Brown tree snakes have two weakness: tasty mice and acetaminophen, the active ingredient in Tylenol. For the snakes, acetaminophen is fatal. So the military dosed the dead mice with the drug and blanketed the forest with them. Ideally, the snakes will eat the drugged mice and die. And the dead mice will be memorialized forever in this unlikely triumph of prey over predator.
