How 221L Insecticide Works

221L insecticide residual aerosol contains the synthetic active ingredient pyrethroid called lambda-cyhalothrin. Like other pyrethroids, this active ingredient targets the central nervous system of pest insects. It causes hyperexcitation and prevents the pests from grooming, feeding and performing other functions. Before long, the pests become paralyzed and die. Unlike other pyrethroids, lambda-cyhalothrin provides a residual effect and continues to control the pests after the ingredient has dried on the surface.
