The team discovered that mosquitoes are attracted to the smell of stinky feet.
So in an effort to cut back on the spread of malaria, scientists developed a potent serum, similar to that of human foot odor, to lure and kill mosquitoes.
The synthetic smell is used outdoors in so-called mosquito landing boxes.
Malaria kills about 800,000 people a year. Most of the victims are children in Africa.
