Leaf Litter for Isopods (Mixed Broadleaf, 1L)

This is mixed broadleaf leaf litter: a blend of dried British hardwood leaves, birch, oak and beech among them, collected from woodland across Southern England. It is gathered away from paths, roads and dog-walking areas, then aged naturally for several months, so it is clean, dry and ready to feed. PostPods sources, selects and packs each batch by hand, so what lands in the bag is a varied mix of shapes, thicknesses and decay rates rather than a single leaf type. That variety matters, because different leaves soften and break down at different speeds and your animals like to pick and choose.

Leaf litter is the single most important food source for detritivore invertebrates. For isopods, springtails, millipedes and roaches, dried fallen leaves are not décor, they are the foundation of the diet these animals evolved to eat. On the forest floor, leaves fall, soften and grow a film of microbes and fungi, and it is this slowly rotting material that detritivores graze on day and night. Give a colony a steady supply and you see the difference: more activity, steadier moults and more reliable breeding. Run it low and animals become stressed and slow to reproduce.

Using it is simple. Lay a generous layer across the substrate surface, thick enough that you cannot see the soil beneath, and treat it as the constant base of the diet rather than an occasional extra. The colony grazes it down over the weeks and you top it up whenever the layer starts to thin; with detritivores there is little risk of offering too much. That same layer earns its keep as cover, holding humidity in the enclosure and giving mancae and juveniles somewhere safe to shelter and moult. You can use it dry or mist it lightly before it goes in; either way it soon takes up moisture from the air around it.

For a complete forest-floor base, pair it with shredded rotten wood and a scoop of flake soil, which between them cover the wood and soil sides of the diet. If you want to broaden the menu further, our Asian leaf mix and hard-wearing magnolia leaves bring in different textures and decay rates for the colony to work through at its own pace. You will find the rest of the range over in accessories. Keep the bag somewhere cool and dry, and the litter will hold indefinitely until you need it.
