I purchased a spray-bottle of Sawyer 0.5% permethrin to treat some of my clothing in preparation for a backpacking trip. The spray nozzle turns out to have been quite a bit more generous than I anticipated - a fact that I realized only after using roughly twice the recommended amount on my first outfit. In all other respects I have followed the directions on the packaging to the letter.
Is the overtreated outfit unsafe to wear? Would it be an overreaction to wash it once the treatment dries?
EDIT Just returned from our trip. Wore the aforementioned outfit without washing for a couple days on the trails. 100% anecdotal, but no tick bites, few mosquito bites, and most importantly none of the adverse symptoms associated with permethrin.
Great weather, too!
