ProRep Beetle Grub (Type A) | Specialist Beetle Larvae Food

PR Beetle Grub (Type A) is a specially prepared substrate food designed for rearing beetle larvae in captivity. Beetle larvae cannot digest raw cellulose or lignin, so standard leaf litter or wood chips are of little use without the right fungal preparation — this product solves that problem directly.

Why Fungal Preparation Matters

The key to successfully keeping and rearing beetle larvae lies in the presence of white fungus, a specific fungus that breaks down cellulose and lignin from plant material into a form the larvae can actually digest and use. Without it, larvae will not thrive regardless of what substrate they are housed in. PR Beetle Grub (Type A) is infected with and matured alongside this fungus before packaging, meaning the biological work has already been done for you.

What Type A Contains

Type A is formulated from prepared, mature broad-leaf tree leaf litter that has been processed and fungally inoculated. This makes it the leafy component in a two-part system — Type A and Type B (hardwood chip-based) are used together in varying ratios depending on the beetle species being reared, allowing keepers to tailor the mix to their animals' natural dietary requirements.

How to Use

PR Beetle Grub (Type A) is used as part of a mixed feeding substrate alongside Type B. The ratio of Type A to Type B will depend on the species of beetle you are working with — research your specific species to determine the correct blend. Both types should be used together to replicate the natural feeding environment these larvae require.

For keepers serious about beetle husbandry, having a correctly prepared, fungally active food substrate is non-negotiable. PR Beetle Grub (Type A) takes the guesswork out of larval nutrition and gives your beetles the foundation they need to develop properly.
