Iguana burrows are not just a nuisance. They are a structural threat that can cause thousands of dollars in damage to your property. Green iguanas dig burrows that can extend 4 to 6 feet deep and several feet wide, often right next to or under critical structures. If you own property in Southwest Florida, understanding the cost of iguana burrow damage is essential.
How Iguana Burrows Cause Damage
Iguanas dig burrows for shelter, nesting, and protection from predators and weather. These burrows are not small holes. A mature iguana burrow can be 6 feet deep and wide enough for a person to crawl into. The problem is where they choose to dig.
Iguanas prefer to dig in soft, sandy soil, which is exactly what you find behind seawalls, under foundations, and along sidewalks in Southwest Florida. When they remove the soil that supports these structures, the ground above begins to settle, crack, and eventually fail.
Types of Iguana Burrow Damage
Seawall Damage
Seawalls are the most common and most expensive casualty of iguana burrowing. When iguanas dig behind or under a seawall, they remove the soil that holds the wall in place. This can cause the seawall to crack, bow, or collapse entirely. In waterfront communities like Cape Coral, Naples, and Fort Myers, seawall failure is a catastrophic event that can flood yards and undermine pool decks and patios.
Foundation Damage
Iguana burrows under foundations and slabs can cause settling and cracking. While less common than seawall damage, foundation damage is far more serious because it affects the structural integrity of your home. Cracks in walls, uneven floors, and sticking doors can all be signs of foundation settling caused by burrowing.
Sidewalk and Driveway Damage
Burrows under concrete sidewalks and driveways cause the concrete to lose its support and crack or sink. This creates trip hazards and requires replacement of the affected sections.
Landscape Destruction
Burrows destroy root systems and kill landscaping. Iguanas also eat a wide variety of ornamental plants, including hibiscus, orchids, fruits, and vegetables. The combination of burrowing and feeding can wipe out years of landscaping investment in a single season.
What Does It Cost to Repair Iguana Burrow Damage?
Repair costs vary widely depending on the type and extent of the damage, the size of the affected area, and the location. Here are general ranges based on the type of repair:
- Seawall repair: Cracking and minor settling can start at several thousand dollars. Full seawall replacement can cost tens of thousands of dollars, depending on the length and height of the wall and the extent of the damage.
- Foundation repair: Foundation crack repair and underpinning can range from several thousand to tens of thousands of dollars, depending on severity. Full foundation replacement is far more expensive.
- Sidewalk and driveway replacement: Replacing cracked or sunken concrete sections typically costs several hundred to several thousand dollars, depending on the area affected.
- Landscaping replacement: Replacing destroyed plants and repairing burrow damage to lawns and garden beds can range from a few hundred to several thousand dollars, depending on the scope.
These are general ranges. The actual cost depends on your specific situation, and the best way to get an accurate estimate is to consult a contractor after the iguanas have been removed and the burrows have been filled.
Prevention Is Far Less Expensive Than Repair
The most important point is this: preventing iguana burrow damage costs a fraction of what it costs to repair the damage. A professional removal and prevention program is an investment that protects your property from damage that can run into the tens of thousands of dollars.
Effective prevention includes:
- Professional removal: Clearing existing iguanas from your property using humane, FWC-compliant methods.
- Burrow filling: Filling existing burrows with compacted sand and soil to prevent new iguanas from moving in.
- Barrier installation: Installing physical barriers in high-risk areas to prevent future burrowing.
- Regular monitoring: For waterfront properties and HOAs, ongoing monitoring catches new burrows before they cause damage.
- Landscaping changes: Replacing iguana-preferred plants with resistant varieties reduces the attraction.
Do Not Wait for the Damage to Get Worse
If you have noticed iguana burrows on your property, the damage is already happening. Every day that the burrows remain active, the structural damage gets worse. The cost of removal and prevention today is far less than the cost of repairing a collapsed seawall or cracked foundation next year.
