Crushed Egg Shell

Crushed egg shell is a natural, calcium-rich supplement that supports healthy exoskeleton development in isopods and other invertebrates. Finely ground shells help maintain strong, well-formed shells and carapaces, promoting successful moults and long-term colony health in bioactive setups and terrariums.

In wormeries, crushed egg shell plays a vital role in balancing pH and aiding digestion. The fine grit helps worms process organic matter more efficiently, while the slow-release calcium improves overall compost quality. Regular use can reduce acidity, creating a more stable and productive environment for composting worms.

As a sustainable by-product, egg shell calcium is an eco-friendly choice for keepers of isopods, springtails, snails, millipedes and other inverts. It can be mixed into substrate, added to leaf litter, or lightly sprinkled over feeding areas. Combined with quality leaf litter and decaying wood, it forms part of a complete, natural diet for thriving invertebrate cultures.
