01 · Housing

Enclosure & housing

Terrestrial geckos from arid southern African plains and desert edges. Provide hides, basking platforms, rocks and branches, a wet box with damp moss (they dig to damp sand layers in the wild), artificial foliage, dry substrate, and a clear temperature gradient. Adult minimum for a single gecko is 24″ × 18″ × 18″.

Adult minimum size

24″ W × 18″ D × 18″ H

Wooden vivarium for a single adult, or larger. Dry terrestrial setup with heat bulb, T5 12% UV, wet box, rocks and platforms — morning drip drinks preferred over a large bowl.

Decor

  • Hides for seclusion — they dig and use tunnel systems in the wild
  • Basking platforms, rocks and branches for comfort and interest
  • Wet box with damp moss — replicates damp sand layers for tunnels and helps with shedding
  • Artificial foliage for a pleasing, naturalistic look
  • Optional small water bowl only — morning drip drinks preferred (keep humidity low)

Substrate

  • Dry substrate — pelleted straw bedding or coarser desert sand
  • Avoid fine mineral sands that can cause impaction

Cleaning

  • Daily: spot clean to limit bacteria and odours
  • About every six weeks: full clean if kept relatively clean — replace substrate, disinfect decor and vivarium

02 · Climate

Temperature & UVB

Dry heat with a clear cool-to-warm gradient and a ~110 °F basking spot, T5 12% UV, and a wet box for shedding rather than high ambient humidity.

Daytime temperature gradient

When the heat bulb and thermostat sensor are placed as instructed, a probe target of 84–86 °F (29–30 °C) creates this spread. The probe point is not the basking spot.

Daytime temperature gradient by zone, plus night drop
Zone Temperature
Cool side ~80 °F (~27 °C)
Probe point (thermostat probe target) 84–86 °F (29–30 °C)
Middle 88–90 °F (31–32 °C)
Warm side ~100 °F (~38 °C)
Basking spot ~110 °F (~43 °C)
Night drop Reduce thermostat by ~74 °F (~23 °C) at night · ~10 °F drop

Photoperiod & night

  • Winter: 12 hours light/heat
  • Summer: up to 16 hours
  • Night: reduce thermostat by ~10 °F (~6 °C) to approx. 74 °F (~23 °C)
  • Night drop lets metabolism slow — essential for the lizard

UVB lighting

  • T5 UV at 12% — essential equipment on this sheet
  • Mount on the ceiling of the vivarium
  • Match UV on/off to the heat schedule
  • Replace the tube every 12 months — UV output drops even if it still glows
  • Heat about 12 hours in winter and up to 16 hours in summer

  • T5 12% UV unit — ceiling-mounted as recommended on the care sheet; UVA supports appetite & activity; UVB enables vitamin D3 / calcium absorption
  • Heat dome — warm side; same on/off routine as UV (morning on, evening off)
  • Photoperiod — 12 hours in winter, up to 16 hours in summer
  • Replace UV every 12 months — output degrades even if the tube still glows

Dry species · wet box

  • Main enclosure is dry — pelleted straw or coarser desert sand (not fine sand)
  • Add a wet box with damp moss — wild tunnel systems reach damper sand; extra humidity helps shedding
  • Morning drip drinks preferred; optional small bowl only if used carefully so humidity stays low
First power-up tip

Always have the thermostat dial turned down before you plug it into the mains for the first time. Set the probe to 84–86 °F (29–30 °C) for daytime once the heat bulb and sensor are in place.

03 · Nutrition

Diet & feeding

Insects and plant matter as described on this sheet. Dust every feed and use the plant Ca:P lists for variety.

Plant matter

As described on this sheet

  • Leafy greens and weeds (see plant lists)
  • Safe garden herbs and flowers
  • Alternate items for calcium-to-phosphorus balance
  • Dust every plant and insect feed

Live food

With plant matter

  • Insects form part of the diet alongside plant matter
  • Always gut-load feeders well
  • Dust every feed with 4:1 calcium : Nutrobal

Supplements — every feeding

Dust every feeding with a 4:1 mix of calcium : Nutrobal (4 parts calcium to 1 part Nutrobal). Store the mix in an airtight container and use it to coat food every time you feed.

Settling in — appetite

New lizards often will not eat well for the first few days. This is perfectly normal. Once settled and happy, appetite usually increases. Offer insects and plant matter as described on this sheet.

Water & hydration

  • Rarely drink from bowls — we often omit water bowls
  • Offer a morning drink by dripping water on the nose (spray bottle or syringe) until they stop licking
  • Weekly bath — chest-height warm water for about 10 minutes; gentle head dunks often prompt a long drink
  • Reptisafe or bottled water only

Optional bowl

  • If you use a bowl, keep it small so they cannot splash and raise humidity
  • Excess humidity from large bowls can be dangerous for this dry-climate species

Gut-load insects before offering any live food — variety matters for calcium-to-phosphorus (Ca:P) and vitamins.

Why gut loading matters

Feeder insects must be well fed before offering. In the wild, lizards eat insects that themselves ate a wide variety of foods — providing complete nutrition and a better calcium-to-phosphorus (Ca:P) ratio.

  • Use commercial gut-load foods with quality ingredients
  • Add fresh reptile-safe vegetables for variety
  • A single piece of carrot or potato is not enough — poor Ca:P and limited vitamins/minerals

Speak to a member of staff for more feeding advice.

Plant matter & Ca:P lists Supermarket, garden plants, and foods to avoid

This sheet includes plant-matter lists alongside insect feeding. Use as many listed foods as possible and alternate for calcium-to-phosphorus balance. Naturally growing weeds and herbs are excellent when safe.

Good calcium to low phosphorus (examples)

Apricots, basil, blackberries, bok choy, broccoli tops, cantaloupe, carrots/carrot tops*, chicory, Chinese cabbage, clover, dandelion leaves and flowers, escarole, figs and fig leaves, green onion, leeks, okra, oranges, papaya, parsley, pea pods (not peas), rosemary, sow thistle, turnip greens, watercress, continental lettuces (romaine, cos, frisée, endive, radicchio, lollo rosso), mulberry, grape, ficus, rose, hibiscus, and opuntia cactus leaves. *Carrots/carrot tops not in high concentration (tannins).

Marginal Ca:P

Apple (no pips), aubergine, celery leaf only, pears, radish, sweet potato.

Poor Ca:P / high phosphorus — use sparingly

Asparagus, broccoli, Brussels sprouts, cabbage, cauliflower, cucumber, grapes, peaches, plums, squash, strawberries, tomato.

Generally exclude (oxalates / goitrogens / similar concerns)

Beans, rhubarb, spinach, beet greens, Swiss chard, cauliflower, cabbage, mustard greens, peas, collard greens, soy meal/beans, banana.

Garden plants often listed as safe

Carnations/dianthus, dracaena, echeveria/succulents, ficus, geranium, grape (Vitis), hibiscus, impatiens, maple leaves, nasturtiums, oregano, petunia, phlox, pinks, rose petals, soleirolia, viola/pansy/violets (not African). Always double-check any plant before offering.

Toxic / avoid

Apple bark/leaves/seeds, burdock, buttercup, cherry, clematis, crocus, daffodil, eggplant, elderberry, holly, horse chestnut, hyacinth, hydrangea, iris, lily of the valley, mistletoe, narcissus, oak, oleander, peach, peony, poinsettia, potato, primrose, privet, rhododendron, shamrock, snowdrop, sorrel, sweet pea, tomato plant, tulip, Virginia creeper — and some rosemary/sage varieties (verify before use).

Always dust plant and insect foods with the 4:1 calcium : Nutrobal mix.

04 · Behaviour

Handling & behaviour

Patience first. Settling and regular feeding come before handling.

  1. Step 1

    Settle first

    Allow the lizard to settle and begin eating regularly before handling — we recommend at least two successful feeds first. Adapting is stressful; early handling can make it worse.

  2. Step 2

    Short sessions

    Initial sessions: 5–10 minutes only. Lengthen as the lizard becomes more comfortable.

  3. Hygiene

    Wash hands

    Always wash or disinfect hands before and after handling to prevent bacteria transfer both ways.

  4. Warning

    No aerosols

    Do not use aerosols or plug-in air fresheners near the enclosure — the chemicals can harm your lizard.

05 · Welfare

Health & welfare

Prevention starts with correct husbandry — heat, UVB, hydration, and supplementation working together.

Best prevention: good husbandry

Correct temperatures, supplementation, hydration, and UVB keep the immune system and gut working well — supporting essential physiological processes.

Inert substrates Paper, lino, carpet — pros & cons

Pros

  • Lower impaction risk

Cons

  • Limit natural behaviours such as digging
  • Remove natural digging behaviour
  • Can increase faecal contamination (waste less absorbed; insects may contact waste)

Questions

FAQ

What size vivarium does a Giant Namibian Ground Gecko need?

Adult minimum for a single gecko is a 24″ × 18″ × 18″ wooden vivarium, or larger. They are a dry terrestrial species — use pelleted straw or coarser desert sand (not fine sand), add hides, basking platforms, rocks and branches, a wet box with damp moss (they dig to damp sand layers in the wild and need that humidity for shedding), and artificial foliage. Use a heat bulb with the ¼/¼ probe method and a T5 12% UV unit on the ceiling.

What temperatures does a Giant Namibian Ground Gecko need?

Set the thermostat probe to 84–86 °F (29–30 °C) by day with the heat bulb about one-quarter from one side and the probe one-quarter from the opposite side, hanging down the back a few inches from the floor. That creates a gradient of about 80 °F cool, 88–90 °F middle, around 100 °F warm, and a basking spot of about 110 °F under the bulb. At night reduce the thermostat by about 10 °F to around 74 °F (23 °C).

What UV and photoperiod do they need?

Use a T5 UV system at 12% mounted on the ceiling. Match UV on/off to heat. Daytime heat about 12 hours in winter and up to 16 hours in summer when days are longer. Replace the T5 tube every 12 months — UV output drops even if the tube still glows.

How should they drink and stay hydrated?

They rarely drink from water bowls, so bowls are often omitted. Offer a morning drink by dripping water onto the nose with a spray bottle or syringe until they stop licking. You can also give a weekly bath in chest-height warm water for about 10 minutes; gentle head dunks often prompt a long drink. Use Reptisafe-treated or bottled water only. If you use a bowl, keep it small so they cannot splash and raise humidity.

When can I start handling my Giant Namibian Ground Gecko?

Allow the gecko to settle and begin eating regularly before handling — at least two successful feeds first. Early sessions 5–10 minutes only; lengthen as they become more comfortable. Always wash or disinfect hands before and after. No aerosols or plug-in air fresheners near the enclosure.
