Top Signs of Iguana Infestation on Your Property

A freshly dug hole beside a pool deck or seawall can look minor at first. Then a patio paver begins to shift, a prized hibiscus loses its leaves overnight, or droppings appear in the same place each morning. These are often among the top signs of iguana infestation on South Florida properties, especially where warm surfaces, dense landscaping, water access, and soft soil give green iguanas what they need to stay.

One iguana passing through does not always mean an infestation. Repeated feeding, basking, burrowing, nesting, or overnight sheltering on the property is different. When the same conditions keep drawing iguanas back, the issue can grow quickly and affect landscaping, structures, sanitation, and outdoor safety.

Top Signs of Iguana Infestation to Watch For

Burrows near foundations, seawalls, and patios

Burrowing is one of the clearest signs that iguanas are becoming established rather than simply visiting. Green iguanas dig tunnels to nest and shelter, often choosing dry, sunny ground near retaining walls, canal edges, seawalls, pool decks, walkways, foundations, and landscape borders.

A burrow opening may look like a shallow hole at first, but the tunnel beneath it can extend farther than expected. Loose soil, fresh digging, disturbed mulch, or a gradually widening entrance are common clues. On waterfront properties, burrows near a seawall deserve prompt attention because erosion and soil loss can compromise the area around the structure over time.

Not every ground hole belongs to an iguana. South Florida properties can also have activity from rodents, crabs, or other wildlife. The difference is usually the size of the opening, repeated soil displacement, nearby droppings, and visible iguana traffic. A professional assessment can identify whether a hole is active before it is closed.

Large droppings in recurring areas

Iguana droppings are hard to ignore once you know what you are seeing. They are usually dark, cylindrical, and often include a white or chalky urate portion. Fresh droppings may appear on pool decks, dock areas, patios, roofs, walkways, outdoor furniture, and beneath favorite basking spots.

The pattern matters as much as the droppings themselves. A single dropping may come from one passing animal. Several deposits in the same location over days or weeks suggest an established travel route, feeding area, or roosting site. This creates more than an appearance problem. Droppings can make hard surfaces slippery, contaminate outdoor gathering areas, and add cleanup demands for staff, residents, and property managers.

Use gloves for cleanup, keep pets and children away from the area, and disinfect the surface afterward. Cleaning alone, however, does not remove the reason iguanas are returning.

Chewed plants and stripped landscaping

South Florida landscaping can be an open buffet for green iguanas. They commonly feed on tender leaves, flowers, fruit, and new growth. Hibiscus, orchids, bougainvillea, roses, leafy vegetables, flowering annuals, and many ornamental plants can be especially vulnerable.

The damage often has a recognizable look: leaves disappear from lower branches, blossoms are eaten cleanly, and a healthy plant suddenly appears bare or unevenly stripped. In vegetable gardens, seedlings may be knocked down or eaten before they have time to establish. You may also see shallow tracks through mulch, flattened planting beds, or small piles of disturbed soil around irrigation lines.

Plant damage alone does not prove an infestation, because insects and other wildlife can create similar problems. But chewed vegetation combined with droppings, burrows, or regular sightings is a strong signal that iguanas are using the landscape as a food source.

Daily basking and predictable travel routes

Iguanas are creatures of habit when a property provides food, shelter, and warm places to rest. You may see them in the same sunny spot every morning, often on a roof, dock, pool coping, fence, seawall, retaining wall, or paved patio. As temperatures rise, they may move through the same tree line, hedge, or fence opening to reach a feeding area.

Watch for activity at similar times of day. A large adult resting near a pool does not necessarily mean there are many iguanas nearby, but repeated sightings of adults and smaller juveniles can indicate a breeding population. Multiple iguanas using the same route is an even stronger reason to address access points and nesting conditions.

Roof activity should not be overlooked. Iguanas can climb trees, fences, downspouts, and textured exterior surfaces. Droppings on a roof, in gutters, or below a favored tree limb may point to an elevated resting or entry area that needs inspection.

Nesting activity during breeding season

Female iguanas may dig nesting burrows in sunny soil, commonly in spring and early summer, though South Florida's climate can support activity beyond a narrow seasonal window. A female may make test holes before settling on a nesting site, so several disturbed areas can appear before one becomes a finished burrow.

Egg-related activity is a key reason not to simply fill holes with loose soil. If a burrow is active, improper closure may not solve the problem and can lead to new digging nearby. A site-specific plan should account for active animals, nesting locations, and safe burrow closure after the appropriate removal work is complete.

Damage around pools, structures, and outdoor equipment

Iguanas do not need to chew a building to cause expensive property concerns. Their burrows can undermine soil around hardscape features. Their weight and movement can damage fragile landscape edging, screens, and ornamental plants. Their droppings can stain surfaces and foul pool-adjacent areas, while persistent activity can make residents or guests reluctant to use outdoor spaces.

For HOAs, hotels, managed communities, and commercial properties, recurring iguana activity also creates a presentation and liability concern. A visibly damaged entry landscape or droppings near a walkway can affect the experience of residents, visitors, and customers. The sooner the property pattern is identified, the easier it is to target the conditions supporting it.

When a Sighting Becomes a Property-Wide Problem

The biggest warning sign is escalation. You might start with one adult iguana on a seawall, then notice juveniles in the hedge, droppings near the pool, and holes along the foundation. That progression suggests the property has become part of an active habitat network, rather than a place an iguana happened to cross.

Waterfront homes, canal-side communities, and properties with mature trees often need a broader inspection because iguanas can move easily between neighboring yards. A removal plan that focuses only on the animal currently visible may leave burrows, eggs, tree access, fence gaps, and attractive feeding areas untouched. That is why effective control combines humane removal with exclusion, burrow assessment, cleanup, and practical prevention.

What to Do When You Find Iguana Activity

Avoid trying to handle an iguana yourself. Large adults can bite, scratch, whip with their tail, or flee into a difficult-to-reach area. Do not block a burrow while you are unsure whether it is active, and do not use poisons or improvised traps that could harm pets, native wildlife, or people.

Instead, document what you see. Take photos of droppings, holes, plant damage, and the locations where iguanas appear. Note the time of day and whether activity is near a roof, pool, seawall, garden, or building entry point. This information helps a trained removal specialist map travel routes and identify the most effective trap placement or exclusion strategy.

For a persistent problem, a professional service should explain the next steps clearly: inspect the site, remove active iguanas humanely, assess burrows and nesting areas, seal practical entry points, protect vulnerable landscaping, and monitor for repeat activity. Iguana Jones Removal Services approaches South Florida properties this way because durable results come from addressing the habitat conditions, not just removing the most visible animal.

Prevention Depends on the Property

There is no single prevention fix for every property. A waterfront home may need attention around seawalls, docks, and canal-side vegetation. A pool property may need roof and fence access reviewed. A managed community may benefit from recurring monitoring across common areas, landscape beds, and drainage edges.

Reducing easy food sources can help. Keep fallen fruit picked up, protect vegetable gardens where practical, and avoid leaving pet food outdoors. Trim branches that give iguanas direct access to roofs or upper-level ledges, while keeping landscaping healthy and attractive. The goal is not to make a property barren. It is to remove the easy shelter, food, and access that make repeat activity more likely.

A few fresh droppings or a new burrow may seem manageable, but early action protects far more than a flower bed. It helps keep your outdoor space safe, clean, stable, and ready to enjoy.
