The first time I used it, I went hiking in a place known to be a tick mecca. I found several dead ones in the laces of my boots and in the cuffs of my pants. I've been a convert ever since.
And when I say permethrin all the things, I mean it. My clothes, hat, hammock, backpack, etc. I want to leave a trail of dead ticks in my wake when I go hiking or camping.
