Emperor Scorpion Diet Guide: Best Foods, Portions, and Feeding Schedule

⚠️ Caution: feed only appropriate live feeder insects in the right size and amount.
Quick Answer
  • Emperor scorpions are insectivores. In captivity, most do well on appropriately sized live crickets, roaches, mealworms, or occasional waxworms.
  • A practical starting portion for an adult is 2-4 feeder insects per meal, usually 1-2 times weekly. Juveniles often eat more often, such as every 2-3 days.
  • Choose prey no longer than the scorpion's body length, and avoid wild-caught insects because of pesticide and parasite risk.
  • Gut-loading feeder insects for 24-48 hours before feeding can improve nutritional value. Remove uneaten prey within about 24 hours.
  • Typical monthly cost range for feeder insects is about $5-$20 in the US, depending on prey type, quantity, and whether you buy in bulk.

The Details

Emperor scorpions are primarily insect-eaters. In captivity, the safest staple foods are commercially raised feeder insects such as crickets and roaches, with mealworms or superworms used more selectively. Many exotic-animal references recommend live prey because movement helps trigger a feeding response, and feeder insects are commonly improved nutritionally by gut-loading them before use.

Variety matters. Rotating between crickets, dubia roaches where legal, and other captive-raised insects can help reduce the risk of relying too heavily on one prey type. Waxworms are usually better treated as an occasional higher-fat option rather than a staple. Wild-caught insects are not a good choice because they may carry pesticides, parasites, or other contaminants.

Your scorpion may not eat on a strict schedule every week. Appetite often changes with temperature, humidity, molt timing, stress, and age. A scorpion that is close to molting may refuse food for days or longer. That can be normal, but any prolonged fasting, weakness, or husbandry concern is worth discussing with your vet.

Fresh water should always be available in a shallow dish, even though emperor scorpions get some moisture from prey. Good nutrition and good husbandry work together. If enclosure heat, humidity, or hiding areas are off, feeding problems are more likely.

How Much Is Safe?

There is no single perfect portion for every emperor scorpion, so feeding is usually based on size, age, body condition, and appetite. For many adults, a reasonable starting point is 2-4 appropriately sized insects per feeding, offered about once or twice weekly. Juveniles usually need smaller prey and more frequent meals, often every 2-3 days.

A useful rule is to offer prey that is not larger than the scorpion can safely overpower. Many keepers use insects that are about the width of the scorpion's claws or no longer than the body length. If your scorpion consistently leaves food behind, reduce the number offered next time. If it finishes quickly and maintains a lean, healthy appearance, your vet may suggest a modest increase.

Overfeeding can contribute to obesity and poor enclosure hygiene, while underfeeding may lead to weight loss and weakness. Because body scoring in invertebrates is less straightforward than in dogs or cats, it helps to track feeding dates, prey type, and visible changes in body fullness. If you are unsure whether your scorpion is getting enough, bring photos and a feeding log to your vet.

Feeder insect costs are usually manageable. A small home setup may spend around $5-$20 per month on crickets, roaches, or worms, while larger collections or premium feeder choices can run higher.

Signs of a Problem

A skipped meal is not always an emergency, especially if your emperor scorpion is nearing a molt or has recently been moved. Still, feeding problems deserve attention when they last longer than expected or happen along with other changes. Concerning signs include persistent refusal to eat, visible weight loss, weakness, trouble capturing prey, shriveling, dehydration, or unusual inactivity.

You should also watch for husbandry-linked problems that can look like diet issues. A scorpion kept too cool, too dry, or under chronic stress may stop eating. Uneaten prey left in the enclosure can injure a vulnerable scorpion, especially around a molt. If your scorpion is lying awkwardly, cannot right itself, has trouble walking, or seems stuck in a molt, contact your vet promptly.

When to worry more: if a juvenile stops eating, if an adult refuses food for an extended period outside of an obvious premolt phase, or if appetite loss comes with a sunken appearance or enclosure problems. Exotic pets often hide illness well. If something feels off, it is reasonable to check in with your vet early.

Safer Alternatives

If your emperor scorpion does not do well with one feeder type, safer alternatives usually mean switching to another captive-raised insect, not offering human food. Good options to discuss with your vet include gut-loaded crickets, dubia roaches where permitted, red runner roaches if appropriate, and occasional mealworms or superworms. Some scorpions show clear prey preferences, and a small rotation can improve acceptance.

If prey escapes or stresses your scorpion, you can ask your vet whether tong-offered or closely supervised feeding makes sense for your setup. Pre-killed insects are sometimes accepted, but many emperor scorpions respond better to moving prey. Avoid wild insects, fireflies, pesticide-exposed bugs, and oversized prey.

For pet parents trying to keep costs predictable, buying feeder insects in small bulk quantities and maintaining them properly can lower the monthly cost range. Conservative care often means using a simple rotation of common feeder insects and focusing on husbandry basics. Advanced care may include more customized prey rotation, detailed feeding logs, and a consultation with an exotic-animal veterinarian when appetite is inconsistent.

If your scorpion repeatedly refuses food, the safest alternative is not to keep changing foods at random. Instead, review enclosure temperature, humidity, hides, and molt timing, then contact your vet for guidance.
