    I ended up calling the vet about my infestation of fleas. I really never thought I would have to worry about it with my indoor cat. Unfortunately, my college age daughter worked in a thrift shop over the summer and brought fleas home. What a great gift! My poor cat was a mess. We tried all the environmentally safe stuff first and nothing was working so I finally called the vet, she recommended Knockout. I will say that I was worried about all the warnings that come with each can of spray, but really liked the effectiveness of the product. I have a small two bedroom apartment and one can was enough to cover almost all of my furniture and area rugs. I did buy another can as well to cover my sectional I ended up calling the vet about my infestation of fleas. I really never thought I would have to worry about it with my indoor cat.

I live with a gas stove so I can't bomb the place and this method worked well for me. It is a regiment of products to get rid of the fleas, including; flea shampoo, a topical product like Frontline, and Knockout spray. I am only on the first month of this battle, but have seen a marked decrease in the number and size of the fleas I find on my cat. Each combing there are less and less. Today I found none, Yahoooo! … more

  • It works!!!

    By on

    I first tried another spray that did not work as a week later I still had fleas jumping off my dog. I tried Knockout after reading reviews and I can say after a week - NO FLEAS! We sprayed furniture, carpets, around the floor were the dogs beds are and vacuumed daily for a week straight. A lot of work but I have heard horror stories on fleas getting out of control and I was not having it. I made sure I had windows open and a fan blowing the air out of the house to avoid a chemical smell lingering in the house. I would recommend and will use again if needed.

  • Knockout worked on a tough flea problem!

    By on

    Our house was infested (even though our cats are indoor-only). We tried a lengthy remedy using a powder-based treatment where the powder had to be swept into our carpets. Required extensive vacuuming. Did not work. Bought Knockout next, based on a friend's recommendation. Our miserable kitties finally experienced some relief. Me too, since the fleas were biting my ankles! Two cans were enough for our house and my car, which also became infested after a trip to the vet. Sprayed carpet and undersides of upholstery. Killed all the fleas. I can't recommend this product enough. Chewy's quick shipping time was a huge help, too.

    A kennel owner recommended this spray to me. I was thrilled to find it on Chewy at a very reasonable price. Not stinky, sprays great.. just where it's pointed, and best of all it works. I have been battling the fleas for the first time in seven years. This has helped me gain control and I will reorder and recommend it to anyone !

  • It works well.

    By on

    I had an infestation. I tried the bombs from the store. They didnt work at all. So I read up on fleas. Took ALL of my clothes to the laundry mat and washed them in hot water. I vacuumed well and threw the bag away. Then used knock out. With in 48 hours I had no flea activity. I'm allergic to fleas. So I know they are gone!

  • Basement flea infestation, cat household

    By on

    Putting down an established flea infestation is a very, very tough job. It is best to use professional help as we eventually did, for our basement. New York State has regulations which prevent residents from buying pesticides that pro's are licensed to use, such as Tempo SC and Temprid. We tried a couple of over the counter products, foggers and fumigators, which did nothing at all that we could observe. Then we used a can of Virbac Knockout ES Spray, which made a significant difference for about 24 hours. It does work. Perhaps if you use a lot of it, several cans or more, you may find it sufficient for your particular problem. Beyond the above comments, the first and most important point is Putting down an established flea infestation is a very, very tough job.

Perhaps if you use a lot of it, several cans or more, you may find it sufficient for your particular problem. Beyond the above comments, the first and most important point is the following. It is imperative to use Advantage II topical imidacloprid on all your cats at the recommended intervals. Advantage II really works close to perfectly and kills everything on the cats. But one must be aware that if there are any fleas alive or hatching out in the cat's environment, they will reappear on the cats. Our flea infestation occurred because we took in a homeless outdoor cat that was domesticated, but relatively hard to handle. I therefore failed to treat him in a timely manner with Advantage II even though we had plenty on hand. I know better, but I blew it, and we paid the price. One last point is just a matter of common sense, but it has been very important for us. Get everybody in your household white pants and socks and wear nothing else in the area of infestation while the fleas are present. You must be able to see them on your clothing or you yourself will carry them everywhere. … more

  • THE BEST... Been Using It For Years!

    By on

    Knockout E.S. is the BEST...We have used this for years and years, It really works! Sometimes we go for several years with not a flea in sight, but when they do show up we use Knockout E.S. Having multiple dogs we have to make sure we keep the upper hand with fleas and KNOCKOUT E.S. does the trick. Highly recommend.

  • Knocked out the fleas!

    By on

    Our family went away on vacation for a week and it got very humid in the house. My cat and dog both wear a serresto collar but I got attacked by fleas when we came home. I think they were lying dormant. I vacuumed every day, I put down baking soda and made flea traps...nothing worked. I ordered knockout on a Tues and got it the very next day because chewy.com has the fastest shipping ever! After I sprayed the house down within an hour I had no more fleas and it's supposed to keep killing them for 7 months afterwards. I would recommend this product. It's faster and more effective than doing a flea bomb.
