A rich, loam‑heavy substrate designed specifically for burrowing spiders and other fossorial invertebrates. This 1‑litre bag provides a stable, moisture‑holding base that supports deep tunnels, secure hides and natural behaviour in the enclosure.
Why this soil works so well
High loam content: Holds shape beautifully, allowing spiders to create strong, lasting burrows.
Moisture‑retentive: Keeps humidity stable without becoming waterlogged.
Mould‑resistant blend: Ideal for long‑term setups and sensitive species.
Natural texture: Mimics the feel of compact forest or jungle floor.
Perfect for burrowing species
Tarantulas: Asian terrestrials, fossorial species, and juveniles that prefer deep substrate.
Trapdoor spiders: Supports tunnel construction and stable door anchoring.
Burrowing roaches: Encourages natural digging and sheltering behaviour.
Beetle larvae: Provides a firm, nutritious medium for tunnelling.
Other inverts: Any species that thrives in deep, structured substrate.
How to use
Fill enclosures with 10–20cm depth for fossorial spiders.
Pack down firmly to help the soil hold shape.
Maintain gentle moisture for species that require humidity.
Combine with cork bark or rotten wood for added structure and enrichment.
