So I just had a colony of several hundred Reticulitermes flavipes die off after around a month in captivity (spoiler for next journal update), and I'm wondering if it's because I fed the colony cardboard. They were kept in a container w/ cardboard rolled up, the idea being that they'd live in and eat the stuff. The container was kept in a larger container along w/ other termite colonies, the larger container having a layer of water at the bottom to regulate humidity. Thus I'm fairly certain that environmental factors (moisture, heat) didn't kill the colony, as the other colonies in the same container w/ different setups are alive and doing well. So the only factor I haven't accounted for is cardboard.
I vaguely remember reading somewhere that someone (was it Vendayn?) warned against keeping termites in cardboard, because it can sometimes contain harmful glue. Does anyone else have experience w/ termite death related to cardboard? Or has anyone kept colonies successfully in cardboard setups?
