Hadrurus spadix is a large (around 15 centimetres (5.9 inches)) scorpion native to the southern deserts of North America.

The substrate should be humidified in order to stabilize it and permit burrowing, then dried before introducing the scorpion in the vivarium.

A rock or a piece of bark should be provided so the scorpion can dig its burrow under it.

No water is needed in the vivarium and humidity should be quite low (30%) to prevent mycosis.

As with all scorpions, this species can be fed most types of small insects, though crickets remain the most common choice.
