How Do I Lower the Humidity in My Bearded Dragon’s Tank?

When it comes to caring for bearded dragons, you probably know you have to make sure that everything within the enclosure is at the right temperature. However, humidity can be just as important.

You want to keep your bearded dragon’s humidity around 35%-40%. To lower the humidity in your bearded dragon’s tank, you can use a mesh cover, remove the water bowl, change the basking bulb, open a window, use an AC, or buy a dehumidifier.

Keeping the humidity inside your bearded dragon’s tank at the right level is important to keep it healthy. Read on for more information on how to lower the humidity within your bearded dragon’s tank.

How Humidity Can Hurt Your Dragon

According to National Geographic, bearded dragons are lizards that thrive in hot and arid climates, such as deserts, subtropical woodlands, savannas, and scrublands. This means that the temperatures within your bearded dragon’s tank has to be warm and contain little humidity.

Pro Tip: The humidity within your bearded dragon’s tank should be around 35% to 40%.

Too much humidity can lead to your dragon developing respiratory infections. Too little humidity can create shedding problems for your bearded dragon. As such, you should use a hygrometer to measure the amount of humidity inside and outside the tank to help determine the right method to lower the humidity.

How to Lower the Humidity Within the Tank

Lowering the humidity of your bearded dragon’s cage is not hard to do once you figure out where the source of the humidity is coming from.

If the source is coming from within the tank, there are several methods you can use to lower the humidity. Let’s discuss them below.

Change the Tank Cover

The first thing you can do to lower the humidity within the tank is to change the cover you are using for your tank.

If the tank cover does not have any ventilation or is constructed with materials that attract moisture, it can contribute to the buildup of humidity in the tank.

Buying a mesh cover for your tank can solve this problem. You will want to make sure that the mesh lid you purchase securely fits over the tank so that your bearded dragon cannot escape.

Remove the Water Bowl

While bearded dragons need water, they don’t drink it very often. Most of the water they need comes from the food they eat. If you have a water bowl within your enclosure, this can be a significant source of humidity within the tank.

You can reduce the amount of humidity by moving the water bowl away from the basking lamp and to an area with less heat. If this does not work, try taking the bowl out of the tank whenever your bearded dragon is not using it.

Make sure that you take the size of the water bowl into consideration. Your bearded dragon needs a bowl that is large enough and shallow enough for it to get in and out of easily.

If the bowl is larger than the bearded dragon, consider placing a smaller bowl inside the tank. A smaller bowl can also help to reduce the humidity levels.

Change the Basking Bulb

Another way to lower the amount of humidity inside your bearded dragon’s tank is by changing the basking bulb that you use. Buying a basking bulb that is a bit hotter than your current bulb such as a 100-watt basking bulb or a 75-watt basking bulb can burn off the excess moisture within the tank.

However, you will want to make sure that the bulb you buy does not raise the temperature of the tank too much. The temperature of the tank should be 100°F (38°C) for an adult and about 110°F (43°C) for baby bearded dragons.

Change the Bedding and Decorations

The bedding and decorations in your tank can also contribute to a rise in humidity within the tank.

If your bearded dragon’s bedding is made from bark or coconut fiber, it may be attracting moisture and raising the humidity level in the tank. Try changing the bedding to sand or newspaper and see if this will improve the humidity conditions within the tank.

If you use live plants in your bearded dragon’s tank, try replacing them with artificial ones to cut back on the amount of humidity being introduced into the tank.

How to Lower the Humidity From Outside the Tank

If the humidity is coming from outside the tank, you can use a hygrometer to locate the source. Place hygrometers throughout different areas of the house and see which areas closest to the bearded dragon’s tank have high humidity readings.

Activities that generate heat, such as cooking, can contribute to the amount of humidity within the tank. To lower the amount of humidity generated within the area, try opening a window, turning on the AC, or buying a dehumidifier.

Open a Window

If your bearded dragon’s tank is near a window, use it to help control the humidity within your bearded dragon’s tank.

Open the windows or doors near your tank to help relieve the humidity in the area. If the humidity outside is lower than the humidity inside your dwelling, the moisture will escape out through the window instead of accumulating in your bearded dragon’s tank. However, if the humidity is higher outside, then this will not be an effective method to use.

Use an AC

Turning on an air conditioner can help keep temperatures in your tank low. While not ideal, you can use this method if you need time to gather some items discussed above. This method works if the source of humidity is coming from outside your bearded dragon’s tank because it can cool down the room, which will lower the humidity.

Note: Do not keep the AC on for too long; otherwise, you can significantly lower the temperature inside the tank.

Also, if the inside of your house is already cold, then an AC will not be a very effective method to use.

Buy a Dehumidifier

Purchasing a dehumidifier can help lower the amount of humidity in your tank. A dehumidifier is a device that removes excess moisture from the air. This is a good tool to use if the rooms near the tank are the sources of high humidity. Setting a dehumidifier near the tank will help reduce the overall humidity in its vicinity.

There are a variety of different dehumidifiers to choose from. You can get a large one that covers a lot of space like the Vremi Dehumidifier, or you can get a small dehumidifier such as the E-500 Renewable Mini Dehumidifier.

Conclusion

Bearded dragons need to have a certain amount of humidity within their environment in order to remain healthy. Too much humidity can lead to respiratory problems for your bearded dragon, and too little can affect its shedding process.

If you notice that the humidity within the cage is a little too high, try some of these methods:

  • If humidity is building up inside your tank, you can change the tank cover, change the basking bulb, or remove the water bowl. These methods should help decrease the amount of humidity within the tank.
  • If the humidity is originating from outside the tank, try opening a window, using an AC, or purchasing a dehumidifier. These methods will decrease the amount of humidity in the area.

Follow these steps to keep the humidity in check and keep your bearded dragon happy.
