This is a nutrient-rich shiitake mushroom substrate block made from 100% oak raw material, which rhinoceros beetles and stag beetles prefer the most.
As you can see in the image, the mycelium is firmly established inside.
It is excellent for strengthening the nutrition of rhinoceros beetle larvae!
When raising rhinoceros beetle larvae, simply bury the block as is in fermented substrate, and the larvae will burrow into the block and eat heartily.
You will notice a significant size increase compared to raising them solely in substrate.
It can also be broken up and used as a raw material for creating your own original fermented substrate.
Some customers also use it as a substitute for spawning logs for stag beetles.
*The image is of one item from our stock.
Please only purchase if you understand that some blocks may be slightly broken or have different shapes.
We offer product and breeding support after purchase. We also have other items for sale, including unfermented mycelium substrate for stag beetles, high-calorie substrate specifically for giant stag beetles, coniferous substrate ideal for adult beetle management, perches for adult beetle breeding and display, high-grade pro jelly, and nutritional supplements.
