This is a self cleaning Dubia Roach bin I made to automatically separate the poop from the roaches. Take a 1/8th inch drill bit and drill a bunch of holes in the bottom of one tote, then place it above a second tote. Cut the lid for air flow and your done. Add egg crates and roaches. Hope this helps, I know I love mine.
