    This was the product that finally got rid of the fleas

    By on

    I have two small cats, 8 months old. I don’t need to tell you what a pain fleas can be. My cats had them for about 3.5 months. I tried everything. Flea shampoos, a flea bomb for the apartment, Revolution. I was laundering my clothes, towels, blankets and cat toys several times a week, keeping my clothes in plastic bags, and stripping out of my clothes before walking into my bedroom, to avoid transferring fleas to my bed and clothes. It wasn't until I sprayed down my apartment with this product that the fleas were finally gone, and almost immediately. It was maybe 2 days after using this when I stopped finding fleas in my cats’ fur. The important thing to realize is that in order to break the I have two small cats, 8 months old.

The important thing to realize is that in order to break the life cycle, you need a topical to kill the fleas ON the animal, combined with a treatment for the house. Otherwise the fleas on the animals will just jump right back into the environment and vice versa. In retrospect, I should have used this product much sooner. I would have STARTED with a combo of Revolution and this spray. Note, the spray I used was the “E.S.” spray. I haven’t tried the regular kind, which is less expensive, but from those reviews it seems like this is the more effective one. Just make sure to lock the animals in another room (mine were in the bathroom with towels in the door cracks), go nuts spraying everything (there's surprisingly a lot in the bottle), and then get out of the space yourself for a couple hours. … more

    RESULTS.......finally !

    By on

    I bought 3 cans & used from room to room after isolating my flea-ridden cats.....who WERE on preventives monthly. It did take several repeat applications before it worked, but FINALLY - NO MORE FLEAS ! I kept the cats in 1-room & sprayed all the others, then isolated the rooms by closing the doors. I washed ALL bedding, vacuumed like I had OCD, & vacuumed some more. THANKS, CHEWY for getting this to my home ASAP ! ! ! As always, you guys ROCK

    No worry product

    By on

    This spray works very well I would recommend it to other dog owners. Even though I have tile floors throughout my home I do spray my dogs bedding with this product as well as the dust ruffle around my bed and the throw rug in the living room. My dog has never had a reaction to the product nor have I had a flea problem.

    Excellent product

    By on

    I have been using this for a few years now from my vet. I was so happy to find it here on chewy. It is the quickest and most effective product I have found for getting rid of fleas and other pests. A small amount goes a long way with this.

    Extremely Effective!

    By on

    I have treated once with no issues since! I have 14 cats so when fleas magically appeared in the house I thought it was going to cost thousands! Capstar for each cat and all areas treated with Knockout and I was done! That hardest part was getting my supper skittish and semi feral cat out of the room I was treating. He doesn't like to be picked up and his "safe space" is on the room that was in most in need of treatment

    Knockout - This stuff Works

    By on

    Knockout flea treatment really seems to work. It is pet and human friendly, easy to apply and effective if used a few times based on the flea life cycle. If like me, the fleas seem to turn to you once the pet is treated and no longer a fit meal, I recommend Skin So Soft plus w/Picaridin. Strong scent, but protects humans from fleas until their life cycle ends.

    Worked for us!

    By on

    I had treated the cats, washed everything multiple times, was vacuuming several times a day, every day, (and emptying out the canister each time) and we STILL HAD FLEAS. I was using a "natural" surface spray and while it was helping a little to keep the problem under control for a few weeks, it wasn't getting rid of them. And when we stopped using that natural stuff, the fleas got super bad. I was at my wits end and I purchased knockout and continued vacuuming/washing. 1 1/2 cans and I was able to treat the whole house (1100 sq ft). I thought we were out of the woods but then I started seeing them again so I treated the whole house again and I am happy to say I haven't seen any fleas since, and I had treated the cats, washed everything multiple times, was vacuuming several times a day, every day, (and emptying out the canister each time) and we STILL HAD FLEAS.

    Saved a very frustrating situation....

    By on

    I live out in the country, across from a dairy farm, and found myself in a nasty situation of a flea infestation! I had tons of them, couldn’t get rid of them, even though my pets were treated monthly and I was vacuuming daily. It kept getting worse. I tried two other products (one a spray, and one a dust that you leave down and vacuum up later) from Walmart that just didn’t work. Waste of money. I have a small house so I bought two cans of this to make sure I would have enough. I only used half of the first can!!! Not only is it cheaper than any other product but it really worked. It took about three weeks to really get rid of them (mind you, I only used the product one time since it will continue I live out in the country, across from a dairy farm, and found myself in a nasty situation of a flea infestation!

I had fleas hatching for a couple weeks after spraying, but they almost looked deformed. It was like they were flat! So weird. Anyways, I used the product per the instructions (a very fine mist) and within three weeks all the flees are gone. None jumping onto white socks, none on the pets, and none in the vacuum cleaner!!! I was SO relieved to find an answer to something I’ve been dealing with for four months now. Couldn’t recommend this product more!!! … more

    AWFUL, fowl smelling

    By on

    Not only does it stink to the point of taking your breath, it takes 24+ hours to dry, even with the window open and the ceiling fan on. And I can't tell that it did the least bit of good. Perhaps it would do better in the spring when you can open up the whole house.
