Wildlife officials in parts of the United States are urging residents to help control the spread of invasive Argentine black and white tegu lizards, warning that the species poses a growing threat to local ecosystems. Authorities in Georgia have specifically called on the public to report sightings and assist in efforts to prevent the reptiles from establishing larger populations across the region.

The Georgia Department of Natural Resources (DNR) has advised residents in the southeastern part of the state to remove tegus when encountered and notify wildlife officials. According to state biologists, members of the public who are unable to safely deal with the reptiles should document sightings with photographs and contact authorities, who can provide guidance or arrange trapping and removal efforts.

Native to South America, Argentine black and white tegus were introduced to the United States through the exotic pet trade. Over time, some escaped or were released into the wild, allowing populations to become established in states such as Florida, Georgia and South Carolina. The reptiles can grow up to four feet in length and are known for their adaptability to a wide range of environments.

Wildlife experts warn that the invasive lizards threaten native species by feeding on eggs, small mammals, reptiles and ground-nesting birds. In addition to their impact on wildlife, tegus can damage agricultural crops and private property. Officials have also noted concerns that the reptiles may carry exotic parasites and harmful bacteria, including Salmonella, posing potential risks to both animals and humans.

State agencies have expanded monitoring and control programmes in affected areas, with trapping and removal operations underway in several locations. Experts say early intervention is essential to preventing the species from spreading further, as unchecked populations could cause long-term ecological damage. The latest appeal forms part of broader efforts across the United States to manage invasive species before they become permanently established in vulnerable habitats.
