Snake Removal Laws in Massachusetts: What Homeowners Need to Know
August 7, 2026
If you’ve ever cornered a snake in your garage and thought about scooping it into a bucket and driving it to the woods, Massachusetts law has a surprising answer: doing that could land you in more trouble than just leaving the snake alone. Snake removal laws in Massachusetts protect nearly every native species you’re likely to encounter, and the rules around handling, relocating, or killing a snake are stricter than most homeowners assume.
Whether a garter snake slipped into your basement or you spotted something larger near a stone wall, what you’re legally allowed to do next depends on the species, your intentions, and whether you plan to handle it yourself or call in a licensed professional. This guide walks through each of those scenarios so you know exactly where the line sits.

Is It Legal to Remove or Relocate a Snake Yourself in Massachusetts
Catching a snake in a jar and letting it go a few miles away feels harmless, but Massachusetts treats it as a wildlife violation. It is illegal to transport and release (“translocate”) any wild animal in Massachusetts. That rule applies to snakes just as much as it applies to raccoons or squirrels, and it holds true even when the animal seems perfectly common.
State wildlife officials are direct about why this rule exists. MassWildlife warns not to move wildlife — not only is it illegal, but it’s also ineffective as the animal could return, be in danger in their new environment, or cause problems to someone else. A relocated snake may not know how to find food, water, or shelter in unfamiliar territory, which often means a slower, more painful death than the one you were trying to prevent.
So what should you actually do when a snake shows up? Mass Audubon’s guidance is refreshingly simple. Suburban yards can provide good habitat for snakes, which may seek cover under stairways, shrubs, wood piles, stonewalls, and dense vegetation, and in the vast majority of situations, it’s best to leave the snake alone. If the snake has wandered indoors, the recommended process is just as low-key:
- Close off the room the snake is in so it can’t roam further into the house.
- Open an exterior door or window in that room if one is available.
- Give the snake time and space to find its own way outside.
- If it hasn’t left after a reasonable wait, gently guide it into a box using a broom rather than your hands, then release it just outside.
If you share your yard with dogs that roam near wood piles or stone walls, it’s worth reviewing dog leash laws in Massachusetts as well, since keeping pets on a leash near known snake habitat reduces the odds of a startled bite. Snakes aren’t the only backyard visitors with their own legal framework, either — a dispute over a neighbor’s cat wandering into your yard follows an entirely different set of rules than wildlife encounters do.
Pro Tip: Sealing foundation gaps, gutters, and basement window wells stops most snake-in-the-house calls before they start. Snakes typically follow rodents or insects indoors, so pest control often solves the underlying problem.
Protected Snake Species in Massachusetts
Before you decide how to handle a snake, you need to know what you’re actually looking at, because Massachusetts law treats species very differently. Due to their Endangered Species status, it is illegal to kill, collect, possess or even harass the Timber Rattlesnake, Copperhead, Eastern Hognose Snake, Black Rat Snake, and Worm Snake in Massachusetts. These five species sit at the top of the state’s protection list, and violations carry real legal consequences.
The Timber Rattlesnake (Crotalus horridus) illustrates just how seriously the state takes this. Timber Rattlesnakes have been a species of conservation concern for over 40 years and are protected in Massachusetts through the Massachusetts Endangered Species Act (MESA) since 1990. There are only five remaining populations in Massachusetts, at least two of which are at very high risk of imminent extirpation. The Northern Copperhead (Agkistrodon contortrix) faces similarly narrow habitat in rocky, forested terrain.
Beyond the venomous pair, three other species round out the state’s strictest protections. The Eastern Hognose Snake (Heterodon platirhinos), the Eastern Ratsnake (also called the Black Rat Snake, Pantherophis alleghaniensis), and the Worm Snake (Carphophis amoenus) all fall under the same legal umbrella. According to Mass Audubon, three snake species are listed as Endangered in Massachusetts, and one is listed as Threatened.
Everything else — including the Eastern Garter Snake (Thamnophis sirtalis), the most commonly seen species around homes — falls into a different category. None of Massachusetts’ snakes may be taken from the wild for purposes of sale, regardless of protection status. Common species may be hunted, trapped, or captured up to a possession limit of two.
| Protection Level | Legal Status for Handling | Typical Habitat |
|---|---|---|
| Endangered (Timber Rattlesnake, Copperhead, Black Rat Snake, Worm Snake) | Illegal to kill, collect, possess, or harass | Rocky hillsides, forested uplands, river valleys |
| Specially Protected (Eastern Hognose Snake) | Illegal to kill, collect, or possess | Sandy soils, open fields, woodland edges |
| Common Species (garter, milk, ring-neck, water snakes) | May be captured, up to a possession limit of two; cannot be sold | Yards, stone walls, wood piles, wetlands |

Permit Requirements for Snake Removal in Massachusetts
Permit rules split cleanly along two lines: what you’re allowed to do with a wild snake, and what you’re allowed to keep as a pet. For wild snakes, species not listed as endangered, threatened, or special concern may be taken by hand or hand-held dip net year-round, up to a possession limit of two. Anything above that limit, or any attempt to collect a protected species, requires a special permit that the state issues only in narrow circumstances.
Pet ownership works differently. The only animals you can take out of the wild in Massachusetts are certain reptiles and amphibians under 321 CMR 9.00, and you can keep these as personal pets, but you cannot sell, barter, or exchange them. Dekay’s Brownsnake (Storeria dekayi) is one of the species specifically named on that allowable list, alongside a small number of amphibians.
Venomous species are treated separately from everything else on the pet-ownership side. All venomous snakes require a permit before anyone can legally keep one, a rule confirmed by multiple state wildlife resources covering exotic pet ownership. Non-venomous species purchased through licensed dealers, by contrast, generally don’t require a permit to own.
Key Insight: Permit requirements for keeping a snake as a pet are separate from permit requirements for removing one from your property. A homeowner never needs a personal permit to have a nuisance snake removed — that licensing burden falls on the professional you hire.
When You Can Legally Kill a Snake in Massachusetts
This is the section most homeowners get wrong, so it’s worth stating plainly. Although it is not illegal to kill common snakes in Massachusetts, there is generally no reason for anyone to do so. That narrow allowance applies only to unprotected species like garter snakes, milk snakes, and water snakes — and even then, wildlife officials discourage it because these snakes control rodent and insect populations around homes.
The moment a protected species enters the picture, that allowance disappears entirely. None of the state’s rare snakes — the worm snake, black rat snake, copperhead, and timber rattlesnake — may be collected, killed, or held in possession except under special permit. Killing one of these species by mistake, even out of fear or self-defense, still exposes you to legal liability.
Important Note: Snake identification mistakes happen constantly, especially with juvenile snakes or fast-moving encounters. If you’re not certain a snake is a common species, treat it as protected and leave it alone rather than risk a violation.
Property owners raising backyard poultry sometimes assume predation losses justify killing a snake outright, but Massachusetts doesn’t carve out a blanket exception for that. If egg loss is a recurring issue, reviewing backyard chicken laws in Massachusetts alongside proper coop sealing tends to solve the problem without touching wildlife law at all. The same logic applies to grazing property protected under livestock fence laws in Massachusetts — a secure enclosure keeps both livestock and snakes where they belong.
Accidental deaths, such as a snake struck by a vehicle or lawn equipment, are treated differently from intentional killing since there’s no deliberate act involved. If you’re curious how the state handles animals killed unintentionally in general, the guide to roadkill laws in Massachusetts covers that distinction in more detail.
Rules for Venomous Snake Removal in Massachusetts
Massachusetts has exactly two venomous species, and both get exceptional legal protection alongside the physical danger they pose. Two of the fourteen species of snakes in Massachusetts are venomous — the Timber Rattlesnake and the Northern Copperhead — and both are endangered and require very specific habitats to survive. Mass Audubon confirms just how rare an encounter actually is: the two venomous species prefer rocky, forested hillsides and are very rare across the state.
If you do encounter one, the legal instruction is unambiguous. Do not try to move, capture, or kill the venomous snake, because doing so is illegal — instead, call for help immediately. This isn’t just about legal exposure; both species are protected under MESA, and threats to their small remaining populations include vehicle mortality, incidental and purposeful killing, harassment by curiosity seekers, and collection by poachers.
Because ownership of a venomous snake as a pet also requires state permitting, anyone hoping to legally keep one faces an entirely separate application process on top of removal rules. Our breakdown of whether you can own a venomous snake in Massachusetts walks through what that permitting process actually involves.
Hiring a Licensed Wildlife Removal Operator in Massachusetts
For anything beyond gently sweeping a garter snake out the door, hiring a licensed professional is both the safer and the legally required path. Massachusetts doesn’t let just anyone trap or handle wildlife for a fee. A trapping license and a PAC (Problem Animal Control) license through the state of Massachusetts are both required, and without these, you cannot legally perform the work.
The state also controls how removal happens on a case-by-case basis rather than issuing blanket authorizations. Permits are issued on a case-by-case basis and are only granted when there is a threat to public health and safety, damage to property, or a threat to endangered species. That means a licensed operator handling a snake call in Massachusetts is working within a narrower legal framework than pest control companies in many other states.
This licensing structure isn’t unique to Massachusetts, but the specifics vary widely from one state to the next. Licensed professional snake removal isn’t just about convenience — it’s your best defense against violating wildlife law and regulation that varies wildly from state to state. States like California and Virginia both require professional licensing too, but the permitted methods, species lists, and relocation rules differ enough that a technique legal in one state can be a violation in another.
| Consideration | DIY Approach | Licensed PAC Agent |
|---|---|---|
| Legal for common species (garter, milk snakes) | Yes, within possession limits | Yes |
| Legal for protected or venomous species | No — illegal without a special permit | Yes, with proper licensing |
| Relocation off-property | Illegal under state translocation rules | Regulated exclusion and case-specific handling |
| Liability if misidentified as protected species | Falls entirely on the homeowner | Reduced through professional training |
Ask any operator you’re considering to confirm their PAC license number before work begins — a legitimate business will provide it without hesitation.
Penalties for Illegally Killing or Relocating a Snake in Massachusetts
Massachusetts is one of a handful of states where killing a protected snake carries real legal weight rather than a warning. In states like California, New Jersey, and Massachusetts, killing any native protected snake violates blanket protection laws that carry criminal penalties. That protection extends even to species many people assume are unregulated.
Misidentification isn’t a reliable defense, either. Misidentifying a protected species as a harmless one has cost landowners thousands of dollars in restitution fees in other jurisdictions, and claiming ignorance of the law won’t shield you from prosecution. Massachusetts wildlife officials treat harassment, collection, and killing of endangered species with equal seriousness, and consequences generally include:
- Fines assessed per violation, per animal, in cases involving protected species
- Court costs and potential criminal charges for repeat or willful violations
- Restitution orders tied to habitat or population impact in serious cases
- Confiscation of any illegally collected or possessed snake
Illegal relocation carries its own consequences separate from killing, since transporting and releasing any wild animal in Massachusetts is against the law regardless of the species’ protection status. If you witness what looks like a wildlife law violation — poaching, illegal collection, or harassment of a protected snake — you can report it by calling the state’s toll-free wildlife violation line at 1-800-632-8075.
Pro Tip: Take a photo from a safe distance before contacting a removal professional or reporting a concern. Accurate identification protects you legally and helps wildlife officials respond appropriately.
Snake encounters in Massachusetts almost always resolve without anyone needing to touch the animal at all. Knowing which species you’re dealing with, resisting the urge to relocate it yourself, and calling a licensed PAC agent when removal is genuinely necessary keeps you on the right side of the law while giving the snake — protected or not — its best chance at survival.
