Hi, I have several colonies. Dubia roaches are quite prolific. 3-5 months for nymphs to mature and females birth approx 30 babies a month.
There is no significant smell, only if you stick your head in or right over the bin.
Let me know if you have any other questions. I have Dubia available at my site www.PhillyFeeders.com
