This premium fermented substrate is made from 100% Quercus acutissima (Japanese evergreen oak) sawdust, which has been researched over many years to be the most effective for rhinoceros beetles. It is finished using Himalayan Oyster Mushroom mycelium, a top-tier new mycelium.

Several types of special amino acids and bacterial agents that promote the growth of Japanese rhinoceros beetle larvae have been added.

By incorporating bacteria, the symbiotic microorganisms within the digestive tract that break down cellulose (a protein source) become more active, improving nutrient absorption.

Feeding this from the early larval stages leads to larger adult sizes.

Experiments have shown that larvae raised on this premium fermented substrate, rich in symbiotic microorganisms like internal bacteria, grow significantly larger than those raised on commercially available substrates.

The new mycelium made from Quercus acutissima sawdust is crushed and slowly triple-fermented for an extended period in a controlled indoor environment.
(We do not use waste mycelium discarded by mushroom farms, unlike cheaper substrates from other companies.)

This is the ultimate, meticulously crafted substrate, completed with significant time and high costs.

Most common fermented substrates from other companies use waste mycelium from mushroom farms as their raw material, resulting in reduced nutritional value.

Furthermore, inexpensive substrates are often fermented outdoors, leading to the inclusion of various insects and fly eggs, which can infest your breeding setup.

Our Fermented Substrate is carefully fermented indoors using only new mycelium, ensuring a 100% absence of insect contamination, so no unwanted insects or flies will appear during breeding!

We have a high repeat customer rate of over 90% due to the popularity of this substrate, with many Guinness-sized beetles successfully emerging.

Himalayan oyster mushroom mycelium, which rhinoceros beetles and stag beetles prefer most, is expensive and difficult to obtain.

Himalayan Oyster Mushroom Fermented Substrate is recommended as food for Japanese rhinoceros beetle larvae and as a substrate for egg-laying.

There are numerous reports of Japanese rhinoceros beetles reaching 88mm in size.

There is also a record of a single female Japanese rhinoceros beetle laying 90 eggs.
