01 · Housing
Enclosure & housing
Burrowing setup from drier southern USA habitats: ground area over height, deep coir dig, cork hides, a small shallow water bowl, and a heat mat on the back or side.
Adult minimum size
12″ W × 8″ D × 8″ H
Burrowers need more ground area than height. Glass, plastic or acrylic — various shapes and designs work.
Substrate
- Humidity-retentive coir or coir + sand
- A few inches depth so they can dig if they wish
- Light spray — slightly moist dig pockets, not waterlogged
Cleaning
- Daily: spot clean to keep the environment fresh and limit bacteria
- Every 4–6 weeks: full clean if kept relatively clean — replace substrate, disinfect decor and enclosure

Heat mat & thermostat
Mat on back or side · mat-stat · ~78–80 °F day · drop to ~68 °F night
- Mat — along the back or side of the enclosure
- Control — mat-stat thermostat required
- Day — about 78–80 °F (26–27 °C)
- Night — drop to about 68 °F (20 °C)
02 · Climate
Temperature, humidity & water
Mild heat-mat control, light spray for night humidity, and a small shallow bowl of treated water — heat mat only (no UV required).
Daytime warm end & night drop
When the heat bulb and thermostat sensor are placed as instructed, a probe target of 78–80 °F (26–27 °C) warm end creates this spread. The probe point is not the basking spot.
| Zone | Temperature |
|---|---|
| Cooler side | Away from mat (Gradient) |
| Warm end (mat) (thermostat probe target) | 78–80 °F (26–27 °C) |
| Night drop | Reduce thermostat by ~68 °F (20 °C) at night · mat-stat drop |
Heat
- Supplementary heat unless home is very warm
- Heat mat on back or side + mat-stat
- Day ~78–80 °F · night ~68 °F
Humidity
- Light spray — keep overall humidity low
- Night average 60–70%
- Coir holds slightly moist dig pockets (Arizona / Mexico style)
- No UV required — heat mat only
Climate diagram
Humidity & water
Light spray · night ~60–70% · small shallow bowl · treated water only
- Light spray — maintain low humidity; night average 60–70%
- Small shallow bowl — always present
- Substrate — humidity-retentive coir (or coir + sand) for slightly moist dig pockets
- No UV — heat mat only
Water safety
- Small shallow water bowl always available
- All water (spray and bowl) treated with a reptile-friendly dechlorinator
03 · Nutrition
Diet & feeding
Live insects sized to the animal — feed less often as they mature, and watch the abdomen.
At a glance
Feeding cheat sheet
- Prey
- Live insects — crickets → locust, Dubia · occasional wax worm as adults
- Frequency
- Young 2–3× / week · juveniles 1× / week · adults every other week
- Size
- Prey appropriate to the vinegaroon’s size
- Rule of thumb
- Thin abdomen → feed more · round abdomen → feed less
Livefood progression
Livefood progression
- Younger animals — smaller crickets
- Adults — locust, Dubia
- Occasional wax worm as adults
After a feed or moult
Welfare checks
- Remove uneaten food after 24 hours
- After moult — wait 1 week before feeding
- Lets the exoskeleton harden fully
04 · Behaviour
Handling & behaviour
Harmless to people, but fragile — handle with great care if at all.
- Defence
No venom or stinger
Completely harmless to humans in that sense. Defence is a mist of acetic acid (vinegar-type substance) to deter predators — wash hands after handling.
- Care
Fragile antennae-legs
They can be handled, but are quite fragile — antennae-formed legs damage easily. Handle only with great care.
- Hygiene
Wash hands
Always wash or disinfect hands before and after handling.
- Warning
No aerosols
No aerosols or plug-in air fresheners near the enclosure — the chemicals can be harmful.
05 · Welfare
Health & welfare
Correct mild heat, diggable coir, safe water, sensible feeding, and regular cleaning keep vinegaroons thriving.
Best prevention: good husbandry
Heat-mat control on a mat-stat, light spray for night humidity about 60–70%, a few inches of coir for digging, cork hides, treated water in a small shallow bowl, and daily spot cleaning keep giant vinegaroons healthy.
Questions
FAQ
What size enclosure does a giant vinegaroon need?
Adult minimum is 12″ wide × 8″ deep × 8″ tall. They are burrowers, so ground area matters more than height. Use glass, plastic or acrylic. Provide a few inches of coir or coir + sand for digging, cork bark hides or branches to hide under, a small shallow water bowl, and a heat mat on the back or side on a mat-stat.
How do I heat a giant vinegaroon setup?
They need supplementary heating unless your home is already very warm. Place a heat mat along the back or side of the enclosure on a mat-stat. Set about 78–80 °F (26–27 °C) by day and drop to about 68 °F (20 °C) at night.
What humidity do giant vinegaroons need?
They come from drier southern USA habitats (Arizona / Mexico) but dig into slightly moist pockets. Use humidity-retentive coir (or coir + sand), spray lightly to keep humidity low overall, and aim for about 60–70% average night-time humidity. All spray and bowl water should be treated with a reptile-safe dechlorinator.
What do giant vinegaroons eat?
A variety of livefood sized to the animal: smaller crickets when young, progressing to locusts, Dubia, and the occasional wax worm as adults. Youngsters 2–3 times a week, juveniles once a week, full adults every other week. If the abdomen looks thin, feed more; if round, feed less. Remove uneaten food after 24 hours. After a moult, wait a week before feeding so the exoskeleton can harden.
Can I handle a giant vinegaroon?
They can be handled carefully, but they are fragile — antennae-formed legs damage easily. They have no venom or stinger; defence is a mist of acetic acid (vinegar-type substance), so wash hands after handling. Always wash or disinfect hands before and after. No aerosols or plug-in air fresheners near the enclosure.
