Ive found that ticks do not like baby powder. I powder the daylights out of me, and rub it into any clothing Im going to wear outside in the garden, and not only do they not bite, they dont even cling. Yesterday was the acid test, since I was digging in the garden, working with old leaves and last year's hay bales, and I only saw one all day. Nothing came in with me.
either they don't care for the smell, or the taste, or the texture, but for whatever reason, it works. Its also cheaper and safer than chemical/commercial sprays, and it doesnt permanently stain your clothes the way aromatic oils and Skin-so-soft does.
