Nah, they actually seem to roam quite a bit and get caught in glue traps really easily. I was alerted to the problem by seeing 18 or so on a glue trap that had been out for a previous mouse hunt. Once I closed up the hole and put out some Roach Motels, I've only caught 2 or 3 in the past week. I think the problem's all but taken care of,... I'm not sure how more than 2 or 3 dozen total could have gotten out. Just sucks lol...
