Why Humidity Is Everything for Crested Geckos
Crested geckos need precise humidity to shed cleanly, stay hydrated, and thrive. Get it wrong and problems stack fast - here's exactly how to nail it.

Why Humidity Is Everything for Crested Geckos
Crested geckos (Correlophus ciliatus) are native to the tropical forests of New Caledonia, where humidity regularly exceeds 70%. Replicating this in captivity is one of the most important aspects of their husbandry - see our full Crested Gecko care guide for the rest of their housing and diet needs.
The Target Range: 60-80%
Aim for 60-80% relative humidity throughout the enclosure. A brief drop to 50% during the day is acceptable. In fact, a "wet-dry cycle" (misting heavily at night, letting it dry during the day) mimics natural conditions and prevents respiratory issues.
How to Achieve Proper Humidity
- Mist the enclosure once or twice daily, focusing on the walls and plants rather than directly on the gecko.
- Live or high-quality fake plants hold moisture and raise ambient humidity.
- Coconut fiber or a bio-active substrate retains moisture far better than paper towels.
- Screen tops release humidity quickly. If your enclosure struggles, cover 50-70% of the top with glass or acrylic.
Monitoring Humidity
A digital hygrometer is non-negotiable. Analog gauges are notoriously inaccurate. Place the probe mid-enclosure, away from the misting point.
Signs of Low Humidity
- Retained shed (especially on toes - can lead to constriction and loss of digits) - see our complete guide to reptile shedding for how to handle it safely
- Wrinkled or sunken skin
- Reduced activity and appetite
Keep it moist, keep it right. Your crested gecko will thank you with years of flappy-footed company. For natural history, see the Crested Gecko encyclopedia profile, or browse the rest of our Geckos care guide category.
