I am also raising lobster roaches and I think that
they are second only to mealworms as far as "easiness"
to raise.
I use a variety of different sized boxes with hinged
lids and peat moss as a substrate. I mainly feed them
laying mash and apple wedges.
I used to use "bug boundary" to keep them from escaping
but that didn't seem to work with the babies, so I've
started using vaseline recently and found that it works
better, except that it is a pain to deal with when cleaning
the container (how do you wash vaseline off?).
Prior to using the vaseline, the boxes I have have a thin crack at the lid hinge, so a smaller roach(and occasionally a large one) could get out if it really wanted to, but that hasn't been
too big of a problem. I keep paper towel tubes and egg crates in with them. They are less likely to climb the walls if they have some hiding places.
I've found them easy to deal with, interesting to watch and I've gotten pretty comfortable handling them. They don't bite at all(at least they haven't bitten me.)
I would say the adults and sub-adults are perfect sizes for adult boxies and then you've got a range of juveniles and babies to feed younger turtles or other reptiles.
The smallest baby roach is perfect for the smallest hatchling turtle.
Highly recommended!
