Some people who come over to visit have nothing on them, I noticed if I do not get them off right away they seem to get under the skin and are just ugly and aggravating , sometimes quite annoying. I have been to Dr. and Skin Specialist ,with no results. I always shower reg. ,use Dial or Dove soap for years .I have a tremendous amt. of large trees in my yard ,Oak, Pin Oak,etc. Last year and this year I noticed quite a bit of mold on the Lawn and some has worked in through a bad roof and floor of my mobile. Anyone having similar situations. My Dr. is very smart but He just jokes and says consider them your little friends.
