Well, I just saw this post and had to put my 2cents in!!! I started a Turkistan colony about a year and a half ago. I got them because they couldn't climb. And they can't, but here's the problem: The shipper mixed up some other kind of roach, lobsters I think, in with the shipment and everytime I moved the bin I was keeping them in, the other roaches, whatever they were, would run up the side of the bin and get out. Three months after I got them, Elvis got sick and wouldn't even eat the Turkistans so I ended up giving them away. Now, I have a roach problem in my house and my husband is so pissed at me right now. He turned on the light in the kitchen over the weekend and say a big one and a baby. I've been using bait traps, but I'm going to have to call an exterminator to get rid of these other roaches. This doesn't mean that you will have a roach problem. Just make sure before you put the bin in the house, that you didn't get some other kind of roach mixed in with non-climbing ones. If you didn't, then you will be fine and not have any roach problem. They are so much cleaner than crickets, IMHO. Well, I don't know if cleaner is the right word but the smell alone is worh it. There is no comparison: crickets just stink and roaches don't. Moral of the story, if you get non-climbing roaches, watch out for loose and fast "others" and make sure nothing gets out, just in case.
If I had it to do over, I don't think I would get the Turkistans. They have this icky sticky defense substance that's kinda gross and they are pretty fast too!
I think I would go with Dubias.
