Cypress mulch is one of the best substrates or beddings that you can use for the most type of reptiles, including blue tongue skinks. The Zoo Med cypress mulch can be used by itself, or you can also mix it with other kinds of substrates, such as coco husk, sphagnum moss, or coco fiber.

The advantage of this kind of substrate is that it retains moisture and humidity well, soft enough to burrow, can be used with a mist, and inexpensive. However, it quickly molds when your pet drops some food in it, so you’ll have to always clean your pet’s terrarium.

2. Zoo Med Sphagnum Moss

This type of moss can be found in places in mild, temperate climates, such as North America, New Zealand, and Ireland. With the help of sunlight, this type of moss grows plenty on topsoils. So why use a sphagnum moss for your skink?

There are quite a few things why it is one of the best bedding of reptiles, especially for your blue tongue skink. It is highly mold resistant, it retains great humidity, and it looks very native on your pet’s enclosure, which would make your pet more comfortable in its own terrarium.

3. Reptile Prime Coconut Fiber Substrate

Coconut fiber beddings is another great choice for blue tongue skinks, especially for the Indonesian species, it also works pretty well when mixed-in with cypress mulch or topsoil.

You can use this product as it is or mix it with sphagnum moss, cypress mulch, or topsoil to increase its humidity retention. It also has a nice look in terrariums, which is in a contrast to something like the coco fiber or sphagnum moss substrate. However, some fir bark bedding products use pine trees instead of fir trees, so make sure to check the bedding’s label before making a purchase. Pine trees are not good for your lizard’s overall health.

5. Kaytee Aspen Substrate

For the Northern and Eastern species of blue tongue skinks, using an aspen wood shaving is one of the most popular types of bedding for them. Aspen is a type of tree that usually grows on areas with colder climates, it is firm, but soft enough to burrow, and doesn’t contain any kinds of aroma which is great for your pet’s health.

Here are other reasons why it is great for skinks, it is light and soft where your pet can easily hide and burrow to, it can be safely ingested in small amounts by your skink without causing health conditions, it does a great job in retaining humidity, and looks very nice in the enclosure.

6. T-Rex Sani-Chips Substrate

Basically, this type of chip bedding is quite similar to aspen wood beddings. However, Sani-chips are much smaller than the usual aspen shavings. As the regular aspen bedding, sani-chips also work pretty well in absorbing moisture and keeping a stable humidity level.

Also, since they are much smaller compared to the regular aspen shavings, they won’t get lodged or stuck anywhere in your lizard’s nose, mouth, or eyelids. They are also very pliable and soft enough for your pet to easily move around and burrow into it. The only downside of this substrate is that it molds easily when wet, so you’ll have to change it out once it got too wet from absorbing moisture.

7. Exo Terra Coco Husk Substrate

Therefore, if you want a much finer particle substrate then choose the fiber, if not then you can consider getting this product.

As for their benefits, both types of substrates works pretty well in retaining humidity, absorbing moisture, eliminating odor, and provides a naturalistic environment inside the terrarium. Also, it may be a bit bulkier than the fiber one, but it is still soft enough to be burrowed by your bluey.

8. Zilla Bark Blend

Here is another bark substrate that you can choose from. Aside from Exo Terra and Zoo Med brands, Zilla also provides a good quality of fir bark substrate for all kinds of reptiles.

This substrate is made from 100% organic bark without being mixed with dyes. Also, this is heat treated to absorb moisture efficiently which conveniently helps in maintaining the terrarium’s humidity level. It is also eliminated from unwanted pests, so expect this product to be free from critters.

9. Zilla Aspen Substrate

Here is another option for aspen wood shaving beddings. This product is prepared in aspen chips and not finely ground. However, its chip sized aspen particles are not too big to prevent your pet skink from burrowing into it. And since the substrate is heat treated, expect it to have an ultra absorbent feature.

Aside from that, it’s also excellent in maintaining the terrarium’s humidity levels. It is also hypo-allergenic, meaning it doesn’t contain any kinds of harmful chemicals that can affect your lizard’s health.

10. Zoo Med Loose Coconut Fiber Substrate

Alfalfa Pellets

Walnut Litter and Corn Cobs

These are indigestible and can cause an impaction to your lizard when ingested accidentally.

Calcium Sand

Clay Litter

Cat Litter

Some reptile owners out there use cat litter as their reptile’s alternate sand substrate. It may good for some reptiles but not for the skinks. It can also be dehydrating, toxic, dusty, and can cause impaction risks.
