They aren't actually in your skin, it is just a bite. I had always heard that too, but it is a myth. Fingernail polish can stop the itch, but most of it has formaldahyde in it (yuck). The main concern from chigger bites (other than the desire to scratch yourself to death) is infection. I am trying to keep them clean. I have a little thing of TTO that has some alcohol in it along with some other thngs (I think it is that little bottle from Burt's Bees for blemishes), that is actually working. It doesn't last long, but sometimes a temporary reprieve is all I can ask for!
