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 5 out of 5 by Came Highly Rated Though our pets all are treated with Frontline, we noticed a couple slow-moving fleas on them after a hot and humid couple of weeks. Just as a precaution, we used this product on our carpeting. We never actually noticed a problem in the carpeting, but once you see one of those buggers, you can't bring out all the 'big guns' fast enough. The situation was rectified in a couple of days, but I'd use this product again if those ugly beings showed up again in our house. I think the Frontline did it's duty so don't forget to always use it on all your pets, even your indoor kitties because once the flea is in the house, they'll go wherever they can. July 11, 2016

Rated 2 out of 5 by short term results average but fleas returned in days Initial results were positive, but the fleas returned with in a couple of days. I used this product several years ago and had excellent results, both short and long term. Conditions were similar so not sure if the formula has changed. thanks, JB July 19, 2016
Rated 5 out of 5 by This is a great product We had flea problems with both cats & a dog OMG it was bad we took them to the Vet they got taken care of & they recommended Knockout ES area treatment spray it works. Within a day or two we could tell the difference. My home is not that big so a few days later I used it again. I highly recommend this product. It's cheaper online then at the Vet Store, if your having problems, please spend the extra money on this it's worth it to you & your pets. July 7, 2016
Rated 5 out of 5 by I will use nothing else... Knockout spray is the only product I will use. I spent several years working in a veterinary hospital, we always recommended Knockout to clients and never heard a complaint. Now as a rescue owner, I treat every 6 to 8 months and it keeps fleas under control. I like that it has a residual effect that keeps killing fleas for months. June 22, 2016
Rated 5 out of 5 by My vet sold me on this product. As long as I have animals in my home Virbac Knockout E.S. Area Treatment Spray will be high on my list of must haves. A little spraying every now and then and treating my animals with their medication and I never have to worry about fleas, and the price at doesn't hurt my feelings like at the Vet office.
