Georgia Argentine Tegu Invasive Population Reaches Critical Levels in Southern Georgia, Officials Warn.
(SAVANNAH, GEORGIA) – The Georgia Department of Natural Resources has issued an urgent advisory regarding the Argentine black and white tegu, an invasive reptile species whose population in southern Georgia has reached critical levels, threatening native wildlife and local ecosystems.
WHAT: A confirmed surge in the Argentine tegu population. These large, non-native lizards, known for their voracious appetite, consume the eggs of ground-nesting birds, such as quail and turkeys, as well as small mammals and reptiles. They are also known to raid chicken coops and damage crops.
WHO: The Georgia Department of Natural Resources, alongside the U.S. Geological Survey and local conservation groups, is leading monitoring and eradication efforts.
WHERE: The infestation is most concentrated in Toombs, Tattnall, and Montgomery counties, though sightings have been reported as far north as Macon. Officials stress the species thrives in the warm, humid climate of the Georgia Coastal Plain.
WHEN: The problem has escalated rapidly since initial sightings were confirmed in 2019. The population is expected to continue growing through the summer breeding season, posing a heightened risk to native species.
WHY: Escaped or released pet tegus—imported from South America—have established a breeding population. They have no natural predators in Georgia, allowing their numbers to explode unchecked. The species is classified as a “high-risk” invasive due to its adaptability and reproductive rate.
HOW: Residents are urged to report any tegu sightings immediately via the GA DNR’s invasive species hotline. Qualified trappers are deploying cage traps and conducting targeted removal. The public is strongly advised not to approach or attempt to capture the lizards, as they can deliver a powerful bite.
