Ticks are attracted to aftershave, cologne, perfumed soap , etc.
Usualy , in my area, bow season falls right in prime tick season ,so you can expect them, especialy in hard oak areas.
You can do a lot of what has been suggested so far as prevention, but if you are in the woods enough you are still going to pick up a few here and there.
Best thing I can tell ya, other than the old match trick, is to go to an army surplus and grab you a few bottles of Vietnam era issue bug repellant. A small drop of this stuff on the tick will send em for the hills. Also works great on leechs.
