DIRT — the perfect substrate for isopods, millipedes + beetles (Large Bag)

Approximately 5.5 lbs 

A simple, honest mix I actually use in my own bins. DIRT is built to feed your crew and hold shape, not turn swampy or dusty. Just pour it in, add a leaf layer on top, and watch the clean-up crew get to work.

What makes it great

• Ready to use: pre-chopped, blended, and sifted—no extras needed to get started.
• Long-term food + structure: real flake soil (fermented hardwood) keeps nutrition coming while the mix stays diggable.
• Moisture that behaves: holds humidity evenly without getting mucky when you mist one side.
• No nonsense: no fertilizers, no pine, no perlite—safe for detritivores and bioactive builds.

Ingredients

Organic compost, chopped leaf litter, chopped sphagnum moss, flake soil (fermented hardwood).

How I use it

• Base depth: 5–10 cm (2–4 in) for isopods; 10–15 cm (4–6 in) for millipedes and beetle larvae that like to bury.
• Moisture: keep one side a bit wetter, one side drier; adjust to your species.
• Top layer: add extra leaf litter and a small piece of cork or bark for cover.
• Upkeep: refresh the leaf layer as it disappears; mix in a little fresh DIRT or flake soil every month or so for heavy eaters.

Good for

Isopods (beginners to fancy Cubaris), millipedes, and many beetle larvae that benefit from fermented hardwood in the mix.

What it’s not: potting soil, straight coco, or a peat-heavy blend. DIRT is made for detritivores first—plants can still do fine, but the recipe is tuned for the bugs.

Resealable stand-up pouch keeps things tidy between uses.
