Tea tree oil works for me have been using for years. Just don't ever saturate a hanky with it and slip it against your skin for any lenghth of time as it will cause almost like a chemical burn. It is also a natural astringent, antiseptic & antifungal. I douse about five shakes to hands rub together apply around ankles especially and all over (except those special spots) as you will holla like it's hot. You can wipe residual on your hair and the scent is pleasant. Ok hope that helps happy squito fighting. Enjoy Paradise
