Worm Castings

Worm Castings — Nature's Superfood for Isopod Enclosures

Worm castings — also known as vermicompost — are one of the most nutrient-dense natural bioactive terrarium supplies for terrariums and isopods. Produced by earthworms breaking down organic matter, these fine, crumbly castings are packed with goodness and work wonders in both the substrate and as a direct food source for your colony.

Why Worm Castings Benefit Isopods

• Exceptional nutrition — Rich in nitrogen, phosphorus, potassium, and trace minerals that support healthy growth, successful moulting, and strong exoskeleton development.
• Thriving microbiome — Packed with beneficial bacteria, fungi, and microorganisms, worm castings supercharge the microbial life in your enclosure.
• Natural food source — Isopods will actively graze on worm castings, making them an excellent supplemental food that can be mixed into the substrate or offered directly.
• Improves substrate quality — Mixed into your substrate, worm castings improve moisture retention, aeration, and overall structure.
• Supports the decomposition cycle — Perfect for clean-up crews and healthy ecosystems, the microorganisms in worm castings accelerate the breakdown of organic matter.
• Completely natural & safe — Free from synthetic additives and safe for all isopod species, springtails, and other vivarium inhabitants.

A high-quality organic material for bioactive setups UK-wide, suitable for reptiles, amphibians, and microfauna habitats, as well as all isopod species including Porcellio scaber, Armadillidium vulgare, Cubaris sp., and many more.
