A premium fermented substrate crafted from European hardwoods, perfect for isopods, millipedes, and beetle larvae.
Flake Soil is a specially prepared breeding substrate made from crushed, milled, and fermented oak and beech wood. Through a careful composting process, the wood breaks down into a nutrient-rich, easy-to-digest material that invertebrates thrive on. This 1L portion is ideal for hobbyists wanting to try flake soil without committing to larger quantities, or for topping up existing enclosures.
What is Flake Soil?
Unlike standard substrates, flake soil has been pre-fermented—meaning the tough cellulose and lignin in the wood has already begun breaking down. This makes it far more digestible for detritivores and provides a ready source of nutrition. The fermentation process also encourages beneficial microorganisms that support a healthy enclosure ecosystem.
Ideal for:
Isopods – Works brilliantly as part of a substrate mix for Cubaris species and other tropical varieties. Combine with coconut coir, sphagnum moss, and leaf litter for an enriched environment that supports burrowing behaviour and healthy moulting.
Millipedes – An excellent primary substrate for millipede keeping, providing both nutrition and a comfortable medium for burrowing.
Beetle larvae – Originally developed for rhinoceros beetle and stag beetle breeding, flake soil remains the gold-standard substrate for rearing larvae to their full potential.
How to Use
Flake soil is supplied slightly dried for storage stability. Before use, gradually add dechlorinated water and mix thoroughly until you achieve the desired moisture level—it should hold together when squeezed but not drip. Allow it to rest for 24 hours before introducing your invertebrates.
For isopod enclosures, flake soil works best as part of a layered substrate. Use it alongside your existing mix to add variety and nutrition. It pairs perfectly with springtails in bioactive setups, as both will work together to process organic matter and maintain a clean, balanced environment.
