I think Heatheranne was saying squeeze juice on the cubes, not on the roaches. And Yoshimi mentioned the babies in the separate bin don't get heat, but that his adults do. Not trying to be a jerk, just pointing out that both their points look fine.
I would also like to add my experience and two cents. I haven't found any solid proof that oranges provide any extra incentive to breed, I think it's more about hydration, which most fruits provide anyway. That being said, blaptica dubia really don't mind being a little cramped, as long as you practice the proper husbandry.
This is just my personal experience, but when I feed my roaches it's the adults that get to the dinner table first. When I come back to remove what's left a few days later, it's the babies I see sucking the last drops from the rind.![]()
