Crested geckos have become popular pets due to their unique appearance and docile nature. As responsible owners, it’s essential to provide the best care possible, which includes maintaining proper humidity levels within their enclosure. Many owners wonder if it is safe to spray their crested geckos with tap water. 

In this blog post, we will delve into the topic, examining the habitat requirements of crested geckos, assessing tap water quality, discussing the risks associated with using tap water, exploring safe alternatives, and providing best practices for maintaining optimal humidity levels.

Understanding Crested Gecko’s Habitat Requirements:

To provide the best possible care for your crested gecko, it’s crucial to understand their natural habitat and moisture needs. Crested geckos are native to the tropical rainforests of New Caledonia, where humidity levels are high. In captivity, recreating this environment is vital for their overall health and well-being. Proper humidity levels promote healthy shedding, hydration, and overall respiratory health.

Crested geckos have evolved to thrive in a humid environment, as it helps them regulate their body temperature and maintain proper hydration levels. In their natural habitat, humidity levels can reach up to 80%. Therefore, it is essential to replicate these conditions as closely as possible in their enclosure.

Assessing Tap Water Quality:

Before deciding whether tap water is suitable for misting your crested gecko, it’s important to consider the quality of your tap water. Tap water typically contains chemicals like chlorine and chloramines, which are added to kill bacteria and other microorganisms. While safe for human consumption, these chemicals can be harmful to reptiles.

Chlorine and chloramines can cause skin irritation, respiratory issues, and even damage to the gecko’s delicate skin. In addition to these chemicals, tap water may also contain heavy metals, pesticides, and other impurities that can be harmful to your gecko.

Water conditioners specifically designed for reptiles can be used to neutralize chlorine and chloramines. These conditioners are readily available in pet stores and are an essential investment for the health of your crested gecko. They work by binding to and neutralizing these harmful chemicals, making the water safe for your gecko to drink and minimizing the risks associated with tap water usage.

It’s important to note that tap water quality can vary depending on your location. Different water treatment methods and sources can result in variations in the chemical composition of tap water. Therefore, it’s always a good idea to check with your local water supplier for more information on the specific water quality in your area.

Risks of Using Tap Water:

While tap water may be safe for human consumption, it can pose risks to crested geckos when used for spraying. One of the primary concerns is the sensitivity of the gecko’s skin. Their delicate skin can become irritated when exposed to chemicals present in tap water, leading to dryness, redness, and even skin infections. This is particularly true if the gecko has any existing skin conditions or wounds.

Moreover, tap water may contain contaminants beyond chlorine and chloramines. Heavy metals such as lead, copper, and zinc can be present in tap water, and long-term exposure to these substances can be detrimental to the health of your gecko. Additionally, tap water can also contain pesticides, herbicides, and other impurities that may have adverse effects on your gecko’s overall well-being.

Safe Alternatives for Spraying Crested Geckos:

Given the risks associated with tap water, it’s advisable to explore safe alternatives for misting your crested gecko. One excellent option is distilled water. Distilled water undergoes a purification process that removes impurities, including chlorine, chloramines, heavy metals, and other contaminants. It provides a clean and safe source of hydration for your gecko without the risk of skin irritation or exposure to harmful substances.

Distilled water is widely available in stores and can be used for misting your crested gecko’s enclosure. It is important to note that distilled water lacks the minerals present in natural water sources. However, these minerals can be provided through a well-balanced diet and the use of calcium and vitamin supplements.

Another alternative is to use pre-made reptile-safe sprays that are specifically formulated for misting reptile enclosures. These sprays are designed to provide the ideal moisture and hydration for crested geckos without any harmful additives. They often contain beneficial ingredients like aloe vera, which can provide additional benefits for the gecko’s skin.

When using alternative water sources or reptile-safe sprays, it’s crucial to ensure that the spray bottles and misting equipment are clean and free from any contaminants. Regularly rinse and clean the spray bottles to prevent the growth of bacteria or mold that could harm your gecko.

Best Practices for Humidity Control:

While choosing the right water source is crucial, it’s equally important to follow best practices for maintaining optimal humidity levels in your crested gecko’s enclosure. Here are a few tips to help you create an ideal environment for your gecko:

  1. Use a hygrometer: Invest in a reliable hygrometer to monitor the humidity levels in the enclosure. This device will allow you to accurately measure and maintain the desired humidity range, which is typically between 50% and 70% for crested geckos.
  2. Mist regularly: Misting the enclosure with distilled water or reptile-safe sprays helps increase humidity levels. The frequency of misting will depend on your gecko’s needs and the ambient humidity levels in your home. Typically, misting once or twice a day is sufficient. Observe your gecko’s behavior and adjust the misting schedule accordingly.
  3. Focus on the enclosure setup: Ensure that the enclosure is properly sealed to retain humidity. A glass or acrylic terrarium with a tight-fitting lid is ideal for maintaining humidity levels. Provide adequate hiding spots and live plants within the enclosure, as they can help create microclimates with higher humidity.
  4. Monitor shedding patterns: Crested geckos shed their skin regularly, and maintaining proper humidity levels is crucial for successful shedding. If you notice difficulties or incomplete sheds, it may indicate that the humidity is too low. Adjust the misting schedule or make necessary modifications to the enclosure to optimize humidity for healthy shedding.
  5. Avoid over-misting: While humidity is essential, excessive moisture can lead to problems such as mold growth or respiratory issues. Find the right balance by monitoring the humidity levels and adjusting misting accordingly. Proper ventilation is also crucial to prevent excessive moisture buildup.


Maintaining optimal humidity levels is essential for the health and well-being of your crested gecko. While tap water may contain chemicals and impurities that can be harmful to your gecko, there are safe alternatives available, such as distilled water and reptile-safe sprays. 

By understanding the risks associated with tap water and following best practices for humidity control, you can ensure a comfortable and thriving environment for your crested gecko. Remember to always prioritize the health and safety of your pet by providing appropriate care and researching reputable sources for husbandry guidance.
