Virbac Knockout Area Treatment Spray, 14-oz can

I will admit it I have a flea problem or infestation. I got this in hope it could be controlled until the snow hits next month. I have three cats and one dog. Knockout not only got rid of fleas upstairs in kids rooms but also downstairs it has helped a lot. I still have fleas in the house but every time you walk the dog and cats they hitch a ride. But I keep spraying every day and it cuts it in half if not more.

We bought one can and treated the house, it worked for a few days and the fleas were back! We decided to ramp up our efforts and bought 2 more cans plus some spray for the yard and new treatment for the pets. Gave all the pets (2 small dogs and 1 cat) a thorough bath and when they dried, applied the new treatment. Vacuumed the entire house and sprayed this stuff very well. Also treated the whole yard, especially around the house. For a few days, we were flea free but they are back! I can't keep spending money on this stuff!

We had a really bad flea infestation in our house, sprayed this on the carpets and 90% of them were gone in a day! I still get a few straggler bites as the numbers go down but it works pretty good. In addition Chewy Customer service was phenomenal!! There was an accidental double charge on my card, I emailed them about it and they clarified which charge was wrong the next day and immediately posted a refund! Very easy and super helpful!

I have 2 cats one indoor,and the other goes in and out, I have them both on Revelution flea medicine,topical once a month,since the one kitty goes in and out,I use this spray about once a week,I just spray areas they sleep or hangout,and I have had no problems with fleas! I'm in Florida and we get heat and fleas bad, just keep pets out of area until it drys

I usually buy this from the vets office but it's cheaper from the Chewy website so I'll buy from here from now on. Very effective and easy to use. I've always had success with this stuff. I would recommend using this in the house and capstar on the animals followed by whatever flea meds you use on your pets.

I’ve used the spray that comes from the veterinarian, it’s the real knockout spray. This stuff is junk. For $20 a can, I expected the real deal. NOT. Complete and total waste of money. Used precisely to the directions on the can. Did absolutely nothing. The fleas are now worse, due to the time I’ve wasted using this crap

We've been spraying this EVERYWHERE (carpet, furniture, bedding) each week after vacuuming, in an attempt to keep the fleas on our three dachshunds under control. Our home seems to remain flea-free but our dogs are another story... I'm beginning to wonder if anything can keep the TX fleas in check! I'm a bit wary of the harsh chemical smell (which irritates my chest a bit) but I quickly vacate the area after spraying and don't notice it two hours later. This product is easy to use, but, once the can's down to about a quarter full it stops spraying so effectively and you get wet blobs of foam coming out (I guess the aerosol runs out before the product?). After one month, we're already on to can We've been spraying this EVERYWHERE (carpet, furniture, bedding) each week after vacuuming, in an attempt to keep the fleas on our three dachshunds under control.

It works unless if you have a very bad infestation of fleas. Then you need to use it 4-5 times a day.

We had a really really bad year with fleas in my area. Basically anyone I knew or heard of with pets had fleas, And I tried everything. I bought this after reading reviews thinking at this point what do I have to lose, and it's low cost. Sprayed the basement which is where ground zero was and in less than a week the numbers dropped drastically and by the end of the week they were all gone. All. Of. the. them. These little guys are attracted to me like crazy and I could take one step down there and they would just cover my legs. Nothing. I stopped seeing them upstairs, no more in the vacuum. The animals were all clear. Well worth the money. We are buying a few more cans for the upcoming season We had a really really bad year with fleas in my area.

We are buying a few more cans for the upcoming season because it was so nice not seeing these demons in my house and I will make sure they are out this year. If you have tried almost everything you can think of, buy a few cans of this, follow the instructions and spray away. Seriously. You will be glad you did. … more

Knockout is great for getting rid if fleas. Be sure to remove pets and food from areas before you spray.
