    LOVE IT SO MUCH!!!

We tried sprays and bathing them once a week, Terminix came out and sprayed and still nothing was slowing them down. I used this and within 24 hours there were barely any active fleas. I sprayed again this evening and I’m betting we won’t have any active by this time tomorrow. This was LITERALLY A GODSEND! We’ve been boarding our cat and dog and I called today to extend until we can 100% be sure they’re all gone before bringing them back home! We also sprayed our yard to cover all bases! … more

    Didn't hold its end of the bargin

    By AussieOwner on Oct 12, 2020

    Verbal did kill the adult fleas but 2 weeks later my house was infested again. The claim that it will last for months did not hold up.

    Not Working

    By on

    We used Knockout ES four days ago. I can't walk anywhere still without fleas getting on me. Yesterday as I went to leave for work as I got to the door I counted 20 fleas on my feet and legs! We are vacuuming once or twice a day. I have to check myself before going into work, yesterday found one just as I entered the office and ran to restroom to get it off. We are not waiting two weeks my husband is spraying again tommorrow. I thought would at least.see a reduction in them. If next spray doesn't show some results will.have to call exterminator, more money. Treated cats with Petarmor Plus a week ago and isolated thrm to one room, it isn't working either really and don't know what else to We used Knockout ES four days ago.

    I think it works but

    By on

    I recently brought home a little Chihuahua as a foster and she had fleas. I freaked out and thought my home would get invaded so I gave all my dogs Nextgard and cleaned/vacuumed everything. I was also looking for a product to treat my home when I found the Virbac and all its great reviews. I used it as directed and I think it worked as I haven't seen a flea again (that was about a week ago). However, I wasn't even half way through the bottle when it clogged! I had bought 2 bottles just in case I needed more product so I was able to finish the job with the second one (and I still have plenty of product left) but it felt like a rip off to spend $21 for it and just be able to use half of the product I recently brought home a little Chihuahua as a foster and she had fleas.

    Won't do 2100 sq ft

    By on

    My Vet recommended this product as he uses it at his office. I was planning to spray my house which has about 1800 sq ft of carpet. The can says it will do up to 2100 sq ft. After 400 sq ft, the can was empty. I did not over spray. I just did a light mist with a sweeping motion. That is disappointing. I like the Chewy company but this manufacturer doesn't help their image.

    Not sure if it works

    By on

    I treated my carpets with Virbac after using oral and topical medications to get rid of existing fleas on my dogs. Good news is the Virbac doesn't smell. Bad news is that the dogs still have fleas. Obviously, something didn't work.

    short term results average but fleas returned in days

    By on

    Initial results were positive, but the fleas returned with in a couple of days. I used this product several years ago and had excellent results, both short and long term. Conditions were similar so not sure if the formula has changed. thanks, JB

    Not a solution

    By on Top 1000 Contributor

    I think I heard the fleas laughing at me. It did nothing to deter them. I am going back to Mycodex.
