Malaria is one of the most common parasitic diseases in the world and probably one of the deadliest of all human affections. The fact that people sleep after 10 pm and that mosquitoes swarm already at about 6 pm leads us to other options such as the use of insecticide-treated plastic sheeting in reducing malaria transmission in the commune of Aguégués. The insecticide-treated plastic sheeting were employed on the inside walls of 291 dwellings in the treated zone, where the mosquitoes land after biting. Entomological and parasitological parameters were studied. Human aggressive density (m.a) of anophelines has been a crude reduction to 87.26%. Corrected reduction was 85.78%. The crude reduction of the parous rate of Anopheles gambiae S.I. was 38.3%. Corrected reduction was 45%. The crude reduction of sporozoite index is 25% and the corrected reduction was 40%. The crude reduction for the number of infective bites per man is 90% and the corrected reduction was 88.88%. In residual fauna, the crude reduction of indoor residual density (IRD) was 86.5%. The corrected reduction was 90.3%. The introduction of insecticide treated plastic sheeting has significantly reduced the incidence of positive slides which is 2.69%. The crude reduction was 92.8% and the corrected reduction was 92.76%. The installation of insecticide-treated plastic sheeting in Akpadon in 2011 has significantly corrected hemoglobin levels. The insecticide-treated plastic sheeting provide a shelter “zero fly” which play an important role in reducing malaria transmission in the commune of Aguégués in Bénin.
