Zoo Med Natural Cork Tile Background, 18 x 24-Inch

If you leave it quite bare you shouldn't have trouble locating it Just fill the bottom with 2" of invertebrate pet safe soil, apply leaf litter on top, and have a flat piece of cork line the back wall (like this or you can DIY it with chunks of cork using silicone). I also use a tile of flat cork replace the mesh lid of the enclosure to provide more crawl space they can molt from as well as to preserve stable air humidity inside (just fill any gaps with fabric or AC foam like this stuff). Then just add another piece of regular rounded cork leaning against the back wall for hiding. Leaving maimed prey near the base of its hiding spot was always successful for feeding mine.
