My over half-a-dozen pairs-of-socks, used to lazing around and stinking real bad, got a prolonged bubble bath in soapy water. I soaked them at around 7 am and hoped to wash them when I came back from office. When I was finally back, the tap, as usual, was dry. So they remained in the bucket, water blissfully permeating through their fabric.
I've a hunch stinking socks are a natural mosquito repellent.
