We camped in northern N.Carolina in 2015 (fall) with our fw and got them. Did the treatments, sprays and such and we stopped finding any. We decided to change to a MH a few months ago and we bought from private seller. All clothes were washed before transfer and everything else was closely checked just to be sure we didn't move any to the new (to us) coach. We closely check the fw for any before we sold it. All good, then we have found 4 or 5 in the new coach in the last month or so. Don't know if we moved them, or they were with the new coach.
