100%. The Dubai roaches are like the Hissers, as soon as they reach a certain colony size, then all of a sudden you will find yourself with so much roaches that you have no idea what to do with them all. Best advice, split the colony. Sell a few and buy more containers as the 95L containers I use cost R280+ and then you need more dry mix, and expensive stainless steel mesh etc etc
But I just sell most of my colonies off, once. So that it will take some time for the colony to recover. A year minimum. At that stage you would most probably also buy a few new roaches, just to keep your colony strong "blood line" but most will not. It all depends on you

good luck and keep us all posted
