One Tiny Fly Is Winning Israel's War on Invasive Ants

Somewhere in Israel right now, a fire ant is walking away from its own nest, and it has no idea why. It was carrying food a moment ago. Then it stopped, dropped it, and turned around, as if something reached inside its skull and rewrote the map. Hours later it falls, and its head separates cleanly from its body. Go back to that nest and you will find hundreds more, hundreds of bodies, hundreds of heads lying beside them, every one killed the same way. Israel has been losing this war for twenty years. What is finally turning it around is smaller than a grain of rice, and it is not on our side by accident.
