    Q
    What setting do you recommend for applying this product to my lawn?
    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 be perfect.

    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
    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
    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
    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.

    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
    What does "SFR" mean?
    A
    The SFR has nothing to do with the product itself like most initials after products. It was actually added on by the creater meaning "surfactant for richard".

    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
    Can Permethrin SFR be used as a soil drench to kill ash borers? If so, what is the mixture ratio?
    A
    Permethrin SFR would not be a recommended product as a soil drench for Ash Borers as it is not a systemic and will only kill the insects that contact the treated soil.  Dominion 2L is labeled to use on trees to help protect against boring beetles. Treatments should begin in May or June and should be done every year to protect trees from the Emerald Ash Borers. Most people use a 5 gallon bucket or a large watering can to apply Dominion as a soil drench. You will need 0.1 to 0.2 fl. oz. (3 to 6 mL) of Dominion 2L per inch of trunk diameter for trees. It is recommended that you use the higher rate for boring beetles. The amount of water that is used will vary depending on soil conditions and volumes that are easy for applicators to use. The minimum amount of water that should be used is 1 pint per inch of trunk diameter for trees but you may use 1 quart -1 gallon of water per inch of trunk diameter for trees. Denser soils such as clay do not accept water as readily, so the lower volume of water is suggested.  Since sandy soils can accept more water, using the higher volume of water is preferred. After the soil drench has been applied you should water it in with at east 1/2 inch of water. Note: Water simply acts as a carrier and it is important that even distribution of the product is achieved. Thus, more water may be used if the applicator feels runoff will not occur and proper penetration of the root zone is achieved. Insecticides applied to the soil are taken up by the roots and trans-located throughout the tree or shrub. Root/soil drenches offer the advantage of requiring no special equipment to apply (other than a bucket or watering can). However, surface layers of organic matter, such as mulch or leaf litter, can bind the insecticide and reduce uptake. Before applying drenches, it is important to remove or pull back any mulch or dead leaves so the insecticide solution is poured directly on the mineral soil. It is also important to keep the soil around the tree or shrub moist for the next 10-14 days after applications to encourage uptake.
