ants deep within the nest. Note: Grass in treated areas may be injured. Do not treat a mound more than once per season.

For Application as Spot Treatment: Spot treatments may be applied at moderate pressure (up to 35 psi) using a coarse fan tip. For spot treatments, no individual spot will exceed two square feet. Mix Orthene PCO Pellets according to dilution chart. Apply as a spot treatment using coarse fan spray to areas inhabited by cockroaches. Treat areas such as baseboards, under and behind refrigerators, stoves, dishwashing and other equipment as well as in storage areas, closets, sinks, cabinets, around windows, doors and water pipes. Spot treatment should also include underside of drawers, shelves and other sites where cockroaches frequent or travel.
