📋 Key Facts at a Glance
🎯 Primary Uses in Pest Control
Deltamethrin liquid (Suspend SC) is used for perimeter treatments, indoor crack and crevice, and surface sprays. Delta Dust is used primarily for: wall void treatments (via drill holes or outlet plates), attic treatments for overwintering insects, crawl space treatments, and harborage areas where liquid application is impractical. Delta Dust is particularly valued for treating wall voids that harbored yellow jackets, stink bugs, or roaches.
🛡️ Safety Summary
Very low mammalian toxicity at application rates. Skin tingling (paresthesia) on contact — transient, not a sign of systemic toxicity. Wear gloves and avoid inhaling dust during application. Respiratory protection (N95) recommended when dusting in enclosed spaces. Toxic to cats — ensure dry before cat access.
🔬 Resistance Status
Resistance documented in German cockroaches and bed bugs — similar profile to other pyrethroids. Delta Dust is still highly effective for ants, yellow jackets, cluster flies, stink bugs, and most other target pests in wall voids.
