Bill,
My job and hobbies keep me outside basicly 365 days out of the year, my associates much the same. One associate got R.M.S. Fever, it almost killed him. I've been thru the treatment for Lymes disease and the strong antibiotics after a few days gave me the "screaming willies", it was no fun knowing what was coming for the several days ahead.
I said all that to say this, get you some Permethrin spray! Read the directions and follow. This stuff does not break me out with skin contact, one son gets hives all over with skin contact (Before it dries on clothing). This is the only thing that will keep ticks off you. 100% deet works fairly well but Nothing like Permethrin, plus once your clothes are treated, it lasts thru a wash or two. However I always sparingly reapply every outting.
Hope this helps!
