Bat Removal Laws in Louisiana: Protected Species Rules, Permits, and Legal Exclusion Windows
September 7, 2026
Finding a colony of bats in your attic in Louisiana feels like an emergency, but rushing to seal them in or spray them out can land you in violation of state wildlife law. Bat removal laws in Louisiana treat these animals as protected nongame wildlife, which means the timing, tools, and even who can legally do the work are all regulated. Before you plug a single gap or call an exterminator, it helps to understand exactly what the Louisiana Department of Wildlife and Fisheries (LDWF) allows.
This guide walks through the state’s protected species rules, the narrow window when exclusion is legal, and what happens if you get it wrong. Whether you’re dealing with a few stray bats in a New Orleans shotgun house or a colony in a rural barn, the same core legal framework applies statewide.

Are Bats a Protected Species in Louisiana
Bats are protected in Louisiana under Louisiana Wildlife and Fisheries Commission (LWFC) regulations, classified as nongame quadrupeds that cannot be hunted or trapped for sport or food. Because bats are also considered wildlife, they legally belong to the state and cannot be possessed without a permit. That legal status applies whether you’re dealing with a single bat that flew in through a chimney or an established colony roosting in a soffit.
The U.S. Fish and Wildlife Service lists four bat species as endangered in Louisiana: the gray bat, the Indiana bat, the northern long-eared bat, and the Rafinesque’s big-eared bat. These are the gray bat (Myotis grisescens), Indiana bat (Myotis sodalis), northern long-eared bat (Myotis septentrionalis), and Rafinesque’s big-eared bat (Corynorhinus rafinesquii). The Louisiana Natural Heritage Program also tracks rare, threatened, and endangered species statewide and lists two additional bat species as imperiled.
Louisiana’s more common attic-dwelling species aren’t federally endangered but still carry legal protection as nongame wildlife. The Brazilian free-tailed bat (Tadarida brasiliensis) and evening bat (Nycticeius humeralis) are the two species most likely to move into homes and outbuildings across the state. Both species are protected during certain times of the year, particularly during their breeding seasons.
| Bat Species | Louisiana Status |
|---|---|
| Gray bat | Federally endangered |
| Indiana bat | Federally endangered |
| Northern long-eared bat | Federally endangered |
| Rafinesque’s big-eared bat | Federally endangered |
| Brazilian free-tailed bat | Nongame, seasonally protected |
| Evening bat | Nongame, seasonally protected |
Anyone assessing a bat problem on Louisiana property should treat every species as protected by default. The hunting laws in Louisiana draw a clear line between regulated game species and nongame wildlife like bats, which never fall under recreational hunting seasons or bag limits.
Is It Legal to Remove Bats From Your Home in Louisiana
Removing bats from your home in Louisiana is legal, but killing them is not. It is not legal to kill bats in Louisiana unless you have special authorization from the LWFC, since bats are protected as nongame quadrupeds and wildlife. That distinction matters most for homeowners tempted to use pesticides, glue traps, or sealing methods that trap bats inside a structure.
Legal removal means live exclusion or relocation, done in a way that lets every bat leave the structure unharmed before entry points are sealed. Homeowners can perform basic exclusion work themselves, such as one-way netting over a known entry gap, but colony-level removal in a home’s attic or walls is best left to a permitted operator given the rabies exposure risk and the technical work of finding every gap.
Pro Tip: If you’re unsure whether you’re dealing with a single stray bat or an established colony, watch your roofline at dusk for 20–30 minutes. Multiple bats exiting the same gap signals a colony that needs professional exclusion.
The same protected-species framework shows up across Louisiana’s wildlife code more broadly. Rules governing duck hunting in Louisiana and bow hunting in Louisiana exist to regulate taking of game species, while bats and other nongame wildlife are governed under a separate nuisance-control structure entirely.
Bat Exclusion Season and Restricted Dates in Louisiana
Louisiana’s warm, humid climate means bat maternity season starts earlier and runs longer than in cooler states, and this is the single most important timing rule to understand. Excluding bats while flightless pups are still in the roost traps them inside, where they die and decompose, and it violates state wildlife protections.
Nearly all bats are protected and cannot be legally removed during the maternity season, typically May through August, because the young cannot yet fly. Because Louisiana hosts several species with overlapping but slightly different breeding calendars, the practical exclusion-restricted window stretches even wider than that general rule suggests.
| Species | Approximate Maternity Season |
|---|---|
| Evening bat | April 20 – July 15 |
| Brazilian (Mexican) free-tailed bat | May 20 – August 10 |
| Big brown bat | June 1 – August 15 |
| Little brown bat | June 1 – August 15 |
The little brown bat and big brown bat run their maternity season from June 1 through August 15, the Mexican free-tailed bat runs from May 20 through August 10, and the evening bat runs from April 20 through July 15. Given this overlap, most Louisiana wildlife professionals treat mid-April through mid-August as an off-limits window for any full colony exclusion.
LDWF advises against trapping in spring and early summer, the breeding season for most wildlife, because removing adults can orphan young that die inside an attic or under a house and cause additional problems as they decay. The safest legal windows fall in early spring, before maternity season begins, or in early fall after pups have fledged and before bats settle in for winter.
Key Insight: Some big brown bats overwinter inside structures rather than migrating, so late-fall and winter exclusion work still requires confirming the roost is empty before sealing entry points.
Approved Bat Removal Methods in Louisiana
Louisiana law is specific about how bats can be removed, and it rules out most of the shortcuts people assume are available for other nuisance animals. Under Louisiana Administrative Code Title 76, bats may be controlled by exclusion or by capture and relocation only, and bats shall not be controlled by any lethal methods. This single rule eliminates poison, fumigation, and lethal trapping as legal options for anyone, homeowner or professional.
One-way exclusion devices are the standard approved method. These allow bats to exit through their existing entry points at night to feed but prevent them from re-entering once they’ve left. Once a inspector confirms the roost is fully vacated, the remaining gaps are permanently sealed to prevent re-entry.
- Live exclusion: One-way valves or netting placed over confirmed entry points
- Capture and relocation: Hand capture of individual stray bats, released well away from the structure
- Exclusion timing checks: Confirming the roost is empty (often via dusk observation) before permanent sealing
- Entry point sealing: Caulk, foam, mesh, or flashing applied only after all bats have left
LDWF recommends that nuisance wildlife control operators working with bats complete the Bat Conservation International professional excluders’ course. That training standard reflects how technical proper exclusion work actually is, since even a small missed gap can let bats back into a structure.
Common Mistake: Sealing every visible gap at once, rather than leaving the primary exit open until the colony has fully vacated, is one of the most common reasons homeowners end up with bats trapped inside walls.
Anyone comparing methods approved in other states will find similar rules. Wildlife removal laws in North Carolina and wildlife removal laws in Arizona both restrict bat control to nonlethal exclusion methods, mirroring Louisiana’s approach and reflecting a national pattern driven largely by federal bat conservation concerns.
Do You Need a Permit to Remove Bats in Louisiana
Whether you need a permit depends on who’s doing the work. LDWF does not remove nuisance wildlife itself; instead, it permits individuals called Nuisance Wildlife Control Operators to provide these services for a fee, and there are more than 100 permitted operators located across the state. Anyone charging money to remove bats from a Louisiana property must hold that permit.
Becoming a permitted operator isn’t casual paperwork. Applicants must possess a valid Louisiana trapping license and basic hunting license, be at least 18 years old, and achieve a minimum score of 80 percent on the LDWF examination covering wildlife biology, nuisance control methods, and relevant laws. NWCO permits are issued on a calendar-year basis and must be renewed annually.
Homeowners handling a problem on their own property face a lighter standard. Louisiana Administrative Code Title 76 outlines the rules for live trapping and releasing wildlife without a permit, which generally covers simple, self-performed exclusion work. That said, given the rabies risk and the technical difficulty of confirming a roost is fully vacated, most homeowners are better served hiring a licensed operator rather than attempting colony-level exclusion themselves.
If lethal control is ever genuinely necessary, that requires separate state authorization entirely. The only exception to Louisiana’s no-kill rule for bats is a valid depredation permit issued by the LWFC. These are rarely granted and reserved for exceptional circumstances, not routine nuisance calls.
What to Do If You Find a Bat Inside Your Home in Louisiana
A single bat flying loose in a living room calls for a different response than a colony in the attic. Start by closing off the room, turning off ceiling fans, and giving the bat a clear path to an open window or door, ideally after dark when it’s most likely to fly out on its own.
Rabies exposure is the primary safety concern with any direct contact. Certain mammals, including bats and skunks, may be infected with rabies and can transmit it to humans, and rabies is fatal to humans if not treated before symptoms develop. Bats account for roughly one-third of reported rabies infections annually, which is why any contact with a bat, or finding one in a room with a sleeping person or unattended child, warrants medical attention rather than a wait-and-see approach.
Important Note: If you or a pet may have had physical contact with a bat, do not release it. Contact the state public health veterinarian and your doctor even if the animal has already been released and can’t be recaptured.
For colonies rather than lone bats, don’t attempt DIY removal from an occupied attic, especially during maternity season. Contact an LDWF-permitted Nuisance Wildlife Control Operator, who can confirm the species, assess entry points, and schedule exclusion for a legally approved window. This is also the point where issues can overlap with other property concerns; if a colony has settled somewhere shared with a neighbor’s property line, the same general nuisance-wildlife principles that apply to a neighbor’s cat wandering onto your yard in Louisiana come into play regarding who’s responsible for addressing the animal.
Penalties for Illegal Bat Removal in Louisiana
Because bats are protected nongame wildlife, killing one without a depredation permit is a violation of Louisiana Wildlife and Fisheries Commission regulations, and enforcement falls to LDWF wildlife enforcement agents. Hunting or otherwise unlawfully killing bats in Louisiana can result in fines or penalties, separate from any civil liability tied to property damage from mishandled removal attempts.
Permitted operators face their own compliance obligations, and cutting corners there carries consequences too. Any NWCO who fails to submit a required report by the deadline, or who submits a false or materially incomplete report, is issued a citation for violation of Louisiana Wildlife and Fisheries Commission rules and regulations. Operators must also keep copies of all Nuisance Wildlife Complaint Forms for three years, and failing to maintain those records can factor into a citation as well.
Beyond the regulatory fines, illegal removal during maternity season creates a practical mess that outlasts any penalty. Removing bats during the maternity season without a special permit can result in prosecution and heavy fines, and orphaned pups trapped inside walls decompose, creating odor and sanitation problems that are far more expensive to fix than a properly timed exclusion would have been. The safest and cheapest path, in every sense, is scheduling exclusion work within the legal window and through a permitted operator.
Louisiana’s approach fits a pattern seen elsewhere in the country. States like California and Minnesota apply similarly strict seasonal and method restrictions on bat removal, underscoring how consistently U.S. states treat bat conservation as a priority even in routine nuisance-wildlife cases.
