Port Royal is one of the most exclusive waterfront communities in the country. The estates along Gordon Drive and Naples Bay have private docks, direct Gulf access, and meticulously maintained seawalls. That same waterfront lifestyle that makes Port Royal so desirable also makes it a prime habitat for green iguanas. The warm water, lush landscaping, and miles of private seawalls create the perfect environment for iguanas to thrive and burrow.
Why Iguanas Love Port Royal Seawalls
Green iguanas are attracted to seawalls for a simple reason: they need a place to burrow, and the ground behind a seawall is often soft, sandy, and easy to dig. Iguanas dig burrows that can extend 4 to 6 feet deep and several feet wide. They use these burrows for shelter, nesting, and hiding from predators.
The problem is that these burrows undermine the structural integrity of the seawall itself. When an iguana digs a tunnel behind or under a seawall, it removes the soil that supports the wall. Over time, this can cause the seawall to crack, lean, or even collapse. In Port Royal, where seawalls protect multi-million-dollar estates, a compromised seawall is a serious and expensive problem.
Iguanas are also attracted to the vegetation that grows along Port Royal's waterfront. Hibiscus, bougainvillea, orchids, and other ornamental plants are some of their favorite foods. If your waterfront property has lush landscaping, it is essentially an all-you-can-eat buffet for iguanas.
Signs of Iguana Activity on Your Seawall
How do you know if iguanas are already burrowing near your seawall? Here are the most common signs:
- Visible burrow entrances: Look for holes in the ground near the seawall, typically 6 to 12 inches in diameter. These openings may be partially hidden by vegetation.
- Droppings: Iguana droppings are often found near burrow entrances or on seawall caps. They are dark, elongated, and can carry salmonella.
- Sunbathing iguanas: Iguanas bask in the sun on seawall caps, docks, and nearby rocks during the day. If you see iguanas regularly in the same spot, there is likely a burrow nearby.
- Landscaping damage: Chewed or stripped plants, especially hibiscus and orchids, are a clear sign that iguanas are feeding on your property.
- Cracks or settling: If your seawall is developing cracks or the ground behind it is settling, iguana burrows may be the cause.
How to Keep Iguanas Off Your Seawall
1. Remove the Food Source
The first step is to make your property less attractive to iguanas. If you have plants they love, consider replacing them with iguana-resistant alternatives. Plants like milkweed, oleander, and citrus are generally not preferred by iguanas. Removing the food source makes your property less appealing and encourages iguanas to move on.
2. Fill Existing Burrows
Once iguanas are removed, their burrows should be filled to prevent new iguanas from moving in. Fill burrows with sand and topsoil, and compact the ground. If a burrow has undermined the seawall significantly, you may need a structural assessment to determine if repairs are necessary.
3. Install Physical Barriers
Physical barriers can prevent iguanas from accessing the area behind your seawall. Fencing, netting, or mesh installed along the seawall can block iguanas from digging. The barrier should extend below ground level to prevent burrowing underneath it.
4. Professional Removal
If iguanas are already established on your property, prevention alone is not enough. You need professional removal to clear the existing population. Rocky's uses humane, FWC-compliant methods including hand capture, noosing, trapping, and air rifle within state regulations. We remove the iguanas, fill the burrows, and implement prevention to keep them from coming back.
Why Professional Management Matters in Port Royal
Port Royal's waterfront location means that iguana problems can spread quickly from one property to the next. If your neighbor has an iguana infestation, it is only a matter of time before they reach your seawall. Professional management does not just remove the iguanas on your property. It creates a barrier that prevents new iguanas from moving in.
For the private clubs and managed estates in Port Royal, ongoing suppression programs are the most effective approach. Regular site visits, burrow checks, and monitoring keep the entire property clear of iguanas and protect the shared infrastructure, including seawalls, docks, and common areas.
Do Not Wait Until the Seawall Fails
Seawall repair in Port Royal can cost tens of thousands of dollars, and in severe cases, the cost can reach well into six figures given the scale of the waterfront infrastructure. The longer iguanas are allowed to burrow near your seawall, the more damage they cause. Early intervention is always less expensive than waiting for a structural failure.
If you live in Port Royal and have noticed iguanas on or near your seawall, contact Rocky's Cane Toad and Iguana Management. We offer free property inspections and can assess the extent of the problem before it becomes a major expense. Call (239) 922-5992 or request an inspection online.
