I made a bin similar to
@WashingtonCham 's post because I think this setup provides so much ventilation that I don't find it to be that stinky at all! I have a rubbermaid bin that I cut out the sides and top of, hot glued aluminum mesh to the cutouts. I also find that these bins have rounded corners - easier to clean than an aquarium tank in my opinion. I keep the crix in there with plenty of egg crates. I use bottle caps for water crystals and a dry food blend. I just put the gutload veggies and fruits on the bottom of the bin.
Every week or so I clean it out by using a bathtub scrub brush to collect all waste in one area. I literally use toilet paper rolls and baby spoons to scoop it all out and into a zip lock bag or plastic grocery bag (something I can seal the smell away). Then maybe every other time I do this (so every other week or so) I use a diluted (very diluted) vinegar mixture in a small spray bottle and paper towels to wipe the bottom really well because it gets gross. I don't remove the crickets when I do this, and it has never seemed to harm or kill them. I simply move the egg crates to one side, clean it, and then just do the other side. It is annoying with crickets trying to get in your way, but having one cham means I don't have a ton of crickets and it's not an issue for me. Also, to be on the safe side, I never clean using the vinegar spray within 24 hours of feeding my cham crickets.
