    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.

    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, they shipped the product as advertised in a very timely manner. I will definitely do business with them again.

    I have bought this product 4 times now over the last 5 years and it works great for my tick problems in my backyard. My treatment is first I use insecticide granules from any store and spread that out first. Then wet it down with the permethrin through my dial and spray attchment for my garden hose. Works wonderfully!

  • 5 of 5 stars  GREAT STUFF!!!
    By Patsie in Kentucky on 03/23/2017

    I live in an area that had an infestation of bedbugs, a few cases of fleas and scabies . I used Permethrin 10% to treat the latter two with great success. I do not want contact a bedbug infestation. So I purchased Permethrin SFR (36.8%) and use as a pesticide control and barrier in my apartment. I spray every 60-90 days. I have NO MORE BUGS and don't anticipate a bedbug problem. I pray.

  • 5 of 5 stars  Best product........Best company
    By Richard in Chandler, Arizona on 03/13/2017

    Moved into mobile home 6 years ago. Lots of German cockroaches, scorpions and crickets. Used to get this at Amazon,but this company is faster and cheaper. In. 4 years have not seen anything inside or out. I spray the bottom 2 feet of outside wall, and 4 feet out of the perimeter. I do it every 90 days. Infestation was so bad, I sprayed inside along the bottomn of wall, and closets. I only spray outside last 4 years, and under the home . Thanks, good luck. In forty years , in Chicago and Phoenix,....this is the best. It came well packaged with no leaks.

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.

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.

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.

QWill Permethrin SFR 36.8% work for chigger control?
We had our home built last year & never had issues except mosquitos. But we dug for a pool this summer & all of a sudden I learned about chiggars. They tore us up so much worse than mosquito bites. I bought the 10% until I could get someone to spray. But now that I'm learning more, I'd like to take care of our issue's. The pool backs up to a small sparsely wooded single line of mainly pines. Just wondering about best mixture & frequency when it starts to get hot again.


Unfortunately, Permethrin SFR 36.8% is not labeled for chiggers. We would recommend Talstar P for that. This would give you lasting control,†has no odor, and dries clear

QIs the combo Permethrin + NyGuard safe in the home for an 11-month old who is crawling?
This combo was applied and we waited the full drying period before returning to the home. There was a strong odor and I am hesitant to allow my child to crawl on the floors. I see posts about the permethin not being safe for even clothing application, so I worry it poses a risk after carpet application. Is there harm in allowing my child to now roam about the house? Why is it dangerous when wet, but safe when dry.


Permethrin SFR 36.8%†cannot be applied to clothing. †Permethrin SFR 36.8%†mixed with Nyguard IGR is safe for children and pets after drying. There is a slight odor, but that dissapates over a short time. In the original wet state, it can irritate skin. That is why we recommend to keep children and pets away until dried. If the treated area were to get wet it does not "reactivate".†

QWhat time of year is appropriate to use Permethrin SFR 36.8%?
Live in Kansas I want to apply product on ground around hive to reduce hive Beetles.


You want to be very careful when using Permethrin SFR 36.8% to treat for hive beetles as the Permethrin is highly toxic to bees! According to the attached article from the University of Arkansas about Managing Small Hive Beetles†:†† Soil Treatment - The pupal stage is a vulnerable time in the beetle life cycle. Slightly moist, loose, sandy soil is optimal for their development. Locating colonies on hard clay or rocky soil, rather than light sandy soil, can reduce the number of beetly larvae that successfully pupate. If larvae are present in the colony,†soil around the hive can be treated with a permethrin drench to prevent the larvae from pupating, killing them in the soil.†

We also suggest that you contact your local Extension office††to see what their recommendations are for as far as time frame for you to do this in your area. Most times they can give you much more precise advice on those times of years more specific to your local area.†

QCan you premix Permethrin SFR and how long does it last?


You should only mix the Permethrin SFR with water when you are ready to apply. Any mixed solution should be dispersed within 24 hours of mixing. Undiluted in the original container (stored away from extreme temps) you will get about a three year shelf life from the date of purchase.
