Snake Removal Laws in Colorado: What Homeowners Can Legally Do
August 22, 2026
Most people assume that finding a snake in the yard means they’re free to deal with it however they see fit. Under Colorado’s snake removal laws, that assumption is wrong for the vast majority of encounters, and acting on it can turn a startled homeowner into a wildlife law violator within seconds.
Colorado treats nearly every snake species as protected wildlife, which means killing, trapping, or relocating one without following state rules can carry real legal consequences. This guide walks through what you can legally do yourself, which species are off-limits, when permits and professionals come into play, and what happens if the rules get broken.
Important Note: This article summarizes Colorado wildlife regulations for general educational purposes and is not legal advice. Rules can change, and enforcement details vary by county — verify current requirements with Colorado Parks and Wildlife or a licensed attorney before acting.
Is It Legal to Remove or Relocate a Snake Yourself in Colorado
In most situations, no. Colorado law makes it illegal to take, trap, or relocate wildlife — snakes included — without a permit or an applicable rule from the wildlife commission. Killing non-venomous snakes is a violation of the Colorado Revised Statutes Title 33, Wildlife and Parks and Outdoor Recreation § 33-6-109, which prohibits the taking of any wildlife without a permit or a rule of the commission. That statute is the legal backbone behind nearly every snake-related citation issued in the state.
There is one narrow self-help allowance built into Colorado Parks and Wildlife’s herpetofauna rules. A person may relocate any herpetofauna for the safety of the animal or people if it is on a road, trail, or railway, you may move the animal to an unconfined nearby location, and if it is in a house, building, or similar structure, you may also move it to an unconfined nearby location. Outside of those specific circumstances — say, a snake sunning itself in your garden bed with no safety concern — you don’t have blanket permission to scoop it up and drive it elsewhere.
It’s also worth knowing that CPW doesn’t force anyone’s hand here. 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. For a broader breakdown of how this applies to other backyard wildlife beyond snakes, the wildlife removal laws in Colorado guide covers species like raccoons, bears, and migratory birds that follow different rules entirely.
Pro Tip: If a snake is simply passing through your yard and isn’t near a doorway, garage, or high-traffic area, the safest and most legal option is often to leave it alone. Most snake encounters resolve on their own within a day.
Protected Snake Species in Colorado
Colorado’s snake diversity is bigger than most residents realize. Colorado is home to 30 snake species, and they vary from the common garter snake to the colorful ringneck snake. With only a small handful of those being venomous, that leaves dozens of harmless species that spend their entire lives protected under state regulation.
All other snakes are nongame wildlife and are protected by law. This nongame classification falls under Colorado’s broader wildlife statutes, which state plainly that nongame species and subspecies, including threatened or endangered wildlife, are protected and their harassment, taking, or possession is prohibited except as follows. The exceptions that follow are narrow — scientific collecting licenses, rehabilitation licenses, and similar special-purpose permits, not casual backyard removal.
One species causes more confusion than any other. The bull snake (Pituophis catenifer sayi) is a large, thick-bodied constrictor that vibrates its tail and hisses loudly when threatened, a defense mimicking rattlesnake behavior. Often mistaken for rattlesnakes, these beneficial reptiles help control rodent populations throughout Colorado, and state regulations protect native snakes, making it illegal to kill or relocate them without proper permits. Misidentifying a bull snake as venomous and killing it is one of the most common ways homeowners unintentionally break the law.
Rattlesnakes get more legal flexibility, but even among venomous species, protection status varies. The massasauga rattlesnake (Sistrurus catenatus tergeminus) is a smaller, secretive species found in parts of southeastern Colorado. The Massasauga is protected by the U.S. Fish and Wildlife Service under the Endangered Species Act, meaning it cannot be taken from the wild and is not to be messed with. That federal layer sits on top of Colorado’s own state protections, so removing or killing one can trigger both state and federal enforcement.
| Snake Type | Venomous? | Protection Status |
|---|---|---|
| Bull snake, garter snake, racer, and most other native species | No | Nongame wildlife — protected, no killing or relocation without permit |
| Prairie rattlesnake | Yes | May be killed only if it poses a direct threat to safety or property |
| Midget faded rattlesnake | Yes | May be killed only if it poses a direct threat; considered the state’s most toxic species |
| Massasauga rattlesnake | Yes | Protected under both state nongame rules and the federal Endangered Species Act |
Permit Requirements for Snake Removal in Colorado
When a snake situation doesn’t fall under the road, trail, or in-building exception, the legal path forward is a state-issued permit. For every other species, a permit is required, and to relocate all other species you must obtain a Relocation Permit from Colorado Parks and Wildlife. This applies whether the snake is nonvenomous and simply unwelcome, or a rattlesnake that isn’t posing an immediate threat.
Getting a relocation permit isn’t just paperwork — CPW attaches real conditions to where and how the animal can be released:
- You must notify Colorado Parks and Wildlife in advance and secure permission from the landowner or managing agency where the animal will be released ahead of time.
- Relocation sites must be appropriate habitats for the species.
- The release location generally needs to be far enough from populated areas that the snake won’t simply return or become someone else’s problem.
- Records of the permit and release details should be kept in case CPW follows up.
Beyond relocation permits, Colorado’s Nongame Act sets up a wider licensing structure for anyone working with protected species professionally. The Act aims to protect and conserve native species of wildlife that are determined to be threatened or endangered within the state, and the CPW Commission is responsible for administering and enforcing it, including listing and delisting species, issuing permits, and developing conservation programs. That’s the same regulatory body that governs everything from scientific collecting licenses to the permits wildlife control companies rely on. Full details on how this permitting system applies to species beyond snakes are covered in the Colorado wildlife removal laws overview.
When You Can Legally Kill a Snake in Colorado
The legal window for killing a snake in Colorado is narrow and species-specific. In Colorado, it is only legal to kill a rattlesnake if it poses a threat. Every other snake, venomous or not, stays off-limits for lethal action.
Even that rattlesnake exception has limits built in. It is not illegal to kill venomous snakes in Colorado if they pose a threat to human safety or property, but it is illegal to kill venomous snakes in Colorado for any other reason, such as for sport, collection, or commercial purposes. A rattlesnake coiled near a doorway or a child’s play area is a different legal situation than one sunning on a rock at the far edge of a five-acre lot.
Common Mistake: Killing a snake first and identifying it second is backwards from a legal standpoint. Since bull snakes and other harmless species are frequently mistaken for rattlesnakes, confirming the species before taking any lethal action is the difference between a legal act and a wildlife violation.
You might wonder whether a rattlesnake merely being present in your yard counts as a “threat.” CPW’s guidance and the state’s wildlife biologists have consistently pushed back on that broad interpretation. All other snakes are nongame wildlife and are protected by law, and even outside the legal ramifications, going after a snake is generally a bad idea. Snakes rarely strike unless cornered or handled, so distance and patience often resolve the situation without anyone needing to kill anything at all.
Rules for Venomous Snake Removal in Colorado
Even when a rattlesnake qualifies for lethal removal under the threat exception, killing it isn’t the only — or necessarily the best — legal option. Live capture and relocation remain available, provided the person doing it follows the same permit rules that apply to nonvenomous species. While the majority of snakes in the region are non-venomous and pose no threat to humans, encounters with venomous species like the prairie rattlesnake can occur, and prairie rattlesnakes are by far the most commonly encountered venomous species along Colorado’s Front Range and eastern plains.
The midget faded rattlesnake deserves special caution. The midget faded rattlesnake is considered the deadliest snake in the state, found primarily in the canyon country near the Colorado National Monument. Its venom is more potent, ounce for ounce, than many other North American rattlesnake species, which makes DIY handling considerably riskier than the legal question alone suggests.
Because of both the legal complexity and physical danger, wildlife professionals generally recommend against amateur handling of any venomous snake. Snake removal typically involves careful capture, secure containment, and relocation to an appropriate habitat away from residential areas, an approach that aligns with Colorado regulations and best practices for wildlife management. If you keep chickens, that guidance matters even more — rattlesnakes are drawn to coops for eggs and rodents, and the backyard chicken laws in Colorado resource covers predator-proofing rules that reduce these encounters before they start.
Hiring a Licensed Wildlife Removal Operator in Colorado
For most homeowners, the practical answer to a venomous snake problem is calling a professional rather than navigating permits alone. Native Colorado snake species are protected under Colorado Parks & Wildlife regulations, and licensed operators follow CPW rules on every job. That means the permitting burden, species identification, and safe capture equipment all shift to someone trained specifically for it.
A qualified operator typically handles more than just the initial capture:
- Safe identification of the species, distinguishing venomous rattlesnakes from harmless look-alikes like bull snakes.
- Capture using specialized tools and protective equipment rather than makeshift methods.
- Relocation to CPW-appropriate habitat, following the same permit conditions individuals must meet.
- Exclusion work — sealing foundation gaps, vents, and other entry points — to prevent repeat encounters.
- Follow-up guidance on rodent control and habitat modification, since food sources are what draw snakes to a property in the first place.
Key Insight: Hiring a licensed operator doesn’t just solve the immediate snake problem — it insulates you from the legal risk of an improperly handled relocation or a misidentified kill, both of which carry citations under Colorado’s wildlife statutes.
Colorado isn’t unique in requiring this level of oversight. States including California, Arizona, Minnesota, and North Carolina all run comparable licensing systems for wildlife control operators, reflecting a nationwide trend toward professionalizing snake and nuisance wildlife handling rather than leaving it to unregulated DIY methods.
Penalties for Illegally Killing or Relocating a Snake in Colorado
Violating Colorado’s snake removal laws isn’t a minor slap on the wrist — it’s a formal misdemeanor charge with financial and license consequences attached. The base statute lays out a tiered penalty structure depending on the wildlife involved. For each animal listed as endangered or threatened, the fine ranges from not less than two thousand dollars to not more than one hundred thousand dollars, or imprisonment for not more than one year in the county jail, or both, along with an assessment of twenty license suspension points. That top-end penalty tier is exactly why killing a massasauga rattlesnake carries far more legal weight than killing a garter snake.
For nongame species that don’t fall into a specifically listed category — which covers most of Colorado’s nonvenomous snakes — the fines are smaller but still real. For any wildlife not covered by the higher-penalty paragraphs, the fine is fifty dollars and an assessment of five points for the first animal, with an additional fine per additional animal taken or possessed at the same time. Multiple snakes killed or removed in a single incident can add up quickly under this per-animal structure.
License suspension points carry their own long-term cost. Accumulating 20 or more points within a five-year period can result in suspension of hunting and fishing privileges. A single endangered-species violation alone can wipe out that entire five-year point allowance in one citation. Beyond wildlife-specific penalties, inhumane treatment of any animal during a botched removal attempt can also intersect with the state’s broader animal cruelty laws in Colorado, adding a separate layer of legal exposure.
Enforcement generally starts with a wildlife officer citation rather than a criminal investigation, but repeat violations or cases involving federally protected species like the massasauga can escalate quickly. If you’re ever unsure whether a situation qualifies for self-removal, the safer legal move is contacting CPW directly or a licensed local operator before acting — a five-minute phone call is considerably cheaper than a wildlife violation fine.
Snake encounters in Colorado are common enough that most residents will face one eventually, whether it’s a bull snake in the garden or a rattlesnake near a trailhead. Knowing which species are protected, when the rare killing exception applies, and how permits work turns a stressful moment into a manageable one. When a snake shows up dead on a road rather than in your yard, different rules apply entirely — the roadkill laws in Colorado guide covers what’s legal to do in that scenario.
