Iguana Removal in South Florida: Managing South Florida's Iguana Epidemic
Green iguanas have overrun pool areas, seawalls, and neighborhoods from Coral Gables to Key Biscayne. Miami-Dade County Pest Control covers legal removal, exclusion, and damage prevention in Miami-Dade.
Miami-Dade's Iguana Problem: How We Got Here
Green iguanas (*Iguana iguana*) arrived in Miami-Dade County through the exotic pet trade in the 1960s and 70s. Released or escaped pets found South Florida's Zone 10 tropical climate perfectly suited to their needs — warm year-round temperatures, abundant vegetation, and virtually no natural predators. What began as isolated feral populations has grown into one of the most significant urban wildlife management challenges in the United States.
Today, green iguanas are present throughout Miami-Dade County in numbers that wildlife managers describe as epidemic. From the waterfront estates of Coral Gables and Coconut Grove to the bay-front properties of Key Biscayne, from the canals of Hialeah to the residential neighborhoods of Kendall and Homestead, iguanas are everywhere — and their populations continue to grow. The Florida Fish and Wildlife Conservation Commission (FWC) classifies green iguanas as an invasive species with no protected status, encouraging their humane removal by property owners and licensed professionals.
The Damage Iguanas Cause in Miami-Dade
Seawall and Foundation Damage
The single most costly type of iguana damage in Miami-Dade County involves their extensive burrowing behavior. Female iguanas excavate burrows for nesting, and these burrows can extend six feet or more into the ground. When iguanas burrow into seawall embankments — extremely common along South Florida's extensive canal system and bay-front properties — the structural integrity of the seawall is compromised. Water infiltrates the burrow channels, accelerating corrosion of the seawall's steel reinforcement and destabilizing the fill material behind the wall. Seawall repair or replacement in Miami-Dade County can cost $500 to $1,500 per linear foot. The damage from iguana burrows is a genuine financial catastrophe for waterfront homeowners who don't address the problem proactively.
Iguana burrows near foundations, sidewalks, pool decks, and driveway edges cause similar structural concerns, though typically less severe than seawall damage.
Landscape Destruction
Iguanas are voracious herbivores that consume a wide range of ornamental plants common in South Florida landscaping: hibiscus, bougainvillea, orchids, impatiens, roses, and many flowering shrubs are among their favorites. They also consume fruits including mangoes, bananas, and figs from residential trees. A property in Coral Gables or Key Biscayne with extensive tropical landscaping can sustain thousands of dollars in plant damage each growing season from an established iguana population.
Pool and Outdoor Living Area Contamination
Iguanas frequently use pool decks, dock areas, and outdoor furniture as basking platforms. Their droppings pose a health concern — iguanas commonly carry *Salmonella* bacteria, and their feces deposited in pool water or on pool surrounds represent a genuine contamination risk. This is particularly relevant for properties with children who use pools regularly.
Infrastructure and Electrical Hazards
Iguanas have caused power outages throughout Miami-Dade County by entering electrical transformers and substations. They also damage irrigation systems by biting through PVC pipes and nesting inside equipment housings.
Legal Framework for Iguana Removal in Miami-Dade
Under current FWC regulations, green iguanas are not protected in Florida. Property owners in Miami-Dade County may remove iguanas from their own property without a permit. However, Florida's animal cruelty statutes still apply — removal methods must be humane. Permitted methods include:
- Live trapping followed by humane euthanasia
- Pellet or air gun (where local ordinances permit firearm discharge)
- Catch poles and manual capture
- Professional removal services
Critical legal point: It is a violation of Florida law to capture iguanas and release them elsewhere. Captured iguanas must either be kept or humanely euthanized. This requirement is strictly enforced in Miami-Dade County and throughout the state.
South Florida municipalities including Coral Gables and Key Biscayne have their own ordinances regarding wildlife removal, and some residential associations have additional requirements. Always confirm local regulations before beginning removal activities.
Professional Iguana Removal and Exclusion in Miami-Dade
While property owners can legally remove iguanas themselves, professional removal by experienced wildlife control operators is more effective for established populations. Miami-Dade County Pest Control coordinates professional iguana removal throughout Miami-Dade County — call (786) 353-0097 to schedule an assessment.
Professional programs typically include:
Population reduction: Systematic trapping and removal of iguanas from the property using live traps baited with attractive vegetation. Multiple rounds of trapping are typically needed to significantly reduce an established population.
Exclusion and habitat modification:
- Installing slick metal banding around tree trunks to prevent climbing access to the canopy
- Applying smooth metal or PVC barriers on seawall caps to prevent iguanas from accessing the top of walls
- Installing wire mesh around garden beds and under deck edges
- Filling active burrows with concrete, compacted gravel, or expanding foam after confirming no iguanas are inside
Landscaping modifications: Replacing iguana-attractive plants with species they find less appealing and removing ground-level fruit sources.
Ongoing monitoring: Regular inspections and trapping to address recruitment from neighboring properties — a critical component in Miami-Dade County where iguana populations in adjacent properties will continuously replenish a cleared area.
Frequently Asked Questions
Do iguanas bite?
Yes. Adult iguanas have sharp teeth and powerful jaws capable of inflicting a serious wound. They also have sharp claws and a powerful tail whip they use defensively. Never attempt to handle an iguana without professional training and proper equipment.
Why are there so many more iguanas now than ten years ago?
Iguana populations in Miami-Dade County suffered a major setback during the January 2018 cold snap when temperatures dropped enough to cold-stun large numbers of iguanas. However, populations recovered rapidly. A cold event in January 2020 again reduced numbers, but the population has rebounded. The underlying conditions — tropical climate, abundant food, no natural predators — ensure continued population growth between cold events.
Are iguanas found throughout all of Miami-Dade?
Yes, but they are most concentrated in areas with abundant water and vegetation: along canals, near Biscayne Bay, in Coral Gables, Coconut Grove, Key Biscayne, Pinecrest, and waterfront areas of Miami Beach and North Bay Village. They are also common in Hialeah, Kendall, and throughout suburban Miami-Dade County.
