trap is best!... don't use sticky paper, cuz they just get stuck.. then you have to kill them, and they dont come off.... DO NOT use poison! they eat the poison, get back into the cracks and die there, a few weeks will pass.. then you'll know you have dead rats... they crawl back into tha walls and die there and stink up the whole place, and only way to get them out is to tear the walls down..
