Scorpion Not Eating
Food refusal is one of the most common concerns for scorpion keepers, and in most cases it is not a sign that something is wrong. Scorpions are adapted to go extended periods without food and will routinely refuse meals for reasons that have nothing to do with illness. Working through the likely causes systematically is almost always more useful than assuming the worst.
Most Common Causes
Pre-molt
The most common reason a juvenile or sub-adult scorpion suddenly stops eating is that it is approaching a molt. Scorpions typically refuse food in the days to weeks before molting. If your scorpion has been eating consistently and then abruptly stops — particularly if it is also spending more time burrowed or sealed in its hide — pre-molt is the most likely explanation.
What to do: remove all live prey from the enclosure immediately and leave the animal alone. Do not attempt to force-feed. See the Scorpion Molting Guide for full pre-molt and molt guidance.
Post-molt recovery
Scorpions commonly refuse food for 1–2 weeks after a molt while the new exoskeleton hardens. This is normal. Do not offer prey until the exoskeleton has visibly darkened and hardened. Offering prey too soon after a molt risks injury to the animal.
Temperature too low
Scorpion metabolism is temperature-dependent. An enclosure running below the appropriate temperature range will result in reduced appetite or complete food refusal. Check temperatures with a reliable thermometer — not just the heat source's dial — and correct before assuming a feeding problem exists.
Recent stress or disturbance
Scorpions that have recently been transported, had their enclosure rearranged, or been handled may refuse food for days to weeks while they settle. Give the animal time and minimize disturbance.
Prey size or type
Offer appropriately sized prey that the scorpion can overpower easily. If food is repeatedly refused, try a smaller feeder or a different feeder type.
Seasonal or cyclical variation
Some scorpions eat less during cooler months or go through natural periods of reduced appetite. This is more common in species from environments with seasonal variation and is not necessarily a husbandry problem.
Satiation
A scorpion that has recently eaten a large meal may refuse food for longer than usual. This is normal.
What to Check
- Is the scorpion a juvenile or sub-adult? Pre-molt is the most likely cause.
- Has the scorpion recently molted? Post-molt refusal is normal for 1–2 weeks.
- What is the enclosure temperature? Verify with a thermometer.
- Has anything changed recently — transport, enclosure rearrangement, handling?
- Is the prey appropriately sized and easy for the scorpion to overpower?
- When did the scorpion last eat, and how much?
How Long Is Too Long?
Healthy scorpions can go weeks or longer without eating, particularly around molts or during periods of reduced activity. Extended food refusal in an adult scorpion that is otherwise behaving normally — active at night, responsive, not showing physical signs of decline — is usually not an emergency. However, if refusal is accompanied by visible weight loss, a shriveled appearance, lethargy beyond normal resting behavior, or other physical changes, it warrants closer attention.
When to Be Concerned
Food refusal alone is rarely an emergency. Be more concerned if you also observe:
- Shriveled or sunken appearance — possible dehydration
- Difficulty moving or unusual posture
- Visible injury or abnormality
- Refusal persisting well beyond a normal molt recovery period in a juvenile
If you observe these signs alongside food refusal, see Common Scorpion Health Problems and consider consulting an exotic-animal veterinarian experienced with invertebrates.
What Not to Do
- Do not force-feed
- Do not leave live prey in the enclosure unattended — it can injure the scorpion
- Do not repeatedly disturb the enclosure trying to stimulate feeding
- Do not assume illness without ruling out the common causes above
