any particular brand??
No need to get freaked out over the possibilities. I could get struck by lightening with approx the same frequency.
Sawyer's permethrin (yellow box) will do the trick--do not apply directly to the skin. Downeast Maine where I live is ground zero for one of the highest new Lyme contraction rates per capita in the US--I've hunted heavy brush infested with deer ticks (the primary Lyme carriers up here) with clothes treated with permethrin and couldn't find a single tick on me afterwards. It works. The only other thing I would add is if you get any kind of bite that is persistent and itchy (and you're not sure what bit you)--like a hard mosquito bite might feel like--AUTOMATICALLY assume exposure and seek preemptive treatment IMMEDIATELY. A low dose quick treatment of antibiotics has a near 100% probability of preventing the disease with little to no risk. All the other crap about "waiting around for signs or sending ticks out for tests" is wasting precious time allowing the disease bacteria to establish a beachhead in your body's tissues. Any medical person that advises you otherwise is not Lyme literate--and you should move on and find one that is.Thousands of Eskimos are laughing right now at how foolish it is to take tick precautions.
For the rest of us, if you have ticks, you can get Lyme and the odds are getting better every day. For you guys who already know it all, isn't spring suppose to be your busy time? Don't waste it here.
Treat your cloths with permethrin and cut the odds down down down. It is cheap, easy, and you need this stuff around the house for just about every other insect problem you have. Get the high concentrate and mix it down to suit the use.
