The use of cyanide bombs for wildlife “control” by state  agencies is allowed in several  states including New Mexico, Texas,  South Dakota,  Wyoming,  and Montana. These devices kill  wildlife and harm people.  According to  the Mountain Lion  Foundation,

these inhumane devices are responsible not only for the deaths of thousands of wild animals every year but are also the cause of serious injury to people.

Carnivores like coyotes [and lions – ed note] are lured in by the smell of bait. When they tug on the bait, the M-44 device is triggered, releasing deadly sodium cyanide   into the animal’s mouth. Unfortunately, any animal or person that triggers these
“bombs” can be seriously injured or killed.
