Who This Is For
This guide is for Montana homeowners, property managers, and landlords dealing with squirrel intrusions. Whether you're in a rural area near the Rockies or a city like Great Falls, the strategies here apply. If you hear scratching in your attic, see droppings, or notice chewed entry points, this page will help you decide on the best course of action.
The Problem
squirrels are relentless chewers. Their incisors grow continuously, so they gnaw on wood, drywall, and even electrical wires to keep them trimmed. This gnawing can strip insulation from wiring, leading to short circuits and attic fires—a risk highlighted by the National Fire Protection Association. In Montana, where winters are harsh, squirrels often seek shelter in attics and wall voids. They enter through gaps as small as 1.5 inches—about the width of a credit card—making seemingly minor exterior damage a potential entry point.
Warning Signs
- •Scratching or scampering sounds in the attic, especially at dawn and dusk.
- •Droppings that are oblong, about 3/8 inch long, often near entry points.
- •Chewed holes in soffits, fascia boards, or roof edges.
- •Nesting materials (leaves, twigs, insulation) visible near vents or eaves.
- •Squirrel sightings on the roof or near utility lines entering your home.
- •Strange odors from urine or decomposing carcasses if a squirrel becomes trapped.
- •Damaged bird feeders or garden plants—a sign of high squirrel activity nearby.
Risks of Waiting
- ⚠Electrical fires from gnawed wiring—a leading cause of attic fires.
- ⚠Structural damage to wood beams, drywall, and insulation.
- ⚠Secondary infestations of fleas, mites, or ticks carried by squirrels.
- ⚠Health risks from droppings and urine (e.g., leptospirosis, salmonella).
- ⚠Higher repair costs as damage compounds over time.

Treatment Options
One-Way Exclusion Doors
$250–$500A humane device placed over the main entry hole that allows squirrels to exit but not re-enter. All other entry points are sealed beforehand to prevent re-entry elsewhere. Standard for attic evictions.
Full Exclusion & Repair
$500–$1,500Includes sealing all gaps (≥1.5 inches) with heavy-duty materials like galvanized steel mesh, repairing chewed wood and soffits, and cleaning/decontaminating the attic. Often bundled with removal.
Trapping and Relocation
$150–$400 per squirrelLive trapping using cage traps baited with nuts or peanut butter. Rarely recommended without exclusion because it doesn't address the root cause. Some Montana municipalities restrict relocation to prevent disease spread.
Why squirrels Invade Montana Attics
Montana's climate features cold winters and hot summers, making attics attractive for temperature regulation. squirrels breed twice a year: a first litter born in early spring (February–April) and a second in late summer (August–September). During these periods, pregnant females seek warm, dry, and protected spaces to raise their young. Attics often provide the perfect nursery, with insulation for bedding and proximity to food sources like bird feeders or gardens. Once inside, squirrels build nests out of shredded insulation, leaves, and other debris. They also use attics as winter shelter, entering in late fall to escape freezing temperatures. The dry, stable environment of an attic is far superior to a tree cavity, especially during Montana's harsh winters. Understanding this seasonal pattern helps homeowners time inspections and preventive measures effectively.
The Fire Hazard of Gnawed Wiring
squirrels' incisors grow about 6 inches per year, so they must constantly gnaw to keep them worn down. Electrical wires are a common target because the plastic insulation resembles the texture of tree bark. This gnawing can strip the insulation, exposing copper conductors. If those conductors come into contact with flammable materials like dust, wood, or insulation, a short circuit can ignite a fire. According to the National Fire Protection Association, rodents (including squirrels) are responsible for an estimated 20,000 structure fires annually in the U.S. In Montana, several attic fires have been traced to squirrel damage. Professional exclusion not only removes the animals but also identifies and repairs compromised wiring, reducing this risk significantly.
Humane Removal: One-Way Exclusion Doors
The most humane and effective method for removing squirrels from an attic is the one-way exclusion door. This device fits over the main entry hole and allows squirrels to exit but not re-enter. Before installation, all other potential entry points are sealed (except the main hole) to prevent re-entry elsewhere. The door is left in place for several days until it's clear all squirrels have left. This method is preferred over trapping and relocation because it keeps families together (babies are often left behind if not accounted for) and avoids the stress of relocation, which often leads to the squirrel's death in unfamiliar territory. Professionals time the process to avoid separating mothers from young, usually waiting until the breeding season ends or checking for babies. The service guarantee from Squirrel Removal ensures that if any squirrel re-enters, they will return at no extra charge.
How Montana Properties Should Prepare for squirrel Service
Before a professional visit in Montana, clear access to baseboards, utility areas, kitchens, bathrooms, garages, crawl spaces, and any location where activity has been seen. Take photos of sightings, save damaged materials when safe, and note when the problem is most active. This helps the technician confirm the species, find nesting or entry points, and choose a treatment plan that matches the property instead of relying on a generic spray-and-leave visit.
Questions to Ask Before Booking squirrel Control
Ask whether the inspection is included, what treatment methods are being proposed, how follow-up visits are handled, and what conditions could change the price. For rental properties, restaurants, hotels, warehouses, and multi-unit buildings, ask whether documentation is provided after service. Strong providers explain the source of the problem, the treatment area, safety instructions, and prevention steps in plain language before work begins.
What Makes Montana squirrel Problems Different
Montana properties can have different pest pressure from block to block because of building age, landscaping, moisture, trash handling, nearby food sources, and how tightly entry points are sealed. A good inspection does not assume every property needs the same service. It checks the structure, surrounding conditions, activity level, and safety needs before recommending treatment.
Inspection Steps for squirrel Issues
A complete inspection should look at interior activity, exterior entry points, moisture conditions, food or harborage sources, nearby vegetation, storage areas, and any connected units or shared walls. The best inspection notes where activity is confirmed, where it is suspected, and what needs to change after treatment so the same issue does not return quickly.
Follow-Up and Prevention Plan
Professional pest control should not stop at one visit when the infestation risk is ongoing. Follow-up timing depends on the pest, severity, season, property type, and whether sanitation or exclusion work is still needed. A practical prevention plan may include sealing entry points, improving drainage, trimming vegetation, changing storage habits, and monitoring activity after service.
Removal Method Comparison

|---|---|---|---|
| One-way exclusion door | Active attic infestation | $250–$500 | High |
| Trapping & relocation | Isolated squirrel inside | $150–$400 per squirrel | Low–Medium |
| Full exclusion + repair | Multiple entry points or damage | $500–$1,500 | High |
What Affects Cost
- ✓Number of entry points to seal (more points = higher cost).
- ✓Roof pitch and accessibility (steep roofs require special equipment).
- ✓Extent of damage to wood, wiring, and insulation.
- ✓Number of squirrels (larger litters require more exclusion doors).
- ✓Season (winter ice and snow can complicate sealing work).
- ✓Local labor rates—urban areas like Bozeman may cost more than rural regions.
- ✓Need for attic cleanup and decontamination (biohazard handling).

When to Call a Professional
If you hear persistent scratching, see droppings, or notice chewed entry points, call a professional immediately. DIY attempts often miss secondary entry points, leading to trapped squirrels that die in walls and cause odor problems. Professionals use infrared cameras and sealant materials that last. Squirrel Removal offers inspection terms that vary by provider—call +1 888 546 7983 to schedule.
DIY vs Professional
DIY squirrel control might involve setting a live trap or patching a hole with caulk. However, squirrels are adept at finding alternative entry points. Without a thorough inspection, you risk sealing a squirrel inside, which can lead to a dead animal in your wall. Professionals use one-way exclusion doors and galvanized steel mesh that squirrels cannot chew through. For most Montana homeowners, the cost of professional exclusion pays for itself by preventing future damage.
Local Context
Montana's squirrel species include the eastern gray squirrel, fox squirrel, and red squirrel, with gray squirrels being the most common attic invaders. In western Montana (Missoula, Kalispell), dense forests provide ample outdoor habitat, but urban development pushes squirrels into attics. In eastern Montana (Billings, Miles City), agricultural landscapes and sparse trees lead squirrels to seek shelter in homes more readily. Climate plays a role: the colder winters in Great Falls and Helena increase the urgency for squirrels to find warm shelter. In milder areas like the Bitterroot Valley, attic invasions may occur year-round. Top metros include Billings (largest city), Missoula, Great Falls, Bozeman, and Butte, each with varying levels of squirrel activity. Homeowners in Bozeman's newer developments often face conflicts due to construction near natural habitats. Squirrel Removal serves all of Montana with inspection terms that vary by provider.

Prevention Tips
- ✓Trim tree branches to at least 10 feet from your roofline to limit jumping access.
- ✓Inspect your attic regularly for signs of nesting or droppings.
- ✓Seal all gaps larger than 1/4 inch with caulk or steel wool (squirrels can gnaw through foam).
- ✓Install metal flashing or mesh over vents, chimneys, and soffit openings.
- ✓Keep bird feeders away from the house and clean up fallen seeds.
- ✓Secure garbage cans with tight-fitting lids.
- ✓Consider squirrel-proof bird feeders with weight-sensitive perches.
💡 Did You Know?
- ★squirrels use elaborate fake-burying tactics—they dig a hole, pretend to drop a nut, then cover it up to fool onlookers, while actually hiding the nut elsewhere.
- ★squirrels can rotate their ankles 180 degrees, allowing them to climb down trees headfirst by gripping bark with their rear paws pointing backward.
- ★The eastern gray squirrel has a memory that helps it relocate thousands of cached nuts by using spatial landmarks and even memory of the nut's quality.
