I use wire cages but cut a few rows off the top to shrink it down a bit. I jam in as much bait as possible so the roaches can chew on some of it and have a reason to hang around. If the seals are around I'll also zip tie in a couple of DrakePucks (

) in case the cages get smashed up.
Not having to buy bait is key for me going OFTEN. One hobie bait tank plugged with macks gives me enough bait for seven trips. I go to LJ and can usually bang that out in a couple of hours.
