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.

Permethrin SFR 36.8% is not labeled for chiggers and may not provide adequate results for you. Onslaught insecticide is labeled for chiggers and can be used both indoors and outdoors as a broadcast spray. Chiggers are not known to infest structures. Chiggers are most likely outdoors in your yard. Many people are lead to believe that the infestation is indoors because they do not feel the effects of the chigger bites right away and then are lead to believe they are being bitten at a later time. Treatments for chiggers should begin in May and could need to continue through the summer as new chiggers move into the area. Treating the entire lawn is of little benefit because chiggers avoid direct sunlight and normally will not infest areas that are mowed or otherwise well maintained. Focus treatment on the unkempt areas of the lawn and lawn edge. You can also use Onslaught to do a barrier treatment around the outside of your home and in your crawl space to stop pests from moving indoors. If you feel strongly that you are being bitten inside by something we would urge you to get a sample of the pest and have it professionally identified by an entomologist. You can find an entomologist in your area by contacting your local cooperative extension office.
