Overview of the Species

The Arizona bark scorpion (Centruroides exilicauda) is a species of scorpion that is native to the southwestern United States, including Arizona, California, Nevada, and New Mexico. It is one of the most venomous species of scorpion in North America, with a venom that can cause severe pain, numbness, and even death in humans and pets. However, with proper care and caution, Arizona bark scorpions can make fascinating and rewarding pets for those who are willing to take on the responsibility.

Range and Habitat

Arizona bark scorpions are found in a variety of habitats, including desert scrub, grassland, and rocky areas. They are most commonly found in the Sonoran Desert, which stretches across southern Arizona and into parts of California, Nevada, and Mexico. Arizona bark scorpions are nocturnal and can be found hiding under rocks, in burrows, or in trees during the day. At night, they come out to hunt insects and other small prey.

Physical Characteristics

Arizona bark scorpions are small, slender creatures that can grow up to 3 inches in length, including their tail. They have a pale yellow or tan coloration with dark brown or black stripes running down their backs. They have two large pincers, or pedipalps, on their front legs, which they use to capture and crush their prey. They also have a segmented tail that ends in a venomous stinger, which they use to defend themselves from predators and subdue their prey.

Feeding Habits

Arizona bark scorpions are opportunistic predators that will eat a variety of insects and other small prey. In the wild, they may feed on crickets, beetles, grasshoppers, and other insects, as well as small lizards and mice. As exotic pets, they should be fed a diet of crickets, mealworms, and other insects, which can be purchased at a pet store or online.

It is important to dust the insects with a calcium supplement to ensure that the scorpion is getting the nutrients it needs.

Arizona bark scorpions have a low metabolism and do not need to be fed frequently. In general, they should be fed once or twice a week, depending on their size and activity level. It is important to monitor the scorpion’s food intake and to remove any uneaten insects from the enclosure to prevent them from attacking and potentially harming the scorpion.

Lifecycle and Reproduction

Arizona bark scorpions have a lifespan of 3-7 years in the wild and up to 10 years in captivity with proper care. They undergo a process called metamorphosis, in which they go through several stages of development before reaching adulthood. After hatching from eggs, Arizona bark scorpions go through several molts or shedding their exoskeleton, as they grow and mature.

Arizona bark scorpions reach sexual maturity at around 1 year of age. During the breeding season, males will wander in search of a mate and use their pincers and stinger to defend themselves from other males.

After mating, the female Arizona bark scorpion will carry the eggs in a special brood pouch until they hatch, typically after 6-8 weeks. The young scorpions, called scorplings, are independent of birth and will hunt and fend for themselves.


While the Arizona bark scorpion is one of the most venomous scorpions in North America, it is not to be confused with the tailless whip scorpion, which has different habitats and distributions. Learn more about the tailless whip scorpion’s habitats and distributions at desert-scorpions.com.

Caring for Arizona Bark Scorpions as Exotic Pets

Safety Precautions

It is important to remember that Arizona bark scorpions are venomous creatures and can pose a risk to humans and pets if they are not handled properly. If you are stung by an Arizona bark scorpion, seek medical attention immediately. Symptoms of a scorpion sting may include severe pain, numbness, tingling, and muscle twitching. In severe cases, a sting may cause difficulty breathing, tremors, and even death.

To prevent accidents and injuries, it is important to follow these safety precautions when handling Arizona bark scorpions:

  • Wear gloves when handling the scorpion to protect your hands and fingers.
  • Use a long-handled scoop or tongs to move the scorpion or clean its enclosure.
  • Keep the scorpion in a secure enclosure with a secure lid to prevent escape or accidental release.
  • Do not allow children or pets to handle the scorpion or have access to its enclosure.
  • Avoid picking up or handling the scorpion when it is molting or has recently molted, as it is more vulnerable and prone to injury.

Housing and Enclosure Requirements

Arizona bark scorpions are small creatures and do not require a large enclosure. A 10-gallon tank or terrarium is sufficient for one or two scorpions, although larger enclosures may be necessary for a group of scorpions. It is important to provide the scorpion with a secure and escape-proof enclosure, as they are skilled climbers and can easily escape through small openings or gaps. The enclosure should also have good ventilation to allow for proper air circulation.

To create a suitable habitat for your Arizona bark scorpion, follow these guidelines:

  • Use a substrate of sand, soil, or coconut coir to provide the scorpion with a place to burrow and hide.
  • Include hiding spots, such as rocks or cork bark, for the scorpion to retreat to when it feels threatened or wants to rest.
  • Provide a shallow water dish for the scorpion to drink from, but be sure to change the water frequently to prevent it from becoming contaminated or dirty.
  • Maintain a temperature of 70-80°F and a humidity level of 30-50% in the enclosure.
  • Avoid using heat lamps or other heat sources that may dry out the enclosure or cause scorpion stress.</
  • Use a low-wattage, UVB lighting source to provide the scorpion with the necessary UVB rays for proper metabolism and growth.

Diet and Nutrition

As mentioned earlier, Arizona bark scorpions should be fed a diet of crickets, mealworms, and other insects. It is important to dust the insects with a calcium supplement to ensure that the scorpion is getting the necessary nutrients. In addition, it is important to provide the scorpion with a clean and safe environment to prevent stress and illness. This includes keeping the enclosure clean and free of debris, and avoiding overcrowding or overfeeding the scorpion.

My Private Notes

As an exotic pet expert with over a decade of experience, I have had the opportunity to work with and care for a number of Arizona bark scorpions. In my experience, there are a few non-obvious tips that can make a big difference in the health and well-being of these fascinating creatures:

  • Arizona bark scorpions are sensitive to vibrations and can become stressed if their enclosure is constantly being handled or disturbed. To prevent this, try to handle the scorpion as little as possible and avoid placing the enclosure in a high-traffic area.
  • Arizona bark scorpions are opportunistic feeders and will eat almost anything they can catch. This can lead to overfeeding if the scorpion is given too many insects or prey items. To prevent this, monitor the scorpion’s food intake and remove any uneaten insects from the enclosure.
  • Arizona bark scorpions are sensitive to changes in their environment and can become stressed if their enclosure is not kept at a consistent temperature and humidity level. To prevent this, use a thermometer and hygrometer to monitor the conditions in the enclosure and make adjustments as needed.
  • Arizona bark scorpions are prone to mites and other parasites, which can cause illness and stress. To prevent this, regularly inspect the scorpion for any signs of parasites and treat it as necessary. A weekly dusting with an anti-parasite powder can also help prevent infestations.

By following these tips and taking good care of your Arizona bark scorpion, you can provide it with a healthy and stress-free environment and enjoy its fascinating behavior and unique characteristics for years to come.
