“Before the laced mice are airdropped, they are attached to “flotation devices” that each consist of two pieces of cardboard joined by a 4-foot-long (1.2-meter-long) paper streamer. The flotation device was designed to get the bait stuck in upper tree branches, where the brown tree snakes reside, instead of falling to the jungle floor, where the drug-laden mice might inadvertently get eaten by nontarget species, such as monitor lizards. There are few other species on Guam that could be tempted by the mouse bait, USDA’s Savarie said, because the brown tree snakes have eaten most of them.”
