Bat Removal Laws in Alaska: What Homeowners Need to Know Before Acting

Most people picture bats in warm caves or old barns down south, not in the spruce forests of Anchorage or the rainforests of Southeast Alaska. Yet the state has seven resident bat species, and every fall, homeowners across Alaska discover a colony roosting in their attic. Understanding bat removal laws in Alaska before you seal a single crack matters, because state code treats bats as protected wildlife, not household pests you can handle however you like.

This guide walks through what Alaska statute actually says about bats in your home, when you’re allowed to exclude them, what methods are approved, and what happens if you get it wrong.

Are Bats a Protected Species in Alaska

Alaska is home to seven bat species, and the one you’re most likely to find in a building is the little brown bat, scientifically known as Myotis lucifugus. Alaska has seven different species, and the little brown bat is the most common and widespread bat in the state, found from Southeast to as far north as Kotzebue. The state’s other bats are found only in Southeast Alaska, including California myotis, long-legged myotis, Yuma myotis, the hoary bat, the silver-haired bat, and the western long-eared bat. The silver-haired bat (Lasionycteris noctivagans) and western long-eared bat (Myotis evotis) are both far less common than the little brown bat and are documented almost exclusively along the state’s southeastern panhandle.

You might wonder whether any of these species carry federal Endangered Species Act protection. They don’t, at least not yet. Bats are not considered endangered species in Alaska, and according to the Alaska Department of Fish and Game, there are no state or federal laws that specifically protect bats as endangered or threatened species in the state. That doesn’t mean they’re unprotected, though. The little brown bat is managed as an unclassified game species in Alaska, meaning it cannot legally be harassed or killed except under the terms of a wildlife nuisance permit issued by the Alaska Department of Fish and Game.

Unclassified game status puts bats in a different category than deer, moose, or other animals covered under Alaska’s hunting laws in Alaska. Little brown bats are managed as “unclassified game” in Alaska and there are no seasons or bag limits. That regulatory gap is exactly why homeowners need to understand exclusion rules rather than assume bats can simply be trapped and disposed of like a nuisance rodent.

Key Insight: Alaska doesn’t list bats as endangered, but state code still makes it illegal to kill, trap, or possess one without a permit. “Not endangered” does not mean “unprotected.”

Is It Legal to Remove Bats From Your Home in Alaska

Yes, you can legally remove bats from your Alaska home, but how you do it matters a great deal. It is not legal to kill bats in Alaska, and the state’s administrative code prohibits killing or injuring a bat unless it’s necessary to protect human life or property. Exclusion, the process of sealing entry points so bats leave and can’t return, is the legal path forward for nearly every homeowner.

Bats are protected in Alaska under the Alaska Administrative Code, Title 5, Chapter 92, Section 420, which states that a person may not take, possess, transport, sell, offer to sell, purchase, or offer to purchase a bat unless authorized by permit issued by the department. That single regulation covers most of what you need to know: you can make your home unwelcoming to bats, but you can’t capture, kill, or relocate them on your own without running afoul of state law.

Exclusion is the only effective solution for permanently removing bats from buildings, according to the Alaska Department of Fish and Game. The department also notes why professional help is often worth the cost: hiring a licensed professional keeps you from accidentally straying outside of Alaska statutes, since professionals are licensed and experienced in exclusion work. This is a meaningfully different legal landscape than states like California, where wildlife removal laws in California apply a separate set of licensing and depredation permit rules to bat exclusion work.

Bat Exclusion Season and Restricted Dates in Alaska

Timing is the single biggest legal and practical factor in bat removal, and Alaska’s short summers make the exclusion window narrower than in most states. Bats raise their young in maternity roosts during the summer, and sealing a building while flightless pups are still inside can trap and kill them, which creates both an ethical problem and a legal one under the state’s anti-killing provisions.

• June and July: Juvenile bats may be present in roosts during these birthing months, and under certain conditions, removal is restricted because of federal protection laws when juveniles are present.
• Late September to early October: This is when exclusion should happen in Alaska, once the pups are old enough to leave the roost and forage alongside the adult females.
• October: Wildlife officials recommend waiting until fall when most or all bats have left for hibernation sites, noting it is safe to exclude bats from buildings in October.

Pro Tip: If you find bats in your attic in June or July, wait. Sealing entry points during maternity season is the single most common way homeowners accidentally violate Alaska’s anti-killing provisions.

States with milder climates and longer bat activity seasons, such as those covered in wildlife removal laws in Minnesota, sometimes allow exclusion work slightly earlier in the fall. Alaska’s compressed summer means the window for safe, legal exclusion is genuinely tighter, so marking your calendar for late September matters more here than almost anywhere else in the country.

Approved Bat Removal Methods in Alaska

Alaska law doesn’t leave much room for improvisation. Poisons, glue traps, and sealing occupied roosts are all off the table, both because they tend to kill bats and because killing bats without a permit is illegal under state code. The approved method is exclusion, carried out in a specific sequence.

1. Inspect the building. Examine the structure for potential entrances, checking common entrance spots like chimneys, vents, soffits, joists, and corners.
2. Install one-way exclusion devices. The most common solution for safely removing bats from a home or business in Alaska is one-way tubes set at each entry point, so bats can leave to feed in the evening but can’t get back in.
3. Wait it out. Leave exclusion devices in place for a minimum of seven days to make sure all the bats have left.
4. Seal the entrances. Once you’ve confirmed the bats are gone, you can remove the exclusion devices and permanently seal the entrances.
5. Offer an alternative roost. Some conservation-minded exclusion companies install cedar bat boxes on the property before starting the eviction process, giving displaced bats somewhere else to go.

Compare that to how wildlife removal laws in Arizona handle desert-dwelling bat species, where colony size and cave-roosting behavior often call for different exclusion timing. Alaska’s approach centers on the same core principle found across most state bat laws: exclude, don’t exterminate.

Do You Need a Permit to Remove Bats in Alaska

For a straightforward do-it-yourself or professional exclusion where no bats are trapped, harmed, or killed, you generally don’t need a permit. The moment removal shifts toward trapping, killing, or otherwise “taking” a bat, state law requires authorization. You cannot trap a bat in Alaska without a permit from the Alaska Department of Fish and Game. It’s also illegal in Alaska to trap any wildlife without a license, full stop.

Professionals who need to take nuisance wildlife, including bats causing property damage, typically operate under a wild animal control license issued by the state. To qualify, an applicant must be at least 18 years old, must have completed a hunter education course or provided proof of equivalent firearms safety training, must not have been convicted of a fish or game violation in the preceding five years, and must demonstrate experience or a written methodology for nuisance wildlife control. Even licensed operators can only take nuisance wildlife when the animal has invaded a dwelling, is causing property damage, or poses an immediate threat, and only after all other practicable means of protecting the property have been exhausted.

This licensing framework overlaps with Alaska’s broader nuisance wildlife laws, which apply the same permit-based logic to bears, foxes, and other animals that end up on private property. States like Illinois take a comparable stance; if you’re comparing frameworks, wildlife removal laws in Illinois also require licensing before any wildlife can be trapped or removed from a structure. Alaska doesn’t operate a state-issued “wildlife control operator” license in quite the same way some other states do, but professionals in this space must still hold valid state trapping licenses and comply with ADF&G permit conditions.

What to Do If You Find a Bat Inside Your Home in Alaska

A single bat flying through your living room is a different situation than a roosting colony, and it calls for a calmer, more immediate response. Close the door to the room the bat is in, open a window, and give it a quiet path outside. Do not swat at it, and never handle it with bare hands.

Rabies is the main reason for caution, though the actual risk in Alaska is lower than most people assume. Bats can carry rabies, but fewer than 1% of bats tested in the US have been positive, and in more than 50 years of testing in Alaska, only six cases have ever been detected, all in Southeast Alaska, with no cases ever recorded north of that region and none ever transmitted to a human. Most rabies transmission cases nationally happen because someone picked up a sick or dead bat with bare hands.

Important Note: This article provides general legal and safety information, not medical advice. If you or a pet is bitten or scratched by a bat, contact a healthcare provider or veterinarian immediately, since rabies exposure requires prompt evaluation regardless of how rare confirmed cases are in Alaska.

If you have pets that roam near an active roost, keeping their rabies vaccinations current is one of the simplest safeguards available; Alaska’s pet vaccination laws cover what’s required for dogs and cats statewide. Because of the health risks associated with bats, a professional should handle decontamination, since specialized filtration equipment and precautions are needed to safely remove bat guano without negative health effects. Baby bats are sometimes left behind after a removal service is completed or after straying from their roost, and you should not attempt to pick one up yourself. Call a licensed wildlife removal service or Alaska Wildlife Rescue instead. Homeowners in wildlife removal laws in Wisconsin face a nearly identical protocol for stray bats, which suggests this “isolate, don’t handle, call a professional” approach is close to a national standard.

Penalties for Illegal Bat Removal in Alaska

Alaska takes wildlife code seriously, and bat-related violations fall under the same enforcement framework as other fish and game offenses. Under Alaska Statute AS 16.05.925, most fish and game violations are classified as class A misdemeanors, which can carry fines up to $10,000 and up to one year in jail. That means killing a bat outside the narrow self-defense exception, trapping one without a license, or possessing a bat without a permit can all expose you to serious criminal liability, not just a warning citation.

Unlawfully killing, possessing, or transporting wildlife can result in criminal charges, significant fines, loss of hunting and trapping privileges, and imprisonment depending on the severity of the offense. Courts may also order forfeiture of equipment used in the violation, including traps and other tools. While most homeowner bat cases won’t approach the top end of these penalties, the exposure is real, which is part of why the Alaska Department of Fish and Game consistently steers residents toward exclusion rather than DIY trapping or extermination.

Violation	Governing Law	Potential Penalty
Killing a bat without justification	5 AAC 92.420; AS 16.05.925	Class A misdemeanor, up to $10,000 fine, up to 1 year jail
Trapping a bat without a license	AS 16.05.340; 5 AAC 92.420	Class A misdemeanor
Possessing or transporting a bat without a permit	5 AAC 92.420	Class A misdemeanor

For context, states like Virginia and North Carolina apply comparable misdemeanor frameworks to unauthorized bat handling; if you split time between states, it’s worth reviewing wildlife removal laws in Virginia and wildlife removal laws in North Carolina before assuming the rules carry over.

The bottom line for anyone dealing with bats in an Alaska home: exclusion in early fall, performed carefully and without killing or trapping the animals, keeps you well within the law. Bats deliver real pest-control value by eating mosquitoes and other insects all summer, and the state’s rules are built to let homeowners solve a real nuisance without wiping out a slow-reproducing, ecologically useful species in the process.
