Are chipmunks protected in Pennsylvania? Yes. The Pennsylvania Game Commission classifies chipmunks as protected mammals, so you cannot hunt, trap, or kill them as a matter of course. State law does carve out an exception for property owners dealing with active damage, but that exception comes with rules about how you trap, what you can do with the animal afterward, and what methods are off-limits.
Why Chipmunks Count as Protected
Pennsylvania’s wildlife regulations work by default: any wild mammal that is not designated as a game animal or a furbearer is automatically a protected mammal.1Pennsylvania Game Commission. Chipmunk Chipmunks are neither. They are not game species like squirrels or rabbits, and they are not furbearers like foxes or raccoons. There is no open season on them, and the baseline legal position is that you leave them alone.2Animal Legal & Historical Center. Pennsylvania Code 133 – Wildlife Classification
This is a different status than endangered or threatened. Chipmunks are common statewide and do not trigger federal recovery plans or the strictest conservation mandates. “Protected” here means the exceptions are narrow and the burden is on you to fit inside one.
When a Homeowner Can Legally Kill a Chipmunk
The regulation that applies to most residents is 58 Pa. Code Section 141.3. It removes protection from wildlife (other than migratory birds, big game, and endangered species) when personal property is being destroyed or damaged. Chipmunks burrowing under a foundation, chewing wiring, or undermining a patio or retaining wall all fit. Only the property owner or person in charge of the property can act under this provision. The animal must be taken humanely and lawfully, and the carcass must be turned over to a Game Commission representative if one asks for it.3Pennsylvania General Assembly. Pennsylvania Code Title 34 – Chapter 21 Game or Wildlife Protection
The damage has to be actual or imminent. Preemptive killing because chipmunks might one day cause a problem is not covered. If a game warden asks questions, you will need to show what the animal was doing, so photographs of burrows, structural undermining, or chewed materials before you set a trap are worth taking.
There is a separate provision, Section 2121 of the Game and Wildlife Code, that allows killing wildlife destroying cultivated crops, fruit trees, vegetables, livestock, poultry, or beehives.4Pennsylvania General Assembly. Pennsylvania Code Title 34 Section 2121 – Killing Game or Wildlife to Protect Property It sounds broader than it is. The statute limits who qualifies to people cultivating land as their primary livelihood: farm owners, lessees, family members assisting with cultivation, or farm employees. A backyard vegetable garden does not qualify you. If you are not farming for a living, 141.3 is your legal path, not 2121.
Trapping Rules You Have to Follow
Live-capture wire mesh traps and common rat-sized snap traps are both allowed. Whichever you use, you must visit the trap and release or remove any animal at least once every 36 hours.5Animal Legal & Historical Center. Pennsylvania Code 34 Pa.C.S.A. Game – Chapter 23 Hunting and Furtaking Weekends and holidays count. Leaving a live animal without food or water for days is both inhumane and illegal.
Snap traps need to be placed where children, pets, and non-target wildlife cannot reach them. Setting them inside a small box with openings sized only for chipmunks reduces accidental catches.
What You Can and Can’t Do With a Captured Chipmunk
This is where homeowners most often get themselves into trouble. Catching a chipmunk alive does not give you the right to drive it somewhere else and let it go. Pennsylvania regulations prohibit retaining wildlife alive, selling it, or giving it away. Releasing a chipmunk at a park, on a neighbor’s property, or anywhere off your own land is not legal. The rule exists because relocated animals can spread rabies, parasites, and other diseases into populations that were previously unaffected.
Your two lawful options after a live capture are to release the animal on the same property where you caught it, or to euthanize it humanely. If you euthanize, the carcass must be made available to a Game Commission officer on request.3Pennsylvania General Assembly. Pennsylvania Code Title 34 – Chapter 21 Game or Wildlife Protection Releasing on-site obviously does not solve a persistent problem, which is why many homeowners either use snap traps from the outset or bring in a licensed professional.
Why Poison Is Not a Legal Option
Using rat or mouse poison on chipmunks is one of the most common mistakes, and it can put you in violation of both state and federal law. The Federal Insecticide, Fungicide, and Rodenticide Act makes it illegal to use any pesticide in a way inconsistent with its labeling.6Environmental Protection Agency. Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and Federal Facilities Rodenticides sold for rats and mice are labeled for rats and mice. Applying them to chipmunks violates the label, which violates the law.
Pennsylvania’s Pesticide Control Act reinforces this. A first conviction is a summary offense carrying a fine of up to $300 and up to 90 days in jail. A second violation within three years escalates to a misdemeanor with fines up to $5,000 for commercial applicators or $2,500 for private applicators. The state can also impose civil penalties of up to $10,000 per offense.7Pennsylvania General Assembly. Pennsylvania Pesticide Control Act of 1973
There is also a secondary poisoning problem. Anticoagulant rodenticide stays in a chipmunk’s liver for months. Any hawk, owl, fox, or house cat that eats the poisoned animal absorbs the compound, and repeated sub-lethal doses cause cumulative damage that often kills the predator weeks later.
Penalties for Getting It Wrong
Unlawfully killing or possessing a protected mammal falls under Section 925 of the Game and Wildlife Code, which sets a tiered fine schedule based on the degree of the offense.8Pennsylvania General Assembly. Pennsylvania Code Title 34 Section 925 – Jurisdiction and Penalties General violations of Game Commission regulations that do not involve actually killing or possessing wildlife are summary offenses of the fifth degree, carrying fines of $100 to $200.3Pennsylvania General Assembly. Pennsylvania Code Title 34 – Chapter 21 Game or Wildlife Protection Violations involving unlawful taking or possession trigger higher penalties under Section 2307, reaching the upper summary offense tiers with fines of several hundred dollars or more.
Each animal counts as a separate offense. Five chipmunks killed without legal justification is five violations, each with its own fine. At the top of the summary offense scale, first-degree summary offenses carry fines of $1,000 to $1,500 with up to three months of possible jail time.8Pennsylvania General Assembly. Pennsylvania Code Title 34 Section 925 – Jurisdiction and Penalties For a single chipmunk taken without proper justification, realistic exposure sits in the low hundreds, but the per-animal stacking is where costs escalate.
When to Hire a Certified Operator
Pennsylvania requires anyone who traps nuisance wildlife on someone else’s property for a fee to hold a valid nuisance wildlife control operator certification from the Game Commission. If you hire someone, ask to see their current certification and check the expiration date. A legitimate operator should also carry liability insurance and provide references. Get a written contract that lists services and costs before signing anything, and confirm who is responsible for checking traps daily, weekends and holidays included.9Pennsylvania Game Commission. Nuisance Wildlife This is the cleanest option if you have active damage but do not want to handle trapping and disposal yourself.
