Substrates For Bearded Dragons

It can be difficult to choose substrates for Bearded Dragons. There are so many different opinions where-ever you search, particularly on forums and Facebook groups. In this post we’ll go over a variety of different types of substrates for bearded dragons and help you decide which one (or ones) you want to use in your beardie’s tank.

What is a Substrate?

If you’re new to the world of reptiles you may have heard the term substrate mentioned but aren’t really sure what it is. Well basically the term substrate is used to describe an underlying substance and in this case its  the material used to cover the floor of a vivarium or terrarium.  You may also hear substrate referred to as bedding. The types of substrates available are divided into two categories; loose or particle substrate and solid or non-particle substrate.  Each has an array of options to choose from.

Which Substrate Should I Use for My Bearded Dragon?

This has to be one of the most commonly asked questions among bearded dragon owners. It has also been a long debated topic regarding which is best ….. particle or non-particle?. There are numerous forums where enthusiasts share their knowledge and experiences. This makes forums a great place to get some helpful information especially when starting out or if you’re unsure what type of substrate to use.  In my opinion there is no one substrate fits all, and no right or wrong category. There are many beardie keepers who will condemn the use of a particle substrate.  However there are many bearded dragons that thrive without incident on a particle substrate….. after all their natural habitat largely comprises of sand!

Careful consideration is needed when deciding due to the myriad of options on the market for both particle and non-particle.  Some are good but many should be avoided in both groups. Research is key to find the best best substrate option for you and your beardie.

Substrate Pros and Cons

With everything in life there are pros and cons the same is true when it come to substrates for bearded dragons. Here are a few things to consider when deciding on a substrate for you bearded dragon

    • The Age of the Bearded Dragon

      Adult beardies are fairly robust hardy creatures and cope well with various substrate options.  Babies and juvenile bearded dragons on the other hand  do not always cope as well.  Particle substrates should be avoided for bearded dragons under a year old. Mainly because they are still growing and will ingest loose particles often while feeding (and the babies are clumsy feeders).  Which will consequently increase the risk of a blockage of the intestine leading to impaction.  This can be life threatening.  Babies also poop a lot, using paper towels or something similar makes cleaning easier and quicker just remove the soiled paper and replace.

    • Particle Substrate?

      A particle substrate used for bearded dragon should be a soft and fine in texture with minimal dust residue and nontoxic. The smaller and finer the particles the easier it will be for the bearded dragon to pass any of the substrate it may have accidentally ingested.

      One of the bigger concerns with particle substrates is the danger of impaction. This is where Beardie ingests something that it cannot digest and then cannot pass in its faeces. We go into more detail in the post about My Bearded Dragon Looks Sick – What Could It Be?

    • Non-Particle Substrate

      A good option for the baby beardies, especially paper options.  On the down side the non-particle substrate does not allow the bearded dragon to dig or burrow which they would naturally do in the wild.

  • Is your Bearded Dragon Gravid (carrying eggs)?

    A gravid female will be looking to lay her eggs and to do so she needs to make a nest.  If your not using a particle substrate it would be a good idea to introduce a nesting tray of suitable moist / damp sand or soil (see below) to give her somewhere to dig.  This should be introduced as soon as notice her scratching around her enclosure shes preparing to lay. If you are already using a loose substrate it will be more obvious she is looking to nest. It is  still advisable to provide her with a designated nesting area.

    Play sand or reptile soil works well.  Vermiculite is also a good option. It expands with water retaining moisture for longer. Mixing some in with your choice soil of sand will more structure to the nest site. Providing your gravid female with a suitable nesting area will encourage her to lay and reduce the risk of her becoming egg bound.

Types of Particle Substrate

Sand

There are many varieties of sand products on the market.  It is however important to note that not all sand is the same. Builders sand, beach sand and anything similar should never be used as a substrate for your bearded dragon. These have sharp stones and other inclusions, its untreated and likely to contain harmful toxins and other nasties including parasites.

Bear in mind when considering sand that it can be more awkward to clean and can potentially harbour bacteria, fungal organisms and parasites. This isn’t a problem if you’re willing to meticulously clean the sand and even do full changes now and then to help reduce this. Fungal and bacterial infections will be minimised by keeping the humidity and temperatures correct.

    • Reptile Sand / Reptisand

      Made from fine particles of quartz sometimes referred to as silica sand, this product is non clumpy. It is available in various colours which can make the habitat stand out. There are however many reviews that state that skin staining is common problem and high levels of dust residue is also an issue.

      Due to being made from quartz crystals, the product is quite harsh and some people report that it can cause problems with irritating Beardies bowels and even potentially causing internal bleeding.

      Reptisand is probably best avoided for Beardies.

    • Calcium sand / Calci Sand

      Calci sand is not actually sand at all. It is in fact calcium carbonate, found in chalk and limestone. Calcium carbonate is an active ingredient used to treat heartburn found in many antacid products.  Some people have the view that if an inadvertent ingestion occurs its better to ingest calcium. The problem with this theory is that if ingested it can neutralise stomach acid. Which means that food digestion will be harder for your bearded dragon.

      It is also worth mentioning that if your bearded dragon thinks it is lacking in calcium there is a high chance they will actively eat the substrate. Consequently this will increase the neutralisation of the bearded dragon’s stomach acid.

      Calci sand is therefore best avoided for Bearded Dragons.

    • Vita Sand

      Vita Sand is the same as calci sand but fortified with vitamins and beta-carotene. Both calci sand and vita sand are extra fine to minimise the risk of impaction.  Both products are advertised as non dusty although many reviews report that dust is an issue as is the sand staining the skin of their bearded dragons.

      Vita sand therefore carries all the same warnings and issues as Calcisand and is best avoided for Bearded Dragons, despite the fact that the packaging shows a Bearded Dragon prominently on the front!

  • Play sand

    If you like the idea of using sand as your preferred substrate, play sand is a good alternative to the aforementioned options. Play sand is extra fine in texture, its is non toxic and should be silica free (check the packaging to be sure). It extremely cheap and readily available to the other sand alternatives. Play sand does not stain and is virtually dust free. Play sand is probably the closest you will get to replicating the bearded dragons natural habitat (apart from the colour).

    If you want to use sand as your substrate this is probably the best choice of all the options listed above.

Wood chips /  Sani chips

A wood based substrate of heat treated small chippings they are lightweight, long lasting and hygienic. Choosing wood chips as a substrate could been seen as controversial. The chippings are relatively large compared to other particle substrates, which could increase the risk of impaction.  Many would say that wood chips should be avoided as a substrate for bearded dragons, and are better suited for snakes and such like. However that said it is a popular choice frequently used by pet/reptile stores for adult bearded dragons.

Walnut shells

Made from crushed walnut shells this substrate is extremely coarse. The particles are fairly large and sharp in texture. Its also fairly expensive. Walnut shells should be avoided as a substrate for bearded dragons.

There have been reports on various forums and social media of Bearded Dragons requiring significant intestinal operations or even being put down because of being kept on walnut shells. The sharp edges can literally rip their intestines apart if ingested.

Reptile Soil

Made from a mix of peat moss, sand, soil and carbon. This substrate is good for egg laying and burrowing due to ability to retain moisture.  It is more suited for a tropical set up,  however that said it is becoming more popular to have an Eco ( bioactive ) environment. Although this is not an area I am familiar with, this soil is a great medium for plants to flourish in. If an Eco/bioactive set up is something that interests you there are some informative videos on YouTube. Search for “bioactive bearded dragon setup” or click here to check them out.

Coconut fiber

Also known as Eco earth, these are available as loose bags or dehydrated blocks. It is Eco friendly made from coconut husks and can be composted after use.  This works well as a tropical substrate due to its ability to retain moisture and increase humidity. Not the best option for a dessert reptile. It can be used dry but then makes it quite dusty and flaky.  Making it an irritant for your beardies eyes and respiratory tract.

Desert snow

Made from pulp derived from pristine hardwood. By separating the cellulose fibres from hardwood chippings produces a soft textured substrate. Hardwood pulp is also used to make tissue and toilet paper.  Dessert snow is biodegradable, renewable, non toxic and virtually dust free.  It is also highly absorbent making this a versatile substrate as it can be used for nesting.  This is a popular alternative in the USA but not commonly used in the UK.

Desert Bedding

Formulated to replicate the arid soils of the Savannah and desserts.  This is a clay based substrate making it suitable for digging and burrowing. It isn’t cheap but It comes in 4 different colours and is available in 7 or 20 litre bags.

Zoo-Med Excavator clay is a similar product and can be used to create tunnels, hidey holes and caves. Zoo-Med have a couple of YouTube videos demonstrating how to do this.

Types of Non Particle Substrates

Reptile Carpet

Reptile carpet is available in a range of sizes and several colours. It is soft and easy to cut to size. They are reusable and relatively easy to clean. It is advisable that you have several carpets or cut the carpet into sections to make cleaning easier. The carpet will need to be taken out, cleaned and sanitized regularly at the very least weekly. It may need to be as often as daily especially for the babies as they tend to poop a lot!  Buying multiple carpets can also become costly, but once bought they do last a while.

Sand Mats

Similar to the reptile carpet but these have a sandy texture designed to look like sand but without the loose particles. Sand mats do look effective in a beardies tank and come in a range of sizes. They are fairly expensive and multiples will be needed to replace while cleaning and sanitizing soiled mats. The same principles apply for sand mats with regards to the cleaning as they do with the reptile carpet.  Sand mats also look good as a wall covering.

Artificial Grass

It has been suggested that artificial grass is a good option, however there are many different variants around. Personally I would avoid using this due to the matting and looped fibres. There is a high risk that toes/nails could get caught especially for baby bearded dragons. This is also a costly option.  Reptile carpet and sand mats are a much better option.

Tiles

Tiles are popular for bearded dragon substrate, they are relatively cheap and easy to clean. The choices are endless. It is important to choose suitable tiles.  For example your shiny bathroom tiles will not be much fun for your beardie because he will not be able to grip and will slip and slide. This is easily rectified by turning the tiles over and have the raw side facing up. Slate tiles are great option they are textured and retain heat. If you like the idea of using tiles you can grout them in place, but check that its nontoxic and safe for pets.

Paper

Paper is often the go to for baby bearded dragons due to its simplicity.  Its easily replaced and hygienic.

  • Newspaper

    Easily available and easily disposable. Newspaper is suitable as a temporary flooring however the type of paper does vary. Some newspapers are printed on shiny paper these are not as absorbent. Print transfer is often a problem when using newspaper especially when its wet.

  • Kitchen paper

    Kitchen paper is probably the best option when it comes to using paper. It is extremely absorbent, and can be replaced with ease.  Babies and sick beardies (with loose poop) do well with kitchen paper because of the ease it can be changed out to help keeping their hygienic and clean.

  • Wallpaper

    Wallpaper makes an interesting alternative if you want to jazz up the look of the flooring. Its a really cheap option because you can get off cut pieces from the DIY stores for free. However the down side to wallpaper is that it is not as absorbent as newspaper or kitchen paper.

    Wallpaper doesn’t just have to be used as a floor covering.  Using it as it intended purpose and covering the walls can really individualize  beardies home!

    In conclusion

    As you can see there is much to choose from and there is good, not so good and things to avoid for both options. If you’re already using a substrate that works for you and you bearded dragon (whether is be particle or non-particle) and they are happy and healthy.  Stick with it.  If you are undecided or looking to try something new maybe consider having both types of substrate in your vivarium. For example half sand an half sand mat looks really effective. This allows the best of both substrates and allows you to see which your beardie prefers.

    Remember do your research and have fun with you beardie. 😊
