Domino Roaches mimic a beetle as adults with black bodies and pretty white dots as their name suggests. Adults are able to climb smooth surfaces so you will need a tight lid while their nymphs prefer to stay in the substrate and are unable to climb smooth sides.
Keep warm and on coconut coir substrate or organic soil with sweet fruit like bananas and some vegetables and they will produce lots of young.
We try to send a mix of ages as the adult phase is the shortest. At times we only have mixed age nymphs to send with no adults but we try to add adults when we have enough. Contact us before ordering if that is important to you.
