For leopard geckos, who live in warm, desert-like regions, you’ll want to look for substrates such as sand and clay, or a mix of both, along with dirt. It is important to note that any substrate—even bioactive ones—requires regular maintenance. According to Dr. Cleary, "many owners think they are making a mini-ecosystem where they never have to clean out feces and urine, but it just leaves room for dangerous levels of ammonia to build up." Our favorite substrate for leopard geckos is The Bio Dude Terra Sahara Bioactive Reptile Substrate. This mix consists of a blend of climate-appropriate soils. It can support desert plants and helps keep humidity low.

It’s aerated enough for proper drainage but has enough structure so that your gecko can make tunnels and burrows. Terra Sahara reptile substrate is also bioactive, meaning it has microorganisms commonly found in soil, and can support desert plant life. This makes it an especially good pick for planted terrariums. However, don’t go with a bioactive substrate expecting it to be low maintenance, even if they’re often described that way. You’ll still have to clean your terrarium of waste regularly. Also, it carries an impaction risk. Excellent at maintaining a healthy humidity level in leopard gecko environments, Bio Dude Terra Sahara Bioactive Reptile Substrate is available in 36-quart and 6-quart packages. Materials: Natural sand, clay, soil | Quantities: 6-, 36-quart bags Best Sand Exo Terra Desert Sand Credit: Amazon $16 $15 at Amazon View on Exo-terra.com What We Like Natural Sifted for ideal grain size Excellent heat conductor What We Don't Like Allows for digging but not tunneling Some impaction risk Exo Terra Desert Sand is another great natural option for your substrate. This sand is safe for reptiles and matches the types of environments leopard geckos live in in the wild. This is non-calcium sand, so it is safe for reptiles and snakes, though there is still some impaction risk. It has also been sifted to remove large grains and rocks that can be harmful to your pet. The Exo Terra Desert Sand is a great heat conductor, so it is fitting for desert-dwelling reptiles.

It supports burrowing and can also be molded to hold its shape. This allows you to create structures like mounds, terraces, and other features that can make your enclosure more natural and interesting for your pet. It’s often combined with sand or another substrate and does carry an impaction risk.

The benefit of a liner is that it is one piece, which means there is no chance of your pet ingesting anything harmful from the substrate. It also means that it’s easy to install and lightweight. You can order the size closest to that of your enclosure and cut it down. These tend to be more affordable than most loose substrate options; however, it should be noted that they do need to be replaced as they soak up substances and undergo regular wear and tear. Also, unlike many of our other options, they allow for neither burrowing nor tunneling. Materials: Woven fiber | Quantities: 11.75 x 23.5 inches; 9.75 x 19.75 inches; 11.75 x 29.5 inches; 11.75 x 47.5, inches; 17.5 x 47.25 inches; 17.25 x 71 inches Best Hideout Zilla Reptile Bark Terrarium Decor Credit: Amazon $20 $12 at Amazon $22 at Chewy What We Like Non-porous material Resistant to bacterial growth Easy to clean and maintain What We Don't Like Sharp edges need to be filed down While a terrarium liner or carpet eliminates impaction risk, one major downside is that it doesn't allow your leopard gecko the ability to burrow and hide, which is their instinct. Adding a hideout like this one from Zilla offers a solution to this dilemma. It's made of a safe, non-porous synthetic material that's resistant to bacterial growth, which makes it easy to clean and maintain. Crafted to replicate the look of natural wood bark, it provides ample space for geckos to find privacy and overhead shelter. However, choose the appropriate dimensions to match your pet's lifestage and size to ensure they don't get caught in too narrow an opening. Also, some pet parents have encountered some sharp edges, which can easily be filed down. Materials: Plastic | Quantities: 2.25 x 5.25 x 2 (small); 3 x 8.3 x 3.6 (medium); 5 x 10.75 x 5.5 inches (large) Final Verdict The Bio Dude Terra Sahara Bioactive Reptile Substrate is bioactive, with all-natural ingredients, and it's our overall favorite leopard gecko substrate. If you plan on making your own mix, then Zoo Med Excavator Clay and Exo Terra Desert Sand make great mixing options on their own or in combination. What to Look For in a Substrate for Leopard Geckos A Natural Habitat A substrate similar to a leopard gecko's natural environment is a key component to your gecko's well-being, especially in combination with adequate light, heat, and hydration. The desert home of the leopard gecko suggests a substrate that drains quickly, but burrowing behavior also means you'll want a substrate that retains its structure—in other words, it shouldn't be too loose. A combination of sand, soil, and clay will ensure a substrate that stays aerated, doesn't mold, and remains loose enough for your gecko to dig around in it, while firm enough that the substrate isn't immediately collapsing back into holes your gecko has dug (this makes all-sand substrates not ideal). Dr. Cleary also recommends against scented or especially odorous substrate, as it can "mask the scent of food, which can make feeding harder. These substrates can sometimes also make treating pests a lot harder." Maintenance Even with a bioactive substrate, efficiently removing your gecko's waste is the best way to ensure a clean and sanitary environment. Solid waste should be removed daily, while portions of substrate that are wet with urine can also be scooped out and disposed of. You'll want to have substrate on hand to replenish the volume you remove during cleaning. Finally, the substrate should be fully replaced at least once every four months. FAQ Can I use paper towels as a leopard gecko substrate? Paper towels are not an ideal leopard gecko substrate because they deny your pet opportunities to follow their instinctual needs to burrow. Though they are easy to clean, paper towels hold moisture that can raise humidity too much for desert-dwelling reptiles. Though ripped-up newspaper is also not ideal, it is a better option in a pinch than paper towels. Does loose substrate cause impaction? Loose substrate carries a risk of impaction if your gecko ingests too much of the substrate. This risk can be mitigated by ensuring that any loose substrate does not contain large pieces. Also, when introducing any new substrate, monitor your pet during feeding for a few days to observe their behavior and assess the risk of impaction.Another way to mitigate the risk is to ensure your gecko is properly hydrated—this will aid in their digestion and help them pass any small pieces they do end up ingesting. Do leopard geckos have a preferred texture for their substrate? One of the best ways to care for leopard geckos is to use substrate materials that provide a safe environment for them to hide and move about in without the risk of ingestion. Paper and indoor/outdoor or reptile carpets are good options because they present a low ingestion risk, unlike sand, which can be dangerous for young geckos. You should also avoid wood shavings, which can cut their tiny feet and contain volatile oils that can irritate their skin. Do leopard geckos need a heat lamp? While leopard geckos may not necessarily need UVB lights, they should always have heat lights or some type of white light on a 12-hour cycle to provide an ambient temperature range between 78 and 90 degrees during the day. You can use a regular incandescent or fluorescent bulb to mimic the natural day/night cycle for your gecko's behavior patterns.A red heat bulb, purple heat bulb, or ceramic heat emitter can also provide supplemental heat to prevent the enclosure temperature from dropping below 70 degrees at night.
