Tarantula habitat design and shelter

For tarantulas. Jumping spiders, orb-weavers and other arachnids need different care guidance.

Plan shelter, substrate and climbing space for your tarantula’s way of life, while keeping routine care as undisturbing as possible.

Plan for the species you keep

A tarantula needs a usable retreat and suitable substrate, even when that means it spends much of its time out of view. Record its scientific name, life stage and approximate size, and establish whether it mainly lives on the ground, in a burrow or above ground.

Check temperature, moisture and enclosure requirements for that species. The Royal Veterinary College distinguishes furnished vertical housing for tree-dwelling tarantulas from arrangements that limit falls for ground-dwelling species. Its guidance also covers secure closures, retreats and the risk of feet catching in mesh.

Provide the right structure

For a ground-dwelling tarantula, plan the floor and shelter first. Avoid long drops onto hard furnishings. A low retreat you can inspect may be more useful than a tall decorative structure.

For a burrowing species, leave enough suitable substrate for a working burrow. Secure heavy features so excavation cannot undermine them, and keep bulky backgrounds from taking up the required digging space.

For a tree-dwelling species, provide upright support, shelter and places to attach webbing. Position service openings so routine access is less likely to damage the main retreat, and keep water within practical reach for maintenance.

Consider how the tarantula may move substrate or extend its web. A fixed decorative opening may not meet all of its retreat-building needs.

Understand the research limits

Stalter and colleagues’ preliminary 2024 study compared standard housing with larger, more complex housing for 15 Brazilian black tarantulas (Grammostola pulchra). The animals used more area and responded differently to a new environment, but overall inactivity was similar and they showed no clear housing preference. Because size and structure changed together, the study cannot isolate the effect of a particular feature.

Earlier laboratory research with young Psalmopoeus cambridgei also reported behavioural differences between enriched and unenriched housing. The species and setting limit how those findings apply elsewhere. Neither study establishes that frequent new objects or rearrangements improve welfare for all tarantulas.

Make care possible with little disturbance

Keep the retreat accessible for necessary intervention, while leaving it undisturbed during routine observation. Place dishes where you can service them without reaching through the usual resting area. Make it possible to remove food remains and check conditions without rebuilding the enclosure.

During a suspected moult, avoid optional layout changes or attempts to make the animal move. Follow species-specific advice on prey removal and when to resume feeding. Injury or an uncertain change in condition calls for an exotics veterinarian with invertebrate experience; immobility alone should not be treated as boredom.

Check the finished layout

Inspect closures, vents, service holes and panel edges for escape routes at the tarantula’s current size. Avoid narrowing cavities and openings you cannot inspect. Check the fall below every climbable surface, including the enclosure walls.

Keep the required temperature, moisture and ventilation achievable after furnishing. Water changes, cleaning and observation should be possible without destroying the main retreat. Exact temperatures, humidity and enclosure proportions must come from care guidance for the species.
