The U.S. Bureau of Land Management has halted the use of spring-loaded traps that disperse cyanide powder to kill coyotes and other livestock predators, a practice wildlife advocates have tried to outlaw for decades due to safety concerns.
The M-44 ejector-devices that critics call “cyanide bombs” have unintentionally killed thousands of pets and non-predator wildlife, including endangered species, according to the U.S. Department of Agriculture's Wildlife Services. They have a scented bait and emit a poisonous cloud when triggered by a physical disturbance.
