The best thing that worked for me was hair. The lady at my hair salon saves all the hair in a trash bag for me, then I go to the dollar store and get the strongest, cheapest perfume they have and I spray it on the bag full of hair. Give it a good shake. And then I sprinkle the hair in and around the flower beds. The perfume makes it last a while longer.....that human smell. I have also tried Irish spring soap. But have had better luck with the hair.
