The giant Argentine tegu invasion in Georgia is a complex issue that has been making headlines in recent years. The tegus, which are native to South America, have been found in the wild in Georgia since the 1940s, but their population has been growing rapidly since the 1990s.
These reptiles are highly adaptable and can thrive in a variety of environments. They are also skilled at escaping from captivity, which has contributed to their rapid population growth in the wild.
In Georgia, the tegus have been causing significant problems for farmers and gardeners, as they feed on crops and can also carry diseases that can be transmitted to other animals and even humans.
Safety and Regulations
You can kill a tegu on private property in Georgia with the landowner's permission and using legal methods in accordance with local ordinances, animal cruelty laws, and safety precautions.
Using traps to catch tegus is not allowed on public Wildlife Management Areas, but you can kill them with firearms legal for the current hunting season. Anyone who sees a tegu on a WMA should also alert that region's Game Management office.
Are Dangerous?

Tegus are not considered aggressive toward people, but they will defend themselves if threatened. They can react fast and lash with their tails.
Tegus have sharp teeth and claws, and strong jaws, which can be a concern if you're handling them. They are wild animals and should be treated with caution.
Tegus are a natural threat because they have few predators and can multiply quickly. This means their population can grow rapidly, leading to potential problems.
They eat the eggs of ground-nesting birds, including quail and turkeys, and other reptiles like the American alligator and gopher tortoise, which are protected species.
Is It Legal to Kill a Tegu?
If you're considering killing a tegu, it's essential to understand the laws surrounding it. Tegus can be trapped or killed on private property in Georgia with the landowner's permission.
To do so, you must use legal methods in accordance with local ordinances, animal cruelty laws, and safety precautions. This is crucial to avoid any potential issues.
On public Wildlife Management Areas, tegus can be killed with firearms legal for the current hunting season. However, using traps to catch tegus is strictly not allowed.
If you spot a tegu on a WMA, alert that region's Game Management office immediately.
Care and Housing
To keep your giant Argentine tegu happy and healthy, you'll need to provide a spacious and secure enclosure. Adult tegus require a minimum of a 6-foot by 3-foot by 2-foot enclosure, with double that size recommended for multiple tegus.
A log or box for hiding is essential, as tegus love to burrow and hide. Fill it with slightly damp sphagnum moss to aid with shedding and humidity.
Tegus are natural diggers, so you'll need a substrate that's absorbent and easy to clean. Cypress mulch, orchid bark, or eucalyptus mulch are great options, but avoid wood chips, ground corn cobs, or stone gravel due to ingestion risks.
How Many in Georgia
In Georgia, there are approximately 1.1 million people experiencing homelessness, which is about 3.8% of the state's population.
The number of homeless individuals in Georgia has been steadily increasing over the years, with a 12% rise in the last decade alone.
Georgia has a total of 4,600 emergency shelter beds available, but they are often filled to capacity, leaving many without a safe place to stay.

The state has a shortage of affordable housing units, with only 1 in 5 households able to afford the median home price of $240,000.
According to the Georgia Housing Finance Authority, there are over 100,000 households in the state who are severely cost-burdened, meaning they spend more than 50% of their income on rent or mortgage.
Housing BW
Housing your Argentine Black and White Tegu requires some careful planning.
Argentine black and white tegus are big, so they need large and secure enclosures. A minimum of a 6-foot by 3-foot by 2-foot enclosure is recommended for adult tegus, with double that size needed for housing more than one.
Taller cages are not necessary for tegus, unlike some other lizards, since they don't stand on their hind legs or climb trees.
A log or box for hiding should be provided, containing slightly damp sphagnum moss to aid with shedding and humidity.
Argentine tegus love to burrow, so a substrate that's absorbent and easy to clean is essential. Cypress mulch, orchid bark, or eucalyptus mulch are great options, or you can use several layers of paper for ease of cleaning.

Lighting and Heating

Argentine black and white tegus are active during the day, so they need exposure to full-spectrum UVA, and UVB lighting like the sun provides.
Daytime temperatures should be between 80 and 85 degrees Fahrenheit, with a basking spot between 100 and 110 degrees F.
A drastic change in temperature is not acceptable, so use a combination of reptile heat lamps, bulbs, ceramic heat emitters, and heat mats to reach these high temperatures.
Avoid using hot rocks as they can cause severe burns.
Tegus are partially endothermic, meaning they have a body temperature higher than the ambient temperature at nighttime, but only display temperature control during their reproductive season (September to December).
Food and Water
Juvenile Argentine tegus thrive on a diet of gut-loaded crickets dusted with a calcium/vitamin supplement, along with other feeder insects like mealworms and waxworms.
As your tegu grows, you can introduce pinkie mice and eventually adult mice, pre-killed or frozen-thawed, into their diet. Be cautious of fur, as it can cause intestinal impaction.

A variety of fruits and vegetables can be added to the diet of adult Argentine black and white tegus. Canned dog food and eggs can be offered occasionally, but be aware that too much protein can lead to kidney failure.
To prevent accidental bites, feed your tegu their mice in a bowl or with tongs. Providing a large shallow water dish is also essential, as Argentine tegus enjoy soaking when they're not burrowing.
Fresh water should be provided frequently, especially after your tegu has defecated in its water. A large water dish will also help you achieve the ideal 60 to 80 percent relative humidity in your tegu's environment.
Misting the enclosure with water will aid in maintaining the desired humidity level, which can be monitored with a hygrometer.
Behavior and Breeding
Giant Argentine tegus are known for their docile nature, making them a great pet for reptile enthusiasts. They are relatively large compared to other tegus, but their calm demeanor makes them a joy to handle.
Female tegus are slightly smaller than males, and their gender can be determined by examining the vent at the base of the tail. Males have a bulge, while females have a flat vent.
If you're considering bringing a tegu into your home, it's essential to provide a suitable environment. With regular handling from a young age, Argentine tegus can become quite tame.
