Chipmunks are protected in Pennsylvania because of how the state’s wildlife code is structured. Any wild mammal that isn’t specifically classified as a game animal or furbearer automatically receives “protected” status under Pennsylvania law. Chipmunks fall into neither hunting category, so they land in this default protected class. It’s less about chipmunks being rare or endangered and more about a legal framework designed to prevent unregulated killing of wildlife.
What “Protected” Actually Means in PA Law
Pennsylvania’s wildlife classification system, found in Title 58 of the state code, sorts wild mammals into three main buckets: game animals (like deer and rabbits), furbearers (like foxes and muskrats), and protected mammals. That third category is a catch-all. The regulation states that wild mammals not defined as furbearers or game animals “shall be classified as protected mammals to be taken only under the act.” In plain terms, you can’t hunt, trap, or kill chipmunks recreationally the way you could a squirrel during squirrel season.
This doesn’t mean chipmunks have some special conservation status or that their populations are struggling. Eastern chipmunks are common throughout Pennsylvania’s forests, suburbs, and parks. The protection simply means the state hasn’t opened a regulated season for them, and general wildlife laws apply. Many other small mammals you’d recognize, like shrews and voles, fall into the same protected category for the same reason.
Why Chipmunks Aren’t Classified as Game or Furbearers
Game animals in Pennsylvania are species with established hunting traditions and populations large enough to support managed harvest seasons. Furbearers are species trapped primarily for their pelts. Chipmunks don’t fit either profile. They’re too small to be a meaningful game species, and their fur has no commercial value. There’s simply no practical reason to create a regulated hunting or trapping season for them, so the default protection stays in place.
This is a common approach across many states. Rather than listing every species that deserves protection, the law protects everything by default and then carves out exceptions for species that can sustain regulated harvest. It’s a precautionary structure that keeps wildlife management from becoming a free-for-all.
Their Role in Pennsylvania’s Ecosystem
Chipmunks play a bigger ecological role than their size suggests. They’re omnivores that eat seeds, nuts, fruits, insects, snails, and occasionally bird eggs or small reptiles. Their diet of acorns, maple seeds, and berries makes them active seed dispersers throughout Pennsylvania’s hardwood forests. When chipmunks cache food underground for winter and forget about some of it, those buried seeds can germinate into new trees and plants.
They’re also an important food source for hawks, owls, foxes, weasels, and snakes. Their burrow systems, which can be surprisingly extensive, provide shelter for other small animals after chipmunks abandon them. Weasels, for example, rarely dig their own nests and prefer to take over chipmunk or mouse burrows. Removing chipmunks from an area can ripple through the local food web in ways that aren’t immediately obvious.
What You Can Do if Chipmunks Are Causing Damage
Protected status doesn’t leave property owners without options. Pennsylvania law gives landowners the right to protect their property from wildlife damage. With certain exceptions (deer, bear, elk, beaver, bobcat, fisher, wild turkey, migratory birds, and threatened or endangered species require special permits), property owners can take action when personal property other than agricultural crops is being destroyed, or when a sick animal poses a threat to humans or pets. Chipmunks are not on the exception list, so standard nuisance wildlife rules apply.
Only the property owner or the person in charge of the property may capture or kill nuisance wildlife. The Pennsylvania Game Commission recommends contacting your regional office before trapping nuisance chipmunks.
Penn State Extension recommends starting with exclusion. Sealing entry points with caulking or quarter-inch hardware cloth keeps chipmunks out of buildings. The same mesh can protect flower beds, bulbs, and seeds when buried under a layer of soil, extending at least one foot past each edge of the planting.
If exclusion isn’t enough, live-catch wire mesh traps or standard rat snap traps are both options. Peanut butter, sunflower seeds, and raisins all work as bait. A useful trick is to “prebait” for two to three days by wiring the trap doors open so the chipmunk gets comfortable feeding inside before you actually set it. Once you catch a chipmunk in a live trap, you can transport it several miles from your property and release it in an area where it won’t become someone else’s problem, or humanely euthanize it. Avoid handling trapped chipmunks directly.
Landscaping choices matter too. Ground cover, shrubs, and woodpiles that connect wooded areas to your home’s foundation create protected highways for chipmunks. Breaking up that continuous cover makes your property less inviting and makes it easier to spot burrow entrances near your foundation before they become a structural issue.
