Frog's Fanny Double-Duty Fly Treatment
Match the hatch by coating your nymphs with Frog's Fanny. It will put an air bubble around them that looks just like an emerging insect.
Odorless, tasteless, and non-toxic
Instructions: To treat a fly, either a dry fly or a nymph, simply dip the brush in Frog's Fanny and spend a few seconds working the powder into the fly. The more you work it in, the happier you will be with its performance. Use the brush! If you try to shortcut by putting the fly in the powder and shaking it up a little, you will not be happy. If you use the brush, you will be delighted with your results.
