I just read the article and seems like a great idea. I have never had a problem with bugs but I am sure I will someday. I only see one problem.

When I tie I use my mouth a lot. Holding materials waiting to go on, wetting hair and hackle to make it go where I need it. Al mentioned a hackle that was out of the box for a week and still killed a house fly that landed on it. How is this stuff going to work on me when I forget and place a feather on my tongue? Anyone have any answers or suggestions?
