We all have a few tips and tricks that we use year after year. Whether it be for convenience or a solution, they just may help another hunter to pass those along the way. First and most handy at times for me is a spray bottle of peroxide. We have a small 89 cent spray bottle and keep it full of peroxide....about 2.00 total. Whenever a tracking job is questionable, the peroxide goes with us. Blood will definately foam and there is no question if those little red spots are blood or not.
