Crested geckos have become increasingly popular as pets due to their unique appearance and low maintenance requirements. However, one common misconception that often deters potential owners is the belief that crested geckos have a strong and unpleasant odor. In this blog post, we will delve into the truth behind this myth and provide accurate information about crested geckos and their potential odor issues.

Understanding Crested Geckos


Crested geckos, also known as eyelash geckos, are native to New Caledonia and are arboreal reptiles. They are characterized by their soft, bumpy skin and their ability to climb vertical surfaces using specialized toe pads. Crested geckos are nocturnal creatures and exhibit fascinating behaviors such as tail-waving and vocalizations.

Causes of Unpleasant Odor in Reptiles


While some reptiles may emit odors, it is important to understand the factors that contribute to an unpleasant smell. These factors include shedding and retained skin, poor enclosure hygiene and waste management, an unhealthy diet, digestive issues, infections, and illnesses, as well as stress-related factors.

Shedding and retained skin: 

Like other reptiles, crested geckos shed their skin periodically. During the shedding process, some odor may be noticeable due to the natural oils and debris that accumulate on the skin. However, this scent is usually mild and temporary.

Poor enclosure hygiene and waste management: 

If the gecko’s enclosure is not cleaned regularly, the waste buildup can contribute to an unpleasant smell. Proper waste management, including spot cleaning and regular substrate changes, is crucial in maintaining a clean and odor-free environment for your crested gecko.

Unhealthy diet and digestive issues: 

A diet lacking essential nutrients or imbalanced can lead to digestive issues, which may result in foul-smelling feces. Providing a well-balanced diet that includes commercially available crested gecko food and occasional live insects will help maintain optimal digestive health.

Infections and illnesses: 

Certain infections or illnesses in crested geckos can cause an unpleasant odor. Respiratory infections, mouth rot, or digestive problems may lead to foul-smelling breath or feces. It is important to monitor your gecko’s overall health and seek veterinary assistance if any concerning signs or symptoms arise.

Stress-related factors: 

Stress can manifest in various ways, including changes in behavior and the potential for an unpleasant smell. Loud noises, excessive handling, inadequate hiding spots, or a lack of environmental enrichment can all contribute to stress in crested geckos. Creating a stress-free environment with appropriate hiding places, minimal disturbances, and a regular handling routine can help alleviate stress-related odor problems.

Do Crested Geckos Actually Smell?


Contrary to popular belief, crested geckos do not inherently possess a strong or offensive smell. They have scent glands that secrete a mild musky scent. This scent is normal and is a way for geckos to communicate and mark their territories. It is important to differentiate between a normal scent and an unpleasant odor, which can be an indication of an underlying issue.

The typical scent of a healthy crested gecko is often described as a subtle musky or earthy odor. This scent is usually not overpowering and is most noticeable when the gecko is handled or during certain activities such as breeding or territorial disputes. It is important to familiarize yourself with the natural scent of your crested gecko to distinguish it from any abnormal odors that may indicate health problems.

Maintaining a Pleasant Environment

Proper enclosure setup and ventilation: 

A well-designed enclosure is essential for a healthy and odor-free environment. Provide a spacious enclosure with adequate ventilation to prevent the buildup of stagnant air and odors. Ensure proper temperature and humidity levels to promote your gecko’s well-being.

Hygiene practices and waste management: 

Regular cleaning routines are crucial to maintain a clean enclosure and prevent odor buildup. Spot clean any waste promptly, remove uneaten food, and clean the enclosure surfaces regularly using a reptile-safe disinfectant. Regularly change the substrate to prevent bacteria growth and odor retention.

Appropriate substrate choices: 

Choosing the right substrate is important for both the health of your gecko and odor control. Avoid substrates that retain moisture excessively, leading to bacterial growth and odor. Opt for substrates such as coconut coir or reptile-safe paper towels that can be easily replaced and provide a clean environment.

Providing a balanced diet and nutrition: 

A healthy diet plays a significant role in maintaining a pleasant-smelling crested gecko. Offer a varied diet consisting of commercially available crested gecko food, which provides essential nutrients. Additionally, supplement their diet with occasional live insects, such as crickets or roaches, to mimic their natural feeding behavior.

Health Concerns and Odor

While crested geckos do not typically have a strong odor, certain health issues can contribute to an unpleasant smell. It is crucial to monitor your gecko’s overall health and be aware of any signs or symptoms that may indicate an underlying problem, such as changes in appetite, weight loss, lethargy, or abnormal feces. If you notice any concerning odors or health issues, consult a reptile veterinarian for a proper diagnosis and treatment.

Dealing with Stress and Behavioral Factors

Stress can contribute to odor issues in crested geckos. Creating a stress-free environment is essential for their well-being and minimizing any potential odors. Provide plenty of hiding spots, branches, and foliage to create a secure and enriching habitat. Minimize disturbances, avoid excessive handling, and establish a regular routine to help your gecko feel secure and reduce stress-related odors.

Common Myths and Misconceptions

There are several misconceptions surrounding crested geckos and their odor. It is important to address these myths and provide accurate information to potential owners. By dispelling these misconceptions, individuals can make informed decisions about welcoming a crested gecko into their homes and understand the proper care required to maintain a pleasant environment.


Crested geckos do not inherently smell bad. They have a mild musky scent that is part of their natural communication and territorial marking. By maintaining a clean and appropriate environment, addressing potential health issues promptly, and minimizing stress factors, you can ensure that your crested gecko remains odor-free. 

Remember, responsible pet ownership and proper care are essential for the well-being of any pet, including crested geckos. With proper care and attention, you can enjoy the unique beauty of crested geckos without any unpleasant odors.
