Knowing what to feed your mealworms and mealworm beetles can have a significant impact on their health and the well-being of their predators. This article will explore the dietary needs and preferences of these insects, highlighting the best food options to ensure they maintain a healthy and balanced diet.

What Do Mealworms and Mealworm Beetles Eat?

Mealworms and mealworm beetles have a diverse and adaptable diet, allowing them to thrive in various environments. They can consume a wide range of plant-based materials, including:

Dry grains such as oats, cornmeal, and rice Fruits and vegetables like potatoes, sweet potatoes, lettuce, apples, and bananas Decaying organic matter Bread crumbs and other food waste

While they can eat a variety of substances, it's crucial to provide them with a balanced diet for their optimal health. This includes high-protein chow, vitamins, and minerals, which are essential for their growth and development.

Enhancing the Diet with Supplemental Foods

Some enthusiasts suggest adding supplements to the mealworms' diet, such as cuttlefish bone for calcium intake. This not only benefits the mealworms but also enhances the nutrition of their predators. Homemade beetle jelly, a favorite among mealworms, can be prepared using a blend of sugar, iodized salt, and water. Some also use oats as bedding and include “bug grub” as a supplementary food source.

The Importance of High-Quality Feeding

Ensuring the mealworms are fed the best possible diet is crucial, especially if they are to be used as food for reptiles. Many pet stores offer commercial mealworm food that is formulated to meet the nutritional needs of these insects. Before purchasing, it is essential to check the sources of the mealworms and mealworm beetles to ensure they are raised under optimal conditions. Reputable breeders and pet supply stores often provide information on the diet and care of these insects, which is important for maintaining their health and reducing the risk of introducing pathogens to your reptiles.

Feeding Practices and Tips
