Bat Removal Laws in North Dakota: What Homeowners Need to Know
August 8, 2026
Finding a bat clinging to your curtains at midnight triggers an instinct to grab a broom or a can of pesticide. In North Dakota, that instinct can land you in legal trouble, because most bat species sharing your attic or chimney are protected under state and federal wildlife law. Understanding bat removal laws in North Dakota before you act protects both you and the animal, and it usually saves you money by avoiding fines or a botched exclusion job that lets bats back in within weeks.
This article walks through which bats are protected, when you can legally exclude them, what methods pass muster with regulators, and what happens if you get it wrong.
Are Bats a Protected Species in North Dakota
Most bats found in North Dakota homes are not fair game for a homeowner to trap and kill. Several bat species in North Dakota, including the little brown bat and the northern long eared bat, are federally protected, making it illegal to kill or harm them. The little brown bat (Myotis lucifugus) and the northern long-eared bat (Myotis septentrionalis) are the two species most commonly encountered in North Dakota structures, and both have faced steep population declines from white-nose syndrome, a fungal disease that has devastated hibernating bat colonies across the Midwest.
The North Dakota Game and Fish Department maintains a State Bat Management Plan that guides how the agency tracks bat populations, identifies roosting habitat, and works to align state regulations with bat conservation goals. Because bats fall under the state’s nongame wildlife framework, the same general protections that cover other nongame species in North Dakota apply to bats found in your home. For a broader look at how the state classifies and protects nongame animals, the nuisance wildlife laws in North Dakota guide breaks down which species carry protected status and which don’t.
Important Note: Protected status doesn’t mean bats can never be removed from a home. It means removal has to happen through approved exclusion methods, at the right time of year, rather than through killing or destroying a roost outright.
Is It Legal to Remove Bats From Your Home in North Dakota
Yes, but the method matters as much as the intent. You cannot legally kill, poison, or seal bats inside a structure where they will die trapped. Bats in a structure are protected, and removal requires specific exclusion techniques timed around maternity season to avoid trapping pups inside walls. That single fact shapes nearly every legal requirement that follows.
Trapping laws add another layer. It’s illegal in North Dakota to trap without a license, and once an animal is trapped, it must be removed and dealt with in the proper manner according to North Dakota law. This means a homeowner who catches a bat in a live trap still has to follow release or disposal rules rather than improvising. Licensed Wildlife Control Operators carry the permits and training to handle species and situations that fall outside the scope of what a private landowner can do unilaterally, which is why most North Dakota homeowners hire a professional rather than attempt a full exclusion themselves.
North Dakota’s wildlife statutes sit inside Title 20.1 of the North Dakota Century Code, which covers licensing, protected bird and animal regulations, and confiscation authority. If you’re weighing whether a broader wildlife issue on your property requires a permit or professional help, the wildlife removal laws in North Dakota overview explains how these statutes apply across species, not just bats. Local city ordinances can also apply, since local ordinances can add another layer of rules, particularly in cities and towns.
Bat Exclusion Season and Restricted Dates in North Dakota
Timing is the single biggest legal risk in bat removal. Exclude bats at the wrong time of year and you risk sealing flightless pups inside a wall cavity, where they die and create both an ethical problem and a lasting odor issue. Sealing the structure too soon can trap young bats in the attic or walls, creating odor, contamination, and a much bigger problem for the people inside the building.
In the Upper Midwest, maternity season generally falls in late spring through summer, though the exact timing depends on species, weather, and local conditions. A house in South Dakota may not line up exactly with one in Iowa or Minnesota, so there is no responsible one-size-fits-all calendar date for exclusion in this region, and North Dakota is no exception. Young bats begin leaving the roost in July and by mid-August should be fully fledged, which is the time of year when pest management professionals can legally pursue bat-proofing of structures.
Winter brings its own restriction. In late fall, some bats, especially the big brown bat, may return to a structure to hibernate through the winter, which is why some states prohibit or recommend against winter bat-proofing from November through March. Attempting to remove bats in the winter can be harmful since they may be in hibernation, and disturbing them could lead to their death.
| Season | General Legal Status for Exclusion | Why |
|---|---|---|
| Spring (before maternity season) | Generally allowed | Colony has not yet given birth; adults can safely relocate |
| Summer (maternity season) | Restricted | Flightless pups present; sealing entries risks trapping young bats |
| Late Summer to Early Fall | Preferred window | Pups are fledged and able to fly out on their own |
| Winter | Restricted or discouraged | Bats may be hibernating inside the structure |
Pro Tip: North Dakota doesn’t publish a single statewide bat exclusion proclamation the way it does for hunting seasons. Confirm current timing with the North Dakota Game and Fish Department or a licensed wildlife control operator before scheduling exclusion work.
Approved Bat Removal Methods in North Dakota
Legal bat removal in North Dakota relies on exclusion, not extermination. Bat exclusion usually first involves the use of a one-way bat door into the attic or other space to make sure that all bats are gone before any sealing is done. One-way doors, sometimes called bat valves, are installed on the points of entry that permit bats to exit the building but not re-enter, making this a humane and effective method of exclusion that often does not require handling bats by hand.
Once the colony has left, sealing gaps, vents, and rooflines prevents re-entry and future infestations. Installing bat houses outside the home provides bats with an alternative roosting spot and helps deter them from seeking shelter indoors, which offers a compromise that keeps bats on your property doing pest control work without letting them back into your walls.
- Approved methods: one-way exclusion doors, professional inspection and sealing, bat house installation, timed exclusion outside maternity and hibernation windows
- Prohibited methods: pesticide sprays, glue boards, sealing active entry points before bats have left, killing bats found roosting
Professional wildlife control companies specialize in bat removal and are trained to comply with state and federal laws, performing a thorough inspection of the home and installing exclusion devices properly. Because bats often roost in hard-to-reach spots like soffits and chimney flues, a professional inspection catches secondary entry points that a homeowner might miss during a DIY attempt.
Do You Need a Permit to Remove Bats in North Dakota
Homeowners generally don’t need a special state permit to exclude bats from their own house using approved, non-lethal methods during the legal window. The permit requirement shifts once trapping, relocation, or handling of protected wildlife enters the picture. Trapping any animal in North Dakota without a license is illegal, so if your exclusion plan involves live-trapping bats rather than letting them exit through a one-way door, you need a licensed operator or the appropriate trapping credentials.
Licensed Wildlife Control Operators carry the permits and training to handle species and situations that fall outside what a private landowner can do unilaterally, and this is especially true for large colonies, commercial buildings, or situations involving suspected rabies exposure. If you’re unsure whether your situation calls for a licensed professional, the nuisance wildlife laws in North Dakota resource outlines which scenarios cross that threshold. North Dakota’s broader hunting laws in North Dakota also touch on nongame licensing requirements that overlap with wildlife control permitting.
Pro Tip: Even when a permit isn’t strictly required for basic exclusion, hiring a licensed operator protects you from accidentally violating maternity-season or hibernation-season restrictions you might not know about.
What to Do If You Find a Bat Inside Your Home in North Dakota
A single bat flying through a living room is a different situation than a colony in the attic, and it calls for a calmer, more immediate response. Follow these steps if one bat gets inside your living space:
- Close the door to the room the bat is in, isolating it from the rest of the house.
- Open a window or exterior door and turn off the lights so the bat can find its way out on its own.
- If the bat lands, cover it with a coffee can or similar container, slide a piece of cardboard underneath, and carry it outside away from pets and children.
- Wash your hands and check for any bite or scratch marks, since bat teeth are small enough that a bite may go unnoticed.
- If anyone in the home may have had direct contact with the bat, especially while sleeping, contact a healthcare provider and local animal control, since rabies exposure protocols may apply.
If pets were in the room with the bat, check their vaccination records against North Dakota’s requirements, since exposure to a wild bat can trigger a mandatory quarantine or booster for unvaccinated animals. The pet vaccination laws in North Dakota page covers what’s required and what happens after a wildlife exposure incident. If a bat is found dead on your property rather than alive, disposal rules for wildlife carcasses are covered under the state’s roadkill laws in North Dakota, which address handling dead wildlife generally.
For an active colony rather than a single stray bat, skip the DIY approach entirely. Contacting a bat conservation group or a certified wildlife specialist is always recommended when you’re unsure of the best course of action, and colonies almost always require professional-grade exclusion equipment anyway.
Penalties for Illegal Bat Removal in North Dakota
North Dakota’s wildlife statutes give courts real teeth when it comes to enforcement. A conviction for a wildlife violation under Title 20.1 can result in the suspension of hunting, fishing, and trapping privileges for at least one year, two years for a second conviction, and three years for a third or subsequent conviction. Courts may suspend those privileges for up to three years in addition to other penalties, and certain serious offenses can trigger a suspension lasting up to the life of the defendant.
Because several North Dakota bat species carry federal protection as well, killing or harming a northern long-eared bat can also trigger enforcement under the federal Endangered Species Act, layered on top of any state penalty. The federal 4(d) rule for the northern long-eared bat illustrates how narrowly regulators define allowable activity near known maternity roosts, restricting even indirect disturbances like tree removal during pup season.

If you’re facing a specific enforcement action or need clarification on a bat removal situation, consult the North Dakota Game and Fish Department or a licensed attorney familiar with state wildlife law.
Beyond legal exposure, botched DIY removals often cost more in the long run. A colony sealed in during maternity season can mean weeks of decomposition odor, structural cleanup, and a repeat infestation once the surviving bats find a new gap to squeeze through. Comparing how neighboring states handle similar situations, such as the approach outlined in wildlife removal laws in North Carolina, shows that North Dakota’s timing-based restrictions are part of a broader national pattern rather than an unusual local rule.
Bat removal laws in North Dakota exist to balance a legitimate homeowner problem against a species already under pressure from disease and habitat loss. Sticking to the legal exclusion window, using approved one-way door methods, and calling a licensed operator for anything beyond a single stray bat keeps you on the right side of both state and federal law while giving the bats a fair shot at finding a new home.
