    Q
    Permethrin SFR 36.8% kill Chiggers?
    A
    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.

    Q
    Can I use Permethrin SFR to treat ants in the lawn? How do I apply it?
    A

    Yes, you can use Permethrin SFR to control ants in the lawn.  You will mix 0.4 to 0.8 fluid ounce 4 to 25 gallons of water per 1,000 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.

  • Asked by Sam from Florida
    04/03/2019
    Q
    What class is Permethrin? Can I use this as a Talstar resistance alternate?
    I do not want to use only one insecticide all season for control of chinch bug and sod web worm (Talstar). Bifenthrin appears to be losing effectiveness on these insects, is Permethrin the same class as Talstar?
    A

    Permethrin SFR 36.8% is a synthetic pyrethrin like bifenthrin so they would work comparably.  Dominion 2L would be a good option to use for chinch bug control and is a neonicotinoid and systemic so is absorbed by the roots that these bugs feed on.  Best applied before they are active so it has time to be absorbed.

  • Asked by Phil from Cascade, Id
    09/12/2014
    Q
    Utilizing Dominion 2L for pine borers via soil injection. When should applications be made.
    A
    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. Healthy trees can be protected before the beetles attack by topically spraying them with a synthetic pyrethroid like Permethrin SFR.  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.  The tree should be sprayed from the ground to 15 ft up the trunk to prevent future infestations. You should contact your local cooperative extension office to find out the best time to start spraying in your region.

    Q
    What Is The Expected Wait Time Before Permethrin Kills Fleas?
    I have applied Permethrin SFR as a broadcast spray inside my home, also mixed with Archer IGR, both per their respective manufacturer's instructions. The solution was sprayed due to a flea infestation that occurred while I was away for business (it is also a 100+ yr old farm house so very susceptible to bugs etc). Are the affects to be expected immediately or after a delay? I have had great success with previous purchases from you guys and have faith this will be the same, just not sure how long I have to wait. Many thanks for your help.
    A
    Depending on many factors such as insect type, etc  Permethrin SFR 36.8% can take minutes to hours to kill insects. Permethrin SFR is not labeled to be applied as a broadcast inside. You would want to use Archer mixed with a product like Onslaught labeled for broadcast. Please keep in mind that it can take at least 2 treatments to eradicate fleas. Be sure to keep up with the vacuuming too.

    Permethrin SFR 36.8% can be applied to ornamental plants and trees to treat lacebug at a rate of 0.9-1.8 oz per 10,000 sq ft or 4-8 oz per 100 gallons of water.

  • Asked by Allan from Canada
    04/01/2018
    Q
    When used as a surface spray on exteriors of buildings, how successful is Permethrin SFR 36.8% against mosquitoes?
    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.  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 36.8 kill wireworms and click beetle adults?
    I have found click beetles and the wireworms in my garden around hostas and other plants. Will this product take care of them? How deep in soil does it need to get? Should I also use a granular too? If yes, which one would be best? Thanks
    A

    Permethrin SFR 36.8%  will not treat for Click beetles/Wire worms. It is hard to find a treatment that is labeled for these pests. First, be sure to remove or clean up any piles of debris in the yard or patio/deck. Research shows that cutworm treatments have proven effective on Click beetles.We would recommend Cyonara RTS.  It comes in a convenient bottle that hooks up to your hose and is labeled to apply in your garden.  It will not only take care of cutworms, but many other pests that might be in your garden.

    Q
    Will a surfactant increase the effectiveness of Permethrin SFR 36.8%?
    I recently bought Permethrin SFR for various ants and it is working. Since the most recent rain we have had fire ants pop up everywhere and so I was wondering if a surfactant would make SFR even more effective. I am pleased so far with the results, just want even more fire power if possible. Also sometimes it rains soon after I spray so maybe it would stick better with a surfactant.
    A

    Yes, a surfactant can be used with Permethrin SFR 36.8% to help it stick better and increase effectiveness.  Hi-Yield Spreader Sticker would be a good choice.  You can find our other surfactants here as well.

    Q
    Can I mix Permethrin SFR 36.8% (about 8 months old) and 10% together?
    I have two bottles...one is SFR 36.8 and other one is 10% (about 3 years old). Can I mix them together in an empty dried drinking water jug - gallon size?
    A
    It is not recommended to mix Permethrin 36.8% and Permethrin 10% together in a water jug for storage. They should remain in their original containers at room temperature. They have a 3 year shelf life from the date of purchase if stored away from extreme temperatures.

    Q
    How effective is this for bed bugs?
    A
    Permethrin SFR is labeled for bedbugs but you will need to use other products in conjunction with the Permethrin SFR to eliminate a bedbug infestation.

These bedbug proof covers will trap existing bedbugs and eliminate hiding places and make inspections easier.Please take a few moments to read our BEDBUG GUIDE to learn more about eliminating bedbugs.
