The eastern box turtle (Terrapene carolina carolina) is a beloved North American reptile known for its high-domed shell, intricate yellow and orange patterns and ability to close up completely inside its shell. Box turtles are intelligent, long-lived and full of personality, but their care is more nuanced than many people realize. This guide covers what they need to thrive and introduces the captive-bred Eastern Box Turtles raised at www.CbReptile.com.

Natural History

Eastern box turtles range across much of the eastern United States, from southern Maine and Michigan south to Georgia and west to Illinois and Tennessee. They inhabit deciduous and mixed forests, meadows, forest edges and areas near streams and wetlands. Despite being turtles, they are primarily terrestrial, wading into shallow water to soak and cool off.

Box turtles have small home ranges and are known for strong site fidelity, often spending their entire lives in an area of only a few acres. They are most active in the morning and after summer rains, and they brumate through the winter by burrowing into soil and leaf litter. Wild populations are declining due to habitat loss, road mortality and collection, so wild box turtles should never be taken from their habitat.

Appearance

The carapace is high and domed, typically brown to black with yellow or orange radiating markings that vary greatly between individuals. The hinged plastron allows the turtle to close its shell completely, protecting the head and limbs. Adult males usually have red eyes, a concave plastron and thicker tails, while females usually have brown eyes and flat plastrons.

Size and Lifespan

Hatchlings are only about 1 to 1.5 inches long. Adults typically measure 4.5 to 6 inches in shell length. Box turtles are remarkably long-lived; with proper care they commonly live 40 to 50 years, and some individuals have been documented to live much longer.

Temperament

Eastern box turtles are curious and observant. Many learn their keepers’ routines and come out to greet them at feeding time. They may close up when startled but usually relax quickly once they feel secure.

Enclosure Setup

Box turtles do best with as much floor space as possible. Glass aquariums are generally not ideal because turtles cannot see the barrier and may constantly try to walk through it. Opaque-sided tubs or tables work far better. A Tortoise & Box Turtle Tub is a great option for juveniles.

• Indoors: at least 4 x 2 feet for a single adult, with larger spaces strongly preferred.
• Outdoors: a secure, predator-proof pen with walls the turtle cannot climb and a barrier that extends below ground is ideal in suitable climates.
• Substrate: a deep, moisture-retaining mix of topsoil, coco coir and leaf litter that allows burrowing.
• Decor: hides such as a Fluker’s half log hide, plants and a shallow water dish large enough for soaking.

Heat, UVB and Humidity

Provide a basking area of about 85 to 90°F, with the rest of the enclosure in the mid to upper 70s. Night temperatures in the upper 60s to low 70s are fine. Use UVB from a linear tube indoors, with shaded areas so the turtle can regulate its exposure. Outdoors, natural sunlight with plenty of shade is best.

Humidity is crucial, ideally 60 to 80 percent. Keep the substrate damp but not waterlogged, mist regularly and provide humid hides. Dehydration and low humidity are common causes of eye and respiratory problems in box turtles.

Diet

Box turtles are omnivores, and variety is key. Juveniles tend to eat more animal protein, while adults shift toward a more balanced diet.

• Animal protein (about 50 percent): earthworms, nightcrawlers, slugs, snails, crickets, dubia roaches and soaked high-quality turtle pellets.
• Plant matter (about 50 percent): dark leafy greens, squash, berries, melon, tomatoes and edible mushrooms.

Feed juveniles daily and adults every day or every other day. Dust food with calcium a few times per week and provide a multivitamin weekly.

Handling

Pick up box turtles with both hands, holding the sides of the shell. Avoid excessive handling, which can be stressful. Always wash your hands afterward, as with any reptile.

Why Captive-Bred Matters

Because wild box turtle populations are declining and individuals have such strong ties to their home ranges, removing them from the wild is harmful. Captive-bred box turtles are healthier, adapt better to captive life and help protect wild populations. If you enjoy box turtles, our 3 Toed Box Turtles are a closely related option. Our captive-bred eastern box turtles are raised by our team, including a staff biologist.

Frequently Asked Questions

Do eastern box turtles need water?

Yes. They need a shallow water dish for soaking and drinking. Keep it shallow enough that the turtle can easily climb in and out.

How long do box turtles live?

They commonly live 40 to 50 years with good care, and some live much longer.

Can box turtles live outdoors?

Yes, in suitable climates with a secure pen, shade, water and a place to burrow and brumate.

Should I keep a wild box turtle I find?

No. Wild box turtles should be left where they are found. Captive-bred turtles are the responsible choice.
