I know that Permethrin is highly toxic to fish but clothing that could get wet with <=2 ounces of a water-based 0.5% concentration applied that actually binds to the fabric when dry would not be toxic to fish in a stream or lake.
I went through several bottles of the Sawyer 0.5% concentrate spray treating my trousers, shirts, and socks and hammock, then letting it dry for at least a day and found combining it with Picaridin on exposed skin was highly effective at keeping mosquitos, ticks, and other biting bugs off me in boggy high meadow areas right after melt-off even while wearing shorts when other people with untreated clothing were covering themselves head to toe and being driven out. But a 24 oz bottle of Sawyer spray costs almost $4 to treat one set of clothing; trousers, shirt, & socks, and double to triple that for my hammock.
To save money I tried using a petroleum distillates based 10% Permethrin concentrate diluted 20:1 with water for a 0.5% mix on my clothing. But after letting it dry thoroughly for days it still had a strong odor and I had a reaction of nausea and vomiting. Then I found an odorless water-based (the label does not state that it contains petroleum distillates) concentrate and used it for years in a 0.5 mix without a problem. The cost to make a 20 oz bottle to treat 4 sets of clothing was less than $1.
Last week I tried to order some more. The order was cancelled because it's toxic to bees so WAC 16-230-082 places restrictions on permethrin used near pollen shedding corn in Yakima, Franklin, Adams, and Grant counties. The result is the distributor will not ship the water-based concentrate to anywhere in WA. However I live on the west side where the 10% petroleum-based concentrate is widely available in stores???
Has anyone used the petroleum based Permethrin concentrate, had a reaction, and later found a way to to use it without a problem, perhaps like washing the clothes first?
