I have never touched a roach- I lift the carton/papertowel rolls with tongs and shake it into a cup inside another container in case the cup gets knocked over or something. The first time I tried to give my beardie some, I took him into the garage and put one down in front of him. I couldn't catch it, he couldn't catch it, they are extremely fast. I'm not sure about the size of a full grown dubia, but I probably wouldn't give a full grown turkestan to a whites. They could probably handle it, just a personal preference. Plus I try not to feed off the adults. I'd say if you're still split about it, just go with the best deal you can find!
