I've had my colony of dubia roaches since September of 2011. I've never had a problem with them producing enough for me. In the last few months I've had an alarming amount of roach death. For awhile I wasn't sure if it was a bad batch of egg cartons or if the roaches were just reaching the end of their life cycle. It's mostly adults that are dying but I have a small amount of sub adult dying as well. It's not just a few deaths either every other day when I change their vegetables out I clean out handfuls of dead roaches. Previous to this I was able to go many months without cleaning because I was told it's best to leave them alone. I'm now changing the egg crates every week to every other week and completely disinfecting the setup because I have tons of small flies/gnats I'm even noticing small maggots, it's disgusting. I'm completely on top of cleaning and don't understand how in literally 2-3 days I find more maggots, flies/gnats, and handfuls of dead roaches.

This is incredibly frustrating because I feed all of my geckos these as their sole feeders as well as my bearded dragon. All the geckos and bearded dragon haven't had any negative effects from this but I don't know what to do. Should I start over and get a whole new colony? If so how do I safely dispose of all the roaches I have? I don't want to get an entirely new colony just to have this happen again. I'm doing everything exactly like the care sheets say.

Any ideas would be great appreciated.
