I've had mine now for a couple of months and have kept them in a bin in our closet. No smell or noise, as I can hear the crickets in the front room over our son's monitor. The roaches have not shown any desire to get out of the bin since we've had them. We've seen the mating and the sacks, but until I can see I'm overwhellmed with them will I actually feed heavily from them. Only a male here and there....
There was a time when I was cleaning the bin and a male escaped. I didn't know it until I found him in the room later. They are easily retrieved by a pair of tweezers or tongs by the wings or antenea. My larger female seems to really like them.....
