Leopard geckos are popular reptile pets that are loved for their striking appearance, docile nature, and relatively easy care requirements. As with any pet, providing a nutritious and balanced diet is essential to their health and well-being. While mealworms are a common staple in many leopard gecko diets, some owners may wonder if it’s safe to offer their gecko mealworm beetles as a food source. 

In this blog, we’ll explore the topic of whether leopard geckos can eat mealworm beetles, the nutritional value of these insects, and any potential risks associated with feeding them to your pet. So, if you’re a leopard gecko owner or simply curious about reptile nutrition, read on to learn more.

So, Can Your Gecko Eat Mealworm Beetles?


Leopard geckos are popular reptile pets that require a well-balanced diet to thrive. They are insectivorous, meaning they primarily feed on insects, and mealworms are one of their favorite foods. However, when it comes to mealworm beetles, the answer is a bit more complicated.

Mealworm beetles are the adult form of mealworms. While leopard geckos can safely consume mealworms, the same cannot be said for their beetles. Mealworm beetles have a hard exoskeleton that can be difficult for leopard geckos to digest. Additionally, mealworm beetles contain high levels of chitin, a type of fiber that can be difficult for leopard geckos to break down.

Consuming too many mealworm beetles can lead to impaction in leopard geckos. Impaction occurs when an animal is unable to pass waste through its digestive system, and it can be a serious and potentially life-threatening condition. Symptoms of impaction in leopard geckos include lack of appetite, lethargy, and constipation.

While it is not recommended to feed your leopard gecko mealworm beetles, if your gecko accidentally ingests one, it is not usually a cause for immediate concern. However, you should monitor your gecko closely for any signs of impaction and contact a veterinarian if you notice any unusual symptoms.

In summary, leopard geckos should not be fed mealworm beetles as they are difficult to digest and can lead to impaction. It is best to stick to feeding your gecko mealworms or other insects that are easier for them to digest and offer a well-rounded diet.

Nutritional Benefits of Mealworm Beetles

While mealworms are a staple food for leopard geckos, mealworm beetles can also provide nutritional benefits for these reptiles. Here are some of the detailed nutritional benefits of mealworm beetles for leopard geckos:

  • Protein:

Mealworm beetles are a great source of protein for leopard geckos. They contain about 23-25% protein, which is similar to the protein content of mealworm larvae. Protein is essential for leopard geckos as it helps them grow and develop properly, maintain muscle mass, and support the production of enzymes and hormones.

  • Fat:

Mealworm beetles are low in fat, with a fat content of around 7-10%. This makes them an ideal food source for leopard geckos who require a low-fat diet to prevent obesity.

  • Calcium:

Calcium is critical for leopard geckos as it supports bone growth, development, and maintenance. Mealworm beetles are an excellent source of calcium, with a calcium-to-phosphorus ratio of 1:1. This ratio ensures that leopard geckos receive adequate amounts of calcium without the risk of developing calcium deficiencies.

  • Phosphorus:

Phosphorus is another essential mineral that leopard geckos require for proper bone development and energy metabolism. Mealworm beetles contain a phosphorus-to-calcium ratio of 1:1, which is also within the recommended range for leopard geckos.

  • Vitamins and Minerals:

Mealworm beetles contain several vitamins and minerals that are essential for leopard gecko health. They are a good source of vitamin B12, which is necessary for nerve function and red blood cell production. They also contain vitamin E, which supports the immune system, and minerals such as zinc and iron, which are important for overall health.

  • Chitin:

Mealworm beetles are rich in chitin, a tough, fibrous substance that makes up the exoskeleton of insects. While chitin is not digestible, it can help improve leopard gecko digestion and prevent impaction by promoting the movement of food through the digestive tract.

In conclusion, mealworm beetles can provide leopard geckos with a variety of nutritional benefits, including protein, calcium, phosphorus, vitamins, minerals, and chitin. However, it’s important to note that mealworm beetles should be fed in moderation and should not be the sole food source for leopard geckos. A balanced diet consisting of a variety of insects, fruits, and vegetables is essential for leopard gecko health and well-being.

How Do You Prepare Mealworm Beetles For Your Gecko?


Feeding mealworm beetles to your gecko can be a nutritious and easy way to provide them with a source of protein. Here are the steps to prepare mealworm beetles for your gecko:

  1. Purchase live mealworm beetles from a pet store or online retailer.
  1. Place the beetles in a plastic container or tub with a lid. Line the container with a layer of bran or oatmeal as a substrate for the beetles to live on and lay their eggs in.
  1. Provide the beetles with a source of food, such as fruits or vegetables, to keep them healthy and active.
  1. Allow the beetles to reproduce and lay eggs in the container. The eggs will hatch into mealworm larvae, which can also be fed to your gecko.
  1. Once the beetles have reached maturity, remove them from the container using a spoon or tweezers and place them in a separate container.
  1. Dust the beetles with a calcium or vitamin supplement before feeding them to your gecko. This will help ensure that your gecko is receiving all of the necessary nutrients from their diet.
  1. Place the dusted beetles in your gecko’s feeding dish and monitor their intake. Be sure to remove any uneaten beetles from the dish after a few hours to prevent spoilage.

It’s important to note that mealworm beetles should not be the sole source of protein in your gecko’s diet. They should be offered in addition to a balanced diet of gut-loaded insects, vegetables, and fruits to ensure your gecko is receiving all of the necessary nutrients.


In conclusion, while leopard geckos can technically eat mealworm beetles, it is not recommended to feed them to your pet as a regular part of their diet. Mealworm beetles are not as nutritious as mealworm larvae and can potentially cause impaction or other digestive issues. It is best to stick to feeding your leopard gecko mealworms, dubia roaches, crickets, or other appropriate insects.
