Looks like you got all your questions pretty well answered. Most permithern says its lasts on your clothes around 6 weeks, so I usually treat 2 shirts and 2 pairs of pants mid September right before the opener and wear those until mid to late October when the frosts hits. By that time you won't really need to reapply it in my experience. I also treat my rubber boots and always tuck my pants into the boots and tuck shirt into pants. ticks always work their way upward. so if your pants aint tucked in, they go right up your leg and end up in your no no special spot. Best day 0f the year every year is first frost. no mosquitoes, flies, ticks, chiggers. just awesome. good luck this year.
