Haha I call out a challenge then, a springtail bin vs canyon bin. My canyons literally clean up piles of old food and dead roaches within days, your springtails can't touch them!
When you say centipedes, do you mean millipedes? Cause they were awesome cleaners for me too.
Seriously though, springtails do play a good role, I'm not dismissing them. I worded that a little more harshly than I intended. In all of my enclosures, and I've had a lot, nothing got rid of poop like the canyons. Especially for larger reptiles, like my Parsons or something much larger like a tegu, you'd need isopods to break down waste that size. On the flip side of that though, I feel springtails help break down the smaller particles and leaf litter more adding a richness to the soil. So it's a balance for sure. Springtails are easy to seed an enclosure with, even by doing nothing(as a snail keeper you know the feeling), good isopods need to be added on the other hand.
