hi there,
Maybe i can help you. I have for the past 2 months been using Dubia roaches for my baby as well. I got i belive around 250-300 mixed sizes with adults and i read where you were worried about escapes... well how does this sound...
The only ones that can climb are the babies, which you can stop by putting packaging tape, sticky side out around the inside of teh tub you use a few inches away from the top. They cant fly, jump, dont move very fast (incase you drop one) the only thing that bothers me are their sticky feet, they can hang on to something for dear life,lol, but it only takes a minute to shake them lose... most people cut a small hole in the top of the tub about 4x4 to allow for ventalation, then they cover the hole with screening, i hot glued mine to the tub top,lol, yes despite what everyone was saying i was TERRIFIED they these guys would escape... now if you happen to drop one and it runs off and you cant find it, have no fear because these guys are tropical roaches, (CORRECT ME IF I'M WRONG) but they need a temperature of atleast 80-85 to survive, so if you have one escape turn on the air condition in the house,lol. now they do need a higher temp that than to breed, but i'm just talking about survival...
I hope i have helped you in some way!!!!
Good luck
oh, by the way, i have a picky dragon as well, but it only took him SEEING the roaches and he went crazy, i mean he got in his hammock and was trying to leap out of his viv to get to them. now he will show me where their tub is (just incase i forget ya know,lol)
