The short version
Wildlife control involves humane removal of animals like raccoons, squirrels, and bats, followed by exclusion (sealing entry points) to prevent return. Professional help is recommended for safe, legal, and permanent solutions.
- Attics and chimneys are the most common entry points for nuisance wildlife.
- Humane exclusion is the only permanent solution; trapping alone is ineffective.
- State regulations protect many species; improper handling can be illegal.
- Spring denning and fall are peak seasons for wildlife intrusions.
- Professional removal costs $250-$600; exclusion and restoration average $1,000-$2,500.
For homeowners, property managers, and landlords dealing with nuisance wildlife in attics, basements, or chimneys. If you hear scratching in the walls, find droppings in the attic, or see animals entering your roof, this information will help you understand the problem, your options, and when to call a professional.
What to look for
Wildlife enters homes for food, warmth, and shelter. Raccoons and squirrels often access attics via soffits, vents, or damaged shingles. Bats can squeeze through gaps as small as 3/8 inch. Skunks and opossums may den under decks or porches. Once inside, animals create nests, damage wiring, and leave droppings that can harbor diseases. State regulations protect many species; for example, bats are often protected during maternity season, and raccoons may require special permits. Improper handling can lead to fines or injury. Professional wildlife control operators know the laws and use humane methods, including one-way doors and live traps, followed by exclusion to seal entry points permanently.
- 1Scratching, scurrying, or thumping noises in the attic or walls, especially at night.
- 2Droppings in the attic, near entry points, or on insulation.
- 3Visible entry holes in soffits, fascia, or roofline, often with greasy rub marks.
- 4Damaged vents, chewed wires, or torn insulation.
- 5Strong odors from urine or feces, especially from raccoons or skunks.
- 6Animal tracks or trails in snow, mud, or dusty attic spaces.
- 7Dead animals or strong decomposing smell (often from a trapped animal in a wall).
Why it’s worth acting soon
- Structural damage: chewed wood, wires (fire risk), and compromised insulation.
- Health hazards: raccoon roundworm, bat guano (histoplasmosis), rabies exposure.
- Secondary infestations: fleas, ticks, and mites carried by wildlife.
- Legal penalties for harming protected species or improper removal.
- Increased cost: delayed repairs often require extensive restoration.

In the attic, look for flattened insulation, droppings and nests. Leave big cleanups to someone with the right gear.The Biology of Nuisance Wildlife.
Raccoons are highly intelligent and dexterous, capable of opening latches and tearing shingles. They are nocturnal and typically have litters of 3-5 kits in spring. Squirrels, especially gray squirrels, are diurnal and can enter attics through tiny gaps, chewing wood and wires. They have two breeding seasons: late winter and mid-summer. Opossums are North America's only marsupial; they are nomadic and rarely stay in one den for long, but will take advantage of easy access. Skunks are known for their spray, which is a potent musk that can linger for weeks. Bats are often protected; the little brown bat can eat up to 1,000 mosquitoes per hour, but guano buildup in attics can cause histoplasmosis. Understanding the behavior of each species is critical for effective control. For example, raccoons often create latrines (communal defecation sites) on roofs or in attics, which can spread raccoon roundworm eggs. Squirrels will gnaw on electrical wires, causing fire risks. Opossums are generally harmless but can carry fleas and ticks. Skunks spray only when threatened, but their spray can cause nausea and temporary blindness. Bats form colonies; removing them requires careful timing to avoid trapping young inside. Professionals use species-specific strategies. For raccoons, exclusion doors and live traps are common. Squirrels may be excluded with one-way doors, but their persistence requires sealing all potential entry points. Bats require exclusion tubes or netting, and often a waiting period during maternity season (May-August) when young are flightless. Proper cleanup and insulation replacement are essential after any wildlife removal to eliminate odors and prevent re-infestation.
wildlife activity by season.
The most useful first step in Emergency Wildlife Control is to note where you have seen wildlife and when they appear, because that timeline is what lets a provider focus on the right area instead of treating the whole property. In Emergency Wildlife Control, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure usually turns up the conditions that are letting them in. Scheduling before the busy stretch, rather than after it, tends to mean faster service and a more accurate quote, and a local provider can point out the conditions that matter most in Emergency Wildlife Control.
Walk the foundation with a flashlight. Gaps at ground level let animals under the house.State Regulations and Legal Considerations.
Some even mandate that insulation be replaced after a bat infestation. Professionals understand these requirements and can provide documentation for insurance purposes. Always verify that your wildlife removal company is licensed and insured in your state. Wildlife control is heavily regulated in the United States. Most states require a permit for trapping and relocating certain species, and some prohibit relocation entirely due to disease transmission risks. For example, in many states, raccoons and skunks are considered rabies-vector species and cannot be relocated; they must be euthanized. Bats are often protected, and exclusion may be prohibited during maternity season. Squirrels and opossums may have fewer restrictions, but local ordinances vary. Penalties for non-compliance can be severe, including fines and loss of license. Professional wildlife control operators are trained in these laws and maintain the necessary permits. They also follow humane guidelines set by the National wildlife control Operators Association (NWCOA). When you hire a professional, you avoid legal risks and ensure that animals are handled ethically. Moreover, many states require that exclusion repairs be done to prevent future entry.
The Exclusion Process: Step by Step.
Exclusion is the cornerstone of permanent wildlife control. The process begins with a thorough inspection of the entire exterior and interior of the home, identifying all potential entry points. Common points include: roofline gaps, soffit vents, ridge vents, chimney tops, gable vents, foundation vents, and gaps around pipes and cables. Professionals use ladders, borescopes, and sometimes cameras to inspect attics and crawlspaces. Once all entry points are identified, the next step is to ensure no animals are trapped inside. This may involve installing one-way doors or using live traps. For bats, exclusion nets are placed over openings, allowing bats to exit but not return. After confirming that all animals have left (usually after 3-7 days), the entry points are permanently sealed with materials that animals cannot chew through, such as 1/4-inch hardware cloth, heavy-gauge steel mesh, or sheet metal. Gaps around pipes are sealed with copper mesh and expanding foam designed for pest control. restoration may be needed: removal of contaminated insulation, sanitization with enzyme cleaners, and replacement with new insulation. This step is crucial for health and to remove odors that might attract other animals. A good exclusion job comes with a warranty, often 1-5 years, giving homeowners peace of mind.
What affects the price
- Number of animals and species (bats often cost more due to colony size).
- Size of the infestation and duration of occupation.
- Complexity of exclusion: roof pitch, multiple entry points, hard-to-reach areas.
- State regulations and permit fees.
- Extent of damage requiring insulation removal and replacement.
- Time of year: spring and fall are peak seasons, potentially higher demand.

What wildlife issue are you most concerned about?
When to call for help
Call a professional immediately if you hear wildlife in the walls or attic, see signs of entry, or suspect a bat colony. DIY removal is risky—animals may be protected, and improper sealing can trap animals inside, causing death and odor.
What you can do yourself
DIY wildlife removal is usually ineffective and can be dangerous. Setting traps without knowledge of laws may be illegal. Sealing entry points without first ensuring all animals are out can trap them, leading to dead animals and foul odors. Professionals use methods like one-way doors and thorough exclusion, backed by experience and insurance. While DIY may seem cheaper upfront, professional exclusion is the only permanent solution and often saves money in the long run.
Where you live matters
State laws also differ significantly. For example, California prohibits relocation of most wildlife, while Texas allows it with a permit. Some states have specific seasons for trapping. Always check your state's wildlife agency website for regulations. Service is available statewide. Whether you're in a suburban neighborhood or rural area, the same principles apply: humane removal, thorough exclusion, and professional restoration. Wildlife issues vary by region. In the Northeast, raccoons and squirrels are the top nuisance animals, often entering homes through rooflines and chimneys. In the Southeast, opossums and armadillos are common under decks and porches. The Midwest sees many skunk problems, especially during spring denning. In the West, bats and squirrels are prevalent, and drought can drive animals closer to homes in search of water.
Simple ways to keep wildlife away
- Inspect your attic, roof, and foundation for gaps and seal them with heavy-duty materials (steel mesh, caulk, or sheet metal).
- Trim tree branches away from your roof to prevent squirrel and raccoon access.
- Install chimney caps and cover vents with hardware cloth.
- Secure trash cans with tight lids and avoid leaving pet food outside.
- Remove bird feeders and bird baths that attract wildlife.
- Store firewood at least 20 feet from your home to reduce denning sites.
Ask which animal it is, how babies will be handled, and whether sealing and cleanup are included.Did you know?
Opossums are largely immune to most snake venom and eat thousands of ticks per season.
Each year, squirrels plant thousands of trees simply by failing to remember where they stashed their nuts.
A single bat can eat up to 1,000 mosquitoes in one hour.
Questions people ask
What should I do if I hear scratching in my attic?
Contact a professional wildlife control company to inspect and determine the species. They will use humane methods to remove the animal and seal the entry points. Do not block the entry point.
Can I remove wildlife myself?
Many species are protected by law, and improper removal can be dangerous and ineffective. Professionals ensure humane, legal, and permanent solutions. It's not recommended.
How much does wildlife removal cost?
Typically $250-$600 for removal, and $1,000-$2,500 for full exclusion and restoration. Costs vary by species, infestation size, and region.
What is the best way to keep raccoons out?
Secure trash cans, trim tree branches, and install chimney caps. Professional exclusion is the most reliable method. Seal all potential entry points with heavy-duty materials like steel mesh.
How do I know if I have bats in my attic?
Look for droppings (guano) that accumulate in piles, a strong ammonia smell, and squeaking sounds at dusk and dawn. You may also see bats exiting at sunset.
Is wildlife removal covered by homeowners insurance?
Most policies exclude animal damage, but some may cover repairs after removal. Check your policy or ask your agent. Typically not.
Can my neighbor feeding wildlife cause problems at my house?
In Emergency Wildlife Control, nuisance wildlife is usually removed by trapping, then the entry points are sealed so the next animal cannot move into the same spot. In Emergency Wildlife Control, because many animals are protected by state rules, removal has to be done legally, and a written plan should spell out removal, exclusion, and cleanup.
