Limited Sale!!

We are offering a set of 3 used substrate blocks for Giant Stag Beetles.

Please see the 20 photos above.

These are quite large blocks.

Additional blocks are available for any quantity!

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

As you can see in the images, 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 are easy to break apart, making it easier than using logs to extract larvae, and you can obtain a large number of them!

Ants 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 the larvae of stag beetles that prefer fungal substrates, 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.
