How To Lower Humidity In Bearded Dragon Tank

Do you own a bearded dragon and live in humid areas?

Are you worried about the problems which arise too high humidity in your reptile’s tank?

Keeping an enclosure set up correctly is one of the most important things to help your bearded dragon live a long and healthy life.

And quite often, the most forgotten part of this is the low humidity.

Bearded dragons come from the Australian desert, so you may need to know how to lower humidity in a bearded dragon tank.

After checking for the magic relative humidity of 30% – 40%, you may need to lower your bearded dragon’s tank humidity. This is done in many ways either by using a dehumidifier in the room, running the AC, opening a window, removing the water bowl, using a mesh top, or increasing the basking temperature.

Read on for details on how to take care of the humidity of the bearded dragon enclosure.

What Should The Humidity In A Bearded Dragon Tank?

As we mentioned before, the desert has low relative humidity, and the bearded dragon has evolved for this type of environment.

As such, the bearded dragon needs relative humidity to 30% – 40%.

 A good hygrometer, like this one on Amazon, will help you know precisely the humidity of your beardy’s tank.

You could also get one of the best thermometers for bearded dragons as most of these also have hygrometer function.

We recommend buying two and keeping one inside the tank and one on the outside.

Knowing exactly where the high humidity is coming from may change how you go about lowering the humidity.

Having too much moisture in the air can cause skin problems, stressed out bearded dragons (who then refuse to eat), or, worst of all, respiratory infections.

Having too low relative humidity isn’t usually a concern, but if you notice it is excessively low, add more water to the water dish, and this will raise the humidity.

You may also spray down the tank if it’s too low.

But this doesn’t usually happen. 


How Do I Lower The Humidity In My Bearded Dragon Cage?

There are several ways you may wish to go about lowering the humidity in your bearded dragon’s cage.

In this section, we’ll talk about these ways and things you may want to watch out for.

Dehumidifier

This is the most common way to lower the humidity of a room.

Many people (including myself) just keep one running in their basement to lower the humidity of a moist room.

There are a lot out there, so just pick one meant for a single room (we use the HomeLabs one here).

As far as fixes go, this one is all but guaranteed to settle your room to a specific relative humidity.

They’re often easy to use and programmable, so we can’t recommend these enough.

However, this is where having two hygrometers comes in handy.

If you notice the room is high AND the tank is high, a dehumidifier is a perfect fix.

But if you notice the room is fine, BUT the tank is high, there’s a fix needed inside the enclosure, and a dehumidifier won’t work.

Run The AC

Similar to the last idea, air conditioners naturally lower the humidity of a room.

This won’t work if your weather is cold, but it is an excellent way to lower the moisture in a pinch if you don’t have a dehumidifier on hand.

Running the AC is also one of the ways to help when the room is higher in its level, but if it’s just the tank, go for one lower on this list.

Open A Window

Often, rooms have higher humidity because of something cooking or water running with all the moisture trapped inside.

If you open a window, the air can balance itself out with the outdoor humidity.

This won’t work if it’s cold outside, and it won’t work if the outside is just as humid (or more) than the inside.

Warning!

If you do this, make sure the tank is secure and away from the window.

Beardies are good at escaping, and you don’t want them leaving the house without you!

Remove The Water Bowl

Having standing water inside the tank increases the humidity.

Remove the water bowl when not feeding or letting the bearded dragon drink to lower the interior moisture.

This fix works great when the humidity is high inside the tank.

It will work even if the room humidity isn’t.

However, the amount of this change is small.

Use A Mesh Top

If it’s just your tank with high humidity, the moisture in there often needs a place to escape.

For those with capability, you may want to switch to using a mesh top.

The mesh top will let the water dissipate better in the air and lower inside the tank.

Warning!

Make sure the mesh top is secured to the top of the tank.

Bearded dragons are semi-arboreal and love to climb and escape if they can. 

Increase Basking Temperature

Another hack to lower the humidity of the tank is to increase the heat from a basking lamp.

Turning up the heat will burn off some moisture.

This doesn’t work as well without a mesh top to let the moisture escape, though.

So make sure you get one of those hooked up first.

Even a temp increase of a couple of degrees will do quite a bit to help.

Basking temps should be around 105° degrees Fahrenheit (41° C) for adults, but can go up to 110° degrees Fahrenheit (43° C) (this is what babies need anyway).


Conclusion

We hope you enjoyed learning how to lower the humidity in a bearded dragon tank.

Making sure to keep the humidity down to 30% – 40% will avoid health problems such as infection and skin disease.

The reptiles aren’t meant for moist air, so use our tricks to keep them happy and healthy for a long time!
