Recently, the Trump Administration reauthorized the use of M-44 poison devices for use in wildlife culls. These devices, also referred to as “cyanide bombs,” are planted in the wild and designed to lure in predators that threaten livestock with bait, then release a fatal dose of sodium cyanide, a highly toxic pesticide. The devices are smeared with scented bait, which cause animals to bite on and pull them. This causes a capsule containing the sodium cyanide is then ejected into their mouth. Deaths caused by the poisoning from these traps are agonizing. Use of M-44 devices gained some media attention when a fourteen-year-old boy named Canyon accidentally set off a device while walking his dog, injuring himself and killing his dog. After bending down to touch what looked like a garden sprinkler, the device exploded, shooting poison directly into the boys eyes, with the remainder blowing downwind towards his dog, Casey. Within a minute, Casey was “writhing with convulsions, a reddish foam emanating from his mouth. In front of Canyon, the yellow Lab made guttural sounds then went still.” Casey’s death is not an uncommon occurrence. An investigation uncovered that between 2000 and 2012, activation of these devices resulted in the deaths of 1,200 dogs. These cruel devices cast the same agonizing fate on countless wildlife across the country.
This program is carried out by Wildlife Services, a branch of the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS). Wildlife Services, founded in 1885, exists primarily for the benefit of the livestock industry, spending more than $80 million a year killing animals that are deemed a “nuisance” to humans. The agency uses of poisoned bait, neck snares, leghold traps (which are banned in 80 countries), aerial gunning, and cyanide traps to go after animals that threaten livestock grazing on public lands. Wildlife Services was responsible for the deaths of over 2.5 million animals in 2018.
Wildlife Services, along with its state counterpart agencies in Montana, New Mexico, South Dakota, Texas and Wyoming, have relied on the M-44s to kill animals that threaten livestock since the mid-1970s. These cyanide bombs kill thousands of animals every year, killing 6,579 in 2018 alone. These traps have been criticized not only for being cruel, but indiscriminate, fatally poisoning numerous non-target species, including federally endangered and threatened species.

In 2019, the U.S. Environmental Protection Agency issued a proposed interim decision reauthorizing the use of M-44 devices. The decision was met with thousands of public comments, almost entirely in opposition to reauthorization. As a result of the flood of public opposition, EPA withdrew its reauthorization application for further review. Nevertheless, four months later the agency issued its decision to move forward with reauthorization with a few minor additional restrictions. Those restrictions include a 600-foot buffer around residences (unless there is written permission from the landowner), increasing the buffer from public pathways and roads, and one additional sign within 15 feet of a device. In addition to offering no protection to wildlife, the restrictions have been criticized as insufficient to adequately protect the public, pets, and vulnerable species.
