I was having a very bad possom problem here and a couple of raccoon / fox problems innermixed , to make a long story short , I stopped at 2 pet groomers here and asked if they would hold their floor sweepings ( cut dog hair ) for me and they did I spread it out about 50 ft from my pens in a row a couple of feet wide ,, have not had a single attack sense then , I kept going to the groomers and now have some in reserve , seems to work .
