I wish I'd known about this a bit sooner!
I had a day recently when bees were landing on me right and left; luckily, those were on my shoulder and shirtfront so I could see what they were and be aware that I needed to avoid them until they flew away. The next evening I wasn't so lucky; one landed on the back of my knee and the edge of my shorts must have brushed it when I walked. I pulled the stinger quickly and came in for the baking soda, but it didn't seem to do all that much to relieve the symptoms. Next time I'll try the ammonia.
Thanks, Ann!
