    ACTUALLY WORKS

    By mehrylie on Nov 29, 2020

    I have tried four different flea sprays before a friend recommended this one to me. We struggled with fleas for MONTHS. After so much guilt for my pets suffering, we tried this as a last ditch effort before we called in an exterminator. Worked after just ONE use. Took my pets to a friends for the weekend I have tried four different flea sprays before a friend recommended this one to me. We struggled with fleas for MONTHS. After so much guilt for my pets suffering, we tried this as a last ditch effort before we called in an exterminator. Worked after just ONE use. Took my pets to a friends for the weekend, sprayed half the bottle around the whole house, vacuumed, and we have never needed to spray again. HIGHLY RECOMMEND. You need this. … more

    Didn't hold its end of the bargin

    By AussieOwner on Oct 12, 2020

    Verbal did kill the adult fleas but 2 weeks later my house was infested again. The claim that it will last for months did not hold up.

    Not as effective as we had hoped

    By on

    This killed the initial round of fleas, but it has not kept killing them as stated. We have fleas again despite all pets being on preventative and regular vacuuming. This spray is too expensive to not work well!

    Knockout ES

    By on

    It seemed to really kill the fleas for two days. Then they slowly started to show up again the third day. I used it on the carpet and furniture, vacuumed the furniture and carpets. I ordered two cans just for follow up if needed and it was needed. The fleas aren't as bad but I hoped they would be dead, but they aren't.

    Did not work in an infestation for us

    By on

    We tried this. It worked short term then the eggs hatched, go figure. We had quite the infestation and didn't realize at the time, it does work though.

    Kills but doesn't treat the amount stated

    By on

    Bought some of this from my vet and I thought one can would work because my house is less than 1000 square feet. I followed the directions it sprayed very little and foamed everywhere. It only treated my tiny living room! How am I supposed to get rid of fleas in the rest of my house if it only treats a tiny 100 square foot area? So much for getting rid of fleas.

    Coverage is questionable / Pricey for what you get

    By on

    Says approximately 2,000 square feet, followed the directions, but it ran out very quickly in a 1400 sq ft home with mainly wood floors that did not get treated. Although the flea problem is minimal now, we still are battling the problem.

    helped somewhat

    By on

    We have a large basement with a flea infested cat. Since the cat is semi-feral and can't be caught I have not been able to treat the cat. I have done a lot of cleaning and have sprayed twice, but there are still fleas. I can't fault the spray . The order was received quickly and I would order again from chewy as the price was very good.

    Not That Great

    By on

    This product is supposed to cover 2100 sq. ft. I have used 4 cans of this stuff in my 2000 sq. ft. home and, three weeks later, I am still finding fleas on my indoor-only kittens. I used the products on all carpets, rugs, draperies and furniture.
