Year after year, mosquitoes hold the title of potentially being the world’s most deadliest animals (Gorney, 2016). As small as they are, female mosquitoes serve as vectors for a host of illnesses, including malaria, spread by the Plasmodium parasite (World Health Organization [WHO], 2019). Despite monumental strides in reducing the burden of malaria through tools like bednets, the rate of these gains is slowing and may do so even further because of disruptions from the ongoing COVID-19 pandemic (WHO, 2019; Kretchmer, 2020). To investigate additional means of climbing over this hurdle, this review examined the efficacy of insecticide-treated window screens or eaves to lower mosquito bites, mosquito entry, and their prevalence. One reviewer searched PubMed and Scopus databases on March 11, 2020 for relevant peer-reviewed studies that were reported in English from malaria-endemic countries and were published between 2000-2020. Ultimately, 11 out of 724 initial articles were included in the final review. The ensuing results suggest that there is value in using treated eave tubes or window screens. Specifically, eaves treated with beta-cyfluthrin, transfluthrin, or bendiocarb produce vast drops in blood-feeding, biting, or mosquito prevalence (Barreaux et al., 2018; Mmbando et al., 2018; Stenberg et al., 2016). Co-treating window screens and eaves with polyacrylate-binding agents (BA) with pirimiphos-methyl (PM) also appears to retain insecticidal potency after several washes (Chinula et al., 2018). More data is needed to study the longevity of and household attitudes toward these interventions.
