    Q
    How much Permethrin SFR 36.8% should I use to kill mosquitoes in my yard?
    A

    Permethrin SFR is only labeled for mosquito control on livestock premises. A better product for mosquito control outdoors is Talstar P and it can be IGR such as Tekko Pro to help sterilize the adults. It is our most popular product for mosquito control and would be a better option. It is a liquid concentrate that you mix with water and apply using any hand pump sprayer or backpack sprayer. You will mix 1 fl oz of Talstar and 1 fl oz of Tekko Pro per gallon of water. The key is to apply it to all shrubs, trees, and other foliage around the house or patio where you are trying to provide relief. It should be directed not only on top of the leaves and plants but on the underside of the leaves as well, which is where the mosquitoes like to hang out.  It should be applied every 30 days for optimum control.

    Q
    Will Permethrin SFR be effective if used as a spray above a drop-ceiling for varied carpet beetles?
    A

    Since Permethrin SFR is labeled for use indoors as a crack and crevice spray, you could potentially use it as part of a carpet beetle treatment program. We recommend adding an Insect Growth Regulator (IGR) when treating for carpet beetles, such as NyGuard IGR. You could also use a ready-to-use product like NyGuard Plus which has both an insecticide and an IGR in one product. A better choice for use in the drop ceiling may be an insecticide dust, though, since it is a dry product that would not damage the tiles, and a dust lasts much longer than a spray in void spaces like a drop ceiling. Delta Dust can be used in a drop ceiling for carpet beetles and other crawling insect pests there. Or you may consider our Carpet Beetle Control Kit which includes the NyGuard Plus, CimeXa Dust, and glue traps.

    Be sure that you have located and removed the source of the infestation as well. We have more tips in our Carpet Beetle Treatment Guide here

    Q
    Can Permethrin SFR be sprayed on the ground and shrubs to control ticks?
    A

    Permethrin SFR 36.8% would be a very effective insecticide to control ticks.  It is labeled for ticks (including Deer Tick and Western Black legged Tick).  Permethrin would be mixed at 0.4 to 0.8 Fluid Ounces per gallon of water to treat 1000 square feet of lawn and applied as a broadcast application. 

    It would also be a good idea to incorporate an insect growth regulator (IGR) such as Archer IGR for complete control of ticks.  All of these products are pet safe if used as directed.  Pets need to be kept out of the area being treated during application and until everything is completely dry. 

    Please look over our Tick Control Guide for more information on treating and preventing this pest.

  • Asked by William from Franklin

    Q
    Will Permethrin SFR 36.8% kill chiggers?
    A

    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.

    Q
    Can I use Permethrin SFR for sod webworms? How is it applied?
    A

    With Permethrin SFR 36.8% for sod webworms you will mix 0.4 – 0.8 fl. oz. of Permethrin SFR in 4 to 25 gallons of water per 1000 square feet. Use the higher rate for fast knockdown and increased residual control. Dense or excessive (greater than 3 inches) lawn height and arid conditions may require higher volume application rates. Repeat application if necessary. Application in combination with compatible surfactants or wetting agents may enhance penetration.

    You want to make sure you are using enough water to get it down to where they are better so 1 gallon is usually not enough.

  • Asked by Frank from Long Beach, Ca
    11/16/2019
    Q
    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.
    A

    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.
