Turned black? That ain't normal. Then again, I've never left my permethrin mixture exposed to the air (always inside a spray bottle or garden sprayer), and I always use it up within a week or so.

In the martin bottle the permethrin was ok, sort of yellow color, but after soaking my clothes, the permethrin turned black, maybe the ink of my cloathes, or bugnet ?
Im wondering if the already used permethrin will remain effective if I use it later, 1 or 2 months...
Last year I kept it too in a spay bottle and used it a week or 2 later.
Ahh - probably the ink in the clothes. Polyester doesn't bleed - are these cotton clothes?
In my experience, once mixed with water, the permethrin can lose its effectiveness in as little as three weeks. If you mix it, spray or soak the clothes, then the permethrin dries, you can get a few months out of it.

Yes, going to a 3 days canoe-camping this week, going to take it relax on the camp so yes, I treated some coton t-shirts.
My martin's permethrin bottle is empty so I guess I have to get a new one if I want to threat my clothes again in a 5 or 6 weeks.
Maybe it will last but I prefer to treat it again, im a real mosquitoes magnet
While looking for support for the 40% (which is very high compared to the Saywer spray) I found this page: https://phc.amedd.army.mil/topics/en...nt-System.aspx
which talks about the DoD Insect Repellent System. My favorite line is "The DoD insect repellent system is used against arthropods of military significance."
For people worried about Permethrin, they say:
- There are no know adverse health risk associated with wearing the OCP Permethrin treated uniform.
- Safety testing of permethrin has been conducted almost continuously since the 1970's, following its Environmental Protection Agency (EPA) registration for use with a variety of applications including food/feed crops, livestock, Public Health mosquito abatement programs, pets, and clothing.
