Yes , nearly all North American bat species are protected by law. Bats play a critical role in insect control, pollination, and seed dispersal.
Because of their ecological importance and population declines from white-nose syndrome, most bat species are protected at the state and federal level. Attempting to kill, trap, or permanently exclude bats without following legal guidelines can result in significant fines and legal liability.
This guide covers bat protection laws by state and how to comply.
Key Takeaways
- Federal protection: Several bat species are protected under the Endangered Species Act. Killing or harming them carries severe penalties.
- State protection: Most states classify bats as protected non-game wildlife. Exclusion requires permits or specific methods.
- Maternity season restrictions: Most states prohibit exclusion during May-August when flightless pups are present.
- Legal exclusion methods: One-way exclusion valves are legal in most states. Killing, trapping, or poisoning bats is illegal.
- Penalties: Fines for illegal bat exclusion range from $500 to $25,000 per violation depending on species and jurisdiction.
Federal Bat Protections
Under the federal Endangered Species Act (ESA), several bat species are listed as endangered or threatened. These species and their roosts are protected from harm, harassment, and habitat destruction:
- Indiana bat (Myotis sodalis) , Federally Endangered. Found in the eastern and midwestern US. Protected year-round.
- Northern long-eared bat (Myotis septentrionalis) , Federally Threatened. WNS-affected populations across eastern US.
- Gray bat (Myotis grisescens) , Federally Endangered. Found in limestone cave regions of the southeastern US.
- Lesser long-nosed bat (Leptonycteris yerbabuenae) , Federally Endangered. Found in Arizona, New Mexico, and Texas.
- Florida bonneted bat (Eumops floridanus) , Federally Endangered. Found only in southern Florida.
- Tricolored bat (Perimyotis subflavus) , Proposed for ESA listing. Over 90% population decline from WNS.
Legal Warning
If your property is within the known range of an ESA-listed bat species, you may need to coordinate with the US Fish and Wildlife Service before performing exclusion. A bat survey by a qualified biologist may be required. Penalties for harming ESA-listed bats can reach $25,000 per violation.
State-Level Bat Protections
Most states classify bats as non-game wildlife, which means they cannot be killed, trapped, or possessed without a permit. The specific regulations vary by state. Here is a general overview:
| Region | Typical Protection Level | Exclusion Rules |
|---|---|---|
| Northeast | High , many WNS-affected states | Permit required for large colonies. Maternity season ban May-Aug. |
| Southeast | Moderate-High , several ESA species present | Legal with one-way valves. Maternity season recommended ban. |
| Midwest | Moderate , varies by state | Generally legal. Check for Indiana bat range restrictions. |
| West | Moderate , many species still common | Legal exclusion. Some states require permits for any bat handling. |
| Southwest | Moderate-High , ESA nectar bats present | Seasonal restrictions for nectar bat species. Check local laws. |
Important
State laws change frequently, especially as WNS spreads and new species are listed. Always verify current regulations with your state wildlife agency before performing bat exclusion. This guide was last updated in 2026 and may not reflect recent changes.
Bat Maternity Season Restrictions
The most common legal restriction for bat exclusion is the prohibition on exclusion during maternity season. Bat maternity season typically runs from May 1 through August 15 in most states, though the exact dates vary by region and species. During this period, bat pups are unable to fly.
Sealing bats inside during maternity season traps pups with their mothers, resulting in death by starvation, odor problems, and legal liability.
If you discover a bat colony during maternity season, most states require you to wait until the pups can fly before excluding. Call a licensed wildlife exclusion professional who can assess whether pups are present.

Legal Exclusion Methods
Across all states, the following methods are legal for bat exclusion:
- One-way exclusion valves , Let bats exit but prevent re-entry. Legal in all states.
- Exclusion netting , Temporary netting that allows bats to exit. Must be removed after exclusion period.
- Sealing entry points , After bats have left, permanent sealing with appropriate materials.
- Installing bat houses , Providing alternative roosts is encouraged and often recommended by wildlife agencies.
The following methods are ILLEGAL for bat control in most states:
- Killing or poisoning bats , Illegal in nearly all states. Bat poisons do not exist because bats are protected.
- Trapping and relocating , Often illegal because relocated bats rarely survive and may spread WNS.
- Sealing bats inside , Illegal in multiple states. Constitutes animal cruelty.
- Using glue traps or sticky boards , Illegal in most states. Bats die slowly on glue traps.
