Should find a photo of Clorox Bleach. Number one sting relief if applied nearly immediately. Big yellow jacket or hornet got me on Tuesday while I was standing in a pond, couldn't put bleach on it til I got out. Granted, my instinct since beekeeping caused me to grab yellow jacket gently and throw it so as not to inject more venom by whacking it. But I scratched sting open when I got to shore and smeared on a good amount of bleach, instant relief. One benadryl I took 30 minutes later as it was feeling like it MIGHT swell. a little purple mark that night, healing now.
