Tennessee’s rich forests, rolling hills, and mild climate provide an inviting environment for diverse wildlife. While these natural surroundings contribute to the state’s beauty, they also increase the chances of unwanted encounters with wildlife pests. From raccoons rummaging through garbage to squirrels chewing attic wiring, these animals can quickly turn from fascinating neighbors to frustrating nuisances.
For homeowners, understanding which wildlife pests are most common—and how to prevent them from moving in—is essential. Taking action early can help you avoid costly property damage, health risks, and repeated infestations.
The Most Common Wildlife Pests in Tennessee
1. Raccoons
Raccoons are notorious scavengers. Drawn to garbage cans, compost piles, and pet food, they often invade neighborhoods in search of an easy meal. In homes, raccoons may nest in attics, leaving behind urine and feces that can cause odors and potential health issues. They are also known carriers of rabies and roundworm.
2. Squirrels
Squirrels are charming when scampering across trees, but when they invade attics, they create serious problems. They chew through wood, insulation, and electrical wires, raising fire hazards. During colder months, attics provide them warmth and shelter, making entry prevention critical.
3. Skunks
Skunks often seek shelter beneath decks, sheds, or crawlspaces. While their defensive spray is their most obvious threat, skunks can also dig holes in yards while hunting insects and grubs. They may carry diseases such as rabies and are capable of spreading parasites like fleas and ticks.
4. Opossums
Opossums are scavengers that feed on nearly anything, from garbage to small animals. Although generally not aggressive, they can spread diseases and introduce parasites into your yard or home. They frequently den under porches and sheds, creating messes with their foraging.
5. Bats
Bats play an important ecological role by controlling insect populations. However, when they roost inside attics, they create serious problems. Bat droppings (guano) can harbor histoplasmosis spores, a dangerous respiratory disease. Removing bats requires careful, humane exclusion.
6. Birds
Certain birds, such as pigeons and starlings, can create problems when nesting in vents, chimneys, or eaves. Their droppings corrode building materials, spread disease, and attract insects. In large numbers, they can cause extensive property damage.
7. Snakes
While most snakes in Tennessee are non-venomous and helpful for rodent control, venomous species like copperheads and timber rattlesnakes pose risks near homes. Snakes often take advantage of cluttered yards or rodent infestations that provide easy food sources.
How Wildlife Pests Impact Homes and Health
Wildlife infestations aren’t just inconvenient—they can cause long-term damage and pose health risks. Some of the most common issues include:
-
Structural Damage: Chewing, digging, and nesting weaken wood, siding, insulation, and roofing.
-
Electrical Hazards: Rodents and squirrels gnaw wires, increasing fire risk.
-
Odors and Contamination: Urine, feces, and nesting materials contaminate air and surfaces.
-
Parasites and Disease: Fleas, ticks, mites, and diseases like rabies or histoplasmosis are frequently linked to wildlife.
-
Food Contamination: Wildlife can access pantries or pet food, spreading germs across kitchens and storage areas.
Left unchecked, these problems often escalate—costing homeowners thousands of dollars in repairs and posing risks to family health.
Why Tennessee Homes Are So Vulnerable
Several factors make Tennessee homes particularly susceptible to wildlife intrusions:
-
Abundant Natural Habitats: Forests, rivers, and farmland create ideal conditions for wildlife populations.
-
Seasonal Changes: Cold winters drive animals into homes for warmth, while spring increases breeding and nesting activity.
-
Urban Expansion: As communities grow, wildlife adapts by finding food and shelter in residential areas.
-
Older Housing Stock: Gaps in siding, soffits, vents, and foundations provide easy access points.
Understanding these vulnerabilities is the first step toward prevention.
Practical Prevention Strategies
Keeping wildlife pests out requires a mix of vigilance, property maintenance, and proactive measures. Homeowners can reduce risks by focusing on these key steps:
Seal Entry Points
Inspect your home for cracks, gaps, or holes in siding, roofing, and foundations. Pay close attention to areas around chimneys, vents, and soffits. Use sturdy materials like metal flashing or hardware cloth to close gaps.
Secure Food Sources
Never leave pet food outdoors overnight. Use wildlife-proof garbage cans with tight-fitting lids. If you compost, keep piles well-covered to reduce attraction.
Maintain the Yard
Trim tree branches away from rooftops to reduce squirrel and raccoon access. Keep grass cut short, and remove brush piles that provide cover for snakes and opossums.
Protect Crawlspaces and Decks
Install barriers or latticework around decks and sheds to block skunks and opossums. Repair broken foundation vents promptly.
Bird and Bat Deterrents
Use chimney caps and vent covers to keep birds and bats from roosting inside. Installing bat houses in yards can also encourage bats to settle away from homes while still benefiting from their insect control.
Regular Inspections
Walk around your property seasonally to identify signs of intrusion—droppings, gnawed wood, or strange noises in walls and attics. Early detection prevents major infestations.
Professional Wildlife Control in Tennessee
While prevention is essential, infestations sometimes occur despite a homeowner’s best efforts. Wildlife removal requires specialized skills to ensure safety, compliance with laws, and humane handling of animals.
Professional pest control providers have the expertise to:
-
Identify entry points and nesting areas.
-
Safely remove animals without harming them.
-
Decontaminate and repair damaged areas.
-
Implement long-term exclusion solutions to prevent recurrence.
Attempting to handle wildlife without training can be dangerous and may even violate state regulations. Partnering with a trusted service ensures the problem is resolved fully and responsibly.
