📋 Key Facts at a Glance
🎯 Primary Uses in Pest Control
Lambda-cyhalothrin is used for: perimeter treatments around structures, lawn and garden pest control, indoor spot treatments, mosquito control in vegetation, and flea/tick treatments in yards. It's available in microencapsulated formulations (Demand CS) that provide extended residual through controlled release.
🛡️ Safety Summary
Lambda-cyhalothrin has low mammalian toxicity at typical use rates. It can cause mild skin tingling or paresthesia on direct contact — this is a transient effect, not a sign of toxicity. Eye irritant. Keep pets and children off treated areas until dry. Cats are sensitive to all pyrethroids — allow surfaces to dry completely before cat access.
🔬 Resistance Status
Significant resistance documented in German cockroach populations and bed bugs. For these pests, use indoxacarb-based gel baits (cockroaches) or chlorfenapyr/silica gel (bed bugs) instead. Lambda-cyhalothrin remains highly effective for ants, spiders, mosquitoes, and most other target pests.
