Wildlife officials are raising concerns about the spread of an invasive lizard species—Argentine black and white tegus—now being spotted in Georgia, Florida, and even South Carolina. Originally brought to the U.S. through the pet trade, these large lizards are becoming a serious ecological threat.
What is a Tegu?
The Argentine tegu is a black and white lizard native to South America. It can grow up to 4 feet long and weigh over 10 pounds. They’re ground dwellers, strong swimmers, and known to brumate (a form of hibernation) during colder months. Tegus typically breed in the spring, laying around 35 eggs per year, and can live up to 20 years.
What Do They Look Like?
Tegus have a distinctive black-and-white banded pattern across their backs and tails. Young tegus are similarly marked but have bright green heads, which fade after about a month.
Where Have They Been Spotted?
In Georgia, tegus have been reported in counties like Tattnall, Toombs, Gwinnett, DeKalb, and even as far north as Union County near North Carolina. Florida has established reproducing populations in Hillsborough, Miami-Dade, Charlotte, and now St. Lucie counties.
Are They Dangerous?
While not naturally aggressive to humans, tegus will defend themselves with tail whips, sharp claws, and powerful jaws. Their real threat is ecological—they feed on the eggs of protected species like alligators, gopher tortoises, quail, and turkeys. They also consume fruits, veggies, pet food, chicken eggs, and even small animals.
Can You Kill a Tegu?
Yes, in both Florida and Georgia, tegus can be humanely killed on private property with the landowner’s permission. Florida allows year-round removal on 32 commission-managed lands without a permit. In Georgia, they can be killed during legal hunting seasons on public Wildlife Management Areas, though trapping isn’t allowed.
