The roaches now have a lamp and heat bulb rather than a heating pad. I've been meaning to add the following for a while, but kept forgetting: Dubia roaches are often marketed as"Quiet". I have found this is not entirely true, as they produce a skittering sound. If you fall asleep easily, this probably won't bother you at all, but if you are like me, it may keep you awake. For me especially, the nature of the sound keeps me awake, and I have to drown it out with a large box fan at night. It's kinda funny to me, considering crickets don't really bother my sleep with chirping, only occasionally bothering me by jumping and hitting the top/sides of the tank.
