Insecticide-treated eave tubes represent a new tool to dramatically reduce malaria in Africa, where these were recently evaluated in a cluster randomised controlled trial (RCT) funded by the Bill and Melinda Gates Foundation. The technology includes simple pieces of PVC piping, and their installation in otherwise closed eaves under the roof, which form the primary entry point for malaria mosquitoes into houses. Given that the trial in Côte d’Ivoire, also included screening of windows, WHO’s Vector Control Advisory Group (VCAG) has dubbed the combined approach ‘lethal house lure’. Eave tubes, in essence, turn the entire house into a ‘lure and kill’ station, providing protection for everyone inside. Netting inserts, treated with insecticide, result in mosquitoes being killed upon contact when trying to enter the house through the tubes that funnel the indoor human-scented air outwards, luring host-seeking mosquitoes.
