Panty hose are good for only a few days and are pretty hard to rinse out. Also, they catch small stuff like insects, but you will find that the really small stuff like dust gets through. When I finally got some proper socks, they were not too expensive--a dollar or two apiece. They last quite a long time, they fit like they're supposed to, without slipping, and you'd be surprised at how much they catch. They also rinse clean with a quick spray from the hose. I'm planning on buying another year's supply when I get back to the mainland.
