Hydrogen peroxide (3% solution) is a very powerful tool for blood trailing. Any little spec of blood, no matter how old or dried, will turn white and frothy as soon as the peroxide hits it. This tool can help you find blood when it isn’t visible to the naked eye, such as after a rain, mud, thin grass, crop fields or dry pine needles.

Hydrogen peroxide should be kept in a colored bottle so it doesn’t break down; the easiest and safest thing to do is to attach a spray nozzle to the actual peroxide bottle. However, I keep mine in a clear bottle, but it’s clearly marked, wrapped in a towel and kept under my truck seat until I need it.
