How do I maintain the right humidity in my leopard gecko's enclosure?
Maintain a humidity range of 60–80% in your leopard gecko's enclosure to ensure their health and well-being.
Target Humidity and Temperature
Your leopard gecko's enclosure should have a humidity range of 60–80%. The warm side should be 88–92°F (31–33°C), while the cool side should be 75–80°F (24–27°C).
These numbers are crucial for your gecko's health and behavior. The warm side provides the belly heat they need, while the cool side allows them to self-regulate their body temperature.
Leopard geckos are crepuscular/nocturnal, so they will be most active during the evening and night when the warm side temperature is reached.
- Warm side: 88–92°F (31–33°C)
- Cool side: 75–80°F (24–27°C)
- Humidity range: 60–80%
Creating the Gradient
The gradient of temperature and humidity is essential for your gecko's ability to self-regulate. They will move between the warm and cool sides to maintain their preferred body temperature.
This natural behavior helps them regulate their metabolism and overall health. The humidity gradient also supports their shedding process.
- Self-regulation through movement between warm and cool sides
- Supports metabolism and overall health
- Facilitates shedding process
Controlling Variables
Use a heat source like a heat mat or under-tank heater on a thermostat to maintain the warm side temperature. Ensure the cool side is away from the heat source.
To control humidity, use a water dish and a moistened substrate like coconut fiber or orchid bark. Ventilation is key to prevent mold growth.
Measure temperature and humidity at the animal's level to ensure accuracy. Use a digital thermometer and hygrometer.
- Use a thermostat-controlled heat source
- Maintain a moistened substrate
- Ensure proper ventilation
- Measure temperature and humidity at the animal's level
Observable Signs
If the humidity is too low, your gecko may become dehydrated, have difficulty shedding, or exhibit signs of stress. Conversely, if the humidity is too high, they may develop respiratory issues or skin infections.
Look for signs like excessive basking, lack of appetite, or changes in shedding patterns. These can indicate that the environment needs adjustment.
- Dehydration or difficulty shedding at low humidity
- Respiratory issues or skin infections at high humidity
- Excessive basking or lack of appetite as signs of incorrect temperature

Related questions
How often should I check the humidity in my gecko's enclosure?
Check the humidity at least twice a day, especially during shedding periods, which can last up to 2 weeks.
What should I do if my gecko's shedding is not going well?
Increase humidity to 80–90% and ensure the gecko has access to a humid hide. If shedding is still an issue, consult a veterinarian.
Can I use a humidifier in my gecko's enclosure?
No, a humidifier can create too much humidity and lead to mold growth. Use a water dish and a moistened substrate instead.
