The developers of an innovative outdoor decoy device that uses the odour of smelly socks or a similar synthetic smell to lure and kill malaria-carrying mosquitoes, have just won a grant to test their design and then take it from the lab through production to market. Grand Challenges Canada and the Bill & Melinda Gates Foundation have jointly awarded Tanzanian entomologist Dr. Fredros Okumu and his team at the Ifakara Health Institute in Tanzania, East Africa, the grant in order eventually for their mosquito traps to be available at low cost to the communities that most need them.
