Crested geckos have become increasingly popular as pets due to their unique appearance, low maintenance requirements, and intriguing behaviors. One behavior that often piques the curiosity of their owners is their tendency to bury themselves. In this blog, we will explore the reasons behind this behavior and shed light on the fascinating world of crested geckos.

Understanding Crested Geckos


Crested geckos are native to New Caledonia, a group of islands in the Pacific Ocean. They are arboreal reptiles, which means they spend most of their time in trees. Their bodies are adorned with unique features such as a prehensile tail, specialized toe pads for climbing, and eyelids. These geckos are primarily nocturnal, active during the night, and resting during the day.

Burying Behavior in Crested Geckos


One intriguing behavior often observed in crested geckos is their burying behavior. In this blog section, we will explore the reasons behind this behavior, its significance, and how you can provide the ideal environment to support this natural instinct in your pet crested gecko. So, let’s dig deeper into the world of burying behavior in crested geckos and uncover the secrets hidden beneath the soil!

A. Observing the burrowing tendencies in crested geckos

Crested geckos often exhibit a natural inclination to bury themselves, especially during the day when they are resting. It is not uncommon to find them partially or completely buried in the substrate of their enclosure.

B. Factors that influence buying behavior

Environmental conditions (humidity, temperature, lighting)

Crested geckos are sensitive to changes in environmental conditions. Burrowing behavior may be influenced by factors such as temperature and humidity. Buried geckos can regulate their body temperature better by seeking cooler or warmer areas within the substrate.

C. Individual personality and temperament

Just like humans, crested geckos have their own unique personalities. Some individuals may be more inclined to burrow as a way to seek solitude and security, while others may exhibit this behavior less frequently.

D. Stress and security factors

Crested geckos are generally shy and prefer secure hiding spots. Burrowing allows them to create a safe space where they feel protected from potential threats or stressful situations.

Potential Reasons for Burying


If you’re a proud owner or an aspiring enthusiast of these remarkable reptiles, you’ve probably witnessed their intriguing habit of burying themselves in the substrate or hiding beneath objects in their enclosure. But have you ever wondered why they engage in this behavior? 

In this blog section, we will explore some potential reasons behind this burying behavior. From natural instincts to environmental factors, we’ll delve into the various explanations that shed light on this fascinating phenomenon. So, let’s embark on a journey of discovery and uncover the hidden motivations behind crested geckos’ tendency to bury themselves!

A. Thermoregulation

How burrowing aids in temperature regulation

Buried geckos can find cooler or warmer areas within the substrate, enabling them to regulate their body temperature. This behavior helps them stay comfortable and maintain their metabolic processes.

Maintaining a comfortable and optimal body temperature

By burying themselves, crested geckos can avoid extreme temperature fluctuations, which can have adverse effects on their health and well-being.

B. Moisture Regulation

How burying helps regulate humidity levels

The substrate in which crested geckos bury themselves can retain moisture, thus creating a microenvironment with higher humidity levels. This can be beneficial for their skin health and respiratory functions.

Preventing dehydration and skin issues

Burying can help prevent dehydration by reducing the rate of water loss from the gecko’s body. It also helps keep their skin adequately moist, preventing issues like shedding problems or dryness.

C. Camouflage and Protection

Blending in with the environment for safety

Crested geckos have natural camouflage abilities, and burying themselves enhances their ability to blend in with their surroundings. This makes it easier for them to remain hidden from predators or potential threats.

Evading predators and minimizing risks

Burying helps crested geckos minimize their chances of being detected by predators, allowing them to stay safe and avoid unnecessary risks.

D. Breeding and Reproduction

Nesting behavior for egg incubation

Female crested geckos may bury themselves when they are preparing to lay eggs. This behavior provides a protected environment for the eggs, mimicking the natural nesting conditions found in the wild. The buried eggs are shielded from predators and fluctuations in temperature and humidity, increasing the chances of successful incubation.

Ensuring the survival and development of offspring

By burying their eggs, female crested geckos create a favorable environment for the development of their offspring. The stable conditions provided by the buried eggs promote proper embryonic development, increasing the likelihood of hatching healthy hatchlings.

Encouraging Burying Behavior in Captivity

To promote and support burying behavior in captive crested geckos, it is important to create a suitable enclosure that mimics their natural habitat.

A. Creating a suitable enclosure

Vertical space: Provide a tall enclosure with plenty of climbing opportunities, as crested geckos are arboreal by nature.

Substrate: Choose a suitable substrate that retains moisture, such as coconut fiber or moss. This allows the gecko to burrow comfortably.

Hiding spots: Offer various hiding spots throughout the enclosure, such as cork bark tubes or dense foliage, to give the gecko a sense of security.

B. Providing appropriate substrate options

Moisture retention: Ensure the substrate maintains a level of moisture that aids in humidity regulation for the gecko.

Depth: Provide a substrate depth that allows the gecko to partially or fully bury itself, providing them with a range of options based on their preference.

C. Offering hiding spots and secure environments

Decorative elements: Add plants, branches, and another decor to create hiding spots and visual barriers that give the gecko a sense of security.

Climbing structures: Install branches or vines to encourage natural climbing behavior and provide additional hiding places.

D. Monitoring and maintaining optimal environmental conditions

Temperature: Maintain a temperature gradient within the enclosure, allowing the gecko to choose their preferred temperature range.

Humidity: Regularly monitor and adjust the humidity levels within the enclosure to ensure it aligns with the gecko’s needs.

Lighting: Provide a suitable lighting setup, including a day-night cycle, to mimic natural lighting patterns.


Understanding the reasons behind crested geckos burying themselves allows us to provide a more enriched and suitable environment for their well-being in captivity. By recreating their natural habitat, we can encourage their natural behaviors and provide them with the security, comfort, and conditions they need to thrive. 

Burying behavior in crested geckos is a fascinating adaptation that showcases their innate instincts and should be respected and supported as part of responsible care for these amazing reptiles.
