This is a fermented mat made from the highest quality Himalayan King Oyster Mushroom mycelium, using 100% oak sawdust, which stag beetles prefer the most.

This is a special premium mat that has been further refined into fine particles to make it easier to eat than regular Himalayan King Oyster Mushroom mat, with 3 times the amount of nutritional additives such as trehalose, glucose, chitosan, special amino acids, and symbiotic bacteria.

This is an ultimateこだわり (kodawari - meticulous attention to detail) mat that has undergone 3rd fermentation over time and cost, without using any waste mycelium.

Large individuals are continuously produced, and thanks to that, the repeat purchase rate is quite high.

Even with the same mycelium, the one made from Himalayan King Oyster Mushroom mycelium is most preferred by stag beetles and rhinoceros beetles, resulting in larger individuals.

Himalayan King Oyster Mushroom is expensive and difficult to obtain.

It can be used as food for larvae and for egg-laying mats for all types of fermented mat-feeding 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, Giant Stag Beetles, and Rainbow Stag Beetles with this mat.

It can be used for all stag beetles.

The mat is made by crushing and fermenting fresh mycelium, with 3 times the normal amount of nutritional additives, resulting in excellent nutritional value.

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

With high-quality mat, stag beetle larvae will continue to eat voraciously.

This high-calorie, highly nutritious Himalayan King Oyster Mushroom premium mycelium fermented stag beetle mat is the highest quality among larval foods.

The larvae's feeding response is different, allowing you to aim for super big sizes.

It comes in a bottle, so just add the larvae! Convenient.

Can be used from the first instar.

We regularly receive orders from stag beetle shops nationwide and receive high evaluations.

Some users of this fermented mat have won top prizes multiple times in Be-Kuwa contests.

The sterilization of miscellaneous bacteria is also perfect, so no miscellaneous insects or fruit flies will appear.
