Who This Is For
This guide is for Louisiana homeowners, property managers, and landlords dealing with nuisance wildlife. Whether you've spotted a raccoon in your attic, heard scratching in your walls, or found bat droppings in your chimney, this page provides actionable advice tailored to Louisiana's unique climate and wildlife. We'll help you decide when to call a pro and what to expect in terms of cost and process.
The Problem
Wildlife control in Louisiana is a year-round concern, but spring and fall are the peak seasons. In spring, animals like raccoons and squirrels seek safe places to give birth and raise their young. In fall, they look for warm shelter as temperatures drop. Louisiana's humid subtropical climate supports a diverse array of wildlife, including raccoons, squirrels, opossums, skunks, and bats. These animals can squeeze through surprisingly small gaps—squirrels need only a 1.5-inch opening—and once inside, they cause damage to insulation, wiring, and structural components.
Warning Signs
- •Scratching or scurrying sounds in the attic or walls, especially at night (for nocturnal animals like raccoons and opossums) or during dawn/dusk (for squirrels and bats).
- •Droppings near entry points, in attics, or along baseboards. Bat guano accumulates in piles and can harbor histoplasmosis spores.
- •Visible damage: chewed wires, torn insulation, gnawed wood, or holes in soffits, fascia, or roofing.
- •Foul odors from urine, feces, or decomposing animals trapped in walls or chimneys.
- •Tracks or rub marks on walls, insulation, or pipes; raccoons often leave muddy footprints.
- •Nesting materials like shredded paper, leaves, or insulation in attics or crawlspaces.
- •Unusual pet behavior—dogs or cats staring at ceilings, growling, or scratching at walls.
Risks of Waiting
- ⚠Structural damage: rodents chew through wires, increasing fire risk; raccoons can tear ductwork and insulation.
- ⚠Health hazards: wildlife droppings can contain harmful bacteria, parasites, and viruses (e.g., raccoon roundworm, histoplasmosis from bat guano, leptospirosis from urine).
- ⚠Secondary infestations: fleas, ticks, mites, and other parasites can spread from wildlife to pets and humans.
- ⚠Legal issues: protected species like bats and some birds have specific handling rules; improper removal can lead to fines.
- ⚠Increased cost: damage worsens over time, and exclusion becomes more complex and expensive.

Treatment Options
Trapping and Removal
$250-$600Humane live trapping using cage traps baited with appropriate food (e.g., canned fish for raccoons, peanut butter for squirrels). Animals are then relocated or euthanized per state regulations. Trapping alone is not a permanent solution if entry points remain open.
Exclusion (Sealing Entry Points)
$500-$2,500Identifying and sealing all potential entry points with heavy-duty materials like steel mesh, copper mesh, or caulk. One-way doors may be installed to allow animals to exit but not re-enter. This is the only permanent solution.
Damage Restoration and Cleanup
$500-$2,000+Replacing contaminated insulation, repairing chewed wiring, cleaning droppings, and sanitizing affected areas. Often necessary after a prolonged infestation.
Understanding Louisiana's Wildlife Laws
Louisiana wildlife control is regulated by the Louisiana Department of Wildlife and Fisheries (LDWF). Nuisance animals like raccoons, squirrels, and opossums can be trapped and removed without a permit, but relocation is often restricted to prevent disease spread. Bats are protected; you cannot exclude them during maternity season (May–July) without a permit. Some bird species are also protected under the Migratory Bird Treaty Act. Professional operators must be licensed and follow humane guidelines. Homeowners attempting DIY removal should check local ordinances; some cities have specific rules about trapping and relocation.
Common Nuisance Wildlife in Louisiana
Raccoons are the most common problem, known for tearing through roofing and ductwork to den in attics. They carry rabies and raccoon roundworm. Squirrels often enter through small gaps in soffits or fascia, causing damage to wiring and insulation. Opossums are generally less destructive but can take up residence under decks or in crawlspaces; they eat ticks and are resistant to snake venom. Skunks dig under foundations and can spray if threatened. Bats roost in attics and chimneys, leaving guano that can cause histoplasmosis. Each species requires a different approach for effective removal.
The Exclusion Process: Step by Step
Professional exclusion begins with a thorough inspection to identify all entry points. Technicians look for gaps around pipes, vents, eaves, and rooflines. They also check for signs of animal activity like droppings, rub marks, and nest materials. Next, they install one-way doors or traps to remove any animals currently inside. After removal, they seal all entry points with heavy-duty materials: steel mesh for large gaps, copper mesh for small ones, and caulk for cracks. Finally, they clean and sanitize affected areas, replace insulation if needed, and provide a warranty. Exclusion is a long-term solution that prevents future intrusions.
DIY vs Professional Wildlife Control
| Factor | DIY | Professional |
|---|---|---|
| Cost | Low ($0-$100 for materials) | Moderate to high ($250-$2,500) |
| Effectiveness | Often temporary; may miss entry points | Permanent with exclusion and warranty |
| Safety | Risk of bites, diseases, and falls | Trained and insured |
| Legality | May violate local laws for protected species | Licensed and follows regulations |
| Time | Days to weeks with trial and error | Efficient; done in 1-3 days typically |
What Affects Cost
- ✓Type of animal: raccoons and bats often require more complex removal and exclusion due to behavior and regulations.
- ✓Severity of infestation: multiple animals or long-term presence increases labor and materials cost.
- ✓Accessibility: attic or crawlspace entry points that are hard to reach may require more time.
- ✓Structural repairs: damage to roofing, siding, or wiring adds to the total.
- ✓Geographic location: rural areas may have lower rates than urban centers like New Orleans or Baton Rouge.
- ✓Time of year: peak seasons (spring/fall) may see higher demand and prices.
- ✓Permits and regulations: protected species may require additional permits or specialized handling.

When to Call a Professional
You should call a professional wildlife control operator immediately if you suspect an animal is trapped inside walls or a chimney, if you see signs of a large infestation (multiple animals or extensive damage), or if you're dealing with protected species like bats. Professionals have the training, equipment, and permits to handle animals humanely and legally. Attempting DIY removal can be dangerous and ineffective.
DIY vs Professional
DIY wildlife control might work for minor issues like a single squirrel in the attic if you can safely seal the entry point and install a one-way door. However, most homeowners lack the knowledge to identify all entry points, handle protected species, or clean up hazardous droppings safely. Professional exclusion guarantees that the problem is fully resolved. For example, a DIY attempt to seal a raccoon entry might miss secondary gaps, leading to re-entry. Pros also offer warranties and follow state regulations. Given the health risks and potential for property damage, hiring a pro is almost always the better choice.
Local Context
Louisiana's climate varies from humid subtropical in the south to more temperate in the north. This affects wildlife behavior: in coastal areas, nutria and muskrats can be problems near waterways, while in northern parishes, squirrels and raccoons are more common in suburban areas. The state's high humidity also accelerates decay of droppings, increasing health risks from histoplasmosis. Major cities like New Orleans, Baton Rouge, and Shreveport have dense urban wildlife populations. In New Orleans, French Quarter properties often have older architecture with more entry points. Baton Rouge sees many squirrel intrusions due to abundant oak trees. Shreveport's cooler winters drive animals indoors more frequently. Regardless of location, professional help is recommended for safe and legal removal.
Prevention Tips
- ✓Seal all gaps and cracks in your home's exterior with steel wool, copper mesh, or caulk. Pay special attention to eaves, soffits, and rooflines.
- ✓Install chimney caps and vent covers to prevent animals from entering through these openings.
- ✓Trim tree branches that overhang your roof; squirrels and raccoons use them as bridges.
- ✓Secure trash cans with tight-fitting lids and store them in a garage or shed until pickup day.
- ✓Remove bird feeders or place them away from the house; spilled seed attracts rodents and other wildlife.
- ✓Keep attics and crawlspaces clean and dry; avoid storing items that could be used for nesting.
- ✓Inspect your home's foundation and siding for holes or gaps at least twice a year.
💡 Did You Know?
- ★Opossums are largely immune to most snake venom and eat thousands of ticks per season, making them beneficial despite being a nuisance.
- ★Squirrels plant thousands of trees a year by forgetting where they bury nuts, contributing to forest regeneration.
- ★Bats can squeeze through a gap as small as 3/8 inch, making exclusion critical.
