Small Scale Community Household Evaluation has been conducted in Zambia to evaluate VECTRON™ T500 residual efficacy applied on both concrete, mud and brick Community Household against pyrethroid susceptible Anopheles gambiae s.s. and resistant wild An. funestus s.l. It provided residual efficacy above 80% at the 120-hour mark during each monthly observation throughout the 12-month duration.
