This is a listing for a used substrate block from a Giant Stag Beetle culture.

Please see the 10 photos above.

This is a very large block.

Additional blocks are available for purchase!

This is a used substrate block made from 100% raw oak sawdust, offering excellent nutritional value.

As you can see in the image, the mycelium is firmly established within the block.

Simply bury the block as is in the substrate, and stag beetles will lay eggs!

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

Antaeus 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 this in the substrate.

It's also excellent as food for larvae of stag beetles that prefer fungal substrates, such as Giant Stag Beetles, Stag Beetles, Rainbow Stag Beetles, and Giraffa Stag Beetles!

It's also suitable for creating your own original fermented substrate by breaking it apart.
