Nasty little buggers.
I found out that when they bite, I use a cotton ball soaked with rubbing alcohol and rub it for about a minute. It stops the burn, itch and swelling almost instantly!!
If I don’t catch them within a few minutes I get large pimple like sores which I scratch at night until they bleed and then it’s a mess for a week.
Same for mosquito bites!!
I had numerous welts and small pustules on the back of my hand, and boy, did they sting. Quite painful.
