I've personally never used it, but hear it works. The commercial stuff, can't think of the name of it is supposedly H2O2 or has some in it. Here's a couple of tips I use in Arkansas. Didn't see where anyone mentioned the use of a Coleman lantern, it will work so much better than any flashlight I have ever used, it will really make the blood shine. Don't forget to carry spare mantles either. Don't know if everybody has these little critters, we call em granddaddy longlegs, (spider) with legs about 2 inches long, at night on a light blood trail look for them, most often if you have more than one in a spot, they are usually on the blood.
