Snake Removal Laws in South Dakota: What Property Owners Need to Know

Finding a snake in your yard, garage, or basement in South Dakota rarely means you’re breaking the law by dealing with it yourself. Unlike states with long lists of protected reptiles, South Dakota’s snake removal laws leave most native species outside specific state regulation, putting the decision squarely in the property owner’s hands. That doesn’t mean the rules are a free-for-all, though — a small handful of protected species, permit triggers, and local ordinances still shape what you can legally do.

This guide walks through exactly where South Dakota law draws the line: which snakes you can remove or relocate without a second thought, which ones require a permit first, and when calling a professional is the smarter move.

Is It Legal to Remove or Relocate a Snake Yourself in South Dakota

For the vast majority of snakes you’ll encounter around a South Dakota property, yes — you can remove or relocate them yourself. The state does not maintain a broad, species-by-species snake protection statute the way some neighboring states do. Most bullsnakes, garter snakes, racers, and milk snakes fall outside any specific take restriction, meaning a homeowner can scoop one into a bucket and release it elsewhere on their own land without applying for anything.

That said, “legal to remove” and “legal everywhere” aren’t the same thing. If you’re relocating a snake off your property, you generally need to stay within South Dakota and avoid dropping it on land you don’t have permission to access. Timing matters too — snake activity in South Dakota peaks in warmer months, which is when most removal calls and questions happen.

The self-help approach mirrors how South Dakota treats other nuisance wildlife on private property. Similar to rules governing a neighbor’s cat wandering onto your yard, the default assumption under state law is that property owners bear primary responsibility for managing everyday wildlife conflicts before involving any agency.

Pro Tip: Before relocating any snake, take a photo first. If you’re ever asked whether the species was protected, a clear photo makes identification — and your defense — much easier.

Protected Snake Species in South Dakota

South Dakota’s protected reptile list is short, which is good news for anyone dealing with a common backyard snake. According to the state’s administrative rules, only two reptiles carry threatened status statewide: the false map turtle (Graptemys pseudogeographica) and the eastern hognose snake. Reptiles classified as threatened in the state are the false map turtle, Graptemys pseudogeographica, and the Eastern hognose snake, Heterodon platirhinos.

The eastern hognose snake (Heterodon platirhinos) is the one species on this list most likely to show up in a residential yard. It’s often mistaken for a venomous species because of its dramatic defensive display — flattening its head, hissing, and even playing dead — but it poses no real danger to people. If you suspect you’ve found one, it’s worth pausing before removal, since threatened status means capturing or destroying it without authorization carries real legal weight.

Beyond that single listed snake, most of South Dakota’s other native species are unprotected under state statute. That includes the state’s other well-known residents. If you’ve spotted an unusually colored specimen and wondered whether it’s something exotic, green snakes in South Dakota are a good example of a species that generates curiosity but carries no special legal protection. The same goes for the harmless milk snake, which is frequently mistaken for something more dangerous — a myth also worth clearing up if you’ve heard rumors about coral snakes turning up in South Dakota. They haven’t, and reptile experts note that coral snakes are not found within about 700 miles of South Dakota. Here’s a quick reference for common species and their general legal status:

Species	Venomous	State Protection Status
Bullsnake	No	Unprotected
Prairie Rattlesnake	Yes	Not state-listed
Red & Pale Milk Snake	No	Unprotected
Plains & Common Garter Snake	No	Unprotected
Racer	No	Unprotected
Eastern Hognose Snake	No	Threatened

Permit Requirements for Snake Removal in South Dakota

Permits only enter the picture once a threatened or endangered species is involved. Under state law, South Dakota’s endangered species statute allows endangered or threatened species found on the state list to be removed, captured, or destroyed pursuant to a permit issued by the secretary of game, fish and parks, upon good cause shown and where necessary to alleviate property damage or protect health.

In practice, this means a homeowner who repeatedly finds an eastern hognose snake denning near a foundation can’t simply relocate or destroy it without going through the South Dakota Department of Game, Fish and Parks first. The permit process exists specifically to balance property owner concerns against the state’s conservation obligations for its shortest list of protected reptiles.

Permit questions come up most often around venomous species too, since ownership and handling carry their own layer of scrutiny. If you’re weighing whether you’d ever need documentation to keep a snake you’ve captured rather than release it, it helps to review the rules on owning a venomous snake in South Dakota before making that call. The same applies if a snake was brought in from outside the state — South Dakota’s broader pet import laws can intersect with wildlife permitting when a captured animal crosses state lines.

Important Note: Permit decisions are made case by case by South Dakota Game, Fish and Parks. Contact the department directly before assuming a permit will be granted, especially for repeated property damage claims.

When You Can Legally Kill a Snake in South Dakota

Because most South Dakota snakes carry no protected status, landowners generally have legal room to kill a nonvenomous, non-listed snake on their own property without a permit. This isn’t spelled out as a blanket “open season” the way big game hunting is — it’s more that the absence of protective statute leaves the decision to the property owner by default.

That default shifts sharply for the two threatened reptiles. Killing an eastern hognose snake or false map turtle without a permit is a violation, full stop, regardless of how the encounter happened. There is one narrow safety valve built into the law: state statute permits an emergency exception. Carnivorous animals found on the state list may be removed, captured, or destroyed by any person in emergency situations involving an immediate threat to human life, provided that the removal, capture, or destruction is reported to the secretary or a representative within twenty-four hours of the act. That provision is meant as a last resort, not routine cover for nuisance complaints.

It’s also worth noting what South Dakota’s animal damage control framework does — and doesn’t — cover. The state’s predator control statutes coordinate control of animals injurious to livestock and property, but the Department of Game, Fish and Parks and the U.S. Fish and Wildlife Service focus that cooperative program on coyotes, feral dogs, fox, prairie dogs, and other wild animals — not snakes. If you’re trying to understand how general hunting regulations interact with wildlife you’d rather not deal with, the state’s hunting laws are a useful companion reference, since snakes aren’t classified as game species requiring a license to take on your own land. Snakes killed unintentionally, such as those struck by vehicles, fall under a separate framework covered in South Dakota’s roadkill laws.

Rules for Venomous Snake Removal in South Dakota

South Dakota has exactly one venomous species to worry about: the prairie rattlesnake (Crotalus viridis). Wildlife biologists confirm it is the state’s only venomous snake, and the Prairie Rattlesnake is South Dakota’s only venomous snake. It ranges through the western and central parts of the state, favoring rocky outcrops, grasslands, and stream banks.

Here’s something that surprises many South Dakotans: the prairie rattlesnake isn’t a state-monitored or protected species. According to the state’s herpetological reference database, South Dakota’s status listing for the species confirms this species is not monitored by South Dakota Game, Fish and Parks, even though the Prairie Rattlesnake is the state’s only snake that can be dangerous to people. That combination — dangerous but unprotected — means removal and killing decisions for rattlesnakes rest almost entirely with the person who encounters one, without the permit hurdle that applies to threatened species.

Practically speaking, that doesn’t make removal a good DIY project for most homeowners. Rattlesnake bites are a genuine medical emergency, and misidentification is common — several harmless species get mistaken for rattlesnakes because of similar defensive tail-shaking behavior, even though only the true rattlesnake carries functioning venom glands.

Important Note: Older reference materials on venomous reptile ownership sometimes cite licensing requirements for South Dakota that don’t clearly match current statute. Always confirm venomous snake handling or possession rules directly with South Dakota Game, Fish and Parks rather than relying on secondhand lists.

If a rattlesnake has taken up residence near a home, foundation, or barn, this is generally the scenario where professional removal makes the most sense rather than attempting a DIY relocation.

Hiring a Licensed Wildlife Removal Operator in South Dakota

South Dakota doesn’t run a centralized state licensing board specifically for snake removal the way it does for hunting guides, but licensed and insured nuisance wildlife control operators are active throughout the state and regularly field snake calls alongside more common complaints. These operators typically handle conflicts between people and wildlife, and deal with conflicts between people and wildlife such as squirrels living in an attic or raccoons digging through the trash, with licensed and insured professionals available to resolve the problem.

Hiring a professional is worth strong consideration in a few common scenarios:

• A suspected prairie rattlesnake has taken up residence near a home entrance, deck, or barn
• You’re unsure whether a snake is the protected eastern hognose species before taking any action
• Repeated snake encounters suggest a den site rather than a single wandering individual
• Young children, elderly residents, or pets regularly use the affected outdoor space

Before hiring anyone, ask directly whether they carry liability insurance and whether they’re familiar with South Dakota’s threatened species list — a reputable operator should be able to identify an eastern hognose snake on sight and explain why it can’t simply be relocated without a permit. This same property-owner-first structure shows up elsewhere in South Dakota animal law, including how wandering pets and nuisance animals are handled before any government agency gets involved.

Pro Tip: Get a written estimate and species-identification confirmation before any removal work begins, especially for jobs quoted as “snake removal” without specifying which species was actually found.

Penalties for Illegally Killing or Relocating a Snake in South Dakota

Penalties in South Dakota scale with which snake is involved. For the state’s two threatened reptiles, unauthorized capture, destruction, or possession is treated seriously under state code. The relevant statute frames unauthorized activity involving listed species as a misdemeanor, and importation, possession, sale, or purchase of an endangered or threatened species without the required permit, license, or documentation is classified as a violation carrying misdemeanor penalties. A separate provision covers permit misuse more broadly: permits for the capture or destruction of wildlife to protect life or property come with their own violation standards, alongside the emergency provision for protecting human life.

For unlisted, unprotected species like bullsnakes, garter snakes, and prairie rattlesnakes, there’s generally no state wildlife penalty tied to killing or relocating them on your own property — but local ordinances can still apply. South Dakota enforcement of animal-related rules isn’t limited to protected wildlife; a Sioux Falls man learned this when he was cited under a local animal-at-large ordinance for letting his pet ball python move freely in a public park. Reporting on the case noted that the man was fined $190 for allowing his pet snake to slither freely in the park after he was ticketed for animals running at large. It’s a different scenario than wild snake removal, but it shows South Dakota authorities do actively enforce animal ordinances even when a snake — rather than a dog or cat — is involved.

Important Note: This article provides general legal information, not legal advice. Wildlife statutes and local ordinances change, and penalty amounts can vary by county and circumstance. Confirm current requirements with South Dakota Game, Fish and Parks or a licensed attorney before acting on a specific situation.

The bottom line for most South Dakota property owners: everyday snake encounters rarely require a permit or invite a penalty, but the moment a threatened species or a public-safety situation is involved, the legal stakes rise quickly. Knowing which category your snake falls into — before you act — is the difference between a routine backyard problem and a citation.
