Note: some permethrin mixes contain petroleum distillates which may cause skin irritation. As a rule of thumb, the 36.8% variety contains petroleum distillates which strongly binds permethrin to the surface to which it is applied. The 10% variety does not contain petroleum distillates and does not have the same binding quality. For a demonstration of this, check out my video on the subject here: https://youtu.be/vFZzSDqteYE .
