Listener Gĩtaũ has a serious problem: every so often his home in rural Kenya is invaded by an army of ants. They coat the floors, climb the walls, and rain down on Gĩtaũ and his family while they sleep. Gĩtaũ wants to know: Why are these ants torturing us? Entomologists Dino Martins and Piotr Naskrecki have ant-swers. Special thanks to Caswell Munyai, Caspar Schöning, and Daniel Kronauer.
