Skin So Soft doesn't do s**t, in my opinion.
I'd be willing to try the stuff Oak recommends, but for now I use Off. I don't get bitten a lot and tend to stay out of the woods at this time of year, but today I did go for a hike in the local conservation land. I sprayed my clothes and legs/arms, and no bites. I did get swarmed by these little fleas that were buzzing around my head. Don't know what these suckers are, but they have been around for a couple of weeks. I guess I need to spray my head, but I had just come from getting my hair colored and I thought one chemical was enough!
