Deltamethrin 2.5% WP Public Health Insecticide for Mosquito & Cockroach Control
- Introduction
Introduction
Deltamethrin 2.5% WP — Wettable Powder for Public Health Pest Control
Ronch Deltamethrin 2.5% WP is a free-flowing wettable powder that disperses quickly in water and stays suspended in the spray tank. It delivers fast knockdown plus long residual activity against mosquitoes, flies and cockroaches, and the powder form is ideal for crack-and-crevice work and dry surface treatment where a liquid carrier is not practical.
Key Benefits
• Fast knockdown and long residual on walls, ceilings and screens
• Excito-repellent effect — reduces mosquito entry and resting indoors
• Disperses easily; stable suspension with low foaming
• 1 kg foil bag: retail-ready, easy to divide and resell
• Long shelf life, no frost damage in storage or transport
• OEM / private label packing and registration documentation support
Target Pests
Mosquitoes, houseflies, cockroaches, bed bugs, fleas, ants.
Application
Add the required amount of powder to half-filled water while stirring, then top up. Apply as a residual surface spray at 0.8–1.0 g powder per m² (approx. 20–25 mg a.i.) to walls, ceilings, eaves and hiding places. For crack-and-crevice work apply dry where the label permits. Always follow the locally registered label.
