Scorpion Cost vs. Tarantula Cost: Which Arachnid Is Cheaper to Keep?
Scorpion Cost vs. Tarantula Cost
Last updated: 2026-03-14
What Affects the Price?
The biggest cost difference is usually the animal plus enclosure, not day-to-day feeding. Common captive-bred tarantulas often start around $15-$60 for slings or juveniles, though sought-after species can run much higher. Common pet scorpions such as Asian forest scorpions may start around $25, while larger or more established emperor scorpions are often higher. Enclosure costs vary by species and size, but a basic arachnid setup can be modest, while a display-style planted habitat can push startup costs well over $200.
Species needs matter. Many tarantulas do well in smaller, dry or moderately humid enclosures with simple hides and substrate. Scorpions, especially tropical species, often need deeper moist substrate, secure hides, and more attention to humidity. If heat support, extra décor, or moisture-retaining substrate is needed, the setup cost rises. Arboreal tarantulas can also cost more because they need taller enclosures.
Ongoing costs are usually low for both, but feeders, substrate replacement, and equipment upgrades add up over time. Crickets and roaches are inexpensive in small quantities, yet shipping can increase the monthly total if you do not buy locally. Vet care is the wild card. Exotic appointments are not routine for every arachnid household, but if your pet needs an exam for injury, molt problems, dehydration, or a husbandry review, the visit can quickly cost more than the arachnid itself.
One more factor is where you buy. Captive-bred animals often cost more upfront than wild-caught imports, but they may be a safer and more predictable choice. For many pet parents, paying a bit more at the start can reduce stress, losses, and replacement costs later.
Cost by Treatment Tier
Spectrum of Care means you have options. Here are treatment tiers at different price points.
Budget-Conscious Care
- Captive-bred beginner tarantula sling or juvenile, or a young Asian forest scorpion
- Small secure plastic tote or faunarium
- Basic substrate, one hide, water dish
- Small feeder insect purchases as needed
- Spot cleaning and simple home monitoring
Recommended Standard Treatment
- Captive-bred beginner or intermediate tarantula, or a healthy juvenile to adult scorpion
- Glass or acrylic enclosure sized for the species
- Quality substrate, hide, water dish, thermometer/hygrometer as needed
- Routine feeder insects and periodic substrate replacement
- Initial exotic vet exam or husbandry consultation in some areas
Advanced / Critical Care
- Higher-value species, larger adult specimen, or premium captive-bred line
- Display terrarium or planted bioactive-style habitat
- Lighting or supplemental heating when appropriate for the enclosure room and species
- Backup monitoring tools, décor, and premium feeder sourcing
- Exotic vet exam, diagnostics, or treatment if problems arise

How to Reduce Costs
Start with a beginner-friendly, captive-bred species. That one choice can lower both purchase cost and risk. Common terrestrial tarantulas are often the most budget-friendly long-term option because they usually need smaller, simpler enclosures and modest feeding. A tropical scorpion can still be affordable, but humidity management may require a little more ongoing attention.
Buy the enclosure for the actual size and lifestyle of the arachnid, not for what looks impressive on a shelf. Many new pet parents overspend on oversized tanks, extra lighting, or décor that the animal does not need. A secure hide, correct substrate depth, proper ventilation, and species-appropriate moisture matter more than a fancy setup.
You can also save by purchasing feeders locally or setting up a small feeder insect routine at home if your vet or exotic care team feels that is appropriate for your household. Reusing disinfected décor, buying substrate in larger quantities, and avoiding impulse species upgrades can keep annual costs predictable.
If you are unsure about humidity, temperature, or molt support, ask your vet early. A husbandry check before problems develop is often more affordable than replacing an arachnid or paying for urgent exotic care after a preventable issue.
Cost Questions to Ask Your Vet
Bring these questions to your vet appointment to get the most out of your visit.
- Based on this species, what enclosure size and humidity setup are actually necessary?
- Which beginner species tend to have the lowest long-term care costs and the fewest husbandry problems?
- Do you recommend an initial exotic wellness exam for this arachnid, and what is the cost range in our area?
- What warning signs would mean I should schedule a visit right away, such as injury, dehydration, or a bad molt?
- Are there any enclosure items or heating products you do not recommend because they add cost without helping the animal?
- How often should substrate be replaced for this species, and what type is safest and most practical?
- Is there a lower-cost feeder plan that still meets this species' needs?
- If my arachnid stops eating around a molt, when is that normal and when does it become a medical concern?
Is It Worth the Cost?
For many pet parents, tarantulas are usually cheaper to keep than scorpions, especially if you choose a common terrestrial species. Their enclosures are often simpler, their feeder needs are modest, and many beginner species are widely available at approachable cost ranges. That does not mean scorpions are high-cost pets. It means their humidity and substrate needs can make the setup a little less forgiving.
A scorpion may still be the better fit if you prefer a more secretive nocturnal pet and understand that observation, not handling, is the goal. Some pet parents enjoy the natural behaviors, UV fluorescence, and compact footprint enough that the slightly higher setup effort feels worthwhile.
The best value is not the lowest receipt total. It is the species whose care needs match your home, your comfort level, and your budget for feeders, supplies, and occasional exotic vet support. If you want the lowest typical long-term cost, a beginner tarantula often wins. If you are drawn to scorpions, thoughtful planning can still keep costs very manageable.
Before bringing either arachnid home, talk with your vet about local exotic care access. That conversation can help you choose a pet you can realistically support from day one through the years ahead.
