  • I think it works but

    By on

    I recently brought home a little Chihuahua as a foster and she had fleas. I freaked out and thought my home would get invaded so I gave all my dogs Nextgard and cleaned/vacuumed everything. I was also looking for a product to treat my home when I found the Virbac and all its great reviews. I used it as directed and I think it worked as I haven't seen a flea again (that was about a week ago). However, I wasn't even half way through the bottle when it clogged! I had bought 2 bottles just in case I needed more product so I was able to finish the job with the second one (and I still have plenty of product left) but it felt like a rip off to spend $21 for it and just be able to use half of the product I recently brought home a little Chihuahua as a foster and she had fleas.

  • Relief from fleas!!

    By on

    I have a cat and dog that both ended up with fleas. Trying to battle the infestation within our household was next to impossible. We tried out a new vet which recommended Knockout spray. Needless to say after trying everything else we thought would help we are finally flea free. This product is amazing. Yes, it is a little more than we had hoped to spend but in the end I wish we would have tried this first because it would have saved us a ton of money. Don't waste your time with any other products out there this will do the trick the first time! Thank you Chewy for the extremely quick delivery as well that sure helped in our desperate time of a flea infestation.

  • Knockout Works!

    By on

    This product will definitely help in eliminating fleas but it is an ongoing process to get rid of fleas no matter what you do but I will say it was the first real relief - after using knockout. Chewy also sells cedarcide and together they were wonderful- you can put that one on your body and it is non-toxic.

  • Disappointed

    By on

    I read all the reviews and thought this would work. I sprayed and waited a few days and sprayed everything again. I'm not sure if I have unkillable fleas or what but still have them. It got rid of them for about a day or so and they were back. Think I'm just going to call an exterminator now.

  • Fabulous!!

    By on

    I've used this for years. This past summer I tried the natural route because I couldn't find this locally anymore. Finally, after a month of dealing with nasty fleas, I came online to find this because I know it works. Happy pets, clean home.

  • 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!

  • Decent Flea Control

    By on

    I bought this to use along with the professional spraying I had done in my home. I had a major problem suddenly and yet my cats are indoors 100% of the time. I believe I tracked the fleas in when I had a deer die in my yard. Such an ordeal.

    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

  • 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.
