These products should not be mixed together. There is no valid reason to mix Onslaught and Permethrin SFR together. They are both synthetic pyrethroids so there would be nothing to gain by mixing these products together. Making a pesticide too strong can actually backfire. Areas that are treated with this overly concentrated spray will be repellent and insects will simply avoid the treated areas prolonging the infestation.
Permethrin SFR is labeled for scorpions and you would use at a rate of 1 2/3 fl oz to 3 1/3 fl oz per gallon as directed on the product label.
Permethrin SFR is not labeled for use on clothing and is not formulated for such a use. We do carry a permethrin-based product called JT Eaton KILLS Bedbugs, Ticks, and Mosquitoes that is labeled for use on clothing. It comes in a ready-to-use spray bottles and does not need to be diluted.
We do not recommend using Permethrin SFR in a fogger. The actual product label does have recommendations for using it in a fogger indoors, but only in very limited situations. We do carry concentrates that can be applied using a ULV fogger and thermal fogger.
For carpenter ants, you will mix 1 2/3 oz of Permethrin SFR per gallon of water. We do suggest that you check out our carpenter ant control products to achieve the most effective results. The treatment article below will also offer helpful information for eradication and prevention.
Depending on the mix ratio used and how heavily you sprayed, it could be anywhere from just as the product has has had time to dry, or several hours after application before the smell of the Permethrin SFR completely goes away. If the odor is objectionable, then you may want to consider switching to a water-based insecticide, rather than an oil-based one.

Permethrin SFR 36.8% can be used on livestock only to help control scabies mites. It cannot be used on humans or in residential areas to control scabies mites. Please consult the product label for specific instructions.
Because Permethrin SFR is not labeled for use on clothing or other items that would contact skin, we are not able to give an exact recommendation as to how many washings would deem the fabrics safe for wear, if at all. A small amount of product could be washed, however, something like full strength product would persist longer, and we would not recommend wearing clothing that had significant chemical residue on it.
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.
Permethrin SFR needs to be down for at least 6 hours prior to rain for it to be rainfast.
