Q
Can I dilute your permethrin to treat (soak) my clothes like the Sawyer product?
Is there any reason I couldn't buy your 36% permethrin and dilute it to the same .5% that comes in OUtdoor clothing applications for use in treating clothing to repel mosquitos?
A
You cannot use the Permethrin SFR on clothing at all. Even though the products contain the same active ingredients, the formulations are very different and most of our permethrin products contain chemicals that are unsafe to have next to your skin. We do carry Tick Block which is an appropriate formulation for clothing.
