Wyoming Wildlife Control: The Homeowner’s Guide to Removal & Exclusion
Wyoming’s wide-open spaces bring you close to nature—sometimes too close. When a raccoon takes up residence in your attic or a bat colony roosts in your chimney, you need a solution that’s both effective and humane. Wildlife intrusions in Wyoming peak twice a year: spring denning season (April–June) when mothers seek safe places to birth young, and fall (September–November) when animals look for warm winter shelter. This guide covers everything you need to know about identifying, removing, and preventing nuisance wildlife in the Equality State.

Professional attic inspection for wildlife damage in a Wyoming home.
Who This Is For
This guide is written for Wyoming homeowners, property managers, and landlords who are dealing with or want to prevent nuisance wildlife. Whether you’re in Cheyenne, Casper, Laramie, or a rural ranch, the principles are the same—but the species and regulations may differ. If you’ve heard scratching in the walls, found droppings in the attic, or noticed damage to your home’s exterior, this is your resource.
The Problem
Nuisance wildlife in Wyoming includes raccoons, squirrels, opossums, skunks, and bats. These animals are not malicious—they’re simply seeking food, water, and shelter. Unfortunately, your home provides all three. Attics offer warm, dry spaces ideal for nesting. Chimneys mimic hollow trees (a favorite for raccoons and chimney swifts). Crawlspaces and decks become dens for skunks and opossums. Once inside, animals cause damage: gnawed wires, torn insulation, contaminated droppings, and structural harm from digging and scratching. The problem escalates quickly. A single squirrel can shred attic insulation in one night. A raccoon can tear through a roof vent in minutes. And because wildlife reproduces fast—squirrels have two litters per year, raccoons one—a small issue can become a colony within months. The longer you wait, the more expensive and complex the removal becomes.
Warning Signs
- •Scratching, scurrying, or thumping sounds in the attic or walls, especially at dawn and dusk.
- •Droppings (scat) in the attic, near entry points, or on the ground along the foundation.
- •Gnaw marks on wood, wires, or plastic; shredded insulation or ductwork.
- •Strong, musty odors from urine or feces, especially with raccoons or skunks.
- •Visible damage to soffits, fascia, roof vents, or chimney caps.
- •Tracks or trails in dirt or snow leading to a crawlspace or under a deck.
- •Dead animals or foul smells from a trapped animal in a wall or chimney.
Risks of Waiting
- ⚠Structural damage: Animals gnaw through wood, drywall, and electrical wiring, increasing fire risk.
- ⚠Health hazards: Droppings and urine can spread histoplasmosis (bats), leptospirosis (raccoons), and hantavirus (rodents).
- ⚠Secondary infestations: Untreated wildlife attract fleas, ticks, and mites that can invade your home.
- ⚠Higher costs: A simple exclusion job can turn into a $2,500+ restoration if damage worsens.
- ⚠Legal trouble: Wyoming law restricts how and when you can remove certain species; trapping without a license may be illegal.

Treatment Options
Humane Live Trapping & Removal
$250–$600independent pest-control providers set humane traps to capture and relocate animals. Traps are checked daily. After removal, access points are temporarily sealed to prevent re-entry while animals are removed.
Exclusion & Prevention (One-Way Doors & Sealing)
$800–$2,500Permanent solution that seals all entry points after animals are excluded using one-way doors or eviction fluids. Includes repairing damaged vents, capping chimneys, and reinforcing soffits. Guaranteed work.
Bat Colony Exclusion
$500–$1,500Specialized process for bat infestations. Technicians install one-way exclusion devices (bat cones) over entry points. Bats can leave but cannot re-enter. After all bats are out, the openings are permanently sealed. All work complies with state regulations for protected bat species.
Understanding Wyoming Wildlife Laws and Protected Species
Wyoming’s wildlife is managed by the Wyoming Game and Fish Department. Many common nuisance species, like raccoons and skunks, are classified as furbearers and may be trapped only during specific seasons or with a permit. Bats are protected; it is illegal to kill them or exclude them during maternity season (May 1–July 31) in most areas. Opossums are not native to Wyoming but have been introduced; they are not protected but still require humane treatment. Professional wildlife control operators are licensed by the state and trained to handle all species legally. Attempting DIY removal without understanding local regulations can result in fines. Always verify that your service provider carries the required licenses and liability insurance.
The Science of Humane Exclusion: Why Trapping Alone Fails
Many homeowners assume that trapping and removing an animal solves the problem. In reality, trapping is only half the job. Wildlife operates on the principle of the 'vacuum effect': if you remove an animal without sealing the entry point, another will soon move in to claim the territory. Humane exclusion uses a combination of one-way doors, eviction fluids (for raccoons), and physical sealing to ensure animals leave and cannot return. One-way doors are placed over entry points; animals push out but cannot push back in. After a few days, the doors are removed and the hole is permanently sealed. This method is more effective than trapping because it removes entire families (including young that might be hidden) and prevents future intrusions. In Wyoming’s climate, where animals desperately seek warmth in winter, exclusion is the only sustainable solution.
Common Entry Points and How to Inspect Them
Wyoming homes face unique challenges due to extreme weather. Freeze-thaw cycles can loosen siding and create gaps. The most common entry points are: roof vents (plastic or metal covers that can be pried open), soffit intersections (especially where rooflines change angle), chimney crowns (unprotected tops), and crawlspace vents (often missing screens). Also check: gaps where utility lines enter the house, loose or missing weatherstripping under doors, and rotted wood around windows. Use a flashlight at night to look for light shining through gaps. Listen for scratching at dawn and dusk. Professionals use ladders and inspection cameras to find hidden entries. A thorough inspection takes 30–60 minutes and is offered free by our company.
Health Risks from Wildlife Intrusion: What You Need to Know
Wildlife in your home is more than a nuisance—it’s a health hazard. Raccoon droppings can contain raccoon roundworm (Baylisascaris), which is dangerous to humans, especially children. Bat guano (droppings) can harbor histoplasma capsulatum, a fungus that causes histoplasmosis, a lung infection. Skunk spray, while not toxic, can cause nausea and temporary blindness if it gets in eyes. Squirrels and rodents can carry hantavirus, which is transmitted through urine and droppings. Additionally, wildlife often bring fleas, ticks, and mites into your home. These parasites can bite humans and pets, spreading diseases like Lyme disease and Rocky Mountain spotted fever. If you find droppings, do not sweep or vacuum—this aerosolizes pathogens. Instead, call a professional for safe cleanup and disinfection.
Seasonal Wildlife Behavior in Wyoming: When to Act
Wyoming’s wildlife patterns are driven by harsh winters and short summers. In spring (April–June), pregnant females seek safe, warm dens. This is peak time for raccoons and squirrels to enter attics. By summer (July–August), young are growing and become noisy—homeowners often first notice sounds then. Fall (September–November) is a second peak: animals that failed to find natural dens try to get into homes before snow. Bats enter hibernation in late fall, so fall exclusion is critical to prevent them from overwintering. Winter (December–March) is quieter, but animals already inside remain active. If you hear noises in winter, it likely means an established infestation. Timing matters: exclusion must be done before maternity season for bats, and trapping is most effective in early spring before young are born. A professional can advise the best time for your specific situation.

When to Call a Professional
Call a professional immediately if you hear consistent noises in your attic or walls, see droppings or damage, or smell a strong animal odor. Do not attempt to trap or handle wildlife yourself—Wyoming law often requires a license, and you risk injury or disease. If you have bats, contact a pro right away: bat exclusion must be done outside of maternity season (May–July) to avoid trapping flightless babies. Call 888-546-7983 for a inspection terms that vary by provider.
DIY vs Professional
DIY wildlife control is tempting but rarely effective. Store-bought traps are often too small or inhumane, and relocating animals without a permit is illegal in many Wyoming counties. Worse, sealing an animal inside your home—by blocking the only exit—can lead to death and decay inside your walls. Professionals understand animal behavior, know local laws, and use exclusion techniques that prevent re-infestation. The up-front cost of a pro may be higher, but it saves you from repeated damage and health risks. For simple prevention like sealing cracks and trimming trees, you can DIY. But for active infestations, hire a licensed wildlife control operator.
Local Context
Wyoming’s wildlife control needs vary by region. In the southeastern corner, around Cheyenne and Laramie, raccoons and squirrels are the top nuisance animals, thanks to urban green spaces and older homes with accessible attics. In the central and western parts of the state—Casper, Riverton, Rock Springs—skunks and bats are more common, drawn to crawlspaces and outbuildings. The mountainous regions near Jackson and Cody see occasional black bear intrusions, though these are less frequent and require specialized handling. Elevation also plays a role: homes at higher elevations (above 6,000 feet) are more likely to have bat colonies due to cooler attic temperatures that mimic caves. Regardless of location, all Wyoming homeowners should prioritize exclusion before winter. The state’s long, cold season means animals that breach your home in fall will stay until spring, causing months of damage. Our inspection terms that vary by provider cover all Wyoming counties, and we dispatch local technicians who know the regional species and regulations.
Prevention Tips
- ✓Seal all gaps larger than 1/4 inch around pipes, vents, and eaves with heavy-gauge steel mesh or caulk.
- ✓Install chimney caps and cover attic vents with corrosion-resistant screening.
- ✓Trim tree branches at least 10 feet from your roofline to prevent squirrel and raccoon access.
- ✓Secure garbage cans with locking lids and store pet food indoors.
- ✓Remove bird feeders or place them far from the house; they attract rodents and larger wildlife.
- ✓Inspect your roofline, soffits, and foundation twice a year (spring and fall) for damage.
- ✓Keep crawlspaces and basements dry and sealed; animals seek water as well as shelter.
💡 Did You Know?
- ★Opossums are largely immune to most snake venom and eat thousands of ticks per season, making them beneficial in small numbers.
- ★Squirrels plant thousands of trees a year by forgetting where they bury nuts, contributing to forest regeneration.
- ★Raccoons have extremely dexterous front paws with four to five times more sensory receptors than human hands, allowing them to open latches and jars.
