Lambda-Cyhalothrin 5% EW Public Health Insecticide for Mosquito & Cockroach Control

Lambda-Cyhalothrin 5% EW — Fast-Knockdown Oil-in-Water Emulsion for Public Health Pest Control

Ronch Lambda-Cyhalothrin 5% EW combines one of the most active pyrethroids available with an oil-in-water delivery system. The result is rapid knockdown and strong residual activity with far less solvent odor than a conventional EC, and no staining on painted or papered surfaces.

Key Benefits
• Fast knockdown at low dosage — quick visible effect after treatment
• Strong residual on walls, ceilings and screens
• EW formulation: low odor, good compatibility with paint, plaster and wallpaper
• Uniform emulsion — stable in the tank, no separation in the drum
• Effective against flying and crawling public health pests
• OEM / private label packing and registration documentation support

Target Pests
Mosquitoes, houseflies, cockroaches, bed bugs, ants.

Application
Shake well before use. Measure the required volume, add to half-filled water, mix and top up. Apply as a residual surface spray at 0.4–0.8 mL formulated product per m² (approx. 20–40 mg a.i.) to walls, ceilings, eaves, screens and hiding places. Re-treat when residual activity declines. Always follow the locally registered label.
