  • WORKS WELL

    By on

    This works much better tan Hartz or Hotshot. This killed 95+% of the fleas in a few days. However, it doesn't seem to last for more than a couple of weeks with one application. Two applications should wipe out the fleas for good. Easy to apply with the inverted can with no waste.

  • Won't do 2100 sq ft

    By on

    My Vet recommended this product as he uses it at his office. I was planning to spray my house which has about 1800 sq ft of carpet. The can says it will do up to 2100 sq ft. After 400 sq ft, the can was empty. I did not over spray. I just did a light mist with a sweeping motion. That is disappointing. I like the Chewy company but this manufacturer doesn't help their image.

  • 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.

  • 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.

  • Good stuff!

    By on

    I used this along with a topical flea medicine, and this spray worked wonders. No other spray did anything. We got rid of our flea problem in no time.

  • Thank you for making this product!

    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.

  • 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!
