A few years ago the standard protocol for ticks was a prophylactic dose of doxycycline . It might be a good idea to carry some along with you and take the dose if you find a tick that has been feeding on you. But talk to a doctor knowledgeable about Lyme disease first.
There are other tick borne diseases besides Lyme, so be alert.
Ticks are active at temperatures above 50° F. whatever the season.
