What Is Substrate?

Substrate describes the type of bedding you use to line your snake’s enclosure. 

It makes up the ground your snake will be slithering around on. 

A good substrate is defined by a few things: the ability to retain moisture, absorb urine without leaving a foul odor, allow burrowing if needed, and avoid being eaten or inhaled. 

You’ll also want to take into account price and how easy it is to clean and replace. 

The best bedding for your snake will be based on their specific requirements, as different snakes have different needs.

Best Substrates for Snakes Based on Common Species

You may be wondering which type of substrate your specific species of snake requires. 

You need first to understand what environment they’re used to and whether or not they like to burrow. 

Snakes from more humid environments will need bedding known to retain moisture, while this may not be as important for a snake from a more arid climate. 

Your bedding options are cypress mulch, aspen shavings, coconut fiber, orchid bark, and artificial turf. 

If you’re hunting for cheaper alternatives, you may use newspaper, paper towels, or carpeting in certain circumstances. 

Below are some of the most common domesticated snake species and the bedding they prefer:

Corn Snakes

Corn snakes are native to the southeastern United States and thrive in places like overgrown fields and forests’ outskirts. 

Corn snakes enjoy burrowing, so you need to utilize suitable bedding. 

Most owners have a lot of success utilizing 1-2″ inches (5.1 cm) of aspen shavings or cypress mulch, both of which hold moisture well and control odor. 

Garter Snakes

The natural environment for garter snakes is usually humid. 

In the wild, you typically find garter snakes around lakes, rivers, and marshes. 

Like corn snakes, they also like to burrow. 

The ideal bedding for them would be aspen shavings, cypress mulch, or coconut husk bedding. 

Boa Constrictors

Boa constrictors don’t have as many requirements as some of the other snakes on this list. 

Unlike the snakes already mentioned, they do not burrow. 

While the substrates we listed before are all appropriate to use, boa constrictors are also happy with cheaper options like newspapers, paper towels, and carpeting. 

Though cheaper, these types of beddings will require more frequent changes to stay clean.

Ball Pythons

Ball pythons are also able to utilize some of the cheaper options, like newspapers and paper towels. 

However, if you’re able to afford it, the best options are cypress mulch or aspen shavings. 

Ball pythons don’t generally require much humidity. 

If you are utilizing bedding known to retain a lot of moisture, make sure you monitor the enclosure’s humidity level.


We find Kingsnakes in a variety of environments, such as woodlands, deserts, and marshes. 

They also love to burrow, making a couple of inches of cypress mulch or aspen shavings suitable options. 

The cheaper options will not work for kingsnakes.

Substrates to Avoid

There are a few overall qualities to avoid when selecting a substrate for your snake. 

Substrate should not have a bad smell, be treated with chemicals, or be easy for a snake to swallow. 

Below are a few examples of readily available substrates which are not suitable for snakes:


While sand appears comfortable and aesthetically pleasing bedding for snakes, you should avoid it. 

Especially if your snake likes to burrow, sand can easily get trapped in their nostrils or be ingested. 

This is extremely harmful to the nasal passages, lungs, and bowels. 

Ingested sand will cause issues with your snake’s digestion and result in an impaction.

Cedar or Pine

Some bedding options will contain cedar or pine. 

Both are harmful to snakes as they release oils which are dangerous to their skin and respiratory system. 

Snakes cannot escape these fumes when they are within an enclosure, so please pay attention to substrates to ensure they do not contain either of these ingredients.

Cat Litter

Even though cat litter works great to pick up the urine and excrements of our feline friends, we don’t recommend it as a substrate for snakes. 

Cat litter is easily ingested and can cause digestion issues and impaction, similar to sand. 

The grainy texture can cause your snake to develop abrasions or bruises. 

Lastly, the dust can irritate their nasal passages and lungs, making it more difficult for your snake to breathe.

Commonly Asked Questions

Can substrates be mixed? – Yes! Most substrates are safe to mix. 

For example, if you notice the humidity in your tank is getting too high with your current substrate, you are allowed to mix in a drier substrate to balance everything out.

How often should I change bedding? – This will depend on the activity level of your snake; as a general rule, you should spot clean the bedding on a daily or weekly basis and do a deep clean with substrate replacement every month. 

Sometimes you may go longer if the bedding still appears clean, and there are no foul odors.

How do I deep clean the tank? – First, remove your snake and place it somewhere safe. 

Clean all bowls and accessories. 

Remove all old substrate and scrub the enclosure clean with hot soapy water and rinse well before replacing it with a new substrate.
