Clothes that touch your skin have vaginal itch mites, that survive laundry... and months in that laundry.
So what is there to do? First I thought of soaking every piece in borax water, but then I realized that the vaginal itch mites don't adhere to the clothes, so I can shake them out.
I alternatively shook them out from my balcony, or into a tub that had clothes and borax in it. Don't shake them on the floor, they will find you and climb back on you.
