Who This Is For
This page is for Montana homeowners, property managers, and landlords who are dealing with—or want to prevent—nuisance wildlife. Whether you’ve heard scratching in the attic, found droppings in the garage, or noticed holes in your siding, you’ll find practical, expert advice here.
The Problem
Montana’s diverse landscape—from the Rocky Mountains to the Great Plains—means a wide variety of wildlife lives close to human development. Raccoons, squirrels, opossums, skunks, and bats are the most common culprits. They enter through small gaps in roofs, chimneys, vents, and foundations, often during spring birthing season or when fall temperatures drop. Once inside, they can cause significant damage: chewed wires, torn insulation, contaminated attic spaces, and structural damage from gnawing and nesting. Worse, they carry diseases like rabies, leptospirosis, and histoplasmosis (from bat guano).
Warning Signs
- •Scratching, scurrying, or thumping sounds in the attic or walls, especially at night.
- •Droppings (scat) near entry points or in attic spaces; bat guano piles under roosts.
- •Gnaw marks on wood, wires, or plastic; holes in siding or soffits.
- •Strong odors from urine, feces, or dead animals (e.g., skunk spray).
- •Visible tracks or rub marks on walls, ducts, or insulation.
- •Damaged vents, loose shingles, or chimney caps displaced.
- •Pet or human encounters with wildlife on the property (e.g., raccoons at trash cans).
Risks of Waiting
- ⚠Structural damage from gnawing and nesting can lead to costly repairs.
- ⚠Fire hazard from chewed electrical wires.
- ⚠Health risks from diseases carried by wildlife and their droppings.
- ⚠Secondary infestations of insects attracted to carcasses or droppings.
- ⚠Legal issues if protected species are harmed or if exclusion is done incorrectly.

Treatment Options
Humane Live Trapping and Removal
$250–$600independent pest-control providers set cage traps baited with food attractants. Trapped animals are humanely euthanized or relocated per Montana regulations. This is typically used for raccoons, skunks, and opossums.
Exclusion and Sealing
$800–$2,500All entry points are identified and sealed with heavy-gauge steel mesh, caulking, or sheet metal. One-way doors allow animals to exit but not re-enter. This is the only permanent solution.
Bat Exclusion and Guano Cleanup
$500–$2,000Specialized exclusion using netting or tubes that allow bats to leave but not return. Attic cleanup and guano removal are often required to eliminate health hazards.
Montana’s Protected Species and Regulations
Montana Fish, Wildlife & Parks (FWP) regulates wildlife control. Many species, including bats, are protected by state law. Raccoons, skunks, and opossums are classified as furbearers and may be trapped only during specific seasons unless they are causing damage. Bats cannot be killed or trapped during maternity season (June–August). Professional wildlife control operators must hold a nuisance wildlife control permit from FWP. This ensures animals are handled humanely and according to the law. Homeowners attempting DIY removal may inadvertently violate regulations, leading to fines. Always verify that your wildlife control company is licensed and follows FWP guidelines.
Why Humane Exclusion Is the Gold Standard
Trapping and removing a raccoon or squirrel may provide short-term relief, but if entry points remain open, new animals will move in. Humane exclusion focuses on sealing all potential entry points after ensuring no animals are trapped inside. This is done by installing one-way doors, mesh, and covers that allow animals to exit but not re-enter. Exclusion is more thorough and cost-effective over time. It also prevents orphaned young from dying in the attic, which creates odor and fly problems. Professional exclusion includes a thorough inspection of the entire structure, using sealants and materials that withstand Montana’s weather extremes.
Seasonal Patterns in Montana Wildlife Intrusions
Spring and fall are the peak seasons for wildlife intrusions in Montana. In spring, females seek safe, warm places to give birth and raise young. Attics, chimneys, and crawlspaces become ideal nurseries. In fall, animals search for winter shelter as temperatures drop. This is when you’re most likely to hear scratching or see animals entering your home. Winter can be quieter, but if animals have already taken up residence, they will remain active. Summer is the busiest time for bat exclusion, as bats are active and can be excluded without harming young. Understanding these patterns helps homeowners anticipate and prevent problems.
Health Risks from Wildlife Infestations
Wildlife in the home pose serious health risks. Raccoon and skunk droppings can contain raccoon roundworm (Baylisascaris) and leptospirosis, which are harmful to humans and pets. Bat guano can harbor Histoplasma capsulatum, a fungus that causes histoplasmosis, a respiratory disease. Bats are also the primary vector for rabies in Montana. Squirrels and rats can introduce fleas and ticks. Dead animals in walls or attics attract flies and beetles. Prompt professional cleanup and disinfection are essential to mitigate these risks. The CDC recommends professional removal and decontamination for any significant wildlife intrusion.
DIY vs. Professional Wildlife Control in Montana
| Factor | DIY | Professional |
|---|---|---|
| Cost | Low upfront, high risk of repeat damage | $250–$2,500, permanent solution |
| Regulation compliance | Easy to violate state laws | Fully licensed and permitted |
| Effectiveness | Temporary; rarely removes all animals | Permanent exclusion guaranteed |
| Health safety | High risk of disease exposure | Proper PPE and decontamination |
| Time commitment | Hours to weeks of trial and error | 1–3 days for most jobs |
What Affects Cost
- ✓Species of animal (bats and raccoons often cost more due to regulations and complexity).
- ✓Number of animals and size of infestation.
- ✓Location of entry points (roof vs. ground level affects labor).
- ✓Extent of damage and need for restoration (insulation replacement, guano cleanup).
- ✓Structural complexity of the building (multiple stories, difficult access).
- ✓Local labor rates and travel distance (rural Montana may have higher travel fees).
- ✓Time of year (spring and fall are busier, potentially higher demand).

When to Call a Professional
If you hear persistent noises in the attic, find droppings, or see animals entering your home, call a professional immediately. Also call if you suspect a bat colony (bats are protected and require special exclusion windows), if you smell dead animal odors, or if you’ve tried DIY methods that failed. Montana regulations require independent pest-control providers for many species, and improper handling can harm you and the animal.
DIY vs Professional
DIY wildlife control often fails because homeowners can’t find all entry points or use methods that don’t comply with state laws. Live traps alone are ineffective long-term; animals will return or new ones will enter. Professionals have the training, equipment, and knowledge of Montana regulations to ensure humane, legal, and permanent results. While DIY exclusion may work for a single squirrel, most infestations require professional assessment. The cost of professional service is often less than the damage caused by a repeat infestation.
Local Context
Montana’s geography creates varied wildlife control challenges. In the western mountains (Missoula, Kalispell, Bozeman), bats and squirrels are common due to forest proximity. The eastern plains (Billings, Miles City) see more raccoons, skunks, and opossums. Urban areas like Great Falls and Helena have high raccoon populations attracted to trash. Rural properties face issues with ground squirrels and prairie dogs burrowing under foundations. Climate also plays a role: cold winters drive animals into structures, while hot summers push them into attics for cooling. Regardless of location, professional wildlife control is available statewide, with inspection terms that vary by provider and service guarantees.
Prevention Tips
- ✓Seal all gaps larger than ¼ inch in siding, soffits, and roof edges with steel mesh or caulking.
- ✓Install chimney caps and vent covers with heavy-gauge mesh.
- ✓Trim tree branches away from the roof to limit access.
- ✓Secure trash cans with locking lids; store pet food indoors.
- ✓Remove bird feeders and fallen fruit that attract wildlife.
- ✓Inspect your attic and crawlspace annually for signs of entry.
- ✓Keep doors and windows closed, especially at dusk when bats are active.
💡 Did You Know?
- ★Opossums are largely immune to most snake venom and eat thousands of ticks per season, helping control tick-borne diseases.
- ★Squirrels plant thousands of trees a year by forgetting where they bury nuts, contributing to forest regeneration.
- ★A single bat can eat up to 1,000 mosquitoes per hour, but a colony in your attic can produce guano that harbors harmful fungi.
