Thank you for viewing.

Limited Sale!!

This is a set of 5 used mushroom substrate blocks for Ohira beetle.

Please see the 20 photos above.

These are quite large blocks.

Additional blocks are available in any quantity!

These used substrate blocks are made from 100% raw oak sawdust and are highly nutritious.

As you can see in the photos, the mycelium is firmly embedded within the blocks.

Simply bury the blocks in the substrate, and stag beetles will lay eggs!

They are easy to break apart, making it easier to extract larvae than from wood, and you can obtain a large number of larvae!

Anteaters are laying eggs in abundance!

It also enhances the nutrition of rhinoceros beetle larvae.

When raising rhinoceros beetle larvae, you'll notice a significant increase in size simply by burying these blocks in the substrate.

They are also excellent as food for the larvae of stag beetles such as giant stag beetles, stag beetles, rainbow stag beetles, and giraffe stag beetles!

They are also suitable for breaking apart to create your own original fermented substrate.

*The photos show one of the items from our inventory.
Please only purchase if you understand that some blocks may be slightly broken or have different shapes.
