A new study from Tanzania's Ifakara Health Institute has shown that larvicides can be just as effective as bed-nets, yet four times cheaper.
The study focussed on urban areas in Dar es Salaam, where larvicides are having a considerable effect in reducing malaria.
Malaria rates in children under five, the most vulnerable demographic to the disease, fell by 72 per cent following the application of larvicides.
One resident commented: "I can't tell the amount of mosquitoes we used to have here. They have helped us to do away with this nuisance."
