    5 of 5 stars  Flea infestation
    By Mark in Ft Worth, Tx on 05/18/2012
    Verified Purchase

    Had a major flea infestation, probably wasted 2 weeks trying to get control of the problem with store products, don't waste your time with local store killers. Found do my own pest control, purchased permethrin and an igr and immediately got control of the situation. With a major infestation, don't be surprised if you have to make several applications over a 2 week period and thats due to the flea life cycle, but this stuff is the best and a local exterminator agreed.

    5 of 5 stars  Japanese Beetles
    By Hildegard in Saint Peters, MO on 07/16/2010

    My yard had literally thousand of beetles this year. In my 50 years of gardening I never encountered any until last year. They loved the Crepe Myrtles, Virginia creeper, Pussy Willow, blooms on the Oak Hydrangea, and I even had them on the Echinacea petals and inside the Day lily blossoms. Permethrin SFR, just 10 cc per gallon of water had them eliminated within 2 days.  There are just a few stragglers now and in the last few days. Doing it myself saved me much money, thank you for making it available to the private consumer.  Directions must be followed to avoid damage to plants and/or pets. I had no unwanted results this way.

    5 of 5 stars  Great Value---Quick Shipping
    By Jason in Miami, FL on 09/12/2011
    Verified Purchase

    Bought for a tick infestation in Miami, Florida. Product is highly concentrated, so it's very economical for use with a hose sprayer for treating lawn. Seemed to be effective, particularly when combined with Preventic collars on the dogs. Ordering was easy and they shipped very quickly.

    5 of 5 stars  Great Product
    By Daniel in Deer Park, TX on 09/26/2010

    I ordered the Permethrin after a little online research. It worked very well. I have no signs of fire ants all along my fence line or any more of those crazy Rasberry Ants either.....all after one application. As for domyownpestcontrol.com, they shipped the product as advertised in a very timely manner. I will definitely do business with them again.

    5 of 5 stars  Ticks and Fleas
    By Aleon in Mcallen, TX on 04/21/2013
    Verified Purchase

    Gets the job done. I started using this last year for ticks and fleas indoors and out. Used about 1oz to 5 gals-water mix for the yard and after four applications (just finished one bottle) using a "end hose sprayer" the ticks were gone and did not come back this year. Fleas are back, but I probably will have to spray every few weeks to get rid of them again which is expected as I have alley cats and dogs all around. I also dip my huskey with this after a regular bath using the same concentration and she's been real clean and happy since I started with this last year.

    By Donald in Exeter, maine on 08/08/2017

    For four years, no matter what product I used, Japanese beetles ruled the day. This is the ONLY product that works. They will be dead withing 5-10 minutes of application. AND, others will not come back. At 36.8 %, this is the High Test, diluted of course. Thank you, saved my gardens and my sanity.

    5 of 5 stars  sod webworms
    By Joe in Florida on 08/06/2017

    Had a huge infestation of sod webworms in my St. Augustine lawn. Had several lawn companies treat the grass, however, the problem continued. Purchased Permethrin SFR 36.8, several years ago, and I apply it in early spring and in the summer to kill their life cycle. The product is the only thing that I have found that kills sod webworms.

    Does the job. Got rid of pests. Will redo every thirty to 40 days. Easy to mix with 2 oz pre-measure cup. No surprises, read about and watched informative video about product and all was explained well. Label: How to mix is easy to understand the different mixes for what your purpose and application might be.

QWill Permethrin SFR kill black widow and brown recluse spiders? Is it safe for gardens, children, and pets?
will permethrin sfr get rid of black widows and brown widows or is there a better product for these spiders? Please tell me the dangers for small children, animals and an organic garden. Thank you

ABrown recluse spiders and black widow spiders share the same biology as every other species of spiders and are not any harder to kill than other spiders. Permethrin SFR is labeled for spiders and should do a great job in helping you eliminate spiders in and around your home. Permethrin SFR is safe around children and pets as long as they are kept out of the area during the application and they do not return to the area until it is dry. Permethrin SFR should not be used in an organic garden because it is a synthetic product and it is not labeled for use on most types of edible plants.

QCan I use Permethrin SFR on my dog? If so, how much product should I use per gallon of water?
I just got a 3 yr old pit bull and he has lots of ticks.

AYes, you can use Permethrin SFR on your dog. You should use ¼ fl. oz of product to 1¼ gallons water then thoroughly wet the animal to the skin with sponge or rag. Let drip dry. You can find these instructions on page 16 of the Permethrin SFR product label which we have linked in this answer for your convenience but is always available on the Permrthrin SFR product page.

QUsing Permethrin SFR how many oz per quart water for mix of .5%?

AYou will need to use 1 2/3 fl. oz. for each gallon of water to get a 0.5% ratio. If you only need to mix one quart of solution at a time you will need to use just under 1/2 (0.43) oz of Permethrin SFR per quart of water to get a 0.5% mixture.

QHow often should I treat with Permethrin SFR 36.85% for fleas and german roaches?
My yard and house have fleas and german roaches. After the first treatment how long until I should treat again?

A

Permethring SFR 36.8% gives you up to a 30 day residual outdoors, and up to a 90 day residual indoors. We would also recommend using an Insect Growth Regulator (IGR) as well for both these pest applications, such as Nyguard IGR Concentrate. This will help stop the reproductive cycle in both the roaches and fleas.

QWill Permethrin SFR 36.8% be effective next spring for Browntail moth control?
We live in coastal Maine and have lots of Browntail moth caterpillar webs high up in our oak trees. Is this product recommended for this use?

A

Permethrin SFR 36.8% can be effective against Browntail Moths but direct contact must be made to increase the effectiveness. Pesticides should be applied when caterpillars are small and feeding, usually before the end of May.

Control of browntail moth populations in isolated areas may be obtained by clipping the overwintering webs and destroying these webs by either soaking in soapy water or burning them, according to the law ordinances in your county. This control should be undertaken in the winter and very early spring. For more information you can contact your local cooperative extension office.

QWhy wouldn't Permethrin SFR 36 be a good option for mosquito control, and can it be used in a hand held fogger?

A

Permethrin SFR 36.8% is not labeled to be used for mosquitos in yards and cannot be used in a fogger.  Fogging is really only going to kill those that are out in the area at the time of application and may make the area slightly repellent for about a day or so.  Talstar P 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.
