I'm so sorry that you got bitten again. I can relate to wanting to be out in the yard. If you wear clothing that is sprayed with Permethrin, (I use Sawyers from Cabelas) the little blood suckers curl up and die. We spray our shoes, socks, pants, shirts and hats that we use just for outside work. There was a study done that shows that ticks can live through a washing machine cycle, but not through a dryer cycle, so it might be better to throw your clothes in the dryer first, then wash them.
Take Care,
Karen
