I like the toilet paper tube idea. I have been battling the decision to start a roach colony because I have a very intense fear of roaches. I am still working on finding my big girl panties so I can get over it, but I like the idea of not having to touch them. This would be nice and easy to clean as well. I ALSO think that this would work for crickets which is what I use now. I hate the beasts, but they don't wig me out like roaches do...but still, most of the posts on this site make me feel like a bad owner for not feeding roaches!
