Bear traps are illegal because the classic steel-jaw leghold device causes extreme injury to whatever it catches, catches animals and people it was never meant to catch, and would unravel the bear population recovery that state and federal agencies have spent decades building. No state in the U.S. permits foothold traps for bears, most states heavily restrict or ban steel-jaw leghold traps for any species, and federal law makes it a separate crime to move or sell wildlife taken in violation of those state rules.
The Injuries These Traps Cause
A steel-jaw leghold trap uses two spring-powered metal jaws that snap shut on an animal’s leg when it steps on a trigger plate. The clamping force is strong enough to break bones, tear tissue, and hold the animal in place until the trapper returns. An animal caught this way suffers through whatever interval passes before the trap is checked, enduring pain, fear, dehydration, and exposure. Where traps are set illegally, no one checks at all, and the animal can die slowly in place.
The direction of U.S. law has moved steadily away from devices that cause this kind of prolonged injury. Even in states that still allow leghold traps for some furbearing species, the rules now typically require padded or offset jaws, cap jaw-size, and set mandatory check intervals.
They Catch Whatever Steps on Them
A leghold trap cannot tell a target animal from a pet, a protected species, or a person. USDA data on foothold trap captures in wildlife damage management shows that roughly 6% of captures are non-target species, including domestic dogs, cats, and livestock.1USDA Animal and Plant Health Inspection Service. Human Health and Ecological Risk Assessment for the Use of Foothold Traps in Wildlife Damage Management Across just six states studied over five years, an average of 779 non-target animals were caught each year, including 31 dogs and 12 cats annually, some of which had to be euthanized because of their injuries.
The same indiscriminate quality creates a human safety problem. A trap hidden under leaves is invisible to a hiker, a hunter, or a child, and stepping on one can break bones and cause serious tissue damage well away from help. That risk feeds directly into the legal picture: someone who sets an illegal trap faces criminal charges for the trap itself and civil liability if a person is injured.
Bear Conservation Would Not Survive Unregulated Trapping
Bear populations in the lower 48 states were decimated by unregulated hunting and trapping through the 19th and early 20th centuries. Rebuilding them has taken decades of harvest quotas, habitat protection, and controlled hunting seasons. A nationwide survey by the Association of Fish and Wildlife Agencies found that while 32 states allow regulated bear hunting, only 9 states allow any capture of bears through trapping at all, and those states limit methods to foot snares or cage-style live-capture traps. Foothold traps are not permitted for bears anywhere.2Association of Fish and Wildlife Agencies. Trapping Regulations Survey and Best Management Practices
What the Laws Actually Prohibit
Trapping regulation operates on two levels. State wildlife agencies decide which traps may be used, which species may be trapped, where, and how often traps must be checked. Federal law then backs those rules by criminalizing interstate trafficking in wildlife taken in violation of them.
State Bans and Restrictions
At least eight states have banned leghold traps outright, several through voter ballot initiatives. Arizona banned traps, snares, and poisons on public lands in 1994. Colorado banned them on all lands in 1996. Washington followed in 2000. Other states permit leghold traps for certain furbearing species but impose jaw-size caps, require padded or offset jaws, or restrict their use near areas with human activity. Bear-specific prohibitions are nearly universal, and the handful of states that allow any bear capture limit trappers to cage-style or culvert devices, usually only in human-wildlife conflict situations rather than for recreation.
Federal Rules on Public Lands
On certain federal lands, 36 C.F.R. ยง 242.26 explicitly prohibits using a trap to take bears and bans conventional steel traps with a jaw spread over nine inches for any species.3eCFR. Code of Federal Regulations Title 36 Section 242.26 Individual national forests and Bureau of Land Management units can add further restrictions on top of that baseline.
The Lacey Act
The Lacey Act makes it a federal crime to transport, sell, or purchase wildlife taken in violation of state or foreign law. A person who traps a bear illegally under state law and then moves the animal or its parts across state lines has committed a separate federal offense.4Office of the Law Revision Counsel. 16 USC 3372 – Prohibited Acts The law also reaches attempts, so the sale or transport does not have to succeed for charges to follow. This gives federal prosecutors a route into cases that state enforcement may lack the resources to pursue.
Penalties for Using an Illegal Trap
State charges for illegal trapping range from misdemeanors to felonies depending on the species involved, whether protected or endangered animals were harmed, and whether the trapper held a license. Fines, license revocation, and forfeiture of equipment are standard. States that assign restitution values to illegally killed wildlife can add thousands of dollars on top of criminal fines, and bears tend to carry high restitution values because of their status as managed big game.
Federal Lacey Act penalties scale with what the offender knew and the value of the wildlife:
- Felony conviction for knowingly importing, exporting, or selling illegally taken wildlife valued over $350: fines up to $20,000 and up to five years in prison.
- Misdemeanor for prohibited conduct where the person should have known the wildlife was illegally taken: fines up to $10,000 and up to one year in prison.
- Civil penalties for negligent violations: fines up to $10,000 per violation.
Convictions also carry forfeiture of equipment used in the offense, which can include traps, vehicles, and firearms.5Office of the Law Revision Counsel. 16 USC 3373 – Penalties and Sanctions
How Agencies Legally Capture Bears
When wildlife agencies need to capture a bear for research, relocation, or conflict management, they use methods designed to hold the animal without injuring it. Culvert traps are large barrel-shaped devices mounted on trailers that lure a bear inside with bait and close a door behind it. Cage traps work on the same principle but are stationary. Foot snares with modern breakaway features use cable loops with stops that prevent over-tightening and release points sized to let non-target animals go. Tranquilizer darts are used by trained personnel when a bear needs to be immobilized quickly, particularly in urban conflict situations. A bear brought in through one of these methods is usually calm enough to be relocated; a bear that has struggled for hours against a steel jaw often cannot.
If You Find a Trap in the Wild
Do not touch a trap or try to disarm it. The U.S. Fish and Wildlife Service recommends keeping a safe distance and documenting what you see: photograph the trap, its surroundings, and any nearby landmarks, and note the date, time, and GPS coordinates if you can.6U.S. Fish & Wildlife Service. How to Report Wildlife Crime
You can submit a tip through the U.S. Fish and Wildlife Service website or call the FWS tips line at 1-844-FWS-TIPS (1-844-397-8477). Your state game warden is another direct option. Reports can be made anonymously, and financial rewards may be available for tips that lead to a successful enforcement action.6U.S. Fish & Wildlife Service. How to Report Wildlife Crime
