Permethrin SFR is very toxic to bees but will only stick to the surface that it's sprayed on. If the bees don't come in contact with it, it's not effective. If the bees are in the wall void and you're able to spray them directly, it will work but you would have to wear a protective bee suit. Otherwise, we would recommend to hire a professional.
