Virbac Knockout Area Treatment Spray, 14-oz can

We have a Labradoodle and a cat, and had a flea infestation this summer. We tried everything - diatomacious earth (don't ever expect this to work, it DOESN'T), borax, all the "green" remedies. Trust me folks, going green does NOT work when it comes to fleas!! Give me the CHEMICALS!! Speaking of chemicals, though, even an professional exterminator that our apartment complex provided (free of charge) came in and sprayed and we noticed no relief whatsoever! So I started researching, and found that if you have a flea infestation, you need to use a product that contains IGR - Insect Growth Regulator. Knockout has it. I sprayed the apartment as soon as I got the can in the mail, and trust me We have a Labradoodle and a cat, and had a flea infestation this summer.

The pets were so comfortable, no more bugs crawling on them sucking their blood. Bottom line.....the best ever!!! … more

It really works. I sprayed every soft surface I could 1st time around. Started finding dead fleas the next morning. Only down side is it doesnt cover the 2100 sq feet. I vacum every day and do a light spray 1 time a week because fleas come in waves for about 6 months. I will keep this spray on hand!!

This stuff is the real deal. I had rescued a kitten from a terrible pet store. The kittens coat appeared to be moving. After bathing, combing and treating the kitten, consequently my apartment had fleas. This product worked amazingly.

I got bit "7" times just sitting on my chair. I was so furious that I started googling for a product that would work. And by Golly this did the Job. Amazing Stuff. We all live a better life in the house including my dogs...

The fleas were really bad this year at our house and the treatments didn't seem to be helping our cats. We used this on all of our carpet (including rugs). We vacuumed after it dried and continued vacuuming every day (and emptying outside afterward). About three days later I started seeing fleas again, but kept up the vacuuming and it has now been a week and a half since spraying and I haven't seen another.

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.

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.

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!

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

It's one of the better treatments I've come to use but not the best. Still for the price I'd recommend giving it a try.
