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

We've further refined ordinary Himalayan King Oyster mushroom substrate into fine particles for easier consumption, and added 3 times the amount of nutritional additives such as trehalose, glucose, chitosan, royal jelly, special amino acids, and symbiotic bacteria for a special premium substrate.

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

This is our ultimateこだわり (kodawari - meticulous attention to detail) substrate, fermented three times 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 consistently large individuals 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 and rhinoceros beetles, including domestic and foreign species.

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

You can also raise Sumatran Stag Beetles, Japanese 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 the nutritional additives are 3 times the normal amount, 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 outstanding Himalayan King Oyster Mushroom Premium Fermented Stag Beetle Substrate is the pinnacle of larval food.

Guinness-sized Miyama Stag Beetles have been produced with this substrate.

It is more economical and versatile than using mushroom jars, as you can fill bottles or divide it into pudding cups for various uses.

We regularly receive orders from stag beetle shops nationwide, and they have given us high ratings.

Some users of this fermented substrate have won top prizes multiple times in 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.
