Green iguanas use warm coastal and developed habitats, often near water. A sighting, hole or county map does not by itself prove an established population.
Where green iguanas live in Florida
Green iguanas use warm parts of Florida where food, shelter and basking areas occur together. They occupy developed neighborhoods as well as some natural habitats, often close to permanent water. “Iguana” covers multiple introduced species; this guide describes green iguanas, Iguana iguana.
FWC describes established populations along portions of Florida’s Atlantic and Gulf coasts, including the Keys. A sighting outside those areas does not by itself prove a breeding population. Distribution records change and are not a property-specific guarantee that an iguana is present or absent.
Native habitat and the route into Florida
Green iguanas are native to tropical parts of the Americas and some Caribbean islands. UF/IFAS describes tropical rain forest, dry forest and savanna habitats, often near water. The animals did not originate in Florida.
Pet escapes and intentional releases contributed to their introduction and spread. That history does not establish where a particular animal came from, nor does it justify releasing unwanted pets. The companion collection of iguana facts and behavioral patterns is useful for recognizing the broader animal, while this article focuses on the places it uses.
Coastal records are different from an exact boundary
FWC lists green-iguana populations in several southeastern coastal counties and in Collier and Lee counties on the Gulf side. It also notes reports farther north that may involve escaped or released captive animals. UF/IFAS describes a predominantly coastal pattern across much of central and southern Florida and identifies cold as a limiting factor.
Those summaries have different wording and purposes. Neither supports drawing an unchanging line across the state or claiming that every place south of a line supports an established population. For regional context, consult Florida iguana distribution and the underlying agency information. County-level occurrence is not an abundance estimate, and a map of reports is not a live census.
Trees, shrubs and sunny built surfaces
Green iguanas are excellent climbers and often use trees. UF/IFAS describes daytime basking on the ground and in trees or shrubs, as well as on docks, seawalls, sidewalks and other surfaces in human-modified areas. A property can offer these resources even without a dense canopy.
At night, animals may use trees, rock crevices or underground shelter. For the sleep-specific question, see where iguanas sleep and roost at night. A basking spot is not necessarily a nest, and an animal returning to a surface does not prove that it lives permanently on that property.
Waterways and banks offer connected habitat
Green iguanas are strong swimmers and are commonly associated with permanent water. FWC describes canals as dispersal corridors; UF/IFAS describes canals and levees as places that can support range expansion. Trees, nearby vegetation and shelter may make a waterfront setting useful in several ways.
This does not establish a fixed travel distance or imply that every canal contains iguanas. Keep a safe distance from shorelines and animals. Damaged banks or possible undermining need a qualified assessment rather than a homeowner attempt to locate wildlife underground. Green-iguana adaptations explains the climbing and swimming traits behind habitat use without treating them as proof of an uncontrollable population.
Burrows and human-made shelter require caution
FWC lists burrows, culverts, drainage pipes and rock or debris piles as refuges in cleared habitats. UF/IFAS distinguishes nest burrows from other places animals use for shelter. A hole alone cannot identify its occupant or confirm a green-iguana nest.
Other wildlife may use burrows, including protected species. Photograph visible activity from a distance and record where it occurs. Do not seal, excavate or flood a potentially occupied hole. If there is a concern about a foundation, seawall or sidewalk, address the structural hazard with an appropriately qualified professional as well as assessing the wildlife issue.
Why food and temperature affect property use
Flowering ornamentals, shoots, leaves and fruit can attract feeding green iguanas. FWC and UF/IFAS document plant damage, but damage patterns overlap with other animals and causes. See feeding-related yard damage for a plant-focused assessment. Do not feed wildlife or assume a product will eliminate activity without evidence.
Temperature matters because green iguanas depend on external heat. Cold can affect movement and survival, but there is no universal temperature that predicts every animal’s response. A motionless animal should not be handled or brought indoors. Habitats and local exposure vary, so a cold spell is not a dependable management plan.
Assess repeated sightings without approaching animals
Note the date, general weather, location, plant use and visible entry or shelter points. If possible, photograph identifying features from a safe distance rather than moving closer. Color is not sufficient for identification; the guide to iguana identification explains useful features. The discussion of how friendly wild iguanas really are should not be read as an invitation to interact with a wild reptile.
Keep children and pets clear. CDC warns that reptiles and contaminated environments can carry Salmonella, even if an animal looks healthy. Avoid contact with droppings and seek professional guidance for contamination concerns.
For recurring damage, discuss iguana-removal assessment with On Demand Pest Control and confirm service scope directly. Current FWC guidance says captured green iguanas cannot be relocated and released elsewhere in Florida; a permit is required for live possession of captured green iguanas for eradication and control. Property permission and anti-cruelty requirements still apply. No handling or relocation technique is recommended here.
Frequently Asked Questions
-
Where do iguanas live in Florida specifically?
FWC describes populations along southeastern Atlantic counties, the Keys and parts of the southwestern Gulf coast, including Collier and Lee. Reports elsewhere do not necessarily show established breeding populations. Consult current agency information instead of treating a state-spanning line as an exact boundary.
-
Where are iguanas from originally?
Green iguanas originate in tropical parts of the Americas and some Caribbean islands. Pet escapes and intentional releases contributed to their Florida introduction; an individual sighting does not reveal its introduction history.
-
Why do iguanas live near water in Florida?
They are strong swimmers and often occur near permanent water, with vegetation and shelter nearby. Canals may act as movement corridors. Water alone does not prove iguanas are present or establish a population count.
-
Can iguanas survive cold weather in Florida?
Cold can impair movement or cause death and limits their distribution. Exposure, shelter and conditions affect the outcome; a motionless animal is not necessarily dead. Do not handle it or bring it indoors.
-
Do iguanas live in burrows or in trees?
Both can be used. UF/IFAS describes trees, rock crevices, burrows and human-made refuges. A hole alone cannot identify the animal using it, and nesting should not be inferred from an ordinary shelter or basking site.
-
What makes a property attractive to iguanas?
Plant food, sunny basking surfaces and available shelter can make a site useful, often near water. Record repeated sightings and actual damage before attributing a problem to iguanas. Seek professional assessment rather than feeding animals or sealing unidentified burrows.
