Thanks Danz. After reading your post, I did a google search and it basically had the same information so you were spot on. The only thing is, it said nail polish will not work, yet I get relief from itching for days, that starts immediately upon application so there is something in it that definitely DOES help me. I also wonder if I'm not allergic or overly sensitive, because the article said the itching only lasts 2-3 days and the bites are healed in 2 weeks, but in my experience, the itchings lasts for weeks and you could still see my last batch of bites after a month. I find the same thing with mosquito and flea bites too though - they seem to last much longer than most people's experience so I guess I'm allergic to insect saliva.
