Well im in college and have shared a dorm with muh roomy and my "our", mascot of room 214, ambilobe Syd for few semesters now. When I first showed my roomy Syd he was so impressed he didn’t care all that much about the bugs, although he did express how unpleased he would be if he found any crawling around the room. Show you’re roomy the cham, get em all warmed up to the idea, then explain the bug situation; don’t stink, don’t fly, don’t climb, no noise. Show em or don’t show em up to u.
Firstly before you make it public that you have a cham in your room you need to look up your schools bylaws on pets in dorms. Most schools have a 10gal tank max and others have an only "fish" policy, and most would certainly have issue with insects in your dorm in fear of infestation. My school happens to be all the above, but my RA and I are cool so he doesn’t care. So basically become bf's w/ your RA and if he/she is a chill RA, buy him/her a 12pk and you’ll be set.
I would suggest keeping dubias in a 10gal tub tucked away DEEP in your closet, up high if possible. So that nobody goes rummaging and finds its contents. Never ever let anybody know you have a colony of hundreds or thousands of roaches or the wrong person may find out and then you’re screwed. idc what kind of bug it is, but if a person who don’t like bugs ends up seeing your bugs, they will automatically think it’s a monster cockroach from the bowels of NYC that is attempting to eat them, specially dubias because adults get rather large, and then u magnify that by your colony size, see where I’m going? But keep that as your staple food and your biggest secret.
Because chams require variety, once a week or so I'll go buy a couple dozen crickets and feed them with the dubias. I keep the crickets in a Qt sized wonton soup container I got from yummy yummy chinese delivery. I keep this out of general sight as well, out of sight out of mind, but occasionally somebody will ask what they eat. It's a lot easier to show and/or explain a couple crickets in a small lidded container than thousands of roaches. People seem to be more acceptable of crickets than roaches, I think it has a lot to do with jiminy cricket. And for sake of insanity, rip or cut the males wings off. The males r the ones without the sticks coming out there ass. Nothing is more annoying than chirping crickets and your roomy wont hate you as much. Whenever theres a reptile expo ill go and get silkies or something as a treat. Usually have them around here every other month.
A couple nice benefits of having a cham at school, free gutload and great ice breaker/conversation piece. Just take some salad, fruits from the DC. They usually have a good assortment of things. If you’re a dude then having the cham is like having a puppy with the girls and if you’re a girl then… come on what kind of guy wouldn’t be fascinated by your cham?
So that’s the basics on how I do things, gL in school.
