Ohh Chiggers, I don't miss a bit about those lil' %^&*s.Trust me don't go out in the woods and get a good load of them, then come home, and climb in bed with your wife.
The only way your are going to avoid getting them and staying totally scent free is to get them and kill them when you get home. When I would get a good dose of them I used to sit 10-15 minutes in a half tub of hot bath water and two cap fulls of clorox. Took care of them!
I could handle the chiggers it was the seed ticks that really suck.[:@]
