We have tons of rats, tried poison, they don't eat it. We have 2 ratinator traps; they are like a maze. Put bait in the center and the rats go in, can;t get back out. Record so far, 54 between the 2 traps 2 weeks ago, but you have to drown them in a tray. This reduced the population some but still keep coming. Our local feed store recommended putting honey on the bait, will be trying that soon.
