Crested geckos are beloved reptile pets known for their unique appearance and docile nature. As responsible owners, it’s essential to understand the dietary needs and preferences of these fascinating creatures.

While mealworms are a nutritious food source, they should be offered as a supplement rather than a primary diet for crested geckos.

In this blog, we will explore the question of whether crested geckos eat mealworms and provide insights into their nutritional requirements and feeding options.

Crested Gecko Diet


Understanding the dietary needs of crested geckos is crucial for their overall health and well-being. In this section, we will explore the natural diet of crested geckos in the wild, the availability of commercial crested gecko diets, and the occasional supplementation with fruits. By delving into their dietary requirements, we can ensure that our crested geckos receive the nutrition they need to thrive.

A. Natural diet in the wild:

In their native habitat of New Caledonia, crested geckos primarily feed on a variety of insects, nectar, and fruit. Their diet consists of small invertebrates, such as crickets, roaches, and moths, along with the occasional consumption of ripe fruit.

B. Commercial crested gecko diets:

To replicate their natural diet in captivity, various commercially available powdered diets are formulated specifically for crested geckos. These diets provide a balanced combination of essential nutrients and are convenient for pet owners to offer as a staple food source.

C. Fruit supplementation:

While commercial diets provide most of the required nutrients, some crested gecko owners choose to offer small amounts of fruit as a supplemental treat. Fruits like mashed bananas or apricot can be provided occasionally to add variety to their diet.

Nutritional Needs of Crested Geckos


Proper nutrition is vital for the optimal health of crested geckos. In this section, we will discuss the specific nutritional needs of crested geckos, including their requirements for calcium, phosphorus, and vitamin D3. By understanding these essential nutrients and their roles, we can provide a well-balanced diet to support the overall health and development of our crested geckos.

A. Calcium and phosphorus requirements:

Crested geckos require adequate calcium for healthy bone development and phosphorus for metabolic functions. It’s crucial to maintain the correct calcium-to-phosphorus ratio in their diet to prevent health issues like metabolic bone disease.

B. Vitamin D3 supplementation:

To aid in calcium absorption, crested geckos require an appropriate source of vitamin D3. This can be achieved through exposure to natural sunlight or by providing artificial UVB lighting in their enclosure.

C. Balancing protein and carbohydrate intake:

Crested geckos require a balance of protein and carbohydrates in their diet. The commercial crested gecko diets are carefully formulated to meet these nutritional requirements and provide a well-rounded diet for optimal health.

Mealworms as a Feeding Option


Mealworms are a popular feeder insect, but are they suitable for crested geckos? In this section, we will explore the use of mealworms as a potential dietary option for crested geckos. We will discuss their nutritional profile, the advantages, and disadvantages of incorporating mealworms into their diet, and provide guidelines for their proper use as a supplement to ensure the nutritional needs of our crested geckos are met.

A. Overview of mealworms:

Mealworms are the larvae of darkling beetles and are a common feeder insect for reptiles. They have a high protein content and are readily available at pet stores or can be bred at home.

B. Suitability for crested geckos:

While mealworms are a nutritious food source, they should be offered as a supplement rather than a primary diet for crested geckos. Mealworms have a high phosphorus-to-calcium ratio, which can disrupt the necessary balance in their diet if fed excessively.

C. Mealworm feeding guidelines:

When offering mealworms to crested geckos, it’s crucial to ensure they are appropriately sized for the gecko’s age and size. Additionally, mealworms should be gut-loaded with nutritious food and dusted with calcium and vitamin supplements before feeding to provide optimal nutrition.

Alternatives to Mealworms


While mealworms are commonly used as feeder insects, there are alternative options available for feeding crested geckos. In this section, we will explore alternative feeder insects, such as dubia roaches and crickets, that can provide variety and additional nutritional benefits. By considering these alternatives, we can expand the diet of our crested geckos and cater to their preferences while maintaining a balanced nutritional intake.

A. Dubia roaches:

Dubia roaches are an excellent alternative to mealworms, offering a balanced protein-to-calcium ratio. They are highly nutritious and can be bred or purchased as feeder insects.

B. Crickets:

Crickets are another common feeder insect option for crested geckos. They provide variety in the diet and can be an exciting food source for these active hunters. However, some owners may find crickets challenging to manage due to their jumping and chirping tendencies.

C. Other options:

Other feeder insects like black soldier fly larvae (phoenix worms), waxworms, or other small roaches can also be considered as feeding options for crested geckos. These alternatives provide additional variety in the diet and can help cater to the individual preferences of your gecko.

Feeding Considerations and Best Practices

Feeding our crested geckos involves more than just selecting the right food. In this section, we will discuss important feeding considerations and best practices to ensure the health and well-being of our crested geckos. We will cover topics such as proper prey size, gut loading and dusting feeder insects, and the importance of monitoring dietary balance and overall health. By implementing these practices, we can promote optimal nutrition and support the long-term vitality of our crested geckos.

A. Feeder insect size:

It’s essential to offer appropriately sized prey items to your crested gecko based on their age and size. This ensures that they can consume the prey safely and avoid any potential choking hazards.

B. Gut loading and dusting:

To enhance the nutritional value of feeder insects, it’s recommended to gut-load them by feeding them a nutritious diet prior to offering them to your gecko. Additionally, dusting the insects with a calcium supplement and occasionally with a vitamin supplement helps ensure your gecko receives essential nutrients.

C. Monitoring dietary balance and health:

Regularly assess your crested gecko’s weight, body condition, and overall health to ensure that its dietary needs are being met. If you notice any changes in appetite, behavior, or appearance, it’s advisable to consult a reptile veterinarian to address any potential health concerns.


Crested geckos have specific dietary requirements, and while mealworms can be offered as an occasional supplement, they should not be the sole component of their diet. Commercial crested gecko diets, supplemented with occasional fruits and other feeder insects like dubia roaches or crickets, provide a more balanced and nutritionally complete diet.

By understanding the nutritional needs of your crested gecko and offering a diverse range of appropriate foods, you can ensure their health and well-being. Remember to provide proper calcium and vitamin supplementation, monitor their diet and health, and consult a reptile veterinarian for personalized advice and guidance. Offering a well-rounded diet to your crested gecko contributes to their overall vitality, longevity, and enjoyment of their life as your reptile companion.
