This is a fermented substrate made from 100% oak sawdust, which stag beetles prefer, and finished with the highest quality Himalayan King Oyster Mushroom mycelium.

We've further refined ordinary Himalayan King Oyster Mushroom substrate into fine particles for easier consumption, and added triple the amount of nutritional supplements such as trehalose, glucose, chitosan, royal jelly, special amino acids, and symbiotic bacteria, making it a specially selected premium substrate.

We do not use any discarded substrate. Instead, we crush new substrate made from fresh sawdust and ferment it slowly indoors.

This is our ultimate, meticulously crafted substrate, triple-fermented with significant cost and time investment.

Most other companies' fermented substrates use discarded substrate, leading to the proliferation of unwanted insects and fruit flies. However, our substrate is completely free of such contaminants.

Thanks to the large individuals consistently produced, this substrate has a very high repeat customer rate.

Even with the same mycelium, substrate finished with Himalayan King Oyster Mushroom mycelium is most preferred by stag beetles and results in larger individuals.
Himalayan King Oyster Mushrooms are expensive and difficult to obtain.
This substrate can be used as food for larvae and as a laying substrate for all types of stag beetles, including Japanese and foreign species.

It is suitable for Miyama Stag Beetles and Sawtooth Stag Beetles.

You can also raise Sumatran Stag Beetles, Japanese Giant Stag Beetles, and Rainbow Stag Beetles with this substrate.

Naturally, it can be used for all types of rhinoceros beetles.

The substrate is made by crushing and fermenting new substrate, and it contains triple the usual amount of nutritional supplements, resulting in outstanding nutritional value.

The key to raising large adult stag beetles is to feed the larvae plenty of high-quality food during their larval stage.

Our high-calorie, nutritionally superior Himalayan King Oyster Mushroom Premium Mycelium Fermented Stag Beetle Substrate is the pinnacle of larval food.

It has produced Guinness-sized Miyama Stag Beetles.

Unlike using pre-made mycelium bottles, this substrate offers greater versatility and economic benefits when packed into jars or small containers like pudding cups.

We regularly receive orders from stag beetle shops nationwide and have received high praise.

Some users of this fermented substrate have won top awards multiple times at Be-Kuwa contests.

Not only is it excellent for feeding larvae, but it also results in a large number of eggs when used as a laying substrate.
