Who This Is For
This guide is written for Tennessee homeowners, property managers, and landlords who are hearing scratching in the attic, finding droppings near eaves, or noticing chewed entry points. If you suspect a squirrel infestation, you need actionable, expert advice on removal and prevention.
The Problem
squirrels are rodents with incisors that never stop growing. To keep them filed down, they gnaw on almost anything, including structural wood, drywall, and electrical cables. In Tennessee, the eastern gray squirrel (Sciurus carolinensis) is the most common attic invader, though fox squirrels and southern flying squirrels also cause problems. These animals can squeeze through gaps as small as 1.5 inches—about the size of a golf ball—making seemingly minor exterior damage a potential entry point.
Warning Signs
- •Scratching or scurrying noises in the attic, especially at dawn and dusk.
- •Droppings that resemble small, dark pellets, often found near entry points or in insulation.
- •Chewed soffits, fascia boards, or vent screens with visible teeth marks.
- •Nests made of shredded insulation, leaves, and twigs in attic corners.
- •Foul odors from urine and feces accumulation, sometimes attracting flies.
- •Sightings of squirrels entering gaps under eaves or through roof vents.
- •Damage to bird feeders or garden plants, indicating a nearby squirrel population.
Risks of Waiting
- ⚠Electrical fires from gnawed wiring: squirrels chew through insulation, exposing live wires.
- ⚠Structural damage: Repeated gnawing weakens wooden beams and drywall.
- ⚠Health hazards: Urine and feces can contain leptospirosis and salmonella; dried droppings can become airborne.
- ⚠Secondary infestations: Unsealed entry points allow other pests (bats, raccoons, mice) to enter.
- ⚠Increased exclusion costs: Delaying repairs leads to larger holes and more complex damage, raising costs.

Treatment Options
One-Way Exclusion Doors
$200–$400Humane doors that allow squirrels to exit but not re-enter. Typically left in place for 7–10 days to ensure all animals leave.
Full Exclusion & Sealing
$500–$1,500Sealing all gaps >1/4 inch with heavy-gauge mesh, steel wool, or caulk. Includes repairing chewed wood and vent screens.
Trapping and Relocation
$300–$600Live-trapping followed by relocation (less common now due to stress on animals and legal restrictions). Only recommended in specific situations.
Understanding Squirrel Behavior and Breeding Cycles
Tennessee’s eastern gray squirrels breed twice a year: once in late winter (January–February) and again in late summer (July–August). Gestation lasts about 44 days, and litters average 2–4 young. Mothers seek warm, dry, protected spaces for their nests—your attic qualifies perfectly. This biological drive is why infestations peak in spring and fall. After the young are weaned (around 10–12 weeks), they often remain in the attic or create new entry points. Understanding this cycle helps time exclusion efforts: avoid sealing animals in during breeding season; instead, use one-way doors to let them out naturally.
Fire and Structural Risks from Squirrel Gnawing
squirrels must gnaw continuously to keep their incisors from overgrowing. In an attic, they target wood beams, drywall, and—most dangerously—electrical wiring. The National Pest Management Association estimates that rodents cause 20% of undetermined electrical fires in the U.S. each year. In Tennessee, several house fires have been linked to squirrel-chewed wiring. Additionally, squirrels shred insulation for nesting, reducing your home’s energy efficiency. Moisture from urine can also lead to mold growth, compounding health risks. Professional exclusion and wiring inspection are critical after an infestation.
Legal and Ethical Considerations in Tennessee
In Tennessee, squirrels are classified as game animals, but they can be trapped without a permit if causing damage to property. However, relocation is strongly discouraged because it often leads to the animal’s death due to unfamiliar territory. Humane exclusion—allowing animals to leave on their own—is the preferred method. The Tennessee Wildlife Resources Agency (TWRA) recommends sealing entry points after ensuring no animals are trapped inside. Always check local ordinances; some cities may have additional restrictions. Using a licensed wildlife control operator ensures compliance with state regulations.
How Tennessee Properties Should Prepare for squirrel Service
Before a professional visit in Tennessee, 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 Tennessee squirrel Problems Different
Tennessee 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.
Squirrel Removal Methods Comparison

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 hidden entry points or fail to seal gaps correctly, leading to re-infestation. A licensed wildlife control operator can perform a thorough inspection, install one-way exclusion doors, and seal all potential entry points with durable materials.
DIY vs Professional
DIY exclusion may work for very small, single-entry situations if you are comfortable on a ladder and have the right materials (heavy-gauge steel mesh, caulk, foam). However, most homeowners lack the experience to identify all possible entry points—especially those hidden behind siding or under eaves. Professionals use specialized tools, ladders, and sealing products that last longer. They also offer guarantees: if the problem returns within a year, they fix it at no extra cost. Given the fire risk from chewed wiring, the peace of mind from a professional inspection is often worth the investment.
Local Context
Tennessee’s diverse geography means squirrel problems vary by region. In eastern Tennessee (Knoxville, Chattanooga, Tri-Cities), dense forests and the Appalachian foothills support large populations of gray squirrels. Homes near woodland edges are especially vulnerable. In middle Tennessee (Nashville, Murfreesboro), suburban development blends with wooded areas, creating prime squirrel habitat. Attics in older homes with soffit gaps are common targets. Western Tennessee (Memphis, Jackson) has more fox squirrels, which are larger and can cause more damage. The warmer climate also extends the active season slightly. Regardless of region, the same principles apply: inspect, exclude, and prevent.
Prevention Tips
- ✓Trim tree branches to at least 10 feet from the roofline to limit jumping access.
- ✓Install metal flashing or baffles on poles and downspouts to prevent climbing.
- ✓Seal all exterior gaps larger than 1/4 inch with silicone caulk, steel wool, or copper mesh.
- ✓Cover attic vents, soffits, and gable ends with heavy-gauge hardware cloth (1/4-inch mesh).
- ✓Remove bird feeders or place them on squirrel-proof poles at least 15 feet from the house.
- ✓Secure garbage cans with tight lids and clean up fallen nuts or fruits from the yard.
- ✓Inspect the roofline annually for loose shingles, damaged fascia, or gaps near eaves.
