Bat Removal Laws in Vermont: When and How Homeowners Can Legally Remove Bats
August 15, 2026
Finding a colony of bats in your attic in Vermont means navigating more than pest control logistics. The little brown bat, one of the state’s most common house-dwelling species, is listed as endangered under Vermont law, and that status controls when, how, and by whom bats can be removed from a structure. Bat removal laws in Vermont are stricter than most homeowners expect, with seasonal restrictions, approved exclusion methods, and permit rules that apply even to a single bat trapped in a bedroom.
This breakdown walks through what Vermont’s wildlife statutes and Fish & Wildlife Department guidance actually require, from protected-species status to the penalties for getting exclusion wrong.
Pro Tip: Before attempting any bat exclusion in Vermont, check the calendar first. Timing mistakes are the most common way well-meaning homeowners end up in violation of state wildlife law.
Are Bats a Protected Species in Vermont
Of Vermont’s nine species of bats, two – the little brown bat and the big brown bat (Eptesicus fuscus) – commonly live in buildings and are often referred to as “house bats.” The little brown bat (Myotis lucifugus) is the species most homeowners encounter in attics, walls, and barns, and it carries a legal status that changes everything about removal.
Little brown bats are endangered in Vermont, so you must fill out an Incidental Take Form on the Fish & Wildlife Department’s website within five days if a bat needs to be captured or killed and sent for rabies testing. That endangered listing exists because of a die-off that has reshaped the state’s bat population. Because of the dramatic declines in Vermont’s little brown bat population as a result of white-nose syndrome, large maternity colonies that might have been a concern before may now number just a few bats.
Vermont’s bats are in trouble, and the little brown bat is endangered in Vermont, so harming, harassing, or killing these bats violates the state’s endangered species law. The big brown bat is not currently listed as endangered, but it is still a native wild species subject to Vermont’s general wildlife protections, and Fish & Wildlife guidance directed at little brown bats “may also serve as a reference for addressing big brown bats.”
The statute behind this protection is 10 V.S.A. § 5408, Vermont’s endangered and threatened species law, which governs the taking, harassing, or possessing of listed wildlife statewide. This framework isn’t unique to bats. If you’re dealing with other nuisance animals on your property, Vermont’s broader wildlife removal laws apply many of the same take-permit principles.
Is It Legal to Remove Bats From Your Home in Vermont
Removing bats from a Vermont home is legal, but only through live exclusion. Vermont does not permit poisoning, fumigation, or lethal control as bat removal methods, and the state’s guidance is built entirely around non-lethal exclusion techniques that let bats leave on their own and prevent them from returning.
Pest control contractors need to become familiar with the Best Management Practices for Excluding Bats from Vermont Residences, and work conducted following those best management practices is exempt from requiring a State Threatened and Endangered Species Permit from the Secretary of the Vermont Agency of Natural Resources. In other words, the legal pathway exists, but it only stays legal if the exclusion follows the state’s approved steps.
Vermont’s approach mirrors, but doesn’t exactly match, how other states regulate bat exclusion. States like California, Minnesota, Arizona, and Virginia each set their own seasonal windows and permit thresholds for bat work, so a method that’s compliant across the border isn’t automatically compliant in Vermont.
Bat Exclusion Season and Restricted Dates in Vermont
Timing is the single most important compliance factor in Vermont bat removal. The state’s bat calendar tracks hibernation, migration, and pup-rearing cycles closely, and exclusion work outside the approved windows can trap flightless pups inside a structure or violate the endangered species rule outright.
The little brown bat hibernates in caves and mines from early fall to spring, typically emerging from hibernation in mid-April, and as it emerges, it returns to summer roosts commonly located in attics, under shutters and shingles, and in sheds, barns, and garages. Prior to white-nose syndrome, maternity colonies of female little brown bats varied in size from a few to hundreds of females, with each female giving birth to a single pup between the end of May and mid-July. The big brown bat hibernates in mines and caves as well but is the only species that will also hibernate in buildings during the winter.
| Period | What’s Happening | Exclusion Status |
|---|---|---|
| December – March | Little brown bats have migrated to caves and mines for the winter; big brown bats may remain in the structure | Generally avoided; risks trapping hibernating big brown bats |
| April – mid-May | Bats may be present, but pups are not yet born | Safe window for exclusion |
| Late May – mid-July | Pups are born and cannot yet fly | Exclusion prohibited (maternity season) |
| Mid-August – fall | Pups have fledged and can fly | Safe window for exclusion |
Vermont’s neighbors in New England follow a similar pattern. The maternity season for both little brown and big brown bats runs approximately June 1 through August 15 across the region, which lines up closely with Vermont’s own guidance. Outside New England, the calendar shifts with climate, which is part of why states such as North Carolina and Wisconsin set their own maternity-season dates rather than borrowing Vermont’s.
Important Note: Sources vary slightly on exact maternity-season end dates for Vermont, with some citing mid-July and others mid-August. Given that ambiguity, contacting Vermont Fish & Wildlife or a licensed nuisance wildlife control professional before scheduling exclusion work is the safest way to confirm current timing.
Approved Bat Removal Methods in Vermont
Vermont’s approved method for bat removal is a one-way exclusion system, not trapping, poisoning, or relocation. The process relies on devices that let resident bats leave a structure to feed at night but prevent them from flying back in.
- One-way excluders: Bat check valves, bat cones, or other one-way door excluders are installed over active openings that allow bats to exit but prevent their re-entry, and should effectively evict all resident bats in a few days.
- Netting or screening: Bat check valves can be made with nylon window screen material attached above and on the sides, extended two inches below the opening, with the bottom left loose enough for bats to exit underneath.
- Sealing entry points: Once bats have vacated through the excluder, remaining gaps in fascia boards, ridge caps, chimneys, and vents get permanently sealed to prevent re-entry.
- No lethal methods: Poisons, fumigants, and glue traps are not legal bat removal tools in Vermont and put an operator at risk of endangered species violations.
Because the little brown bat’s endangered status raises the legal stakes, many homeowners hire licensed nuisance wildlife control operators rather than attempting exclusion themselves. Vermont Fish & Wildlife maintains a list of nuisance wildlife control professionals for homeowners who want professional help excluding bats from a home. If you keep bees or plan to install bat houses as an alternative roost once bats are excluded, Vermont’s beekeeping laws offer a useful comparison for how the state balances backyard wildlife management with property rights.
Do You Need a Permit to Remove Bats in Vermont
Standard live exclusion performed within the approved season generally doesn’t require a separate permit application, but the exemption is conditional, not automatic. Work conducted by contractors following the best management practices is exempt from requiring a State Threatened and Endangered Species Permit, and animal damage and pest control professionals following those practices and reporting their activities will be identified for public inquiries as being in compliance with Vermont endangered species law.
Step outside those best management practices and the calculus changes. If a homeowner prefers to exclude bats from a building, specific steps should be practiced by the homeowner or their pest control agent, and measures that do not conform to those steps may require a State of Vermont Threatened and Endangered Species Permit.
A separate, narrower permit covers situations involving potential rabies exposure. Vermont’s General Permit authorizes the taking of certain endangered bats found within private residences, places of work, and public buildings so that Vermonters can respond quickly to a health threat, and the Secretary allows the incidental take of no more than four bats per year for the purposes described in the permit. If a captured bat needs rabies testing, you must fill out an Incidental Take Form within five days, and doing so avoids the penalties and fines normally associated with taking an endangered animal.
Vermont’s tiered permit system for wildlife take isn’t limited to bats. Waterfowl hunters navigating the state’s duck hunting laws encounter a similar structure of general permits layered under stricter individual permit requirements for protected situations.
What to Do If You Find a Bat Inside Your Home in Vermont
A single bat flying through a living room is a different situation than a colony in the attic, and Vermont’s recommended response starts with staying calm rather than chasing the animal.
- Stay calm. The bat wants out as badly as you want it out, and it is probably disoriented and lost.
- Keep pets and children away, then confine the bat to a single room and open windows and doors leading outside so it can escape.
- If the room is brightly lit, lower or shut off the lights, since bright light may disorient the bat and cause it to seek refuge behind pictures, bookcases, or curtains.
- If it doesn’t leave on its own, wait until it lands, then wearing thick protective leather gloves, quickly cover it with a coffee can or similar container and slide cardboard underneath to trap it before release.
Direct contact changes the protocol entirely. If you suspect a potential rabies exposure, call the rabies hotline at 1-800-4RABIES, the Department of Health, or your physician. Because the little brown bat’s protected status applies even to a single stray animal, capturing one for testing still triggers the same five-day Incidental Take Form requirement described above. If you’re also dealing with wildlife found dead on your property, Vermont’s roadkill laws outline separate rules for handling and reporting deceased animals.
Pro Tip: A single bat inside a living space in summer often means there’s a roost or colony elsewhere in the house. Check roof lines, chimneys, and attic vents for staining or guano before assuming it was a one-time visitor.
Penalties for Illegal Bat Removal in Vermont
Because the little brown bat is a listed endangered species, illegal removal isn’t treated as a minor wildlife infraction. Whoever violates provisions relating to threatened or endangered species is fined not more than $1,000.00 nor less than $400.00 or imprisoned for not more than 60 days, or both. A second and all subsequent convictions carry a fine of not more than $4,000.00 nor less than $2,000.00 or imprisonment for not more than 60 days, or both.
Enforcement isn’t limited to criminal fines. The Secretary may bring an environmental enforcement action against a violator, or instead refer violations to the Commissioner of Fish and Wildlife for criminal enforcement. That dual-track approach means a botched DIY exclusion during maternity season, or a pest control job that uses poison or traps instead of approved exclusion devices, can expose a homeowner or contractor to either administrative penalties or a criminal case, depending on how the state chooses to pursue it.

For a specific property or situation, consult the Vermont Agency of Natural Resources or a licensed attorney before proceeding with exclusion work.
Vermont’s bat removal framework exists because one of its most common house-dwelling species is fighting to recover from a population collapse most homeowners never see firsthand. Working within the state’s seasonal windows, using approved one-way exclusion devices, and filing the right paperwork when a rabies exposure occurs keeps a bat problem from becoming a legal one. When timing or method is unclear, Vermont’s list of licensed nuisance wildlife control professionals remains the most reliable way to resolve a colony without running afoul of the state’s endangered species law.
