Unfortunately ticks, like mosquitos are a part of life for most of us. Permethrin sprayed on hunting clothes is great, I spray my outer set of pants and shirt the night before a hunt and use deet to repel skeeters and such. I have walked into "nests" of seed ticks before and seen a moving brown mass on my lower pant legs and sprayed permethrin directly onto the pants/brown mass, almost instant stoppage of their movement, from that day on I was a believer. In the late 90's or early 2000's a vaccine called Lyme-rix or something similar came out, I signed up and got the first shot or maybe two shots (can't remember if it was a 3 shot thing like Hepatitis or just a 2 shotter), anyway before I could get the last shot we got a message that said don't do it, no longer authorized, no other information on it. Company said low demand, other scuttlebut said the results could be worse than the tick bite. I pull several ticks a year off of me, seldom after wearing permethin coated clothes during a hunt, usually after a creek fishing trip, or working on the farm etc. I'll never get overly excited about a tick bite, lots of other things more likely to cause my downfall in this life. Besides once you see it, pull it off, seal it up in scotch tape (keeps it from escaping and I hpe causes it a long and suffering death), or give it about a second or two exposed to a cigarette lighter flame and no more worries.
