Does Permethrin SFR 36.8% kill chiggers in the house?

I have chiggers all in my house and clothes. I have used everything possible, but I need something that works.


Permethrin SFR 36.8% is not labeled for chiggers.  Onslaught 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. 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.
