This is the best destription of a chigger that I have found....& it's right on with the itching just getting worse & worse.

Bad me, the other day when I was taking a shower, all my bites started to itch intensely......so I started to scratch with the washcloth....needless to say, now my legs are covered with scabs. Luckily, the itch isn't near what it was to start....but my legs look horrible with 100's of bites all over my legs.....I look like I have the chicken pox. I think what really helped to start with was that I put some mud stuff that I used to use years ago on my face, all over my legs.....it was like green mud.....wow did I look strange walking around with green mud plastered legs...lol.....what a sight.
