Wow its funny you guys are talking about chiggers. I was just talking about them to a friend that lives out in the south. I had asked him how do u get read of them once u got them. I guess most folks use clear nail polish to put over the bit. Its suppose to keep them from getting air. I did a search and found that chiggers are a larva. They are microscopic and they feed on ur skin. Once the bites start to itch and get pimpely the chigger has already fallen off ur skin. I guess deet is one of the best ways to prevent them and some type of powder.
In Texas they call them "Red Bugs". I found out last year when my feet and legs were destroyed by them...I went to 3 drugs stores asking if they had anything for Chiggers and they thought I was nuts. The fourth drug store had a fella from Georgia that said "they hurt don't they" and you got bit by red bugs.
He gave me some special stuff that really worked...it was like clear nail polish with lanagain (spelling) Killed the itch and killed the little bugs
