The long-lasting insecticidal nets (LLINs) have been promulgated to compensate the low re-impregnation rate of conventional mosquito nets. Today, the cornerstone of the fight against malaria vectors is based on a large distribution of these LLINs for universal coverage. Despite this promotion, the question of their effective life in operational conditions remains unresolved. Between September and October 2013, a survey was conducted in 11 districts of Senegal where LLINs were sampled and routed to the laboratory for assessing their physical integrity and biological effectiveness. A total of 207 LLINs that were sampled in the 11 districts have been monitored during this study. Our results showed that Olyset® Net and PermaNet® 2.0 are the most represented brands in the districts. These two major brands have a good biological efficiency providing a high rate of knockdown despite their failing physical integrity.
