Discoid Roaches for Pet Scorpions: A Feeding Guide

Scorpion Metabolism Is Slow

Pet scorpions—whether you're keeping an emperor scorpion, an Arizona bark scorpion, a deathstalker, or any other species—have a fundamentally different metabolic rate than most reptiles and many other invertebrates. Scorpions are sit-and-wait predators from arid and semi-arid environments. They conserve energy, move slowly, and can go extended periods without food. A scorpion that hasn't eaten in a month isn't starving; it's just being a scorpion. This slow metabolism shapes every aspect of their feeding regimen, including portion size and frequency.

Because of this, scorpions don't need frequent meals. While a young tarantula might eat every few days, a scorpion might eat once a week, once every two weeks, or even less frequently depending on its age, species, and individual appetite. This makes discoid roaches an ideal feeder—you're feeding small portions at long intervals, which matches scorpion biology perfectly.

Sizing Roaches for Different Scorpion Species

Scorpion size varies enormously across species. Emperor scorpions, among the largest, have body lengths up to 8 inches or more. Arizona bark scorpions are tiny—maybe 2 to 3 inches. For small to medium scorpions, Small discoid roaches (1/4 to 1/2 inch) are ideal. For large species like emperors, Medium roaches work well. The general rule is to offer a roach roughly one-third to one-half the length of the scorpion's body (not leg span, but the actual body length from head to tail tip).

Oversizing prey is less risky with scorpions than with some other animals because scorpions use venom to subdue and partially digest prey before consumption. However, a roach that's too large might not be caught effectively, especially if your scorpion is a slow or reluctant hunter. When in doubt, go smaller—a scorpion will eat multiple appropriately-sized roaches over time more reliably than struggling with an oversized single prey item.

Feeding Frequency for Pet Scorpions

Adult scorpions typically do well on a feeding schedule of once every 7 to 14 days. Some species or individuals might stretch this to once every two weeks or even longer. Younger scorpions or juveniles can be fed slightly more frequently—every 5 to 7 days—as they're growing and have higher nutritional demands. Watch your scorpion's body condition. A well-fed scorpion has a plump abdomen. A thin, shrunken abdomen suggests it needs more food or more frequent meals.

Experiment to find the schedule that works for your individual scorpion. If you're offering weekly meals and the scorpion is refusing food, you're probably feeding too frequently—back off to every 10 days or every two weeks. If it's consistently cleaning up meals and seeming eager, you might increase frequency slightly. Many keepers find that once every 7 to 10 days is the sweet spot that keeps scorpions well-nourished without overfeeding.

Discoid Roaches Are Non-Aggressive Prey

One major advantage of discoid roaches for scorpion feeding is their docile nature. Unlike some insect prey—certain crickets, for example—discoid roaches don't bite, don't make noise, and don't act defensively. They won't threaten your scorpion or cause stress in the enclosure. For a slow, deliberate predator like a scorpion, non-aggressive prey is ideal. The roach won't wound the scorpion while the scorpion is working to subdue it. The feeding sequence unfolds calmly, and both animals remain unharmed.

This is particularly important for species like emperor scorpions, which are generally docile but can be stressed by aggressive prey. Discoid roaches allow for a feeding experience that's as low-stress as possible in captivity.

Pre-Crushing Legs for Stubborn Hunters

Some scorpions are enthusiastic, active hunters. Others are slower to respond, particularly as they age. If your scorpion is ignoring live roaches or seems reluctant to hunt, pre-crushing or pre-stunning the roach can help. Gently crush the roach's legs or stun it by chilling (place it in a small container in the fridge for a few minutes) to make it less mobile and easier for a sluggish scorpion to catch and subdue.

This approach keeps the roach alive but immobilized, which some scorpions prefer over fully dead prey. Others will refuse pre-crushed roaches but readily take fresh live ones. Trial and error with your individual scorpion will tell you which approach works best. If your scorpion consistently ignores live roaches, try pre-crushing—it often makes the difference between successful feeding and a frustrated scorpion.

Managing Feeding in the Enclosure

Most keepers feed scorpions directly in their permanent enclosure rather than transferring them. Place a live roach in the enclosure near the scorpion or in its favored resting area. Depending on the species and individual, the scorpion might attack immediately or wait for the roach to move closer. Some scorpions hunt actively; others are ambush predators that wait for prey to approach. Let the scorpion do what comes naturally.

After offering a roach, observe for 30 minutes to an hour. If the scorpion has taken the roach, you're done. If the roach is still moving and the scorpion shows no interest, remove the uneaten roach to prevent it from dying in the enclosure and creating waste or odor. A scorpion that refuses a roach might not be hungry, might be in a pre-molt phase, or might simply not be interested that day. Try again in a few days.

Molt Cycles and Feeding Pauses

Like tarantulas and other arthropods, scorpions molt as they grow. During a molt, the scorpion is vulnerable and shouldn't be offered food. Signs of an impending molt include reduced activity, a dull appearance, and often a period where the scorpion stops eating. If your scorpion hasn't eaten in over two weeks, it might be preparing to molt. Stop offering food and wait. After the molt, wait at least one week before offering food again—the scorpion's exoskeleton needs time to harden and its venom (and digestive system) to regenerate.

Roach Nutrition and Variety

Discoid roaches, with their 20% protein, 7% fat, and balanced calcium-to-phosphorus ratio, provide complete nutrition for scorpions. Many keepers feed roaches exclusively and maintain healthy, long-lived scorpions. Varying prey occasionally—mixing in crickets, grasshoppers, or other arthropods—adds diversity, but it's not necessary. Discoid roaches alone can sustain a scorpion for its entire lifespan. All Angles Creatures' roaches come gut-loaded, meaning they arrive packed with nutrition and hydration that passes directly to your scorpion.
