Can iguanas damage your home?

Answered by Stephen Mosley

Digging and tunneling iguanas can indeed pose a threat to the structural integrity of your home. These reptiles have a natural instinct to create nesting burrows, which often result in the formation of “D” shaped holes and extensive underground tunnels. These tunnels can stretch up to 80+ feet in length, extending beneath and around your property.

One of the major concerns with iguana burrows is the potential for accelerated erosion. As these tunnels are created, they can disrupt the soil composition and drainage patterns, leading to increased water flow and erosion. This erosion can have serious consequences for various structures on your property, such as seawalls, pool decks, sheds, and even your home’s foundation.

Seawalls, designed to protect coastal properties from the erosive force of waves, can be particularly vulnerable to the undermining effects of iguana burrows. The tunnels created by these reptiles can compromise the stability of the seawall, increasing the likelihood of collapse or damage during storms or high tides. Similarly, pool decks and sheds built on unstable ground due to iguana burrows may experience sinking or shifting, potentially rendering them unsafe or unusable.

The most critical concern, however, lies in the potential damage to your home’s foundation. Iguana burrows can weaken the soil beneath the foundation, leading to uneven settling and shifting of the structure. Over time, this can cause cracks in the walls, floors, and even the foundation itself. If left unaddressed, these issues can result in significant structural damage and costly repairs.

Personal experience has shown me the impact of iguana burrows on properties. A friend of mine had a beautiful seaside home with a well-maintained seawall. However, they noticed that the seawall began to develop cracks and become less stable over time. Upon investigation, it was discovered that iguanas had created an extensive network of tunnels beneath the seawall, eroding the soil and compromising its integrity. The damage was so severe that it required extensive repairs and reinforcement of the seawall.

To prevent or minimize the potential damage caused by iguanas, it is crucial to take proactive measures. Firstly, it is important to discourage iguanas from nesting on your property by removing any attractive features such as vegetation, food sources, or suitable nesting sites. Additionally, installing barriers or deterrents, such as fences or mesh, can help prevent iguanas from accessing your property and creating burrows.

Regular inspections of your property’s infrastructure, including seawalls, pool decks, and sheds, can help identify any signs of damage or erosion caused by iguana burrows. Prompt action should be taken to address any issues, such as repairs or soil stabilization, to prevent further damage and ensure the safety of your home.

Iguanas can indeed pose a threat to your home’s structural integrity through their digging and tunneling activities. The formation of extensive burrows can accelerate erosion, potentially damaging seawalls, pool decks, sheds, and even the foundation of your home. Taking proactive measures to discourage iguanas from nesting on your property and promptly addressing any signs of damage can help mitigate these risks and protect your home.
