Rated 4.4 out of 5 by 36 reviewers.
Rated 3 out of 5 by helped somewhat 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. September 9, 2016
Rated 5 out of 5 by Truly AMAZING I was being attacked like crazy, my apartment is all carpeted and getting getting off the bed was a nightmare, id have about 10 miniscule blood suckers on me everytime i walked on the floor. I swear they just seemed to appear in a week. My poor fur babys hated them too. I powdered the floor like 3 times vacuumed and they persisted, i bought a hand spray still they seemed to attack more. Finally after reading reviews i caved in and got 2 of these bottles of virbac knockeout e.s. area treatment spray can 16 oz. Omg this stuff is AMAZING i can walk in my home again and they seem to be gone. Also i treated my cats with capstar pills and it works like a charm, these two products together truely brought peace and comfort back to my home. By the way, i only needed one can for my two bedroom apartment, still im keeping my other bottle for peace mind. Truly amazing stuff. Thank you virbac. June 24, 2016
Rated 4 out of 5 by Much improved Spray definitely helped a lot, but I still have fleas! September 8, 2016
Rated 4 out of 5 by One of the best! Was about to lose my mind with FLEAS! I sprayed, washed clothes and vacuumed likes crazy person! The only spray to purchase - one of the best! I hope they never come back! (I bought 2 extra cans just case!) September 3, 2016
Rated 5 out of 5 by Works great!! I have bought this product in the past from the vet. This stuff is the same product the vet sells only at a cheaper price. I recommend this product to anyone who has a flea problem. September 5, 2016
Rated 5 out of 5 by Excellent for combating fleas! We found out our cat had fleas, & WOW when they say 2-4 months to be rid of them in your house-they mean it. We are going on 2 months and have seen a major change because of using this product. We used this product on select items in the house. Because this is heavy chemicals we used it sparingly since we have kids. We also used Diatomaceous Earth, and with the combination of the two products so far we are winning the battle. Also a plus that one dose of Knockout is good for 7 months. Great product! August 22, 2016
Rated 1 out of 5 by Would not buy again Followed all directions and I still have fleas, wasted money, big money. August 18, 2016
Rated 2 out of 5 by Not a solution I think I heard the fleas laughing at me. It did nothing to deter them. I am going back to Mycodex. August 17, 2016
