Iguanas Invade Florida: What Homeowners Need to Know Now!

Lighthouse Point, Florida, USA - As summer warmth envelops Florida, a different kind of chill is making its presence known—particularly among the green iguana populations that have become a point of discussion for many homeowners. These large lizards, while charismatic, are increasingly regarded as a nuisance, impacting both local landscapes and ecosystems.

Green iguanas have become a common sight across Florida since they were first reported in the 1960s. Classified as an invasive species, they pose notable challenges to both the environment and residents. The Naples Daily News reports that their presence can lead to significant landscape damage, as iguanas are notorious for munching on ornamental plants and causing erosion with their burrowing habits.

Legal Concerns and Homeowner Responsibilities

Residents are often left wondering what they can do about these lizards that wreak havoc on their gardens. It is legal to remove iguanas from private property in Florida, provided landowners take ethical measures. Additionally, on public lands, removing these reptiles can be done without needing a permit, indicating just how problematic they have become (UF IFAS Extension).

Green iguanas don’t just damage plants; they also pose health risks. These creatures can transmit Salmonella, a serious bacteria, through contact with contaminated surfaces, creating hygiene concerns for those who encounter them. Furthermore, their droppings can litter patios and docks, making them less than ideal roommates in our backyards.

A Deeper Look into the Iguana’s World

From a biological standpoint, green iguanas can span lengths of over six feet, with adult males frequently topping 17 pounds. Their distinctive look—often bright green, but can range into browns and blacks—is complemented by vibrant markings, especially during breeding season, when males flaunt orange and pink colors. Interestingly, their large, flap-like dewlaps not only serve as a mating signal but also help regulate their body temperature (FWC).

Their diet is largely herbivorous, consisting of leaves, flowers, and fruit, though they sometimes indulge in small animals or bird eggs. This broad diet makes them effective foragers, and their climbing abilities allow them to find food in varied environments. However, their thriving presence in both urban and natural areas raises concerns about their impact on indigenous species, such as tree snails and the endangered Miami Blue butterfly.

The Florida region is recognized as the epicenter for nonnative reptiles, a consequence of favorable climatic conditions and human activities, including the exotic pet trade. The green iguana is among over 150 documented nonnative reptile species in Florida, with its introduction largely stemming from intentional and unintentional releases that contributed to its burgeoning populations (UF IFAS Extension).

Conclusion and Call to Action

As Floridians navigate issues posed by these scaly invaders, awareness is key. Residents are encouraged to report any iguana sightings outside their known ranges and consider humane removal strategies on private properties. As we continue to foster a healthy balance between human life and the wildlife surrounding us, engaging in responsible actions regarding invasive species remains crucial.
