I just moved with my family into a new rental that had been empty for some time. We speciafically asked the agent for a place where the previous tentants didn't have any animals. It was the worst I'd ever seen of fleas. The house was smoked out but it didn't work, and as a last resort I bought the Knock Out from Allivet. Happy to report that my home is now free of fleas. This product is amazing.
Best known product to eliminate Fleas and Tics for 1 full season
We had never experienced any flea outbreaks before, but last summer was brutal. I had 2 very miserable dogs. Our vet recommended Knockout and it was a great help. The misery for my dogs was over.
I am a repeat customer of this product. I know that when my dog gets fleas this will rid him of it. Each time I have ran out and have bought from Allivet it has arrived on time. Thank you Allivet.
The key to keeping your dog free of fleas is keeping their living area free of fleas. I kept wondering why my dog kept getting fleas even if I used flea protection on him. My lawn guy told me what happens is you kill the fleas on your pet but I was leaving them behind in he’s living area. I bought KnockOut Room & Area Fogger, fogged he’s living area. At the same time he was at the vets getting the works. He has now remained free of ticks and fleas KnockOut Room & Area Fogger really helped.
This product does an excellent jobs for around the home. It is easy to spray on areas that need to be treated without fogging an entire house or room. It works better than the fogger. I noticed an improvement within a day or two.
