Roach Crossing’s All-Purpose Roach and Isopod Substrate

For the last decade I have honed the ultimate substrate mix for general roach and isopod keeping. This blend of airy organic material is guaranteed to maintain a stable soil pH, act as a buffer against too much or too little moisture, and provide edible shelter for various life stages of invertebrates. I have relied on it to raise most of my roach and isopod species with few modifications. This mix is bio-active which renders it infinitely more palatable to invertebrates than other, drier, sterile mixes. Please Contact Us if you have any questions regarding the mix or custom ratios!

Roach Crossing’s Premium Well-Rotted Oak Forest Leaf Mix

Of utmost importance to raising all isopods and most roaches is leaf litter. Commonly available mixes are dry, sterile leaves with no microbial activity; these are the least palatable to decomposers and offer no nutrition, leading to starvation and cannibalism. Roach Crossing’s oak leaves are well-rotted, leached of distasteful tannins, and colonized by the micro-organisms isopods and roaches really crave. These leaves are guaranteed to be free of pests such as centipedes but may contain small silver springtails and harmless free-living acari. When you see how much your invertebrates love Roach Crossing’s artisan mix of deciduous oak forest leaves, you won’t settle for brittle, sterile leaves again!
