Bran is a popular choice for mealworm bedding. It’s effective for several reasons:

Nutritional Value: Wheat bran provides essential nutrients for mealworms, supporting their growth and development.

Absorbency: It absorbs moisture well, which helps control humidity levels and prevent mould growth.

Ease of Use: It's easy to handle and replace when needed.

Burrowing: Mealworms like to burrow, and the bran's texture allows them to dig and move around comfortably.

When using bran as bedding:

Depth: Aim for a bedding depth of about 2.5-5 cm to accommodate their burrowing habits. Maintenance: Regularly sift through the bran to remove frass and old food, and replace the bedding as needed to keep the environment clean. Storage: Keep the bran dry and store it in a cool, dry place to maintain its effectiveness.

Bran can create an optimal habitat for mealworms, helping them thrive and ensuring a healthy colony.
