Hawaii has some of the most protective wildlife laws in the United States — and for good reason. The islands are home to hundreds of native species found nowhere else on Earth, and decades of damage from introduced predators and invasive animals have made the state extremely cautious about how wildlife is handled, moved, or removed.
If you are dealing with a nuisance animal on your property, knowing the rules before you act is not optional — it is essential. The wrong move can result in criminal charges, steep fines, or unintended harm to species protected under state and federal law. This guide walks you through what Hawaii law allows, what it prohibits, and how to stay on the right side of the rules.
Can You Remove Wildlife Yourself in Hawaii?
The short answer is: sometimes, but rarely without restrictions. The Department of Land and Natural Resources (DLNR) regulates the transport and release of wildlife and manages both aquatic and terrestrial resources across the state. That regulatory reach covers far more than most homeowners expect.
No person shall hunt, pursue, kill, or take any game bird or mammal without first procuring a hunting license — though no license is required of persons who may be authorized in writing by the board to destroy game birds or game mammals injurious to forest growth or agriculture, or that constitute a nuisance or a health hazard. That written authorization requirement is the key detail most residents overlook.
For common nuisance animals like rats, mice, and feral cats, you generally have more flexibility on your own property. But the moment an animal crosses into a protected category — native birds, endangered species, or any animal classified as “injurious wildlife” — you need a permit before doing anything beyond basic exclusion. When in doubt, call the DLNR before acting.
Pro Tip: Exclusion methods — sealing entry points, removing food sources, and installing physical barriers — are always legal and are your best first line of defense before considering trapping or removal.
Hawaii’s rules also vary by island and by the specific land you occupy. More than one permit may be required depending on the location and type of activity, as well as the species impacted by the activity. If you live near a conservation district, a game management area, or a wildlife refuge, additional restrictions almost certainly apply to your situation.

Which Animals Can Be Removed Without a Permit in Hawaii?
Hawaii’s wildlife framework draws a firm line between introduced pest species and protected native wildlife. On your own private property, you generally do not need a permit to control the following animals:
- Rats and mice — Roof rats (Rattus rattus), Norway rats (Rattus norvegicus), and house mice (Mus musculus) are considered invasive rodents and may be trapped or killed on private property without a permit using standard snap traps, glue traps, or rodenticides labeled for residential use.
- Feral pigeons — Rock pigeons (Columba livia) are non-native birds not protected under the Migratory Bird Treaty Act and may be controlled on your property.
- Feral chickens — Particularly common on Kauai and Oahu, feral chickens are not protected under state wildlife statutes and can be removed from private property, though local county ordinances may apply.
- Common house geckos — The introduced house gecko (Hemidactylus frenatus) is not a protected species and can be removed without a permit.
Under Hawaii Revised Statutes Chapter 183D, “predators” are defined as animals destructive of wildlife by nature of their predatory habits, including mongooses, cats, dogs, and rats. This classification reflects the state’s recognition that these introduced species cause serious harm to native wildlife — but it does not automatically grant the public unlimited authority to kill or relocate them. Mongooses, in particular, fall into a gray area that requires careful attention (covered in the next section).
Important Note: County ordinances on Oahu, Maui, Kauai, and Hawaii Island may add another layer of rules on top of state law. Always check with your county’s animal control division before removing any animal, even one that appears unprotected under state statute.
Which Animals Require a Licensed Wildlife Removal Professional in Hawaii?
Hawaii’s native species receive strong legal protection, and attempting to handle them without authorization exposes you to serious legal consequences. The following categories require a licensed professional or DLNR authorization:
Native Hawaiian birds: Species like the nene (Hawaiian goose, Branta sandvicensis), the pueo (Hawaiian short-eared owl, Asio flammeus sandwichensis), and all native forest birds are protected under both the Hawaii Endangered Species Law (HRS Chapter 195D) and the federal Migratory Bird Treaty Act. Hawaii’s endangered species law prohibits any taking, transport, or commerce in designated species. You cannot trap, relocate, or disturb a nest without state and potentially federal permits.
Hawaiian monk seals and sea turtles: A person commits the offense of taking a monk seal if the person intentionally or knowingly interferes with one. The Hawaiian monk seal (Neomonachus schauinslandi) and all sea turtle species are federally endangered. If one ends up on your beach or near your home, your only legal option is to keep people and pets away and call DLNR or the National Oceanic and Atmospheric Administration (NOAA) immediately.
Migratory birds: For studies or activities involving federally protected species, such as migratory birds and threatened and endangered species, federal permits must be obtained prior to initiation of any fieldwork. This applies equally to removal activities on private land.
Game mammals in certain contexts: Deer, pronghorn, goat, sheep, cattle, pig, and any other mammal that has been introduced into the state and released for hunting for which a hunting season is established by law or rule are designated as game mammals when living in a wild or feral state. Removing these animals outside of a licensed hunting season or without DLNR authorization is prohibited.
Injurious wildlife: Hawaii Administrative Rules Chapter 124 defines “injurious wildlife” as any species or subspecies of animal known to be harmful to agriculture, aquaculture, indigenous wildlife or plants, or that constitutes a nuisance or health hazard and is listed in the injurious wildlife exhibit. Unless permitted by DLNR, it is prohibited to release, transport, or export injurious wildlife.

Trapping Rules and Legal Methods in Hawaii
Hawaii does not have a standalone commercial trapping industry the way many mainland states do, but trapping is regulated under DLNR’s administrative rules and varies significantly by species and location.
Legal methods for pest species on private property:
- Snap traps for rodents
- Glue boards for rodents (indoors)
- EPA-registered rodenticides following label directions
- Live cage traps for feral cats and chickens (subject to what you do with the animal afterward — see the relocation section below)
- Physical exclusion and one-way doors for animals entering structures
Methods that require DLNR authorization:
- Trapping on state-managed lands, game management areas, or natural area reserves
- Any trapping targeting game mammals or protected birds
- Use of body-gripping traps, snares, or poisons beyond standard rodenticides
Statutes and rules related to the Division of Forestry and Wildlife can be enforced through three systems: the Civil Resource Violation System, which allows officers to issue civil monetary penalties; the criminal enforcement system, which carries criminal penalties including fines and jail time processed through the Hawaii District Court System; and Board Actions, which can issue administrative monetary fines.
It is the individual’s sole responsibility to ensure that all applicable permits are held prior to commencement of regulated activities. That responsibility applies to trapping just as much as it does to any other wildlife interaction.
Pro Tip: If you are trapping feral cats on your property, coordinate with your county humane society or a licensed trap-neuter-return (TNR) program before setting traps. Releasing a cat you have trapped — even back where you found it — may implicate DLNR rules on the transport of animals classified as predators.
USDA Wildlife Services also operates a Hawaii field station that conducts research and control operations for invasive species like mongooses and feral pigs, often in partnership with DLNR. Homeowners dealing with agricultural pest problems may be able to request technical assistance from this program.
Can You Relocate Wildlife in Hawaii?
Relocation of wildlife in Hawaii is far more restricted than in most mainland states, and in many cases it is outright prohibited. Hawaii’s island ecosystem makes relocation especially problematic: an animal moved from one location can easily spread disease, displace native species, or establish a new invasive population in a previously unaffected area.
Unless permitted by DLNR, it is prohibited to release, transport, or export injurious wildlife. That prohibition covers a wide range of animals that might seem like reasonable candidates for relocation.
For migratory bird species specifically, federal research has shown that relocation is not a viable solution in Hawaii’s island context. Trap and relocation of cattle egrets and barn owls was considered, but these species cannot be relocated within the Hawaiian archipelago due to their ability to travel between islands, return to the site from which they were captured, and perpetuate the conflict with endangered and threatened species.
For game mammals like feral pigs and goats, relocation is also generally prohibited without DLNR authorization. DLNR’s Division of Forestry and Wildlife conducts animal control activities including trapping, ground and aerial shooting for feral goats, feral sheep, mouflon, and mouflon/feral sheep hybrids within critical habitats on Hawaii Island. These are state-managed operations — not something a private landowner can replicate independently.
The practical takeaway: if you trap an animal on your property in Hawaii, you need a plan that complies with DLNR rules before you open the trap door. Releasing it elsewhere on the island without authorization is likely a violation. Contact DLNR or a licensed wildlife control operator to determine the legally approved disposition for the specific animal you have caught.
This stands in contrast to states like Colorado or Tennessee, where relocation of certain nuisance species to suitable habitat is a standard and permitted practice under state wildlife rules.
Hiring a Licensed Wildlife Control Operator in Hawaii
Hawaii does not operate a formal state-issued “wildlife control operator” (WCO) license program identical to those found in many mainland states. However, that does not mean professional wildlife removal is unregulated. Anyone conducting wildlife removal commercially must comply with DLNR permit requirements for any protected, game, or injurious species they handle.
When hiring a wildlife removal professional in Hawaii, look for the following:
- DLNR permit documentation — Ask the company to show any active permits issued by the Division of Forestry and Wildlife for the species they plan to handle on your property.
- USDA Wildlife Services coordination — For agricultural or large-scale pest problems, reputable operators often work in coordination with or have training from USDA APHIS Wildlife Services.
- Island-specific experience — Regulations and species vary significantly between Oahu, Maui, Kauai, and Hawaii Island. A company that primarily operates on one island may not be familiar with the rules on another.
- Written service agreement — Get a written plan that specifies the methods to be used, how captured animals will be handled, and who is responsible for permit compliance.
- County business license — Each county in Hawaii requires business licensing. Verify the operator is properly licensed to conduct business in your county.
You can help protect Hawaii’s natural resources by reporting violations to DLNR DOCARE at 643-DLNR (643-3567), or via the DLNRTip app. If a wildlife removal company is operating without proper authorization, that tip line is the appropriate place to report it.
For a sense of how formal WCO licensing structures work in other states, see wildlife removal laws in New York, wildlife removal laws in Ohio, or wildlife removal laws in Virginia — all of which maintain dedicated licensing programs for nuisance wildlife control.
| Animal Type | DIY Removal Allowed? | Permit Required? | Professional Recommended? |
|---|---|---|---|
| Rats / mice | Yes (private property) | No | For large infestations |
| Feral chickens | Yes (private property) | No (check county rules) | Optional |
| Mongooses | Limited (on-property control) | Required for transport/release | Yes |
| Feral pigs / goats | Only with hunting license in season | Yes (outside hunting season) | Yes |
| Native birds (nene, pueo, etc.) | No | Yes (state + federal) | Required |
| Hawaiian monk seals / sea turtles | No | Yes (federal) | Call NOAA / DLNR immediately |
| Migratory birds | No | Yes (federal) | Required |
Penalties for Illegal Wildlife Removal in Hawaii
Hawaii enforces its wildlife laws through multiple channels, and penalties can be significant. The state takes violations seriously, particularly when they involve native or endangered species.
Enforcement operates through three parallel systems: the Civil Resource Violation System (CRVS), which allows DOCARE officers to issue monetary fines similar to parking tickets; the criminal enforcement system, which carries fines and potential jail time processed through the Hawaii District Court; and Board Actions, which issue administrative monetary fines from the Board of Land and Natural Resources. DLNR may seek a combination of civil penalties, criminal penalties, or board actions for violations.
Under Hawaii’s endangered species statute, violation of the regulations results in a misdemeanor conviction with both criminal fines and administrative fines that graduate for subsequent convictions. Repeat offenders face escalating penalties.
At the federal level, violations of the Migratory Bird Treaty Act carry fines of up to $15,000 per bird and potential imprisonment. Violations involving federally listed endangered species under the Endangered Species Act can result in civil penalties up to $25,000 per violation and criminal penalties up to $50,000 and one year in prison for knowing violations — figures that apply regardless of whether the removal occurred on private property.
Beyond fines and criminal exposure, it is the individual’s sole responsibility to ensure that all applicable permits are held prior to commencement of regulated activities — meaning “I didn’t know” is not a recognized defense under Hawaii’s wildlife statutes.
Important Note: If you accidentally injure or kill a protected species while attempting legal pest control — for example, a snap trap meant for rats kills a native bird — report it to DLNR immediately. Proactive reporting is treated very differently from concealment, and cooperation with DLNR can significantly affect how a case is handled.
Common violations that result in enforcement actions include:
- Trapping or killing a game mammal outside of a licensed hunting season without DLNR authorization
- Transporting or releasing injurious wildlife without a permit
- Disturbing a Hawaiian monk seal, sea turtle, or native bird nest
- Using prohibited trapping methods on state-managed lands
- Hiring an unlicensed operator who then violates DLNR rules on your property
For reference, you can review how penalties are structured in other states by reading about wildlife removal laws in Texas, wildlife removal laws in Georgia, or wildlife removal laws in North Carolina.
The bottom line in Hawaii is straightforward: the state’s island ecosystem is irreplaceable, and the laws reflect that reality. When you are unsure whether an action is legal, contact the DLNR Division of Forestry and Wildlife directly before proceeding. A quick phone call is far less costly than a wildlife violation on your record.
