What is Humidity?
Before we dive into the ins and outs of lowering the humidity in your Leopard geckoās tank, letās first define what humidity is and why itās vital to a Leopard geckoās health.
Humidity is the presence of water vapor in the air.
The higher the humidity level, the more water vapor is present in the atmosphere.
Heat causes water to evaporate and rise as a vapor into the air, meaning hot climates tend to have higher humidity levels than colder climates.
Why Humidity Levels are Important for Leopard Gecko Health
Leopard geckos are native to dry and semi-desert areas in Afghanistan, Iran, Iraq, and northwest India.
If their captive environment does not closely mimic their natural habitat (temperature, humidity levels, etc.), their health and quality of life will suffer.
For example, if your Leopard geckoās tank humidity levels are regularly too high, it could develop serious respiratory issues, pneumonia, and skin-related infections.
High humidity levels also promote unhealthy fungal and bacterial growth in tanks, leading to other health issues.
On the other hand, if your Leopard geckoās humidity levels are too low, it can suffer a whole host of health issues, including problems shedding, dehydration, and increased risk of infection.
What Is The Ideal Humidity for a Leopard Geckoās Tank
We now know why itās crucial to maintain the correct levels of humidity in your Leopard geckoās tank, but just what is the ideal humidity for your Leopard gecko, and how can you gauge and measure it?
The ideal humidity for a Leopard geckoās captive environment is somewhere between 30 to 40 percent humidity.
This should most likely match the normal humidity levels in your home.
However, if you live in a highly humid or arid region, your home may have lower or higher humidity levels, meaning you may need to work harder to maintain proper humidity in your Leoās tank.
The best way to keep tabs on your Leopard geckoās tank humidity levels is to invest in a high-quality hygrometer like this one.
- Day/Night Temperatures
- Humidity & Timing Control
- Alarm When Temps Reach Unsafe Levels
It measures humidity levels and tracks the tankās temperatures, so it will always know the temperature and humidity and adjust it as needed.
One important thing to note is that Leopard geckos require higher humidity levels (between 70 and 80 percent) to support their normal shedding process.
The #1 reason why Leopard geckos experience problems shedding is due to low humidity levels.
But since geckos shed anywhere from every week to once every other month (depending on their age and growth rate), this means they regularly need access to high levels of humidity.
However, we already know their ideal humidity is between 30 and 40 percent, and constant immersion in a high humidity environment is dangerous for a Leopard gecko.
So, whatās the solution to giving them adequate humidity to support good sheds (70 to 80 percent humidity) while ensuring their overall tank levels stay between 30 and 40 percent humidity?
The best way to balance this issue is to provide your Leopard gecko with a humid hide full of moist sphagnum moss.
- Long-Lasting: Long-Fiber and Leafy Green Sphagnum Moss
- High Absorbency: Controls Tropical & Wetland Humidity
- Sustainable: Ecologically Regulated Harvests
Youāll want to place the humid hide on the warm side of the tank and regularly measure its humidity to ensure the hide stays between 70 and 80 percent.
This ensures your gecko has access to high humidity whenever it needs it but keeps the rest of your tank in the healthy 30 to 40 percent range.
How to Tell If Leopard Gecko Tank is Too Humid
One of the best ways to monitor your Leopard geckoās tank humidity is to invest in a hygrometer, as we mentioned earlier.
However, if you donāt have one of these right now, there are other ways to determine if the humidity is too high in your geckoās tank.
One obvious sign of high humidity levels is a foggy or steamy tank.
If your tank appears steamy or foggy, it is likely too humid for your Leopard geckoās ideal environment.
Another sign of high humidity is condensation droplets running down the sides of the tank.
If you observe any of these signs, you most likely need to lower your geckoās tank humidity.
How to Lower Humidity in Leopard Gecko Tank
Suppose your Leopard geckoās tank hygrometer registers humidity levels of over 40 percent or sees visible signs of high humidity (like a steamy or foggy tank).
In that case, itās time to work on lowering your tankās humidity levels.
There are several easy and practical things to do to decrease tank humidity; letās look at six of them.
Increase Airflow
Start by increasing the tankās airflow.
If a tank doesnāt have enough airflow and circulation running through it, the heat and condensation can build up and spike humidity levels.
One of the best ways to ensure your Leopard geckoās tank has adequate airflow is to purchase a tank with a screen top.
If your tank didnāt come with a screen top, you might consider buying a screen cover like this one.
The extra airflow provided by a screen top helps keep the enclosure dry and humidity levels low.

Reduce Water Bowl Size
Another way to instantly decrease humidity in your Leopard geckoās enclosure is to reduce its water bowl size.
Since humidity is just evaporated water, having a large water bowl inside the tank means thereās more water around to vaporize and turn into moisture.
So try swapping out a large dish for something a little smaller.
If you go with a smaller water bowl, make sure to check in more often to make sure your gecko has enough water to drink.
Get a Dehumidifier
If your geckoās tank has consistently high humidity levels, you may want to use a dehumidifier to remedy the problem.
Dehumidifiers suck up extra humidity (water vapor) in the air, safely and effectively lowering humidity levels.
If you purchase a small, portable dehumidifier like this one from Amazon, you should be able to fit it directly inside your Leopard geckoās tank.
- EASY TO USE: This mini dehumidifier is spill and mess free. Just hang and go! Non-toxic, child and pet safe! Your small rooms will be dry and odor free. Works for areas up to 333 cubic feet

- SMALL, SLEEK DESIGN: This portable small design lets you hang or conveniently place the dehumidifier anywhere to fight pesky humidity! Cars, closets, boats, cabinets, gun safes, and even gym bags! A very convenient cool gift for everyone!
When using a dehumidifier, regularly check to make sure humidity levels donāt drop too far below 30 percent and always provide a humid hide so your Leopard gecko can retreat to a damp space if he needs to.
Turn Up the AC
Another easy way to decrease your Leopard geckoās tank humidity is to turn up the AC in your house.
Remember, more heat equals more water evaporation, which creates more moisture.
Turning up the AC should help regulate and lower the humidity levels in your geckoās tank.
Remove Plants
Live plants retain water and release it slowly into the environment, meaning they add to an enclosureās humidity levels.
Live plants are often used in reptile tanks to increase humidity and moisture.
However, if you have a low humidity reptile like a Leopard gecko, you may want to reduce the number of live plants in the tank.
Opt for faux plants and vines like this one or like this one.
That way, the tank stays dry, but your gecko still has plenty of branches and vines to climb on.
Replace Substrate
The final way to lower humidity in your Leopard geckoās tank is to replace traditional substrate with tiles or a low-moisture substrate option.
If you have been using soil or something like Cypress mulch, chances are your substrate is holding on to moisture and adding to the high humidity levels.
Try using a dry, reptile-safe liner such as this one, or if you still want a soft substrate, opt for heat-treated Aspen chips like this.
Conclusion
If your Leopard geckoās tank is too humid, we hope this article on lowering the humidity in a Leopard Geckoās tank gave you the information you need to remedy the problem.
Start by increasing ventilation and airflow.
Then, consider purchasing a dehumidifier, reducing the water bowl size, removing live plants, turning up the AC in your house, and replacing your substrate with a dry or tile-like flooring option.
Remember to closely monitor your Leopard geckoās humidity levels with a high-quality hygrometer and adjust the tankās humidity when needed to prevent future health problems and illnesses.
