Not spray the dubia, mist the sides of the tub if the humidity is low. As for mold. if the food is kept in a shallow bowl it should not mold. The bedding im using actually resists mold like it would in any vivarium (frog or tropical invertibrate vivarium etc) When I upgrade to a larger tub I will not use bedding. This was a good jump-start for my colony. The warmer and more humid it is, the more they reproduce, the less chance there is of young ones dying from not being able to properly molt. They are tropical, not desert insects. As for the tub being clear, its kept in the closet in the snake room. Plenty dark with an ambient temp of at least 80/85 at all times and sometimes higher during the day. They cant chew through the screen. At least the roach breeder I talked to said they could not. As for males flying. IO have only seen them flutter to the ground if picked up. If they can actually gain some lift and distance thats news to me. It must be a rare occurance.

"Water should be supplied by water gel as it does not get stinky the way sponges will. Using water gel insures against immature roaches accidentally drowning. A dish of water gel also raises the humidity inside the enclosure so that misting the sides of the tanks is not necessary. Blaptica dubia are more tolerant of a lack of moisture, more so than most other species as evidenced by a lack of dying. However, these roaches prefer more moisture than many other species and consequently breed better."
