Thank you for viewing.

Limited Sale!!

This listing is for one block of spent mushroom substrate for *Dorcus hopei binodulosus*.

Please see the 20 photos above.

This is a very large block.

You can add as many as you like!

This spent substrate block is made from 100% raw oak sawdust and is packed with nutrients.

As you can see in the photos, 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 with logs, and you can obtain a large number of larvae!

*Dorcus hopei binodulosus* 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 the larvae of stag beetles such as *Dorcus hopei binodulosus*, *Dorcus hopei*, rainbow stag beetles, and giraffe stag beetles!

It's also suitable for breaking apart to create your own original fermented substrate.

*The photos are of one item from our stock.
Please only purchase if you understand that some blocks may be slightly broken or have different shapes.*
