Georgia Battles Invasive 4-Foot Lizard Threat
21 Jun
Summary
- Argentine black and white tegus are invasive in Georgia.
- Lizards threaten native wildlife by eating eggs and young.
- DNR is trapping and euthanizing invasive tegus.

Wildlife officials in Georgia are raising alarms about the Argentine black and white tegu, an invasive species now established in the state. These South American lizards, capable of reaching four feet in length, are a significant concern due to their impact on native ecosystems.
Native to Brazil, Paraguay, Uruguay, and Argentina, the tegu is a voracious eater. Their diet includes the eggs of ground-nesting birds like quail and turkeys, as well as young of native reptiles. This predatory behavior poses a direct threat to Georgia's wildlife populations.
The Georgia Department of Natural Resources (DNR) is actively managing the invasive tegu population. Efforts include trapping these lizards, humanely euthanizing them, and documenting their dietary and reproductive status. The DNR also encourages public reporting of sightings to aid in control efforts.
Concerns extend beyond predation; tegus can potentially spread Salmonella bacteria, which is harmful to humans, particularly children and the elderly. While not typically aggressive towards people, their size and physical attributes warrant caution. The DNR advises respecting but not fearing these reptiles.
