We've been using Permanone AKA Duranon for almost twenty years...Its the only thing made that will keep ticks off of you, period...you treat your clothes with it (socks, pants, shirt)...you can wash your clothes a time or two in between treatments...I also use the large velcro ties (24") around the bottom of my pants or tuck them in my boots...it either comes in a yellow can with a green top, a yellow can with a black top, or a blue and orange can with a blue top (repel brand)...the active ingredient is permethrin (.5%)...walmart carries it here, when they have it in stock...they seem to run out often...
