New to the blaptica dubia cock roaches. I have a 1400 dubia roaches coming. They are not adults. Some a inch in length and some smaller than a 1 inch in length. How long will it take before they become established. I bought 700 from one seller and another 700 from a different seller. Should I divide them into 2 seperate bins or add them to the same bin? How long before I can start using them for the reptiles? I am educated on how to keep them. Just want to know how long it will take to get them established?
