Nuisance Wildlife Laws in California: What Property Owners Must Know
June 2, 2026
California is home to an extraordinary range of wildlife — and sooner or later, some of it will show up where you don’t want it. A raccoon in the attic, a skunk under the deck, a coyote eyeing your chickens, or a bear raiding your trash can all feel like urgent problems that demand immediate action.
Before you reach for a trap or call the first pest control company you find, you need to understand one important reality: nuisance wildlife laws in California are among the most detailed and strictly enforced in the country. Getting it wrong can mean fines, criminal charges, and the permanent loss of hunting and fishing privileges.
This guide walks you through exactly what qualifies as nuisance wildlife, what your rights are as a property owner, and which methods, permits, and professionals are legally authorized under California law.
Important Note: This article is for informational purposes only and does not constitute legal advice. Wildlife regulations can change. Always verify current rules with the California Department of Fish and Wildlife (CDFW) or a licensed wildlife professional before taking action.
What Counts as Nuisance Wildlife in California
California does not use the term “nuisance wildlife” as a standalone legal category the way some other states do. Instead, the state organizes wild animals into classifications — game mammals, furbearing mammals, nongame animals, and fully protected species — and the rules for dealing with a conflict depend entirely on which category the animal falls into.
That said, under California Civil Code Section 3479, anything that is injurious to health, offensive to the senses, or an obstruction to the free use of property that interferes with comfortable enjoyment of life is legally considered a nuisance. Wildlife that damages structures, destroys crops, threatens livestock, or poses a health or safety risk generally falls within this framework.
In practical terms, animals that most commonly trigger nuisance conflicts in California include:
- Raccoons, opossums, and skunks invading attics, crawl spaces, or yards
- Ground squirrels and gophers damaging lawns, gardens, and agricultural land
- Coyotes threatening pets or livestock
- Bears accessing trash, gardens, or outbuildings
- Wild pigs destroying crops and property
- Deer and elk damaging orchards or agricultural operations
- Bats roosting in structures
Wildlife removal laws in California are shaped by the California Fish and Game Code, regulations enforced by the California Department of Fish and Wildlife (CDFW), and in some cases, federal protections that layer on top of state rules. Understanding which category an animal falls into — and what steps you’re legally allowed to take — is the first thing you need to figure out before you touch a trap, call a contractor, or attempt any removal on your own.
Key Insight: The animal’s legal classification — not just its behavior — determines what removal methods are available to you. A raccoon and a mountain lion both cause problems, but your legal options for each are dramatically different.
Your Rights as a Property Owner in California
As a property owner or tenant in California, you do have legal standing to address wildlife conflicts on your land — but those rights come with significant conditions attached. The state does not give you blanket authority to trap, kill, or remove any animal simply because it is causing a problem.
A person who is a property owner or tenant may apply to the department for a permit to take elk, bear, bobcat, beaver, wild pigs, deer, wild turkeys, or gray squirrels that are damaging or destroying, or immediately threatening to damage or destroy, land or property. This permit process is not automatic — you must demonstrate active or imminent property damage and apply through the CDFW’s online Wildlife Incident Reporting (WIR) system.
For certain lower-risk nongame animals, your rights are broader. Nongame animals that may be taken any time of year and in any number — except as otherwise prohibited — include English sparrows, starlings, domestic pigeons, coyotes, weasels, skunks, opossums, moles, and rodents. This means you have more flexibility when dealing with these species, though trapping rules and humane methods requirements still apply.
Your core rights as a California property owner in a wildlife conflict include:
- The right to apply for a depredation permit when covered species are actively damaging your property
- The right to use exclusion methods (sealing entry points, removing attractants) at any time without a permit
- The right to trap certain nongame species on your own property, subject to trapping regulations
- The right to hire a licensed wildlife control operator to act on your behalf
- The right to immediately kill a mountain lion that is in the act of attacking a domestic animal or poses an imminent threat to human life, provided you notify CDFW immediately afterward
What you do not have the right to do is relocate trapped animals, use prohibited trap types, or take action against protected or fully protected species without proper authorization. Understanding those limits is just as important as knowing what you can do. For a broader look at how California regulates animals and their owners, see pet laws in California.
Legal Methods for Removing Nuisance Wildlife in California
California prioritizes non-lethal approaches first. Wildlife management strategies in California emphasize the importance of prevention and non-lethal methods whenever possible, seeking to resolve conflicts between humans and wildlife without resorting to lethal measures. When non-lethal options are not sufficient, specific lethal methods are permitted — but only for certain species and under defined conditions.
Non-Lethal Methods
Non-lethal removal is always the safest legal path and requires the fewest permits. Humane techniques involve strategies such as exclusion, habitat modification, and repellents to deter wildlife from unwanted areas without causing harm. These approaches include:
- Exclusion: Sealing entry points, installing chimney caps, reinforcing crawl space vents, and using wire mesh to block access
- Habitat modification: Removing food sources such as unsecured trash, fallen fruit, pet food left outdoors, and bird feeders that attract predators
- Repellents: Motion-activated sprinklers, lights, and commercially available chemical deterrents
- Hazing: Non-harmful deterrents to discourage wildlife from returning to an area
Trapping
California regulates not just what you can trap, but exactly how you can do it. The state’s trapping laws are detailed in Title 14 of the California Code of Regulations and the Fish and Game Code, and violations carry real consequences.
Key trapping requirements under California law include:
- Trap identification: It is illegal to set or maintain traps that do not bear a number or other identifying mark registered with the Department of Fish and Wildlife. This includes a property owner who wishes to set a trap for a wild animal in their backyard — before doing so, they must receive an identifying number and affix it to the trap.
- Daily inspection: Traps must be inspected and all animals in the traps must be removed at least once daily. The inspection and removal must be done by the person who sets the trap or the owner of the land where the trap is set.
- Trap placement: Traps may not be set within 150 yards of any structure used as a permanent or temporary residence, unless such traps are set by a person controlling such property or by a person who has and is carrying written consent of the landowner to place the trap or traps. Simply put, no person may set a trap within 150 yards of a residence without written consent from the owner of that residence.
- Conibear trap restrictions: You may not use a conibear trap larger than 6 inches by 6 inches unless it is partially or wholly submerged in water.
- Metal-jawed traps: An iron-jawed, steel-jawed, or any type of metal-jawed trap shall not be used to take any bear or bobcat.
Lethal Removal
Lethal removal of certain nongame species on your property may be permitted without a formal depredation permit. For game mammals and furbearers, however, you generally need a permit from CDFW. Any owner or tenant of land or property that is being damaged or destroyed, or is in danger of being damaged or destroyed, by elk, bear, bobcat, beaver, wild pig, wild turkeys, or gray squirrels may apply to the department for a permit to kill the animals. Upon satisfactory evidence of the damage or destruction, actual or immediately threatened, the department shall issue a revocable permit for the taking and disposition of the animals under regulations adopted by the commission.
Note that only non-lead ammunition is permitted for taking wildlife with a firearm in California. This includes all types of hunting — public or private land, licensed or unlicensed hunters — and applies to rifles, shotguns, pistols, and muzzleloaders. This directive aims to protect California wildlife from lead poisoning.
Pro Tip: Before setting any trap, contact your local CDFW regional office to confirm whether the target species requires a permit and which trap types are authorized. A quick call can prevent a costly mistake.
Relocation Rules in California
This is where many well-intentioned property owners unknowingly break the law. The instinct to trap a raccoon and drive it to a park or open space feels humane — but in California, it is illegal.
It is illegal in the State of California to relocate nuisance wildlife, and most animal control agencies will not accept them. This rule applies to furbearing and nongame mammals that are legally trapped.
The reasoning behind the prohibition is rooted in disease transmission, ecological disruption, and animal welfare — relocated animals often die from stress or territorial conflict with established wildlife in the release area.
Trapped animals must be immediately euthanized or released on site. Relocation of trapped wildlife is prohibited. This means that if you legally trap a raccoon, opossum, or squirrel, your only lawful options are to release it on the same property or have it humanely euthanized. You cannot drive it to a park, open space, or neighboring county and release it there.
Exceptions to the Relocation Ban
There are narrow exceptions to the relocation prohibition. The CDFW may authorize relocation in specific circumstances, typically involving large depredatory mammals handled by authorized professionals.
If you want to avoid killing a trapped animal, your legal options are:
- Release it on-site immediately and address the attractants or entry points that brought it in
- Use exclusion methods before any animal is trapped so removal is unnecessary
- Contact a licensed wildlife control operator who may be authorized to handle certain relocations under specific permit conditions
- Reach out to a permitted wildlife rehabilitator if the animal is injured or orphaned
This relocation prohibition reflects the same overarching legal philosophy you’ll find in roadkill laws in California — the state takes wildlife possession and transport seriously, even when intentions are good.
Common Mistake: Driving a trapped animal to a nearby park or nature area and releasing it there is one of the most frequent violations California property owners commit — often without knowing it’s illegal. Always release on-site or euthanize humanely.
Species With Special Rules in California
Several species in California carry additional legal protections that go well beyond standard nuisance wildlife rules. Treating these animals the same as a common opossum or squirrel can result in serious criminal penalties.
Mountain Lions
Mountain lions are a specially protected mammal under California law. It is unlawful to take, injure, possess, transport, import, or sell a mountain lion or any product of a mountain lion, except as specifically provided in the relevant chapter.
If a mountain lion is found in the act of attacking a domestic animal or is seen as an immediate threat to human life, it may be killed by a resident without repercussion, as long as the CDFW is immediately notified after the incident. CDFW will confirm it was the only option to prevent loss of life to people or property.
If the Department finds there was no immediate danger, a shooter can be prosecuted for poaching since mountain lions are a specially protected mammal in California. A violation of California’s mountain lion protection laws is a misdemeanor punishable by imprisonment in the county jail for not more than one year, or a fine of not more than ten thousand dollars ($10,000), or both.
Bears
Black bears are a game mammal in California and require a depredation permit before you can legally take one that is causing property damage. Any owner or tenant of land or property that is being damaged or destroyed by bear may apply to the department for a permit to kill the animals. Metal-jawed traps are prohibited for bears, and all carcasses must be handled according to CDFW instructions.
Fully Protected Species
Several species are classified as “Fully Protected,” which strictly prohibits their take or possession at any time, with limited exceptions for scientific research. If you encounter a fully protected species, do not attempt any removal — contact CDFW immediately. Fully protected mammals in California include the marten, fisher, wolverine, golden eagle, and certain other species listed under the California Endangered Species Act (CESA).
Migratory Birds
Many birds — including swallows, swifts, and most songbirds — are protected under the federal Migratory Bird Treaty Act (MBTA), which layers on top of California state law. You cannot remove active nests, eggs, or nesting birds without a federal permit. This is a frequent issue for homeowners dealing with birds nesting in eaves, rafters, or vents.
Coyotes
Coyotes can cause serious damage to people and property, including domestic animals and livestock. In general, you can trap and kill depredating coyotes all year long. However, you have to follow hunting rules for California Coyote Hunting Seasons and Trapping. Coyotes are classified as nongame mammals, giving property owners more flexibility — but trapping regulations still apply.
Wild Pigs
Wild pigs are considered both a big game species and a nuisance, leading to year-round wild pig hunting opportunities. With respect to wild pigs, the department shall provide an applicant for a depredation permit with written information that sets forth available options for wild pig control, including depredation permits, allowing periodic access to licensed hunters, and holding special hunts. The department shall not limit the number of wild pigs to be taken under a depredation permit or based on the sex of the wild pig.

When You Need a Licensed Wildlife Control Operator in California
For many wildlife conflicts in California, hiring a licensed wildlife control operator (WCO) is not just a convenience — it may be the only legal path forward. For most wildlife conflicts involving game animals, furbearers, or protected species, hiring a licensed wildlife control operator is not just the smart choice — it may be the only legal one.
When a License Is Required
Trapping nuisance animals for hire requires a license. The target species will determine what type of license and/or permit from the California Department of Fish and Wildlife you will need.
You should strongly consider — or are legally required — to hire a licensed WCO in these situations:
- Dealing with any game mammal (deer, bear, elk, bobcat, beaver, wild turkey, gray squirrel) that requires a depredation permit
- Handling a mountain lion conflict of any kind
- Removing bats from a structure (bat exclusion has specific timing and method requirements)
- Dealing with any fully protected or CESA-listed species
- Addressing a wildlife conflict on commercial or rental property
- Any situation where you are uncertain about the species, the applicable law, or the correct method
What to Look for in a Licensed Operator
A qualified WCO in California should hold a valid Trapping License issued by CDFW, any required depredation or special permits for the target species, and carry liability insurance. Ask for their license number and verify it with CDFW before work begins.
Individuals must obtain a wildlife removal permit from the California Department of Fish and Wildlife before engaging in many wildlife removal activities. That said, not every animal requires a permit, and not every situation triggers the same rules. A licensed operator will know exactly which permits apply to your specific situation.
Pro Tip: When hiring a wildlife control operator, ask them to explain in writing which permits they hold and how they intend to handle the trapped animal. Any operator who suggests relocating a furbearing mammal to another area should be a red flag — that is illegal under California law.

Penalties for Violating Nuisance Wildlife Laws in California
California takes wildlife law enforcement seriously, and the penalties for violations can be far more severe than most people expect. Enforcement of the Code and its regulations falls to California Fish and Wildlife Wardens, who are state peace officers authorized to enforce all state laws. Violations are categorized as infractions, misdemeanors, or felonies.
Standard Penalties
| Violation Type | Potential Penalty |
|---|---|
| Standard misdemeanor (Fish and Game Code Section 12002) | Fine up to $1,000, up to 6 months in county jail, or both |
| Serious offenses (unlawful take, exceeding bag limits) | Fine up to $2,000, up to 1 year in jail |
| Mountain lion violation | Fine up to $10,000, up to 1 year in county jail, or both |
| Threatened or endangered species violation (CESA) | Fines from $25,000 to $50,000 per violation, potential imprisonment |
| Illegal trapping or relocation | Fines, equipment seizure, license revocation |
A standard misdemeanor violation of the Code is punishable by a fine of up to $1,000, imprisonment in a county jail for up to six months, or both. More serious offenses, such as exceeding bag limits or unlawful take, can incur fines up to $2,000 and one year of jail time.
Court-imposed penalties, including mandatory assessments and restitution, can dramatically increase the financial consequence — a violation involving the illegal take of a trophy deer can result in total penalties exceeding $20,000. Severe or repeated violations can also lead to the mandatory seizure of equipment used in the crime and the permanent revocation of all hunting and fishing privileges.
Violations concerning threatened or endangered species carry severe penalties, including fines ranging from $25,000 to $50,000 per violation and potential imprisonment, as authorized by Fish and Game Code Section 12008.
Additional Consequences
Beyond the direct fines and jail time, violations can also result in:
- Confiscation of property used in the commission of wildlife crimes, such as traps or illegal hunting equipment
- Probation, requiring offenders to adhere to specific conditions set by the court
- In severe cases, criminal charges that can result in imprisonment and a permanent mark on the offender’s legal record
The bottom line: the cost of doing things wrong in California almost always exceeds the cost of doing them right. If you’re uncertain about any aspect of a wildlife conflict — the species, the legal method, or whether a permit is required — contact the CDFW, consult a licensed wildlife control operator, or review California’s official hunting and trapping regulations before taking any action.
For additional context on how California’s animal laws work across different situations, see dog leash laws in California and goat ownership laws in California. If you’re curious how other states approach these same issues, wildlife removal laws in Florida, wildlife removal laws in Georgia, and wildlife removal laws in New York each take a notably different approach from California’s strict framework.
Conclusion
Dealing with nuisance wildlife on your California property requires more than a trap and a plan — it requires knowing the law. The state’s framework is built on a clear principle: wildlife belongs to the public trust, and your right to remove it is conditional, not absolute.
The most important rules to keep in mind are these: know the species before you act, use only legal methods, never relocate a trapped animal off-site, and call a licensed professional when the situation involves a game mammal, protected species, or anything you’re uncertain about. Taking shortcuts might seem faster in the moment, but in California, the legal and financial consequences of getting it wrong are severe enough to make doing it right the only sensible option.
