- Summary results of the impact of insecticide treated nets (ITNs) and indoor residual spray (IRS) treatments on hut frequenting habit, individual exposure to bites and exit rates of An. gambiae and Cx. quinquefasciatus to the verandahs of the huts in Ladji. For each intervention arm (ITN and IRS) and mosquito species, values in columns sharing the same letter superscript do not differ significantly. LC = Lambdacyhalothrin; CM = Chlorpyrifos methyl; DDT = Dichlorodiphenyltrichloroethane
