In reply to sheffieldchris:
Blimey, I'd be extremely wary about walking around in a warm humid country with my clothes soaked in a molecule that probably has the ability to penetrate into the skin. I know that DEET, for example, comes out in your urine for 48 hours after you've applied it. In warm humid conditions I expect the skin would be even more absorbant. Have a look at the Safety Data Sheet for permethrin:
