Actellic CS (Syngenta), is a microcapsule formulation of the organophosphate insecticide, pirimiphos-methyl. Microencapsulation greatly extends the compound's residual life when applied to interior walls and ceilings. Evaluation by LSHTM in experimental huts in Tanzania showed residual activity of more than a year. Parallel trials in Benin against pyrethroid-resistant mosquitoes killed more than 80% of An. gambiae for up to 10 months.
