Had a problem with some kind of creature living in my basement and tried all kinds of baits to no avail. Bought one of those mouse zappers for $39.95 at HD and got several mice, but not the big guy. He disappeared,so mebbee the bait finally brought it down. Then the cocker spaniel started going crazy in the MH and we couldn't figger where the problem was. Tried several different things and finally put the zapper by the foot pedals as it seemed to be getting in thru the front ducts. Finally got him and he was so big,I had to shake him out of the zapper as he was stuck. I'm now in the process of trying to find where it was living in the MH and that's not a fun job.
Little sidw note, several folks on here said peppermint oil works at repelling them, so I picked a bunch of mint twigs and made bundles, crushed them and put them in several places in the MH. Went back several days later and they were mostly all gone,disappeared out of sight.
