Humidity Levels for a Bearded Dragon

Bearded dragons come from the dry, desert areas of the Australian outback. Because of this, bearded dragons require a low degree of relative humidity that is vital to their survival.

Humidity levels for a bearded dragon raised in captivity are extremely important. Relative humidity inside the enclosure should be kept between 35 to 40 percent. This level is identical to the humidity found in the wilderness of Australia.

Bearded Dragon HumidityAvoid using full glass or plastic covers on the enclosure. These covers will trap air and humidity within the terrarium and create stale, stagnate air. This can lead to higher humidity levels and even respiratory problems with a bearded dragon.

Good ventilation of the enclosure is the best way to reduce humidity. Use screen covers that are made of heavy-duty mesh wire or screen. This will provide adequate air flow and help supply fresh oxygen to your bearded dragon.

The improved air flow will also help dissipate humidity and noxious gases associated with your bearded dragon’s respiration and defecation within the terrarium.

Excessively large water dishes can also increase humidity levels as the water evaporates. Use the smallest water dish possible for your bearded dragon’s needs.

Placing the water dish away from the basking light can also help reduce evaporation and humidity.

Avoid using bark, or coconut fiber substrates as these can retain moisture and raise humidity levels.

If you live in an area that has high humidity levels, such as coastal or swampy areas, you may need to place a dehumidifier in the room that contains the terrarium.

It’s a good idea to place a humidity gauge within the terrarium to monitor humidity levels. This will eliminate any guessing as to what the levels are in your beardie’s terrarium.

The only exception to this is the Coastal Bearded Dragon. These lizards live in the coastal regions and do well in slightly higher humidity, although it should not exceed 55 percent.

    I just put my dragon in a 60 gallon tank and can’t seem to get the humidity down. I don’t have very much water and I have all the same stuff as before. Any low cost hints?

      I used a higher wattage day light source dried it up quickly, just allow more distance between light and beardys if it gets to hot

      We live on the east coast and found humidity control in our beardies tank to be an issue as well. We bought some plants that regulate humidity in the home like peace lily’s and reed ferns. This has helped reduce the humidity of the house there in reducing it in the cage as well. If the plants don’t help then the dehumidifier is the next step. Hope this helps. The plants are relatively cheep compared to hundreds of $ on a piece of equipment.

    hey katie :) to lower humidity in your bearded dragon’s terrarium, make sure his lamps are hot enough (90-100) and it’s really effective to have your ceiling fan or any fan on. The fan creates better airflow in the tank an will lower the humidity :) you can also try moving the water bowl to the “cool” side of the tank, or take it out until the humidity goes down. also make sure there isnt anything in your tank that might be holding moisture, such as moss or some types of wooden sticks, etc.

    the most important key is the fan to create air flow. (:
