Targeting residual malaria vectors in areas where bed nets are already widely used.

Common malaria interventions, notably insecticidal bed nets have significantly reduced disease, by tackling important malaria mosquitoes, especially those that bite people indoors and rest indoors. However, malaria still causes nearly 430,000 deaths annually, mostly African children. This persistent malaria is increasingly acquired from mosquitoes that bite people outside dwellings, can survive on blood from other vertebrates like cattle, are not readily controlled by indoor interventions like bed nets, and are not easily detectable by existing traps.
