Adult Scorpion Feeding Guide: Portions, Variety, and Frequency

⚠️ Feed with caution
Quick Answer
  • Adult scorpions usually do best on live, captive-raised insects offered about once weekly, though some larger species may eat every 7-14 days depending on body condition and appetite.
  • Offer 1-3 appropriately sized prey items per feeding. A practical rule is to keep prey no longer than the scorpion's body length, and for many species closer to the head-to-mouthpart length is safer.
  • Use variety over time, not all at once. Gut-loaded crickets and roaches are common staples, while mealworms or waxworms are better as occasional variety rather than the whole diet.
  • Remove uneaten prey within 24 hours, and sooner if your scorpion is hiding, stressed, or preparing to molt. Live prey can injure a resting or molting scorpion.
  • A typical monthly cost range for feeder insects for one adult pet scorpion is about $5-$20 in the US, depending on species size, prey type, and whether you keep feeder insects at home.

The Details

Adult scorpions are carnivorous invertebrates that usually eat live insects in captivity. Most pet parents do well with a simple plan: offer captive-raised prey at night, keep portions modest, and adjust based on your scorpion's size, species, and body condition. Healthy adults often eat less often than juveniles, so a weekly schedule is common, while some larger adults may only need food every 10 to 14 days.

Good staple feeders include gut-loaded crickets and appropriately sized roaches. Hornworms can add moisture and variety, while mealworms are better as occasional rotation items because they are not ideal as the only feeder. Wild-caught insects are not a safe choice. They may carry pesticides, parasites, or other contaminants that can harm your scorpion.

Feeding behavior can vary a lot. Some adults are enthusiastic eaters, while others may refuse meals for days or even longer, especially before a molt. That does not always mean something is wrong. Appetite is closely tied to temperature, humidity, stress, and access to secure hiding areas, so husbandry problems can look like feeding problems.

A shallow water dish should still be available at all times, even if you rarely see your scorpion drink. Clean it daily and keep it shallow enough to reduce risk for smaller or weakened animals. If your scorpion stops eating and also seems weak, injured, or unable to molt normally, contact your vet.

How Much Is Safe?

For most adult pet scorpions, start with 1 to 2 prey items once a week. Larger adults may take 2 to 3 large crickets or similar-sized roaches every 7 to 14 days. If your scorpion is small-bodied or sedentary, one prey item may be enough. If it is a larger species with a strong feeding response, a slightly bigger meal may be reasonable. The goal is a steady routine, not a packed feeding schedule.

Prey size matters as much as prey number. A safe rule is to choose insects no longer than the scorpion's body length, and many keepers use even smaller prey for easier capture. Oversized prey can be refused, stress the scorpion, or in some cases injure it. If you are unsure, choose the smaller feeder and offer another only if the first is taken readily.

Do not keep adding food because your scorpion will take it. Overfeeding can lead to an overly swollen abdomen and may make movement and molting harder. If the abdomen looks very full, scale back to every 10 to 14 days and discuss body condition with your vet if you are concerned. Also pause feeding during pre-molt and wait until the new exoskeleton has hardened after a molt before offering prey again.

For budgeting, feeder insects for one adult scorpion commonly run about $5-$20 per month. Buying small batches of crickets may cost less up front, while keeping roaches or buying mixed feeders can improve variety but may raise the monthly cost range.

Signs of a Problem

A missed meal is not automatically an emergency in an adult scorpion. Many adults eat intermittently, and appetite often drops before a molt. Still, feeding changes deserve attention when they happen along with other problems such as a shrunken or wrinkled appearance, trouble walking, inability to grasp prey, visible injury, mites, or a bad molt.

Watch for prey being ignored repeatedly despite correct temperatures and humidity, a very thin body, persistent lethargy outside normal daytime hiding, or an abdomen that looks dramatically overfilled. Uneaten insects left in the enclosure can also become a problem because they may stress or injure a vulnerable scorpion, especially during molt.

Molting is a special situation. Refusal to eat, reduced activity, and increased hiding can be normal before a molt. Do not force feeding. If your scorpion seems stuck in molt, has bleeding, cannot right itself, or remains weak after molting, see your vet promptly.

Contact your vet sooner if your scorpion has gone off food and also shows collapse, severe dehydration, obvious trauma, parasites, or husbandry concerns you cannot correct. In invertebrates, small problems can become serious quickly when hydration, enclosure safety, or molting is affected.

Safer Alternatives

If your scorpion is bored with one feeder or has trouble catching fast prey, safer alternatives usually mean changing the feeder type, size, or presentation rather than changing away from insects. Gut-loaded crickets and roaches are the most practical staples for many adults. If prey tends to burrow before your scorpion can catch it, tong-feeding or offering prey in a smooth-sided feeding area may help.

For variety, you can rotate in hornworms or mealworms occasionally. Waxworms can be used sparingly as a treat, not a staple. Pre-killed prey placed near the hide may work for some scorpions, especially shy individuals, but many adults respond best to live movement. Avoid wild insects, fireflies, and any feeder from an unknown source.

If your scorpion regularly refuses food, look at the setup before changing the menu too much. Inadequate heat, poor humidity, too much disturbance, or lack of hiding places often suppress appetite. Correcting husbandry may be more helpful than buying more feeder types.

You can ask your vet whether your scorpion's species has any special feeding patterns, whether its body condition looks appropriate, and whether a fasting period seems normal or concerning. That is especially helpful if your pet parent goals include conservative care, a predictable monthly cost range, or support during a molt.
