Thank you for viewing.

Limited Sale!!

This is a listing for 3 blocks of spent mushroom substrate from Giant Stag Beetles.

Please see the 20 photos above.

These are quite large blocks.

Additional blocks are available for purchase!

These spent substrate blocks are made from 100% raw oak sawdust and are packed with nutrients.

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

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

They can be easily broken apart, making it easier to extract larvae than from logs, and you can obtain a large number of larvae!

Ant-type stag beetles are laying eggs prolifically!

It also enhances the nutrition for 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 larvae of myceliophagous stag beetles such as Giant Stag Beetles, Stag Beetles, Rainbow Stag Beetles, and Giraffa Stag Beetles!

They are also suitable for breaking apart and creating your own original fermented substrate!

*The image is of one block taken from our inventory.
Please only purchase if you understand that some blocks may be slightly broken or have different shapes.

This is a limited sale, so the listing will end once sold out.
