About this Fella

Texas Giant Vinegaroon for sale from Big Z's (Mastigoproctus giganteus). Comes with a Spice rating and a care guide, and ships packed for the weather.

Mastigoproctus giganteus (Texas Giant Vinegaroon / Giant Whip Scorpion)

The giant vinegaroon of Texas and one of the biggest whip scorpions in North America. The Texas Giant has heavy crushing pedipalps, a long whip of a tail that reads the dark, and a party trick nothing else on your shelf can match: grab it and it fires a fine mist of vinegar. No venom, no sting, slow and deliberate, and big enough to fill your palm. It digs its own burrow, comes out after dark to hunt, and lives for years. If you have never kept a vinegaroon, start here; if you have, this is the one every other vinegaroon gets compared to. Grab a Texas Giant today and add a living fossil to the collection.

Why do hobbyists keep Mastigoproctus giganteus?

  • Built Big: heavy palps, a long whip and an armored, prehistoric look. These adults are sold at 2 to 3 inches.
  • No Venom, No Sting: the tail is a sensor, not a stinger. The palps can pinch.
  • The Vinegar Trick: a spray of concentrated acetic acid from the base of the tail. It smells like vinegar, stings in the eyes or a cut, and is a great story every time.
  • Long-Lived: 5 to 7 years or more with good care.

How should Mastigoproctus giganteus be kept?

  • Adult Size: up to about 3 inches of body, plus the palps and the whip.
  • Enclosure: a Burrow Buddy, 8 inch cube or 5 gallon with 4 to 6 inches of moist soil and coco, a cork hide, leaf litter, and vents low on two opposite walls.
  • Temperature: 72 to 82 degrees F.
  • Humidity: 65 to 80 percent. One damp side and one drier side.
  • Water: a shallow dish with pebbles in it.
  • Diet: 1/2 to 3/4 inch roaches or crickets every week or two, offered at dusk. Slow metabolism, so do not overfeed.
  • Temperament: calm and slow. Keep handling rare and gentle, keep it away from your face and any cuts, and wash your hands after.

Are there any additional notes or considerations?

  • Wild-Caught: field-collected adults, settled and feeding.
  • Molts Underground: it needs a damp burrow to molt. If it seals itself in, leave it alone.
  • Solo by Default: one per enclosure is the safe way to keep them.
  • Spice Level 2: Beginner. One animal, shipped live on FedEx Overnight. Live Arrival Guarantee on overnight orders.

Full care is in the care guide. It covers enclosure size, temperature, humidity, feeding, molting signs and handling limits for this species. Read the Advanced guide, or the shorter Simple guide →

Couldn't ask for better communication and packaging. I've purchased an insane amount of insects over the years and you can see they take it seriously. From the packaging down to the labeling. Every bit of the purchase and process was flawless.
