ICON CS® is a modern micro-encapsulated insecticide containing lambda-cyhalothrin, a highly effective pyrethroid, approved by the WHO Pesticides Evaluation Scheme for indoor residual spraying in malaria prevention and control. It provides extended residual activity of up to nine months, outperforming conventional formulations, especially on porous surfaces like cement and mud and on difficult vinyl-painted surfaces. The polymer microcapsule protects the active ingredient after spraying, delivering fast knockdown and long-lasting control of a wide range of crawling and flying insects with minimal odour and no staining, ensuring high household acceptance. Supplied as a single-dose sachet for accurate, low-waste mixing, ICON CS® is easy to apply using standard compression sprayers and is suitable for indoor and outdoor use across domestic, commercial, industrial, and animal housing settings, targeting common insect resting and hiding areas.
