Dog-sized invasive lizards are appearing more often in southeast Georgia, prompting wildlife officials to ask residents for help containing a population that threatens native birds and reptiles.
Argentine black and white tegus have been reported increasingly this year in Toombs and Tattnall counties, Outdoor Life reported. Georgia Department of Natural Resources biologist Daniel Sollenberger said the agency cannot estimate how many are in the wild because the animals are difficult to locate and count.
The South American reptiles can grow up to 4 feet long and weigh 10 pounds or more. The Georgia Department of Natural Resources says they eat eggs from ground-nesting birds, including quail and turkeys, along with alligator eggs and young gopher tortoises. Officials are concerned tegus could spread parasites, carry salmonella and contaminate crops.
Georgia’s only known wild population is concentrated in eastern Toombs and western Tattnall counties. The state began investigating reports there in 2018 and believes the population most likely began with exotic pets that escaped or were intentionally released. Tegus can survive cold months through brumation, and females can lay about 35 eggs annually.
Residents who spot a tegu should note the location, take a photo if possible and submit it through the Georgia Invasive Species Task Force. DNR says the animals may be humanely trapped or killed year-round on private property with the landowner’s permission, subject to local ordinances and safety precautions. Different rules apply on state wildlife management areas.
Tegus are not considered aggressive toward people, but they can defend themselves with sharp teeth, claws, strong jaws and whipping tails. Officials warn residents to avoid confusing smaller tegus with protected juvenile alligators and to report every sighting, alive or dead.
Early reports could help Georgia contain the population before it spreads farther.
