Here at Josh’s Frogs, we keep our Blaptica dubia roaches in large opaque Sterilite brand plastic tubs. Darker tubs allow Blaptica dubia roaches to remain active 24/7, resulting in faster growth and reproduction. Because Blaptica dubia roaches cannot climb smooth plastic, a top is not needed, and allows for proper ventilation. Glass aquariums work, just note that Blaptica dubia nymphs will climb silicone, so a tight-fitting screen top is a must when culturing Blaptica dubia in glass containers.
Heat is provided by a 150w ceramic heat emitter positioned above the culture. Another option to heat Blaptica dubia roaches would be a heating mat. Keeping Blaptica dubia roaches warm is important, as the warmer Blaptica dubia roaches are kept, the faster Blaptica dubia roaches will reproduce.
High humidity is also important, which we provide by providing a substrate of 2 inches of coco bedding that we routinely add water to. You do not want the Blaptica dubia culture to be soaking wet, but you do not want it to be dry. We find that Blaptica dubia roaches breed faster, smell less, and are just as easy to maintain by providing a substrate in the Blaptica dubia culture.
Cardboard Egg Crate provides places for Blaptica dubia roaches to hide and give birth. Blaptica dubia roaches will spend most of their time hiding in the egg crate. The egg crate can be positioned vertically or horizontally in Blaptica dubia roach cultures, but we find simply laying the egg crate horizontally works well. Excess debris can be cleared from the egg crate by gentle shaking. Blaptica dubia roaches tend to cling to the egg crate when it is picked up, and ca be removed by shaking. Larger Blaptica dubia roaches tend to fall off sooner than smaller Blaptica dubia roach nymphs, and can be sorted by size in this manner.
