Since Permethrin SFR is an oil-based product it is going to be more prone to break down in the extreme heat and sunlight in your area faster than other products. You will likely have to reapply the Permethrin every 30 days to keep insect populations under control and have a strong residual still on the surface. We would suggest when you get ready to order more product in the future going with something better designed for your environment like Cy Kick CS or Onslaught FastCap which will also likely give a better control over arachnids and other pests they feed on due to their encapsulation.

Permethrin SFR 36.8% is not labeled for chiggers. 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.
