Is It Legal to Own an Argentine Tegu? Florida's Prohibited List Explained

Is It Legal to Own an Argentine Tegu? Florida's Prohibited List Explained

Argentine tegus don't have a federal problem. They aren't listed as injurious wildlife, and most states don't mention them in their wildlife codes at all. What they have is a very specific, very real Florida problem, and unlike a lot of exotic-pet rumors, this one is fully phased in with no workaround left. For everything else about keeping one, see our full Argentine Tegu care guide.

Florida's Prohibited List: What Changed and When

On February 25, 2021, the Florida Fish and Wildlife Conservation Commission placed 16 high-risk nonnative reptiles on its Prohibited species list, including all Argentine black and white tegus (Salvator merianae) and all Tupinambis tegus, alongside green iguanas, Burmese and other pythons, green anaconda, and Nile monitors. The acquisition ban took effect April 29, 2021: as of that date, new tegus can no longer be legally acquired as pets in Florida.

If You Already Owned One: The Grandfathering Window

Existing Florida tegu owners had until July 28, 2021 to obtain a free Grandfathered Prohibited Species for Personal Use permit and have their animal PIT-tagged, essentially microchipped, allowing them to legally keep it for the rest of its life. People relocating to Florida with documentation of prior ownership elsewhere could apply under the same provision. That registration window has been closed for years now, there's no current path to grandfather in a tegu acquired after the ban took effect.

Why Florida Specifically

This isn't a precautionary rule aimed at a hypothetical risk. Argentine tegus have established breeding wild populations in multiple Florida counties, including Miami-Dade, Charlotte, Hillsborough, and St. Lucie. They're documented predators of the eggs and nests of native species, gopher tortoises, American crocodiles, and ground-nesting birds among them. This is the same invasive-reptile enforcement pattern that previously drove Florida's restrictions on Burmese pythons, real, established wild populations causing measurable ecological damage, not a rule written in the abstract.

The 2025 Caging Rule Update

A rule refinement effective August 20, 2025 tightened enclosure requirements further: tegus and green iguanas over 9 inches snout-to-vent length must now be housed individually, specifically to prevent breeding, with any eggs produced destroyed immediately. Commercial breeding of tegus by qualifying license holders was only permitted through June 30, 2024, closing off what had been the last legal supply channel for captive-bred tegus sold within the state.

What About Other States?

Tegus aren't listed as federally injurious wildlife, so there's no nationwide restriction working against them the way there is for some large constrictor species. This guide focuses specifically on Florida's restriction because it's the one fully documented, verified rule we found in researching this species. That doesn't mean every other state is automatically clear, a handful of states maintain broader restrictions on nonnative or nondomestic reptiles generally, covered at a higher level in our exotic pet legal hub. Always verify directly with your own state's wildlife or natural resources agency before acquiring one, rules can and do change.
