Nuisance Wildlife Laws in Colorado: What Property Owners Are Actually Allowed to Do

A raccoon tears through your trash every night. A beaver has flooded your irrigation ditch. A coyote is circling your chickens. Colorado gives you more options than most people realize — but the rules are specific, and the penalties for getting them wrong are real.

Understanding nuisance wildlife laws in Colorado means knowing which animals you can act on, which methods are legal, and where the hard lines are drawn for protected species like black bears and mountain lions. This guide walks you through everything you need to know before you set a trap, fire a shot, or call a professional.

Important Note: Colorado state law sets the minimum framework, but your city, county, or HOA may have stricter rules. Always verify local ordinances before taking any action against nuisance wildlife on your property.

What Counts as Nuisance Wildlife in Colorado

Colorado does not have a single statutory definition that labels a specific animal a “nuisance.” Instead, the determination is left to you as the property owner. Colorado Parks and Wildlife (CPW) does not require nor request the removal of wildlife deemed a nuisance — the determination that a species has become a nuisance and should be removed is the prerogative of the landowner.

In practical terms, an animal becomes a nuisance when it causes damage to your crops, real or personal property, or livestock. Wildlife professionals and CPW guidance group nuisance animals into a few broad behavioral categories:

• Aggressive animals — those displaying threatening behavior toward people or domestic animals, such as bears or mountain lions that repeatedly approach homes
• Nesting animals — species that establish dens or nests inside or against structures, such as wildlife species that nest in or around human habitations, including birds like pigeons or starlings due to their nesting habits
• Foraging animals — those that raid gardens, feeders, or livestock areas; animals that cause disturbances through their feeding habits, such as raiding bird feeders or scavenging in urban areas, include squirrels and deer

The most commonly encountered nuisance species in Colorado include raccoons, coyotes, prairie dogs, pocket gophers, marmots, beavers, muskrats, red foxes, bobcats, skunks, rattlesnakes, and various rodents. Big game species like black bears and mountain lions can also create conflicts, but they operate under a separate and stricter set of rules covered later in this guide.

Key Insight: Colorado state statutes and CPW regulations set the baseline framework, but local laws and ordinances may be more specific about what is allowed at a certain location. It is your responsibility to determine whether a particular method is legal in your city, county, or homeowners association.

Your Rights as a Property Owner in Colorado

Colorado law gives landowners meaningful authority to deal with wildlife that is actively damaging their property — but that authority is tied directly to documented damage, not mere presence or inconvenience.

If wildlife is causing damage to crops, real or personal property, or livestock, a person — or any employee or agent of the landowner — may hunt, trap, or take a broad list of species on lands owned or leased by that person without securing a license. This list includes black-billed magpies, common crows, starlings, English or house sparrows, common pigeons, coyotes, bobcats, red foxes, raccoons, jackrabbits, badgers, marmots, prairie dogs, pocket gophers, Richardson’s ground squirrels, rock squirrels, thirteen-lined ground squirrels, porcupines, crayfish, tiger salamanders, muskrats, beavers, exotic wildlife, and common snapping turtles.

Additional species you may take without a license when they are causing damage include tree squirrels, cottontail rabbits, bats, mice (except Preble’s meadow jumping mouse), opossums, voles, rats, and ground squirrels.

Two species carry an even broader authorization: any person may kill rattlesnakes and skunks when necessary to protect life or property. These do not require a damage threshold — the threat to life or property is sufficient justification.

One critical ownership rule applies to any animal you take: any wildlife killed shall remain the property of the state, and such killing shall be reported to the division within five days. You do not get to keep or sell the animal, and you are obligated to notify CPW.

Situation	License Required?	Reporting Required?
Raccoon damaging crops on your land	No	Yes, within 5 days if killed
Coyote threatening livestock	No	Yes, within 5 days if killed
Rattlesnake posing threat to life	No	Yes, within 5 days if killed
Black bear causing property damage	CPW authorization needed	Yes, within 5 days if killed
Bobcat taken for damage control	No (pelt must be sealed within 30 days)	Yes, within 5 days if killed

Legal Methods for Removing Nuisance Wildlife in Colorado

Even when you have the right to act, Colorado law restricts which removal methods are lawful. Using the wrong method — even on a species you are legally allowed to remove — can expose you to penalties.

Firearms are the most common method of controlling nuisance species, though other methods may be used. You must check with your local authorities on the laws that apply to discharging a firearm. Many municipalities prohibit firearm discharge within city limits, so this option is often limited to rural and unincorporated areas.

When it comes to trapping, the law is strict: the only types of traps that may be used are live traps (cage or box traps). Body-grip traps, leg-hold traps, and snares are generally not permitted for property owners dealing with nuisance animals outside of a licensed furbearer trapping context.

Small game and furbearers captured in live traps cannot be moved from the capture site and must be killed or released on site when the trap is checked — except for cottontail rabbits, tree squirrels, or raccoons. This is a key rule that surprises many property owners who assume they can simply drive a trapped animal to a new location.

Toxicants and poisons represent a third category of legal methods, but with tight restrictions. Some toxicants are legal for Richardson’s ground squirrel, rock squirrel, thirteen-lined ground squirrel, pocket gopher, marmots, black-tailed, white-tailed, and Gunnison prairie dogs when causing damage on private property. Most rats and mice also fall under this category. Poisons may only be used for species indicated on the label, and application directions must be followed for the poison to be lawful. Regardless of whether a toxicant is legal by statute, it is your responsibility to check with local authorities about restrictions at your specific location.

Beyond lethal and trapping methods, non-lethal deterrents are always an option and often the preferred first step. Two key methods for wildlife control are wildlife exclusion and habitat modification. These include implementing deterrents such as motion-activated sprinklers, using sound devices to deter wildlife, installing fences or barriers, and removing attractants like food sources that may draw wildlife closer to human habitats.

Pro Tip: Before investing in traps or other removal tools, secure your property first. Removing food attractants — unsecured trash, pet food left outside, fallen fruit — is the single most effective way to reduce wildlife conflicts, especially with bears and raccoons.

Relocation Rules in Colorado

Many property owners assume that trapping an animal and releasing it somewhere else is the humane and legal solution. In Colorado, relocation is heavily restricted and, for many species, not permitted at all.

For most small game and furbearers caught in live traps, the rule is clear: the animal must be killed or released on site. Relocating a trapped animal to another property — even nearby — is not allowed without meeting specific conditions. The species that may be relocated without a permit are limited, and each comes with its own distance requirement.

For raccoons, relocation is allowed only if all of the following conditions are met: CPW has been notified in advance; the relocation site is appropriate habitat for the species; permission has been obtained from the landowner or managing agency where the animal will be released; and the relocation must occur within 2 miles of the capture site.

For tree squirrels and cottontail rabbits, the rules are similar but the permitted distance is greater: the relocation must occur within 10 miles of the capture site for squirrels and rabbits and within 2 miles for raccoons.

Skunks are in a category of their own. Any person may kill skunks when necessary to protect life or property. State health laws do not permit relocation. Because skunks are a primary vector for rabies in Colorado, releasing a trapped skunk anywhere is not a legal option.

Common Mistake: Driving a trapped raccoon or squirrel to a park or open space and releasing it may seem harmless, but it likely violates Colorado’s relocation rules if you did not notify CPW in advance, lack landowner permission at the release site, or exceed the permitted distance from capture.

For species not covered by the permit-free relocation rules — including most furbearers — you must contact CPW before any relocation attempt. Releasing wildlife without authorization can result in misdemeanor charges under Colorado Revised Statutes. You can learn how neighboring states handle similar situations by reviewing wildlife removal laws in Arizona or comparable state frameworks for context.

Species With Special Rules in Colorado

Several species in Colorado fall outside the standard nuisance wildlife framework and require you to understand a distinct set of rules before taking any action.

Black Bears

Black bears are among the most common large wildlife conflicts in Colorado, particularly in mountain communities. The rules here are strict and frequently misunderstood. Black bears cannot be destroyed when they are causing damage to personal property. Black bears can be killed only when it is necessary to prevent them from inflicting death, damage, or injury to livestock, human life, real property, or a motor vehicle.

The distinction between “personal property” and “real property” matters enormously here. Personal property means everything subject to ownership other than real estate — it includes moveable and tangible things such as animals, furniture, and merchandise. This means a bear that destroys your outdoor furniture, breaks into your car, or kills your dog does not legally justify lethal force. A bear that is actively threatening your life, your home structure, or your livestock does.

CPW categorizes black bear incidents into three distinct types: nuisance bears, depredating bears, and dangerous bears, each with their own management considerations. Nuisance bears are those which pose an immediate threat or damage to property but do not threaten public safety. Dangerous bears are those which pose an immediate threat to human health and safety.

The Game Damage Program is a CPW prevention and reimbursement program that compensates ranchers, farmers, and landowners for damage caused by wildlife. While it does not cover damage caused by nuisance species, it does apply to damage caused by big game, including black bear and mountain lion. If a bear is destroying your livestock or crops, this program may be worth pursuing before taking lethal action.

Mountain Lions

Mountain lions follow the same basic framework as black bears. Mountain lions cannot be destroyed when they are causing damage to personal property. They can be killed only when it is necessary to prevent them from inflicting death, damage, or injury to livestock, human life, real property, or a motor vehicle. Any wildlife killed shall remain the property of the state, and such killing shall be reported to the division within five days.

Bobcats

Bobcats may be taken without a permit on private property experiencing damage, but they carry an additional compliance step: all bobcats, or their pelts, shall be personally presented for inspection and must be sealed within 30 days after take, with a seal provided by the Division. Failing to seal a bobcat pelt is a separate violation from the taking itself.

Federally Protected Birds

Colorado’s list of birds you can take without a license — magpies, crows, starlings, house sparrows, and common pigeons — is limited to non-native or unprotected species. Nearly all other wild birds are protected under the federal Migratory Bird Treaty Act, which operates independently of state law. You cannot trap, kill, or disturb the nests of protected migratory birds regardless of the damage they cause without a federal permit.

Preble’s Meadow Jumping Mouse

This species is federally listed as threatened under the Endangered Species Act. Mice may be taken under the nuisance wildlife provisions, except for the Preble’s meadow jumping mouse. Any action that harms, harasses, or kills this species — or destroys its habitat — can result in federal charges entirely separate from state wildlife law.

Important Note: Colorado’s wolf reintroduction program, ongoing since 2023, has added gray wolves to the landscape in certain parts of the state. Wolves are federally protected under the Endangered Species Act. Contact CPW immediately if wolves are causing livestock depredation — do not attempt to remove or harm them independently. CPW’s Wolf-Livestock Conflict Minimization Program provides resources and support for affected landowners.

When You Need a Licensed Wildlife Control Operator in Colorado

There are situations where handling a wildlife problem yourself is either legally prohibited, practically dangerous, or both. Knowing when to call a licensed professional protects you legally and ensures the animal is handled correctly.

You should contact a licensed wildlife control operator (NWCO) or CPW directly in these circumstances:

• Black bears or mountain lions on your property — Unless there is an immediate threat to human life or livestock, you cannot legally take these animals yourself. CPW must be involved in any removal or lethal action.
• Any species you cannot identify — Taking a protected or federally listed species by mistake carries serious penalties. A professional can identify the animal and advise on legal options.
• Animals in structures — Removing wildlife from inside walls, attics, or crawlspaces often requires exclusion work that must be done correctly to avoid trapping animals inside or creating re-entry points.
• Rabies-risk species — Bats, skunks, and raccoons are the primary rabies vectors in Colorado. Handling these animals without proper equipment and training creates significant health risk.
• Situations requiring a depredation permit — Some removal actions for species not on the permit-free list require a CPW depredation permit, which a licensed operator can help you obtain.

The National Animal Damage Control Association, in conjunction with the International Association of Fish and Wildlife Agencies, has undertaken the task of developing proposed minimum licensing standards for nuisance wildlife control operators. When hiring a contractor in Colorado, verify that they hold the appropriate CPW permits and are fully insured, including liability and workers’ compensation coverage.

For context on how professional licensing requirements compare in other states, see how Washington handles wildlife removal licensing or review the wildlife removal laws in Florida, where operator licensing requirements are among the most detailed in the country.

Pro Tip: Before hiring any wildlife control company, ask specifically whether they are permitted by CPW to handle the species causing your problem. A general pest control license does not authorize wildlife removal in Colorado.

Penalties for Violating Nuisance Wildlife Laws in Colorado

Colorado takes wildlife law violations seriously, and the penalties scale significantly based on the species involved. Acting outside the boundaries of what is legally permitted — even with good intentions — can result in fines, license suspension, and in serious cases, criminal charges.

For violations involving the illegal release of wildlife, any person who violates the release provisions is guilty of a misdemeanor and shall be punished by a fine of two hundred dollars for violations involving native wildlife, and by a fine of not less than two hundred fifty dollars nor more than one thousand dollars for violations involving nonnative or exotic wildlife. In addition, five license suspension points per incident may be assessed by the division against an individual’s license privileges.

For the unlawful taking of big game species — the category that includes black bears and mountain lions — the civil penalties are steep: for each elk, bear, moose, or mountain lion, a fine of one thousand dollars and an assessment of fifteen license suspension points.

When multiple animals are involved, penalties escalate sharply: for violations where any combination of three or more animals are taken or possessed, the minimum fine per animal can reach up to ten thousand dollars per animal, or imprisonment for not more than one year in the county jail, or both. Upon conviction, the commission may suspend any or all license privileges of the person for a period of one year to life.

Beyond fines and license suspension, CPW has the authority to pursue civil recovery for the value of any wildlife unlawfully taken. The division may bring and maintain a civil action against any person, in the name of the people of the state, to recover possession or value or both possession and value of any wildlife taken in violation of articles 1 to 6 of this title.

Equipment used in illegal wildlife activity is also at risk. Every motor vehicle, firearm, trap, explosive, poisonous or stupefying substance, or other personal property used in the hunting, taking, or harassing of wildlife in violation of state law is declared a public nuisance and is subject to seizure, confiscation, and forfeiture or destruction.

Violation Type	Penalty Range	License Points
Illegal release of native wildlife	$200 fine (misdemeanor)	5 points
Illegal release of exotic/nonnative wildlife	$250–$1,000 fine (misdemeanor)	5 points
Unlawful take of black bear or mountain lion	$1,000 fine (civil)	15 points
3+ big game animals unlawfully taken	Up to $10,000/animal + up to 1 year jail	Potential lifetime suspension
Harassing wildlife with a dog	$200 fine (petty offense)	10 points

Colorado’s penalty structure reflects a straightforward principle: the more protected the species and the more deliberate the violation, the heavier the consequence. If you are uncertain whether a particular action is legal, contacting CPW before acting is always the right call.

For a broader look at how Colorado’s animal laws work across different contexts, you may also find it useful to review Colorado’s dog leash laws, roadkill laws in Colorado, and Colorado’s pet import laws. For comparison with how other states structure their nuisance wildlife frameworks, see the wildlife removal laws in Georgia, California’s wildlife removal laws, and New York’s wildlife removal laws.

The core takeaway from Colorado’s nuisance wildlife laws is straightforward: you have real authority to protect your property, but that authority is bounded by species-specific rules, method restrictions, and reporting obligations. Acting within those boundaries keeps you on the right side of the law — and helps ensure Colorado’s wildlife populations remain intact for the long term.
