These are newly emerged adult dubia roaches, not retired breeders. Some females may even begin producing shortly after receiving them! The male to female ratio in these groups are perfect for breeding your own dubia. Dubia Roaches are one of the best feeder insects due to their great nutrition profile, inability to fly, jump or climb smooth surfaces, minimal odor, and hardiness. Not to mention, almost all reptiles love them! We raise all of our dubia roaches and feed them the best food for optimal nutrition. Bananas, carrots, apples, and grains are just a few of the foods in our roaches diet. We do not feed them any animal protein. (No Shipping to Florida, Hawaii, or Alaska.) Live Arrival Guaranteed!
