Permethrin SFR 36.8% - Questions & Answers

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. 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.

According to the Permethrin SFR 36.8% product label, you may spray 4 fl oz to 10 gallons of water.  For severe infestation, it is permissible to use 4 fl oz to 4 gallons.

Yes, Permethrin SFR 36.8% can be used for carpet beetle larvae. You will need to use 1 2/3 fl. oz. for each gallon of water to get a 0.5% ratio. When using this product for carpet beetles the label states to apply the spray evenly to rugs, carpets, along baseboards and edges of carpeting, under carpeting, rugs and furniture, in closets, on shelving, and wherever else these insects are seen or suspected. For the best control of immature stages, we recommend adding an IGR (Insect Growth Regulator) to your insecticide, such as NyGuard EZ1.

For flea control, we recommend retreatment with insecticides such as Permethrin SFR every 14 days until you have no more signs of fleas. Most successful flea treatment programs require at least 2-3 treatments at 14-day intervals using both an insecticide for the adult fleas and an Insect Growth Regulator (IGR) to prevent immature stages of fleas from developing into breeding adults. You will not be able to make just one insecticide application for fleas and never see them again, especially if you did not use an IGR in your treatment. Fleas multiply very quickly, and they have an immature stage that is protected from insecticide, so new fleas will continue to emerge after you have treated. Be sure, also, that you are vacuuming every day or every other day to help pick up adult fleas, flea dirt, and eggs, and also to stimulate those immature fleas so the adults will emerge and be exposed to the insecticide you have put down. We have more tips and details in our Flea Treatment Guide here.

Healthy trees can be protected before the beetles attack by topically spraying them with a product called Permethrin SFR. The tree should be sprayed from the ground to 15 ft up the trunk to prevent future infestations.  Unfortunately, there is no easy solution when it comes to pine beetles. Infected trees should be cut down (before the newly hatched beetles fly out of the trees in the spring/summer) and the wood burned or chipped, while other still healthy trees should be sprayed annually to protect them. Because of the natural boring behavior of the beetle they are protected from topically applied insecticides and systemic insecticides (those injected into the tree or applied as a root drench) have proven ineffective for pine beetle infestations.

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.

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.
