Well dont know if it will actually kill the little so*s on the horse but if I've got any they are history! New Nettex product comes in plastic puffer pack, but actually more like top of a pepper pot so quite messy. I duly clipped feathers and tried to puff product on most of it went on the floor and me , massaged the rest into horses legs but actually dont think it went down to skin as ned has extremely thick hair. So will monitor legs now and see if any improvement!
