The product combines the proven efficacy of deltamethrin with Envu's proprietary FFAST™ (Film Forming Aqueous Spray Technology), allowing dilution with water while maintaining effective droplet suspension and mosquito control performance. qua K-Othrine® EW reduces the need for hydrocarbon diluents, helping lower environmental impact, operational costs and handling concerns while providing rapid knockdown of adult mosquitoes and flies.
