Malaria mosquitoes have been shown to have a preference for entering houses through the gap between the roof and the walls of houses (called the ‘eave’). We observed that in Tanzania >75% of the houses are being made from brick walls and corrugated sheets. This offers opportunities to close the eaves and install so-called Eave Tubes.

An airstream can pass through the Eave Tube, attracting mosquitoes with the human smells from inside the house. Mosquitoes are blocked via a netting patch treated with insecticides when they try to enter the house through the Tube. Even short body contact with the gauze inside the Tubes effectively kills the mosquito.

Eave Tubes are low-tech tools that can complement the use of bednets and extent the personal protection to the entire household. Eave Tubes only use very small pieces of netting, which leads to an enormous reduction in the amount of insecticides that are used.  Being at eave height, netting is safely out of reach of house occupants and children, which enables the use of novel (resistance-breaking) bioactives. The additional benefit of improved airflow and the ability to also target nuisance mosquitoes can potentially stimulate the uptake of this MCD product by end users.

  • Blocks mosquito house entry
  • Takes advantage of heat, CO2 and host odours from inhabitants
  • Can be incorporated into house construction and provide additional ventilation benefits
  • Made form cheap, locally available/easy-to-ship materials and designed for mass-production
  • Minimises human contact with control agents
