Feeding Leopard Geckos: Can They Eat Dubia Roaches?


Leopard geckos are fascinating reptiles known for their unique appearance and low maintenance needs. As responsible pet owners, it is crucial to understand the dietary requirements of these geckos to ensure their well-being. While commercial gecko food is readily available, some reptile enthusiasts prefer to vary their pets’ diets by feeding them live insects, such as Dubia roaches. In this article, we will discuss whether leopard geckos can eat Dubia roaches and the potential benefits and risks associated with this feeding practice.

Can leopard geckos eat Dubia roaches?

Yes, leopard geckos can safely consume Dubia roaches as part of their diet. Dubia roaches are one of the most nutritious feeder insects available for reptiles and are packed with essential nutrients that contribute to the gecko’s overall health. These roaches are a suitable addition to a leopard gecko’s diet, provided they are appropriately sized and offered in moderation.

The nutritional profile of Dubia roaches

Dubia roaches are rich in protein, which is crucial for the growth and development of leopard geckos. Additionally, they contain healthy fats, vitamins, and minerals that contribute to the reptile’s overall well-being. These nutrient-packed insects also have a low chitin content, making them easily digestible for leopard geckos compared to other feeder insects.

Feeding tips and guidelines

It is essential to follow some guidelines when feeding Dubia roaches to leopard geckos:

  1. Size matters: Choose Dubia roaches that are an appropriate size for your gecko. The rule of thumb is to offer prey that is not wider than the widest part of the gecko’s head. This ensures your gecko can comfortably swallow and digest its food.
  2. Variety is key: While Dubia roaches offer excellent nutrition, it is crucial to incorporate variety into your gecko’s diet. Include other feeder insects such as crickets, mealworms, and waxworms to provide a well-rounded nutritional intake.
  3. Feed in moderation: Although Dubia roaches are highly nutritious, they should not form the sole component of your gecko’s diet. Aim for a balanced diet consisting of 70% commercially available gecko food and 30% live insects.
  4. Gut load and dust: Before offering Dubia roaches to your gecko, ensure they have been properly fed and hydrated. This process, known as gut loading, enhances the insect’s nutritional content. Additionally, dust the roaches with calcium and vitamin supplements to ensure your gecko receives adequate nutrients.

Risks and precautions

While Dubia roaches are generally safe for leopard geckos to consume, there are a few risks and precautions to consider:

  • Escapees: Dubia roaches are excellent climbers and can escape from their enclosure if not secured properly. Ensure your gecko’s habitat is escape-proof to prevent potential harm or unwanted infestations in your home.
  • Size mismatch: Be cautious when selecting the size of Dubia roaches for your gecko. Offering insects that are too large can lead to choking or digestive issues. Always consider the size and age of your gecko when choosing suitable prey.
  • Quality control: When purchasing Dubia roaches, ensure they come from a reputable breeder. This helps guarantee the roaches are free from any potential contaminants, such as pesticides or diseases, which could harm your gecko.


Dubia roaches can be an excellent addition to a leopard gecko’s diet, providing the necessary nutrients for their growth and overall well-being. When feeding these roaches, it is crucial to consider size, variety, and moderation. While there are some risks, following proper precautions can ensure a safe and enriching feeding experience for your leopard gecko.
