Live cage traps baited with ripe fruit are the most effective and widely used method for catching green iguanas on residential property. In South Florida, where iguana populations can reach over 600 individuals per hectare, trapping is a practical option for homeowners dealing with landscape destruction, burrow damage, and nuisance behavior. Here’s what works, what the rules are, and how to do it safely.
Why Iguanas Are Worth Trapping
Green iguanas are an invasive species in Florida, and the damage they cause goes well beyond eating garden plants. Their burrowing destabilizes infrastructure: canal banks in South Florida have been found with up to 2,800 burrows per hectare, and repairing a single burrow in a canal wall costs roughly $400. In 2020, iguana damage to a dam in Palm Beach County required $1.8 million in repairs.
The ecological toll is significant too. Iguanas feed on plants across 110 genera and 51 plant families. Their range in Florida overlaps with established critical habitat for 21 federally listed species and threatens 54 imperiled flowering plant and butterfly species. They’re not a nuisance you need to feel guilty about removing.
Live Cage Traps: The Standard Approach
A standard wire cage trap (the same style used for raccoons or opossums, sized appropriately) is the go-to for most homeowners. The University of Florida Extension recommends baiting with grapes, ripe melon, papaya, or mango. Iguanas are herbivores with a strong preference for sweet, fragrant fruit, so the riper the better.
The key detail most people miss is prebaiting. Set the trap out with bait but don’t arm the trigger mechanism for several days. Let the iguanas walk in and out freely, getting comfortable with the trap as a food source. Once they’re regularly visiting, set the trap to close. This dramatically improves your catch rate compared to setting a trap cold.
Two modifications make cage traps much more effective for iguanas specifically:
- Cover the wire floor. Spread leaf litter, mulch, or soil over the bottom of the trap so the iguana can’t feel wire mesh under its feet. Bare wire feels unnatural and makes them hesitant to walk in.
- Use a drift fence. Place a board or piece of plywood alongside the trap to act as a guide wall. Iguanas tend to follow edges and barriers, so a simple board funneling them toward the trap entrance increases the chances they’ll walk right in.
Where and When to Set Traps
Placement matters more than trap quality. Position traps along the routes iguanas already use: seawalls, fence lines, canal edges, the base of trees where they bask, and near burrow entrances. Iguanas are creatures of habit and follow the same paths daily.
Iguanas are strictly diurnal, meaning they’re only active during daylight hours. Set and monitor traps during the day. This timing has a practical bonus: nocturnal animals like raccoons, opossums, and feral cats are far less likely to wander into a daytime-only trap, reducing unwanted catches. Check traps frequently throughout the day, as a trapped iguana left in direct Florida sun can overheat quickly.
Snares as an Alternative
Pole snares and fixed snares are another option, particularly around burrow entrances and gaps under fences. For fixed snares, the bottom of the loop should sit 2 to 3 inches above the ground, adjusted based on the size of the iguanas you’re targeting. Place them at burrow openings, holes under fencing, along seawalls, or anywhere iguanas regularly pass through.
Like cage traps, snares should only be deployed during daylight hours and checked frequently. A snare left out overnight will catch raccoons and other non-target animals. Snares require more skill and attentiveness than cage traps, so if you’re new to iguana removal, start with a cage trap.
Florida’s Legal Rules for Iguana Trapping
Green iguanas are not protected in Florida except by anti-cruelty laws. You can capture and humanely kill them on private property with the landowner’s permission, no permit or hunting license required. The same applies on 32 state-managed public lands in South Florida under a standing executive order.
There are two rules that trip people up:
- No relocation. You cannot trap an iguana and release it somewhere else in Florida. Captured iguanas must be humanely dispatched or kept. Driving them to a park or empty lot and letting them go is illegal.
- Live possession requires a permit. If you want to keep a live captured iguana (even temporarily for control purposes), you need a permit from the Florida Fish and Wildlife Conservation Commission.
Humanely Dispatching a Trapped Iguana
Florida law requires that any killing method be humane, and the American Veterinary Medical Association recommends a two-step process for reptiles. The first step renders the animal immediately unconscious. The second step, called pithing, involves inserting a rigid metal tool into the brain cavity with multi-directional movement to ensure the brain is fully destroyed and the animal cannot regain consciousness.
Acceptable tools for the first step include captive bolt devices and firearms or pre-charged pneumatic air guns. For most homeowners who aren’t comfortable with this process, hiring a professional nuisance wildlife trapper is the practical choice. Professional removal services in South Florida typically cost around $500 for a three-week effort, $400 per month for weekly visits, or $1,900 for an annual on-call contract.
Safety and Handling Precautions
Even a trapped iguana can injure you. Large adults can deliver a painful bite with their serrated teeth, and their tails are muscular enough to leave welts or break skin with a whip. Wear thick gloves and long sleeves when handling a cage trap with an iguana inside, and approach from behind the animal when possible.
The less obvious risk is Salmonella. Iguanas, like all reptiles, commonly carry Salmonella bacteria on their skin, in their droppings, and on surfaces they contact. Wash your hands thoroughly with soap and water for at least 20 seconds after handling traps, cleaning equipment, or touching anything an iguana has been near. Children under 5, pregnant women, elderly adults, and anyone with a weakened immune system should not handle iguanas or iguana traps at all. Don’t eat, drink, or touch your face until you’ve washed up.
Clean traps and equipment outdoors rather than in your kitchen sink or bathtub. Use disposable gloves during cleanup to avoid spreading bacteria to household surfaces.
