Leopard geckos are fascinating creatures that make great pets for reptile enthusiasts. If you’re a new owner of a leopard gecko, or you’re considering getting one, you may be wondering what kind of food to feed them. One of the most popular options for feeding leopard geckos is mealworms. Mealworms are easy to find, relatively inexpensive, and provide a good source of protein for these carnivorous creatures.

However, you may be wondering if it’s safe and healthy to feed your leopard gecko mealworms. In this blog, we’ll explore the nutritional benefits and potential risks of feeding your leopard gecko mealworms, and provide some tips on how to safely incorporate mealworms into your pet’s diet.

So, Can Your Gecko Eat Mealworms?


Yes, leopard geckos can eat mealworms. In fact, mealworms are a popular food choice for leopard geckos and are widely available as feeder insects. Mealworms are a good source of protein and are relatively easy to digest, which makes them a great food option for leopard geckos.

When feeding mealworms to your leopard gecko, it’s important to make sure they are the appropriate size. Ideally, the mealworms should be about the same size as the space between the gecko’s eyes. This ensures that the gecko can easily swallow the mealworm without choking or experiencing any digestive problems.

It’s also important to provide a varied diet for your leopard gecko, so feeding them only mealworms is not recommended. A diet consisting solely of mealworms can lead to nutrient deficiencies, especially in calcium and vitamin D3. To ensure a balanced diet, it’s recommended to offer a variety of feeder insects, such as crickets, dubia roaches, and waxworms, as well as occasional treats like fruit and vegetables.

When feeding mealworms to your leopard gecko, it’s important to also consider the nutritional value of the food that the mealworms are being fed. Mealworms that are raised on a high-quality diet will be more nutritious for your gecko than those that are raised on a poor diet. You can also “gut load” the mealworms before feeding them to your gecko by feeding them nutritious food like carrots, kale, or apples for a day or two prior to feeding them to your leopard gecko.

In summary, leopard geckos can eat mealworms as part of a balanced diet. However, it’s important to ensure that the mealworms are an appropriate size, and to offer a variety of other feeder insects and treats to ensure a balanced diet. Additionally, the nutritional value of the mealworms can be improved by “gut loading” them before feeding them to your leopard gecko.

Nutritional Benefits of Mealworm


Leopard geckos are insectivores and require a diet that is high in protein and low in fat. Mealworms are a popular food choice for leopard geckos and offer a variety of nutritional benefits.

  • Protein:

Mealworms are an excellent source of protein, which is essential for growth and development. Protein is also needed for muscle maintenance, repair, and the production of enzymes and hormones. Mealworms have a protein content of about 20-25%, making them an ideal food source for geckos.

  • Fat:

Leopard geckos require a low-fat diet, and mealworms offer just that. Mealworms are relatively low in fat, with a fat content of around 13-20%. This makes them a great food option for geckos who are prone to obesity.

  • Calcium:

Calcium is crucial for strong bones and healthy teeth, and geckos require a diet that is high in calcium. Mealworms are a good source of calcium, with a calcium-to-phosphorus ratio of 1:7. This ratio is ideal for geckos as it ensures that they are getting enough calcium without the risk of developing calcium deficiencies.

  • Phosphorus:

Phosphorus is important for cell function, bone development, and energy metabolism. However, too much phosphorus in a leopard gecko’s diet can lead to calcium deficiencies. Mealworms have a phosphorus-to-calcium ratio of 7:1, which is within the recommended range for geckos.

  • Vitamins and Minerals:

Mealworms are also a good source of vitamins and minerals that are essential for leopard gecko health. They contain vitamin B12, which is important for nerve function and the production of red blood cells. They also contain vitamin E, which helps support the immune system, and minerals such as zinc and iron, which are important for overall health.

In conclusion, mealworms are an excellent food source for geckos due to their high protein content, low fat content, and balanced calcium and phosphorus levels. They also provide essential vitamins and minerals that are necessary for a healthy and balanced diet. However, it’s important to remember that mealworms should not be the only food in a leopard gecko’s diet, and their diet should be supplemented with a variety of insects and occasional fruits and vegetables.

How Do You Prepare Mealworm For Your Gecko?


Preparing mealworms for your gecko is a simple process. Here are the steps to follow:

  1. Purchase live mealworms from a reputable pet store or online vendor.
  1. Store the mealworms in a container with a substrate of oatmeal, wheat bran, or cornmeal. Keep the container at room temperature, and provide slices of potato, carrot, or apple as a moisture source.
  1. Before feeding the mealworms to your gecko, you can dust them with a calcium supplement to ensure your gecko gets enough calcium in their diet.
  1. Offer the mealworms to your gecko by placing them in a shallow dish or directly on the substrate in their enclosure. Remove any uneaten mealworms after a few hours to prevent them from burrowing into the substrate.
  1. Monitor your gecko’s feeding behavior and adjust the number of mealworms offered accordingly. Overfeeding can lead to obesity and other health issues.

Remember to always provide fresh water and a balanced diet for your gecko to ensure their health and well-being.


In conclusion, mealworms are a suitable food source for geckos and are a common staple in their diet. However, it is important to provide a balanced diet with variety to ensure your gecko is receiving all the necessary nutrients. It is also crucial to avoid overfeeding mealworms, as they have a high fat content and can lead to obesity if consumed in excess.
