    ... hmmmm

    By J on 12/25/2015

    Verified Purchase

    My dog had ticks, so I mixed and sprayed per instructions mixed at 1/4 fl.oz per pint ... didn't do squat, so I decided to test on live ticks, and was able to verify out of 10 ticks 9 survived for more than 1 hour at the the rated concentration. Increased the dosage and tested again with double , but it did not kill all 10 ticks until I mixed 5/8 fl.oz to each pint. Maybe I got a bad batch, but I am going back to Talstar

    Please note that Permethrin is not a contact kill product. It can take 24-48 hours to kill in an insect after they have received a lethal dose of the product.

    Not effective as it used to be

    By Timothy on 07/09/2015

    Bought same product 4 years ago and this one is not nearly as strong as it was

    Expert Response  Expert response:
    Thank you for your review. We can tell you that the manufacturer h not changed their formula or the concentration of the Permethrin SFR. Some pests are able to build up a resistance to certain insecticides after repeated exposure over generations and that is possibly the case here. Please call us at 866-581-7378 so we can help you put together a more effective treatment program for your needs.

    Not happy

    By Stacey on 08/22/2017

    I give two stars only because of how easy it was to order and how fast it came. I was not happy with this product because it kept bugs away for 24 hours then all mosquitoes, spiders, ants and more were back with a vengeance. The mixing of this product was frustrating as well. I figured it out but it could have been written in a simpler way.

    Not as potent

    By Richard on 08/06/2020

    I have used other products in the past with very good results. This product mixed to proper specs does not appear to be as potent. Flies came back in hours instead of days. The 36% concentration performs like a 13%.
