YES. They sting me and make me cough, especially at night, or when I am meditating, or any time that I am about to fall asleep. It is as if they don't want me to sleep or meditate. And they itch the skin on my neck where I use to have a wart that felt like it was stabbing me. I removed it with bloodroot. Bloodroot is what stops them. I think I have convinced them that they are defeated. They are hrumf and non responsive at the moment.
