Best Leopard Gecko Substrate Buying Guide

Things to Consider When Buying a Leopard Gecko Substrate

The two biggest factors when it comes to leopard gecko substrate and leopard gecko bedding are the age of your new pet and the material of the gecko bedding. The age of your leopard gecko matters mostly due to their size and abilities. Younger geckos are more likely to accidentally ingest sand, for example, which can cause severe health problems such as impaction. Meanwhile, older leopard geckos may be more acclimated to sand and enjoy burrowing in a substrate that more closely reflects their home.

However, the biggest factor is the material. There are plenty of options out there and it can be easy to become overwhelmed. That said, we generally recommend starting from a few, known gecko substrates that are proven to work well – coconut fibers, terrarium moss, cavern substrate and carpets/lining.

Coconut fibers are ideal for new starters and young geckos, as they are soft and absorbent enough to ensure easy humidity and temperature regulation. They’re also ideal for adding plants, as this substrate can be quickly and easily moved – which is also perfect for geckos that are keen on burrowing.

Terrarium moss and carpets/lining work very well together, in that they generally shouldn’t be used as a stand-alone gecko bedding but add great durability and longevity to other substrates. Linings are quick and easy to apply, while moss do well to mimic the natural habitat of the leopard gecko.

Cavern substrate is a favorite of ours, when it comes to creating the best leopard gecko substrate. This is because you have the freedom to create your own tunnels – giving your leopard gecko a place to hide from the moment they set foot in their terrarium – or you can give your gecko complete freedom to burrow their own tunnels. They also hold humidity very well and give plenty of hiding space from heat lamps, when required.

Substrates to Always Avoid

Wood chips and wood shavings are among the top contenders of substrates to avoid for your leopard gecko bedding. These are prone to creating splinters that can get caught in the eye or nose of reptiles, making them a big no-no when it comes to the health and safety of your gecko. For similar reasons, substrates based on walnut shells, corn cob and gravel are best avoided, too.

Sand can be a hit-and-miss option. While it most closely resemble their natural habitat, it also increases the risk of impaction and digestive problems in your leopard gecko. This is because it is the most likely gecko substrate to be accidentally ingested. Our advice here is to only opt for sand once your leopard gecko is fully grown (young geckos are more likely to suffer from impaction) and when you are fully confident in your abilities to set up a suitable terrarium.

How to Set Up an Ideal Leopard Gecko Habitat

Getting the right leopard gecko tank setup can be tricky – especially if you’re new to reptiles as a whole. The key is to do a good level of research into every part of the leopard gecko habitat, so you can say with complete confidence that your terrarium is built with them in mind.

Before you start, you’ll need a tank for your terrarium. Your gecko tank will likely need to be between 10 and 20 gallons in size, giving them enough space to explore but small enough that they aren’t completely overwhelmed – or simply to stop them getting lost and causing you to panic and pull everything out to see where they are.

To start, you’ll need to ensure that your enclosure is suitably heated. Leopard geckos hail from warm climates that have average humidity. So, to meet these needs you’ll require a heat lamp that maintains a temperature of between 65 and 85F, but does not lower the humidity level to below 25% or raise it to 45%. This is absolutely essential and where you’ll likely spend the majority of your budget.

Because of the heat, you’ll also need to add some plants to your enclosure, which will give your gecko a good place to relax and sleep, as well as helping to create a good hiding place. Don’t forget that your heat lamp will need to be turned off in order to give your leopard gecko ample resting time – automatic timers are ideal for this, especially if you’re prone to forgetting.

Rocks are hit and miss, as they provide a great place for sunning themselves but may also overheat and therefore cause burns to your gecko. Instead, we recommend using logs or similar as a place to sun themselves.

Finally, you need to pick your substrate. This will have the biggest effect on the happiness of your new pet and a good quality gecko bedding can make owning your new pet much easier in the long run. Consider the above when choosing your gecko substrate, and do feel free to ask for recommendations from experience gecko owners, too.
