    Q
    Can Permethrin be used in a hose end liquid sprayer?
    how much would the dilution be for general lawn spraying for fleas, ticks and ants in an area dogs will be
    A
    You can use PErmethrin SFR in a hose end sprayer as long as it can be calibrated to the required usage rate. According to the Permethrin SFR product label:  For fleas, ant and ticks in lawns - 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.

    Q
    I have a small grass area that I have seen small cockroaches in at night. I would like to use Permethrin to
    get rid of the pest. I have small dogs that will be playing on the grass and at times will eat the grass. If I use Permethrin, will it be safe for the dogs and how do I apply it?
    A
    According to the Permethrin SFR product label you will need to use about 1 2/3 fl oz per gallon of water for each 1,000 sq ft area. You will need to keep your dog out of the area during the application and the dog can return to the area after it has dried. There will only be very small diluted deposits of the insecticide on your lawn and the small amount that you pet may ingest should not have any effect.

    Q
    Will Cyfluthrin kill the sarcoptic mange mites inside and outside of the house?
    I must find the source of the sarcoptic mites and kill them.
    A
    There are very few products that have sarcoptic mites or scabies mites listed on their product labels. You didn't mention if the mites are a problem on people or on animals, but the environmental treatment is pretty much the same. Wash and dry (high heat) all bedding and thoroughly vacuum all resting areas. Indoors you can use a product called Steri-Fab on all upholstered furniture, rugs and pet beds and resting areas. Outdoors you can use a product called Permethrin SFR on pet resting areas and other areas frequented by your pet. In most cases, it is not necessary to treat the outdoor environment unless it is frequented by animals such as stray dogs or foxes because sarcoptic mites cannot live very long off of the host animal (usually not more than 72 hours).

    Q
    How many square feet does a 1.25 gallon of Permethrin SFR 36.8% cover outside?
    A

    The amount of area that a gallon of Permethrin SFR 36.8% treats will depend on what you are treating for. If you are using this for general use, you will use 1 2/3 fl. oz. per gallon of water. This will make approximately 99 gallons of solution and will cover 99,000 square feet. This is over two acres.

    Q
    What does SFR stand for?
    I bought Permethrin SFR and have been using it to treat my outdoor work clothes. You have stated elsewhere that this product is not labeled for use on clothing, but I see products on Amazon (such as Sawyers) that use permethrin for this purpose so I wondered if the SFR designation relates to the use. Also you state that permethrin is not listed for chiggers but that is the main reason I am treating my clothing and was under the impression that it is effective against chiggers.
    A
    Permethrin SFR is a different formulation than the products that are labeled for use on clothing and it should not be used to treat clothing under any circumstances. Permethrin SFR is not labeled for chiggers which is why we do not recommend it for chiggers. Manufacturers do a lot of research and testing before they are allowed to add an insect to their label. In this case the manufacturer may have felt that the product was not effective enough on chiggers to add the insect to the label or that chiggers were not a significant enough of a pest to do the research and testing on so didn't even try to add it to the label. SFR stands for Surfactant for Richard. Apparently Richard was one of the staff members who helped formulate the product and the suffix stuck.

    Q
    Can you use Permethrin SFR to kill wasps?
    A

    You can use Permethrin SFR, but it will NOT kill wasps on contact.  The wasps/bees will die, but not immediately.  It can take a few minutes for them to succumb to the product.  Permethrin will help to deter them from nesting in areas it has been sprayed.  Wasp Freeze is your best choice if you are looking to knock down wasps instantly.

    Q
    Is Permethrin SFR 36.8% a good product for exterior perimeter control of roaches?
    We have previously used a spray product called Bengal which lists permethrin as its main ingredient and it does a great job, but we are looking for a product to mix and spray the perimeter of buildings.
    A
    Permethrin SFR is labeled for roaches and is widely used by professionals for this purpose both indoors and outdoors. Be sure to read and follow the Permethrin product label for the best results.

    Q
    Can we use Permethrin SFR 36.8% for deer flies that bite?
    We are having a problem with biting deer flies,and my son is very sensitive to their bites. He gets a huge welt and swelling. Is there also a cream with permethrin in it?
    A
    No. Permethrin SFR 36.8% cannot be used on your body. We only carry products that can be used on/in your home or yard. Permethrin SFR 36.8% will help control most insects that land on areas that have been sprayed such as your bushes, or lawn.

    Q
    What is the recommended concentration for general tick control?
    The label is VERY vague "Mix 0.4 – 0.8 fl. oz. of Permethrin SFR in 4 to 25 gallons of water per 1000 square feet". That a range of 1:12.5 or concentration of ~.005% to ~.06%. Yet your web discription says "1 QT yields 20-40 gallons of finished solution". That's a concentration of ~.48% to ~.23%. There's something wrong here. I suspect a .5% solution is probably correct but how much of that should I apply to 1000 sq ft of lawn?
    A
    Product labels are indeed vague in many cases as this gives the applicator leeway to use different concentrations for different situations. You should use the higher usage rate for heavy infestations, faster knockdowns and longer lasting residuals and lower usage rates for maintenance sprays. You will need to use higher volumes of water to get the product over thick, dense vegetation. If you are treating your lawn for ticks we recommend you use the higher specified usage rate of 0.8 fl oz Permethrin SFR for 1,000 sq ft using whatever volume of water is needed. If you are treating up close to your home you are permitted to use the .5% emulsion (1 2/3 fl. oz. per gallon of water) per 1,000 sq ft as a perimeter treatment.

    Q
    What is the setting for Permethrin SFR 36.8% in Ortho Dial-N-Spray Hose Sprayer?
    I'm looking to treat my yard with Permethrin 36.8. I'm trying to figure out what dial indication on my hose end sprayer I should be using for my yard treatment per gallon. I have dials such as 1 oz, 1-1/2 oz, 2 oz, etc. and all the way up to 8 oz. What are your recommendations? This will primarily be used for treating for ticks and mosquitoes.
    A

    The mixing ratio for Permethrin SFR 36.8% on lawns is anywhere between 0.4 oz up to 0.8 oz per 1000 square feet or per gallon of water. A dial setting at half of an ounce per gallon on the hose end sprayer would work for most sprayers, but we would recommend to calibrate your equipment with just water before applying your insecticide to make sure you are not using too little or too much insecticide for the area.

    Permethrin SFR is only labeled for mosquito control on livestock premises. A better product for mosquito control outdoors is Talstar P. Talstar P is gentle on vegetation where you will be spraying for mosquitoes and it will last up to one month for mosquito control. When using Talstar for mosquito control, you will use 1 oz of product per gallon of water. Talstar P can also be used for tick control, if you would like to use only one product for your needs.

    Q
    I live in Michigan with a yard that backs up to the woods. I have a big problem with mosquitoes.
    Any suggestions? I am currently using Permethrin SFR.
    A
    Is the Permethrin SFR working well?  If so, we always recommend to stick with what works.  Once downside to Permethrin SFR is that it usually does not last very long outside, usually only a week or two.  We do have a product called Talstar, which is our most popular product for flea control and it will last for 30 days before needing to be reapplied.
