Best Deal on the Internet
This stuff is great. Once you get fleas in your carpet it's hard to get rid of them. Knockout is very effective. I haven't been able to find it in stores anywhere so I'm thrilled that I found a place online at a great price!!!
just what l needed

Best in the Market

Spray where you need to..unlike foggers. Keeps the fleas out of the house. I also use Virbac Ecto-Soothe 3x shampoo to keep the fleas and ticks from getting on the dogs. Both products work great. Keep the dogs happy and we dont have the flea issues.

I had excellent results with this product. Effectively killed the fleas and has kept them away. What I really like about this is you spray where you want it unlike a fogger that goes EVERYWHERE. So you would have to wash your dishes, counters, etc

This product is a miracle...killed fleas on the carpet instantly

Knockout helps kill the fleas that are living in your house all your long. But do not spray knockout on your pet.
Very effective for carpeting, furniture, draperies, and bedding.
don't waste money on other products. go straight here!
Satisfied with Knockout Flea Spray
from Fremont, CA10/21/2011
My house was really infested with fleas and I've tried a lot of products, so with that said, Knockout didn't kill every flea but I think it made a difference and really reduced the population. Even though it says it will last 120 days I plan on using it monthly until I don't see anymore. That and vacuuming everyday, and using Advantage on my dog. Don't expect one product, or one application to wipe out all the fleas.
shipping takes FOREVER!! (they can only ship it by ground. so no over-night shipping EVEN IF YOU PAY FOR IT!)!! I had a flea problem and I had to wait for over a week for the product to be delivered. By the time it got here, I had to pay for an exterminator. They said they would give me the shipping money back but never did. The dude on the phone was a dick to me, also (just so you know)... I mean, a complete a-hole.

This stuff is really awesome and very easy to use. Best of all...it works!
Had quite a flea infestation but they're gone now, so I would say it works well :)
This stuff is amazing! I had a flea infestation despite treating the yard, the dog and the house. I sprayed with this according to directions and that was it.
Knockout - Great product
I have 4 cats & a dog. The last few mths have been horrible at our house with fleas. We put the flea stuff on the animals & sprayed the house with knockout daily & then vacuumed daily. My fleas are gone after only a week.
Good Flea Killer!
This product works great without any really bad odors. I did have to spray once a day for 3 days in certain areas, but the fleas were pretty bad to begin with. I only used it in areas away from my bird and gecko, and I had the windows open and fans going just in case, but no issues to worry about. It did knock out the fleas and so far, in conjunction with regular pet treatment, the problem is under control again. Flea season is outrageous in Central Florida due to a mild winter, so under control is about as good as things will get for a while! Good product!
This product is a good product, but I had a problem with this company. It gave me the option on line to select express shipping and my product did not arrive for over 10 days. Satisfied with the product, but not the company.
always have it on hand
This product is a must in my home. Used it for years. I have even bought a can for my sister to use in her 'stray cat' house.
Best on the market
This is the best flea product on the market. I worked for a pet store and used every product we sold and they didn't work. Bought a can of Virbac from the Vet and it worked almost instantly. Found them on this site for more than half the price and bought 4 cans and my flea issues are gone.
Love this stuff
This is the only product that really works!! I had a problem with feas a few years ago and tried everything from bombs to powders and nothing worked. It was like the fleas were laughing at me! They would bite just hours after I bombed. Then I found this product and read the reviews and decided to try it. It was the only thing that completely stopped the infestation. Now I keep it on hand just in case. I spray with the first flea I see and I never have a problem.

Tried everything for 2 months to no avail. Maybe the fleas were ready to give up but this did the trick ...
Works very well!
from Newville, PA10/23/2012
Recommended by my vet but twice the price at his office! So glad I can get it online!
I just used this product yesterday so I can't rate the effectiveness just yet. However there is no nasty smell which is usually associated with this type of product. Ease of use was great. Shipping was extremely fast as with everything I purchase from this website.
This is a great product, at a great price.
from Archdale, NC12/21/2012
Since having to have our cat put down we have been overrun with fleas. Knockout is the best product we have found to kill them. We can safely spray knockout just about anywhere (drapes, carpets, sofas, etc.). We ordered the spray and were told it had been back ordered, Even so, it didn't take too long to receive our order. We have been very satisfied with the spray.
I have used knockout for years. After using it for the first time, we let our exterminator go. This was a hundred times more effective than he was. We spray our house thoroughly twice a year...no fleas, spiders or even flies. Works great.
I have my own grooming business in my home. I have used Knock-out spray for years and have Never had a flea problem in my house. I would and do recommend it to my clients and to anyone who is having a problem with a flea infestation.
incredible product - unbelievable results
my entire home was infested with fleas, my stepdaughter and myself were severly bit by the fleas on our ankles. after using your product we finally found relief. we also used the flea control product on our 2 cats so they would not bring in additional fleas. i will continue to buy this product and highly recommend it to family, friends, and acquaintences. thank you ENTIRELY PETS for your wonderful product.
First-Time Flea Horror
from East Coast08/08/2012
We have sprayed this several times within two weeks. It is better than Raid certainly. I only rate four stars, because the young neighbor downstairs must have a resistant strain of fleas that got onto her dog. He is a sweet cockapoo that wails from being left alone for hours and bugs visibly fly around and off him, so Lord knows what the poor mutt is infested with that has spread to our unit. The student never reported the dog to avoid the pet fee and pet rent and seems not to clean or vet Bear at all. This is a "gated community" and the management and maintenance are too lax and cheap to tackle this crisis. We will order more. Our two little dogs were always on heartworm and flea/tick preventative. Our home is not! We alternate Virbac or an herbal shampoo every other week for their weekly baths. Do every closet, and follow instructions. Seal off rooms, and remove food, toothbrushes, etc. We did the walk-in closet, bathroom, then bedroom, closing each door for two hours, then airing the section out. Then the kitchen in only a few wall areas, pantry closet, foyer, L/R and dining were done the same way, while we were in the other part of the apartment or away.
We cannot use flea control products on our dog because she has an auto-immune disease, so we must control fleas by laundering her bedding, vacuuming rugs and floors, and spraying.
