Canyon’s Law
United States119th CongressS-2179Senate
Updated: Jun 26, 2025
Summary
This legislation seeks to prohibit the use of M-44 devices , commonly known as "cyanide bombs," on all federal public lands. These devices are designed to propel highly toxic sodium cyanide, a Category One acute toxicant, and are primarily used for predator control against animals like coyotes and foxes. The bill mandates that any federal, state, or county agency must remove all M-44 devices from public lands within 30 days of the Act's enactment. Congress finds that M-44 devices are indiscriminate, posing significant risks to non-target wildlife, including endangered species and family pets, and have caused accidental exposure, injury, and even death to people. Despite their low efficacy in targeting specific animals, these devices continue to be deployed, leading to widespread environmental and public safety concerns.
