How Long Do Mourning Geckos Live?
| Typical lifespan | 5–8 years |
| Biggest lifespan factor | Diet quality (complete MRP) |
A long-lived small reptile
With correct diet (a complete MRP as the base) and stable humidity and temperature, mourning geckos routinely reach 5–8 years, which is longer than many similarly sized popular pet reptiles and worth factoring into the decision to get one.
What most affects lifespan
The biggest factors are diet quality (a complete MRP versus an incomplete homemade or insect-only diet), avoiding heat stress from excessive temperatures, and maintaining correct humidity to prevent chronic stress and shedding problems.
Long-term planning
A 15–20 year commitment is worth genuinely considering before buying — this is a pet that may outlast several other life changes, not a short-term novelty animal.

A single adult mourning gecko needs a minimum 12"x12"x18" 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.
A complete mourning gecko setup needs a tall 18"+ front-opening enclosure, cork bark and branches for climbing, coco fibre/moss substrate, a misting routine to hold 60–80% humidity, and complete MRP powder — no heat lamp is required in most homes.
Hatchlings can start in a small (roughly 5"x5"x8") enclosure to make food easier to find, juveniles move up around a few months old, and adults need a minimum 12"x12"x18" vertical enclosure.
Mourning geckos generally do best at normal room temperature, roughly 75–82°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.
Low-level UVB (roughly 5–6% output) is increasingly recommended as good practice, though it isn't strictly mandatory for mourning geckos the way it is for a strongly basking desert species — their diet's built-in D3 from MRP covers much of the gap.
Mourning geckos need roughly 60–80% humidity, achieved through misting once or twice daily, with good ventilation to prevent the dampness from turning stagnant.
