Demand the best and kill the mosquito callback with the Demand CS insecticide and Archer insect growth regulator (IGR) Multipak from Syngenta. As part of the SecureChoice Mosquito Assurance Program, this product combination can guarantee a significant reduction in mosquito populations for up to 60 days. The program also offers a proven 30-day assurance using only Demand CS. Powered with iCAP technology, Demand CS includes different-sized microcaps that provide a controlled release of the active ingredient, lambda-cyhalothrin — resulting in immediate and long-term control. Adding an IGR, like Archer, can further suppress mosquito populations by controlling larvae before they hatch into adults.
