I live along the lake and the shore line or ditches along the road are full of it. I got my first batch this weekend on both arms. I rub it down hard with yellow soap like felsnaptha or lava soap and then pour rubbing alcohol on it. The pain makes the itch go away and then the drying starts. If I get it real bad like in my eyes or worse I get a shot and it goes away in a couple of days.
