The Argentine tegu Georgia wildlife crisis is escalating…a giant South American reptile is spreading across 30 counties in Georgia, threatening native wildlife and alarming authorities.
Imagine stepping into your backyard and coming face-to-face with a four-foot-long lizard that has no business being in Georgia. That’s exactly what residents across the southeastern United States are now experiencing, and wildlife officials aren’t asking people to simply back away. They’re asking them to kill on sight.
Meet the Argentine Black and White Tegu
The Argentine black and white tegu (Salvator merianae) is not your average backyard lizard. Native to South America, specifically Argentina, Brazil, Paraguay, and Uruguay, this reptile is the largest of all tegu species, capable of growing up to 4 feet long and weighing over 10 pounds. With its striking black-and-white patterned scales, muscular body, and surprisingly fast movement, the tegu is built to survive and, unfortunately, to thrive far beyond its natural range.
Despite their intimidating size, tegus are actually considered relatively docile toward humans. This docile temperament is precisely what made them popular in the exotic pet trade. And that popularity is exactly how they ended up in Georgia.
How Did They Get Here?
The story is a familiar one in the world of invasive species: humans brought them in, then let them go.
Over the years, tegus became trendy exotic pets across the United States. But as they grew larger and more demanding, many owners released them into the wild or allowed them to escape. Warm southern climates, particularly in Florida and Georgia, closely mirror the tegus’ native South American habitat, giving them everything they need to not just survive but establish full breeding populations.
The result? A growing reptilian invasion that has been slowly spreading since at least 2018, when the Georgia Department of Natural Resources (DNR) first documented a wild population in Toombs and Tattnall counties in southeast Georgia.
The Situation in 2026: 30 Counties and Counting
What started as a localized problem has grown into a statewide concern. As of June 2026, the Georgia DNR has confirmed tegu sightings in 30 counties across the state, with the core population stretching from Lyons to Reidsville in the southeast.
Since tracking began in 2018, more than 30 tegus have been captured or killed in Tattnall and Toombs counties alone. But biologists warn that the true number of animals in the wild is likely far higher and that the window to control the population before it becomes unmanageable is narrowing fast.
Daniel Sollenberger, a senior wildlife biologist with Georgia DNR’s Wildlife Resources Division, has been candid about the challenge: these animals are fast, elusive, and difficult to trap.
Why Tegus Are Such a Big Problem
The tegu’s greatest strength as a survivor is also its greatest threat to local ecosystems: it will eat almost anything.
Georgia wildlife officials have identified several critical concerns:
Eggs of ground-nesting birds: Tegus destroy the nests of species like bobwhite quail, wild turkeys, and whip-poor-wills.
The endangered gopher tortoise tegus raid tortoise burrows and consume their eggs, threatening an already vulnerable protected species.
Pet food and poultry tegus have been known to eat chicken and turkey eggs, and will raid pet food left outside
Disease transmission officials warn that tegus may spread diseases to native wildlife and potentially to humans.
Food web disruption as generalist predators with no natural enemies in Georgia, tegus can rapidly destabilize local ecosystems
And they reproduce fast. A single female can lay more than 30 eggs per year, and tegus can live for up to 20 years. Do the math, and the urgency becomes clear.
What Officials Are Telling Residents
The Georgia DNR has issued an unusually direct message to the public: if you see one, report it — and if you can, kill it.
Specifically:
- Tegus can be humanely euthanized on private property with the landowner’s permission, in accordance with local laws
- Releasing non-native animals into the wild is illegal in Georgia, even if keeping tegus as pets remains legal
- Residents who spot a tegu — alive or dead — should report the sighting immediately to the DNR to help track the spread
The University of Georgia Cooperative Extension and Georgia Southern University are actively assisting DNR in trapping and removal efforts. The U.S. Geological Survey is also involved in assessing the population’s range and behavior.
A Growing Problem Across the Southeast
Georgia is not alone. The Argentine tegu has established breeding populations in Florida, where the problem is even more advanced, and sightings have been reported in South Carolina as well. The species is steadily expanding its footprint across the warm, humid Southeast, and experts fear that without aggressive intervention, control may become impossible.
Florida has been battling tegu populations for over a decade with only partial success, serving as a cautionary tale for what Georgia could face if action isn’t taken swiftly.
What You Can Do
Whether you’re a Georgia resident or simply someone who cares about wildlife, here’s how you can help:
- Report sightings Use the Georgia DNR’s online portal at georgiawildlife.com/tegus or contact your local UGA Extension office
- Don’t release exotic pets ever. If you can no longer care for an exotic animal, contact a rescue organization or your local wildlife authority
- Spread awareness The more people know what a tegu looks like and why it’s dangerous, the faster sightings get reported
The Bigger Picture
The Argentine tegu story is a stark reminder of how quickly the exotic pet trade can destabilize natural ecosystems. A lizard that belongs in the grasslands of South America is now roaming the forests and farmlands of Georgia not because of climate change or natural migration, but because of human choices.
The species itself is not the villain here. The tegu is simply doing what tegus do: eating, surviving, and reproducing. The responsibility lies with the systems, regulatory and cultural, that allow exotic animals to enter homes without adequate safeguards against their eventual release into the wild.
For now, Georgia faces a race against time. And in that race, a four-foot lizard is moving faster than most people expected.
