This mushroom substrate is made from 100% oak sawdust, which stag beetles love, and finished with the highest quality Himalayan Oyster Mushroom mycelium.
It has a sweet, mushroomy scent.
Even with the same mushroom substrate, those finished with Himalayan Oyster Mushroom mycelium are most preferred by stag beetles, resulting in larger adult beetles.
Himalayan Oyster Mushroom substrate is expensive and difficult to obtain.

It can be used as food for the larvae of all types of stag beetles, both domestic and foreign.
(Suitable for species that prefer mushroom substrate like Giant Stag Beetles, Rainbow Stag Beetles, Flat-headed Beetles, Sawtooth Stag Beetles, etc.)

The Himalayan Oyster Mushroom substrate was produced in a controlled indoor environment, then crushed and bagged.
They eat it voraciously!
The key to raising large adult stag beetles is to feed the larvae plenty of high-quality food during their larval stage.
With good quality substrate, stag beetle larvae will continue to eat heartily!
Their feeding response is different, allowing you to aim for super-large sizes!

It's versatile for use in bottles, portioning into pudding cups, or mixing with fermented substrate, offering an economical alternative to mushroom bottles.
You can also create your own fermented substrate by adding additives to this mushroom substrate.
We also have fermented substrate that has been fermented for a long time indoors and turned black. Please check my other listings.
The black fermented substrate is a versatile substrate that can be used for rhinoceros beetles as well as stag beetles.
Some users who consistently win top prizes in Be-Kuwa contests are loyal users of the Himalayan Oyster Mushroom substrate.
No gas release or watering is necessary; it's ready to use.

*This substrate is not for making mushroom bottles.
*Himalayan Oyster Mushroom substrate is precious and the harvestable amount is very small. During peak ordering periods, shipping may take some time.

*The size of the emerged adult beetle can vary significantly depending on the bloodline and breeding environment, such as temperature control.
For those seeking only size in mushroom-substrate-loving stag beetles (Giant Stag Beetles, Flat-headed Beetles, Rainbow Stag Beetles, Sawtooth Stag Beetles, etc.), I recommend the Himalayan Oyster Mushroom Bottle listed separately.
