For indoor residual spraying (IRS) of pirimiphos-methyl (PM), as well as window screens and eave baffles (WSEBs) that were either untreated (U) or treated (T) with PM plus binding agent (BA) in the 4 experimental huts over each rotation replicate cycle of 4 days, with all huts being occupied each night by 2 adult male volunteers sleeping under a pyrethroid-treated long-lasting insecticidal net
U1, U2, U3, and U4 are WSEB-negative controls treated with BA only, while T1 and T2 are WSEBs treated with 2 g/sq m PM and BA
