The giants won't breed for you. Just so you know, not sure if thats your intentions or not. Dubia roaches are pretty awesome, I just got started with them too. NO smell, they can't climb much, they can climb a little though I've found out. They're live bearers, so you dont have to deal with laying boxes, and they dont eat the babies, so they dont have to be seperated like crickets. Most importantly they make basically NO!!! noise. They do have a very very quiet hiss if they're disturbed, but you have to be paying attention in a quiet room to hear it.
