Note: ITN = insecticide-treated net (deltamethrin at 25 mg/m²); PPWI 1/3 = top third of the walls covered with woven polypropylene treated with bendiocarb at 200 mg/m²; PPWI total = walls completely covered with woven polypropylene treated with bendiocarb at 200 mg/m². Values in the same row sharing the same superscript letter do not differ significantly (p > 0.05).
