Humidity Levels for a Bearded Dragon

Share

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.
