Toxic Foods for Scorpions: What Pet Scorpions Should Never Eat

Scorpions are obligate insectivores, so the biggest nutrition mistake is offering foods that do not match that biology. Pet scorpions should not be fed human foods like chocolate, candy, bread, dairy, fruit, vegetables, seasoned meat, or sugary products. These foods do not provide the prey profile scorpions are adapted to eat, and some ingredients commonly found in human foods, including caffeine, chocolate, and xylitol, are well known toxins in companion animals and have no place in an exotic invertebrate diet.

A second major risk is wild-caught insects. Even if a bug looks harmless, it may have been exposed to lawn chemicals, household pesticides, parasite eggs, or environmental contaminants. Wild prey can also introduce mites or infectious organisms into the enclosure. For most pet parents, the safest plan is to use captive-raised feeder insects such as crickets, dubia roaches where legal, mealworms, or occasional waxworms from a reputable source.

Food size matters too. Prey that is too large can stress or injure a scorpion, and live prey left loose in the habitat may bite a scorpion during a molt. In general, feeders should be smaller than the scorpion’s body length and easy for the species and life stage to subdue. If your scorpion is premolt, newly molted, or refusing food, it is often safer to hold feeding and check in with your vet if the behavior seems prolonged.

Because published veterinary nutrition guidance for pet scorpions is limited compared with dogs and cats, your vet may tailor advice to the species you keep, its age, molt status, and body condition. That is especially important if your scorpion has eaten something unusual or is showing any change in posture, movement, or appetite.

For the unsafe foods in this article, the safest amount is none. Pet scorpions should not be offered human snack foods, sweets, caffeinated products, sugar-free products, dairy, or heavily processed foods as treats. Even when a food is not proven toxic specifically in scorpions, it can still be inappropriate, spoil quickly, attract mites, and upset enclosure hygiene.

A safer feeding approach is to offer appropriately sized live or pre-killed feeder insects on a schedule that fits the species and life stage. Many adult pet scorpions do well with 1 to 3 suitable insects once or twice weekly, while juveniles may need smaller meals more often. Very active species, growing scorplings, and breeding females may need adjustments. Overfeeding can leave the abdomen overly distended and increase leftover prey problems.

If you are unsure whether a feeder is safe, ask your vet before offering it. As a practical rule, avoid anything caught outdoors, anything larger than the scorpion can control safely, and anything that can bite back aggressively. Remove uneaten prey within about 24 hours, and sooner if your scorpion is in premolt or appears stressed.

Fresh water should still be available in a shallow, escape-safe dish when appropriate for the species, along with correct humidity and temperature. Good husbandry often matters as much as food choice when a scorpion seems off.

A scorpion that has eaten an unsafe item may show refusal to eat, unusual weakness, trouble walking, inability to right itself, tremors, prolonged hiding beyond its normal pattern, or sudden death. Some signs are nonspecific, which means they can also happen with dehydration, poor temperatures, molt complications, trauma, or infection. That is why any change after a questionable feeding should be taken seriously.

You may also notice indirect clues, such as regurgitation-like fluid, a foul smell from decomposing food, mites appearing after spoiled food is left in the enclosure, or injuries from prey that was too large or too aggressive. Newly molted scorpions are especially vulnerable because their exoskeleton is soft and they may be injured by live feeders.

See your vet immediately if your scorpion becomes limp, cannot stand normally, has repeated twitching, is attacked by feeder insects, or declines rapidly after exposure to a non-insect food or wild-caught prey. If possible, save the packaging or a photo of what was offered. That can help your vet assess whether the concern is toxicity, trauma, husbandry-related stress, or another problem.

If the issue seems mild, do not keep offering food to “test” appetite. Remove the questionable item, correct enclosure conditions, and contact your vet for guidance on next steps.

Safer options for most pet scorpions are captive-raised feeder insects from reputable suppliers. Common choices include small crickets, dubia roaches where legal, red runner roaches where appropriate, mealworms, and occasional waxworms or other soft-bodied feeders as variety. Prey should be matched to the scorpion’s size, species, and hunting style.

Whenever possible, choose feeders that have been well maintained and gut-loaded before use. While scorpion-specific nutrition research is limited, feeder quality still matters. Healthy feeder insects are generally a better option than random bugs from outdoors or leftover kitchen scraps. Avoid relying too heavily on very fatty larvae as the only food source.

If your scorpion is shy, injured, or in a vulnerable stage, your vet may suggest offering pre-killed prey with feeding tongs rather than leaving active insects in the enclosure. This can reduce the risk of prey bites and make it easier to monitor intake. It also helps keep the habitat cleaner.

For pet parents who want variety, the goal is not “human food treats.” The better strategy is rotating among safe feeder insects and keeping husbandry consistent. If you want to expand the menu, ask your vet which feeders fit your species and local availability.
