Insecticide treated nets (ITNs) have been shown to reduce malaria related morbidity and mortality and are increasingly being scaled up throughout sub-Saharan Africa. However, ITNs alone are unlikely to reduce transmission to zero in most settings and additional vector control tools are necessary. One new promising strategy is the use of insecticide treated wall liners (ITWLs). These are textiles treated with an insecticide that are used to line the inner walls of houses. The wall liners are considered a long-lasting alternative to indoor residual spraying which is also used for malaria vector control but is expensive to implement.
