Its Raining Dead Mice in Guam

Guam, the U.S. territory, is being overrun with brown tree snakes -- some 2 million -- that have decimated the populations of other critters on the Pacific island. The latest effort to rid the isle of its slithery pestilence involves dropping dead mice loaded up with painkillers from helicopters during April and May.  The idea is that the mice will get stuck in jungle foliage, and the snakes will die from eating the poisoned rodents.  I love science, but has anyone consider what other creatures might eat the mice?
