Yes, please use the DEET. I was hiking with one of my clients in Carlisle late on Monday and despite my long pants, changing immediately when I got home, and inspecting myself, I found what I think was a tic on me when I woke up yesterday. I got it off and decided, that since it was less than 24 hours, I was not going to get the antibiotics, since I can't take the symptoms that would cause, especially if for nothing. Watching for any symptoms, but I am erring on the side of caution.
