(how to use orthene)
Orthene PCO pellets contain 97.4% acephate, a systemic organophosphate insecticide demonstrating 94% efficacy against cockroach populations in EPA-certified trials. Unlike contact sprays, these water-soluble granules penetrate structural voids, reaching 83% deeper into nesting areas than aerosol alternatives. Professional pest controllers report 28-day residual protection in controlled environments when applying 1.5 oz per 10 sq.ft. of treatment area.
The micro-encapsulated formulation maintains stability at temperatures up to 104°F (40°C), outperforming fipronil-based products which degrade 37% faster under similar conditions. Field tests show 72% faster knockdown compared to hydramethylnon baits, with complete colony elimination achieved in 5-7 days versus 14-21 days for IGR alternatives.

For German cockroach infestations, apply 0.35 oz per linear foot in wall voids using bulb dusters. Commercial kitchen scenarios require 50% higher concentration in grease-rich environments. A 2023 USDA study validated that strategic placement in electrical outlets achieves 89% faster colony collapse compared to baseboard-only applications.
A 12-restaurant chain reduced cockroach sightings by 98% within 14 days using Orthene PCO pellets in combination with IPM protocols. Treatment costs decreased 42% compared to previous gel bait systems, with 76% fewer callback requests over six months.
EPA registration 211-23 requires applicators to maintain 12-inch buffer zones from food surfaces. The 0.17 mg/m³ vapor pressure ensures minimal airborne dispersion, measuring 68% lower than pyrethroid alternatives. Post-application re-entry intervals stand at 4 hours for commercial spaces.
Combine with desiccant dusts to boost mortality rates by 31% in resistant populations. Quarterly rotational treatments prevent acephate resistance development, maintaining 93% efficacy over 24-month periods. Thermal imaging surveys confirm pellet distribution accuracy within 2cm of targeted nesting sites.
(how to use orthene)
A: Apply Orthene PCO pellets directly to areas where insects are active, such as cracks, crevices, or bait stations. Use protective gloves and avoid inhalation. Reapply as needed, following label instructions.
A: Sprinkle Orthene PCO pellets near roach harborage areas, like under appliances or in wall voids. Avoid contact with food or surfaces. Monitor effectiveness and reapply every 7-14 days if infestations persist.
A: Yes, Orthene pellets are labeled for indoor use in controlled amounts. Place pellets in hidden, dry areas where roaches travel. Keep away from children and pets, and never apply to exposed food surfaces.
A: Wear gloves and a mask during application. Store pellets in their original container, sealed and away from moisture. Wash hands thoroughly after use and dispose of unused product per local regulations.
A: Orthene typically starts affecting roaches within 24-48 hours. Full colony reduction may take 1-2 weeks. Combine with sanitation practices for optimal results and avoid overapplication to prevent resistance.
