Eurgh I hate them! We are very tick ridden here, I'm in the UK and where I used to live was near the "New Forest" which is tick land. My dogs' breeder, Colette, contracted Lyme Disease from a tick and I myself have had the odd one, you get used to it though and the 'don't brush into plants, lift your elbows, cover your ankles' deal has REALLY been drilled into me! Haven't had one for years now. Monty and Woody NEVER get them! They have Frontline used on them! Must be pretty good! My grandparents' collie gets them everywhere, sometimes on her eyelids
A tick twister is a must have!
I can't say anything about Permethrin as I've not used it, always used Autan because it's what my grandmother has always used and as I said, I haven't had a tick in years despite living in tick central! XDhttp://www.autan.co.uk/nqcontent.cfm?a_id=1
