Thank you for viewing.

Limited Sale!!

We are offering 3 blocks of spent mushroom substrate for Giant Stag Beetles.

Please see the 10 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 in your substrate, and stag beetles will lay eggs!

They are easy to break apart, making it easier to extract larvae than with 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 these blocks in the substrate.

They are also excellent as food for larvae of stag beetles that prefer mushroom substrate, such as Giant Stag Beetles, Stag Beetles, Rainbow Stag Beetles, and Giraffa Stag Beetles!

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