The Permethrin spray from Sawyer on your clothes is definitely the way to go. I now use that on my clothes (socks, pants, shirt), along with 95%+ DEET spray on my body. One caution is that Permethrin is very toxic to cats, so keep the spray and the clothes away from any cats (assuming you aren't trying to poison them) until everything is dry. At that point it is supposed to be safe, but I typically try an be cognizant of leaving any of my hiking stuff laying around in the house where one of the cats could potentially come in contact/lay on it.
I spend a LOT of time in the woods off-trail and pretty much every trip out during the summer you would come home w/ at least a couple. I used to not use anything, but one trip last month I came back with 17 ticks :( Some were picked of during the day, but I found like a dozen when I got back home that night and did a thorough inspection and I decide that it was time to make some changes. Since using the Permethrin sprayed clothes and the DEET I haven't had any more show up.
Ticks in general weird me out a bit, but seed ticks are another level of
