Crested Gecko Digging Behaviour

Quick answer: Digging in a crested gecko is most often seen in gravid females searching for a place to lay eggs, and providing a suitable lay box usually redirects the behavior — in non-breeding or male geckos, occasional substrate investigation is normal and not typically a concern.
Most common causeGravid female nesting search
FixProvide a lay box

Persistent digging without a clear nesting context can occasionally reflect an attempt to find a cooler or more humid microspot, which is worth checking if the enclosure's gradient seems off.

Crested Gecko Enclosure: What You Actually Need

A single adult crested gecko needs a minimum 18"x18"x24" front-opening, well-ventilated enclosure — taller matters more than wider since this species is highly arboreal — furnished with cork bark, branches, and dense foliage for climbing.

Crested Gecko Setup Checklist: Everything Before Day One

A complete crested gecko setup needs a tall 18"+ front-opening enclosure, cork bark and branches for climbing, coco fibre/moss substrate, a misting routine to hold 50–80% humidity, and complete CGD powder — no heat lamp is required in most homes.

Crested Gecko Tank Size Guide: By Age

Hatchlings can start in a small (roughly 8"x8"x12") enclosure to make food easier to find, juveniles move up around a few months old, and adults need a minimum 18"x18"x24" vertical enclosure.

Crested Gecko Heating: Why You Probably Don't Need Any

Crested geckos generally do best at normal room temperature, roughly 72–78°F, and can suffer heat stress above about 82°F. Most homes need no basking bulb or heat mat at all — just monitoring during hot weather.

Crested Gecko UVB: Is It Actually Necessary?

Low-level UVB (roughly 5–6% output) is increasingly recommended as good practice, though it isn't strictly mandatory for crested geckos the way it is for a strongly basking desert species — their diet's built-in D3 from CGD covers much of the gap.

Crested Gecko Humidity: Why It Needs to Be High

Crested geckos need roughly 50–80% humidity, achieved through misting once or twice daily, with good ventilation to prevent the dampness from turning stagnant.
