Bat Removal Laws in Indiana: Protected Species, Permits, and Exclusion Season Rules
August 28, 2026
If you seal up a bat colony in your attic on the wrong week, you could be violating both state and federal law without ever touching a firearm or a trap. Bat removal laws in Indiana are shaped almost entirely around timing, because the state is home to two federally endangered bat species that raise flightless pups inside human structures every summer. Understanding when and how you can legally exclude bats from your home protects both you and the animals living in your walls.
This guide walks through what Indiana law actually allows, from protected species status to permit requirements and the penalties for getting it wrong. You will also find practical steps for handling a bat that has already found its way into your living space.
Are Bats a Protected Species in Indiana
Not every bat flying through your attic carries the same legal weight. The Indiana bat (Myotis sodalis) is a federally endangered species, and Indiana’s own name is attached to it because the species was first described from specimens found in a cave in the state. The Indiana bat is federally endangered, and any control work that might affect the species requires a Section 10 Incidental Take Permit from the U.S. Fish & Wildlife Service, a rule that applies to exclusion work in habitats where Indiana bats may be present in summer or winter.
The Northern long-eared bat (Myotis septentrionalis) shares similarly strict protections. This species is also federally listed as endangered, with restrictions similar to those covering the Indiana bat. Both species appear on Indiana’s endangered species list alongside other wildlife such as the alligator snapping turtle, eastern massasauga rattlesnake, and timber rattlesnake.
Most of the bats homeowners actually encounter in attics are not these two rare species. The two main bat species found in Indiana homes are the little brown bat and the big brown bat, commonly known by the scientific names Myotis lucifugus and Eptesicus fuscus. Even though these species are not federally endangered, Indiana still regulates how they can be handled, since it’s often impossible to visually confirm a species while bats are actively roosting. For a broader look at how the state treats nuisance animals beyond bats, the wildlife removal laws in Indiana apply a similar precautionary framework across many species.
Important Note: Because little brown bats and big brown bats look similar to protected species without close inspection, Indiana’s exclusion rules apply broadly to all bat colonies in structures, not just confirmed endangered ones.
Is It Legal to Remove Bats From Your Home in Indiana
Yes, but the legality depends heavily on method, timing, and quantity. Indiana law gives property owners the right to protect their property from wildlife damage, and generally, without any special permit, property owners may exclude wildlife from structures, though bat exclusion carries seasonal restrictions. This means you can legally remove bats from your home, just not whenever you want or however you want.
Indiana DNR also carves out a narrow allowance for immediate safety concerns. An individual person may take up to five individual bats within a 24-hour period from a dwelling if the bat constitutes a demonstrable but nonimmediate threat to human safety, without a permit. That provision covers a bat that flew into your bedroom, not a colony living in your soffit.
Where things get more complicated is scale. A handful of stray bats inside living space is treated differently than an established colony roosting in an attic or wall void, which is why exclusion (not trapping or killing) is the only legal path for colony-level removal. This distinction mirrors how many states approach the issue; California, for instance, applies its own version of this rule under its wildlife removal laws in California, which also restrict bat handling due to species protections.
Bat Exclusion Season and Restricted Dates in Indiana
Timing is the single most important legal detail in Indiana bat removal. Bat exclusion is prohibited from May 15 through August 15 to protect the federally endangered Indiana bat and other species during maternity season, when flightless pups are present. Sealing entry points during this window traps pups inside a structure, where they die.
Indiana DNR frames the maternity period slightly differently in its own materials. Maternity season is usually between mid-June and early August, and pups depend on their mothers for anywhere between 25 and 37 days. Exact timing varies with local weather and the condition of female bats, and pups may be born earlier in southern Indiana and a few weeks later in the northern part of the state.
Important Note: You may see slightly different exclusion windows cited by different wildlife control companies (some use June 1 through August 15). The variation reflects real regional differences in maternity timing across Indiana, so when in doubt, the more conservative window protects you legally.
Winter presents its own restriction, just for a different reason. Bats may be hibernating inside a structure during colder months, and sealing entry points during hibernation can trap bats, causing them to die inside walls. DNR’s own guidance reflects this concern directly.
| Season | Exclusion Status | Reason |
|---|---|---|
| Late August through April | Legal exclusion window | Recommended timing for exclusion work outside maternity restrictions |
| May 15 – August 15 | Exclusion prohibited | Maternity season; flightless pups present in the colony |
| Deep winter (hibernation) | Exclusion discouraged | Bats hibernating in structure risk dying if sealed inside |
Indiana isn’t alone in tying bat removal to a calendar. States like Minnesota apply comparable maternity-season restrictions under their own wildlife removal laws in Minnesota, since most northern bat species share similar breeding cycles.
Approved Bat Removal Methods in Indiana
Indiana law is specific about which removal techniques are legal and which are not. Only one method is broadly approved for colony removal, and it does not involve trapping or killing the animals.
- Exclusion (legal): One-way devices are installed over entry points so bats can exit but not return; once all bats have departed, entry points are permanently sealed.
- Individual capture (limited legal use): Individual bats found inside living spaces can be captured and released, but trapping an entire colony is not permitted.
- Poisoning or fumigation (illegal): Using pesticides or poisons on bats is a federal violation and is never appropriate.
The exclusion process itself follows a predictable sequence once the legal window opens. Legal bat control work includes installing one-way exclusion devices at active entry points, allowing the colony time to fully vacate, permanently sealing all entry points once they’re gone, and cleaning and treating any guano contamination left behind.
Pro Tip: Scheduling an inspection before exclusion season opens lets a licensed operator map entry points and prepare equipment in advance, so work can begin the moment the legal window opens rather than starting from scratch.
Cost is worth planning for, since delays tend to make the job more expensive. Bat exclusion typically costs $500 to $2,500 depending on colony size, number of entry points, and building complexity, with a small colony at one or two entry points on the lower end and a large colony in a complex structure exceeding $2,500. States with drier climates, such as Arizona, tend to see different cost drivers for exclusion work under their own wildlife removal laws in Arizona, largely due to different bat species and roost types.
Do You Need a Permit to Remove Bats in Indiana
Whether you need a permit depends on who is doing the work and what species may be involved. A homeowner dealing with a stray bat or two generally does not need a permit, since up to five individual bats may be taken within 24 hours from a dwelling without a permit when they pose a demonstrable but nonimmediate threat. Colony-level exclusion work is a different matter.
Anyone performing nuisance wildlife control for pay in Indiana needs formal credentials. Passing a DNR-administered exam covering Indiana wildlife law and approved methods is required, and performing nuisance wildlife control for compensation without a registration is a Class C infraction for a first offense that escalates with subsequent violations. Beyond the general registration, there is an additional layer of paperwork for protected species.
A Nuisance Wild Animal Control Permit is issued to control a nuisance wild animal protected by state law, and anyone providing this service to the public for a fee must pass a test and pay a $25 permit fee. If Indiana bats or Northern long-eared bats are known or suspected to be present, an extra federal step applies. Any control work that might affect Indiana bats requires a Section 10 Incidental Take Permit from the U.S. Fish & Wildlife Service, which applies to exclusion work in habitats where the species may be present during summer or winter.
The regulatory structure sits across two overlapping authorities. Indiana’s approach to nuisance wildlife control is governed primarily by IC 14-22-38 covering nuisance wildlife control operators and 310 IAC 3.1, the DNR’s administrative rules covering wildlife, while the U.S. Fish & Wildlife Service governs federally protected species separately. If you’re unsure which permit applies to your situation, the DNR Permit Coordinator can be reached at 317-232-4102 or wildlifepermits@dnr.IN.gov for guidance before you act. Other states structure their permitting similarly; North Carolina, for example, splits authority between state wildlife agencies and federal regulators under its own wildlife removal laws in North Carolina.
What to Do If You Find a Bat Inside Your Home in Indiana
A single bat flying through a living room calls for a calm, methodical response rather than a call to an exterminator. Close the doors to the room, turn off ceiling fans, and give the bat a chance to exit through an open window or door on its own, since bats often find their way back out within a few minutes.
If the bat lands and you need to capture it, cover it with a coffee can or similar container, slide a piece of cardboard underneath, and carry it outside before releasing it away from people and pets. Never handle a bat with bare hands, since bites can be small enough to go unnoticed and bats can carry rabies.
Winter finds require a different response than summer finds. If you find bats in your home during the winter, contact a wildlife rehabilitator or a wildlife control operator to help you safely find a solution, and if bats are found within the living spaces of your home during winter, they need to be removed immediately. Releasing a bat outside in freezing temperatures is not a safe option, since a bat forced outside during winter will likely die of exposure or starvation.
Common Mistake: Releasing a hibernating bat outdoors during winter feels humane but is often a death sentence for the animal, since its food source (flying insects) isn’t available and exposure sets in quickly.
DNR also asks residents to help track bat activity across the state. If the animal encountered is a bat or a weasel, reporting it helps DNR biologists monitor species distributions across Indiana, so photographing the bat before release (from a safe distance) can support conservation tracking. Wisconsin runs a comparable citizen-reporting approach for bat sightings under its wildlife removal laws in Wisconsin.
Penalties for Illegal Bat Removal in Indiana
Getting the timing or method wrong on bat removal carries real legal consequences at both the state and federal level. Under Indiana’s general fish and wildlife statute, a person who violates the article covering fish and wildlife commits a Class C misdemeanor, except as otherwise provided. Operating a paid nuisance wildlife control business without registration triggers a separate, lower-level violation that still escalates with repeat offenses, as noted earlier under permit requirements.
Federal exposure is where penalties become far more serious, especially involving the Indiana bat or Northern long-eared bat. Civil violations of the Endangered Species Act can cost up to $25,000 per bat, while criminal charges may bring up to a year in prison and fines reaching $100,000 for individuals. Even accidental harm, such as sealing a roost during maternity season, can count as a violation, which is exactly why the May 15 through August 15 restriction matters so much in practice.
State-level consequences extend beyond fines. License consequences can follow a conviction, misdemeanor penalties can result in fines, imprisonment, or both, and repeated violations may lead to hunting license suspension or revocation. Indiana is a member of the Wildlife Violator Compact, meaning a license suspension in Indiana can be recognized and enforced in other member states. These same enforcement principles show up across Indiana’s broader wildlife statutes, including its animal cruelty laws, which reflect a similarly layered approach to state and federal accountability.
The most practical safeguard against any of this is a phone call before action. Contacting the Indiana DNR Division of Fish and Wildlife before taking action costs far less than the price of a misdemeanor conviction, and the same logic applies to hiring a properly registered wildlife control operator rather than attempting colony removal yourself.
Indiana’s bat removal rules boil down to a fairly simple principle once you understand the moving parts: exclusion is legal, but only outside the May 15 to August 15 maternity window, only through one-way devices rather than trapping or poison, and only with the right registration if you’re paying someone or dealing with a federally protected species. If bats are actively roosting in your home right now, the safest move is scheduling an inspection so you’re ready to act the moment the legal window opens, rather than risking a violation to solve the problem sooner.
