Excellent product. Use outside my home in spring and fall. Never any issues with fleas.
This is the best area treatment on market today. Typically one treatment to home environment and my normal topical products from veterinarian and DONE gone! No more fleas for season!
very highly recommended by my veterinarian.
I have used this product before many times from my vet, here it costs half it works THE BEST at removing fleas.
This is the BEST stuff I've ever used for fleas and ticks. It kills everything! Plus it's safe for my kids and pets to be around. It's simply amazing!
AMAZING!!!!
I use Knockout if I think the fleas are in my carpet, etc. I spray around the baseboards of the entire house, then I spray furniture, and places where dog and cats sleep. It works great!
Great Price, good selection, and fast shipping what more could you ask for!
have used before, works weel, seems to last a long time
Knockout, is really a knockout. I tried using flea bombs and they didn't work as well. I still had fleas all over my house. A friend of mine told me about Knock Out , I purchased it. Still skeptical, used it and after that. No more fleas. My flea problem is NO MORE! It is gone! Finally! I cannot say enough good things about this product!
My skit is a 3-year-old indoor cat. Who I love very much. I have been using Knockout Area Treatment for a while now and if it was not for it I could not have her inside the house. It has never let me down and my pet has remained free of fleas.
I've used KnockOut Area Treatment Spray twice now and both times, it's worked as described. It immediately killed the fleas and I sprayed a second time a few weeks later to kill what were the eggs and didn't have a problem. I treat my furniture, rugs and carpet. It does last like it says. I would recommend to anyone who wants to keep the fleas away.
