Malaria remains one of the major threats to public health and economic development in Tanzania and is still the leading cause of morbidity and mortality in the country. While decades of efforts to control the disease have cut deaths from malaria by half, 93 per cent of Tanzanians remain at high risk according to the World Health Organization. As mosquitoes continue to develop resistance to insecticides, the fight against malaria is becoming more complex and increasingly expensive.

In response, the Ifakara Health Institute (IHI) has developed a cost-effective control method capable of targeting even the most resilient mosquitoes. It involves placing special six-inch diameter plastic pipes in walls underneath the roof of houses. These ‘eave tubes’ have a unique type of netting fitted inside that allows for the use of insecticides in powder form in quantities far below those required for bed nets. The eave tubes also allow for the application of alternative chemicals, even those that are not recommended for application on bed nets, either in combination or rotation.
