Iguanas Invasive Species in Florida: Current Status and Spread
Green iguanas are established as an invasive species in Florida, with populations concentrated in South Florida and expanding northward due to warm winters and urban landscaping. The Florida Fish and Wildlife Conservation Commission lists iguanas as a regulated nonnative species, and the U.S. Fish and Wildlife Service tracks them as an introduced reptile with growing range overlap in Miami-Dade, Broward, Palm Beach, and neighboring counties U.S. Fish and Wildlife Service.
Florida's subtropical climate, canal systems, and ornamental trees provide food and shelter, allowing iguanas to thrive in residential and commercial landscapes. The Florida Fish and Wildlife Conservation Commission receives thousands of nuisance complaints annually, and local wildlife control operators report rising demand for iguana removal services in both urban and suburban areas Florida Fish and Wildlife Conservation Commission.
Ecological and Property Damage Caused by Iguanas
Iguanas damage seawalls, sidewalks, and canal banks by burrowing, which can weaken infrastructure and increase maintenance costs for homeowners and local governments. They also feed on ornamental plants, fruit trees, and garden vegetation, creating conflicts with residents and landscaping businesses across South Florida Forbes.
Ecologically, iguanas compete with native wildlife for food and habitat, disturb nesting sites for ground-nesting birds and reptiles, and contribute to erosion through extensive burrowing. Their feces can affect water quality in canals and ponds, adding to the ecological pressure already faced by native Florida species National Park Service.
Removal, Control, and Regulation of Iguanas in Florida
Florida law allows property owners to kill iguanas on their own land year-round, and the state encourages removal through public education and targeted trapping programs. Professional wildlife trappers and pest control companies offer removal services, with costs varying based on property size, infestation level, and access to burrows U.S. Fish and Wildlife Service.
Local governments and utilities fund habitat management and burrow stabilization projects to reduce damage to critical infrastructure such as levees and seawalls. Public agencies continue to monitor iguana populations and track range expansion using sighting reports, roadkill data, and field surveys to guide control priorities Florida Fish and Wildlife Conservation Commission.
