Gecko humidity requirements in a vivarium vary with the species' natural environment, from desert to tropical rainforest. Putting in a hygrometer will enable you to maintain the humidity in your vivarium at the correct level. If extra humidity is needed, this is easily supplied.

Skill level:


  1. 1

    Add a shallow pool with a wide surface area. Evaporation adds humidity.

  2. 2

    Plant tropical foliage in a rainforest vivarium.

  3. 3

    Use a spray bottle to spritz the interior of your vivarium twice a day. Be sure to let it dry completely before re-wetting to discourage mould and bacterial growth. Your gecko may enjoy being misted and may even drink the drops from its body.

  4. 4

    Install a water-holding substrate such as vermiculite or an absorbent ground cover, such as sphagnum moss or orchid bark, for slow evaporation.

Tips and warnings

  • Do not try to increase humidity in your vivarium by limiting the ventilation -- your gecko will suffer from this and may get sick.
