  • Super Product at an Unbeatable Price

    By on

    My vet had recommended Knockout when I moved into a rental house infested with fleas. I bought the first can at the vet's office for about $29. I have to spray the entire house every three months for the next year to make sure to kill all of the fleas at the pupae stage (hardest to kill at that stage.) Spraying the entire house took the whole can. I tried another spray that had similar ingredients to save some money. I don't want to take the risk it doesn't work, so I shopped online and found that chewy.com sold this product at the least expensive price. Win-win for me. I get the vet recommended product at 1/2 the cost. Yeah, chewy.com!!

    I have used knockout in the past but it's been a long time. I'd forgotten just how effective it is.

  • Best Flea Treatment Ever!

    By on

    This is a great product. You can do a room at a time or the whole place and it really does work for months. Unlike foggers, this gets under and behind things--highest recommendation.

    My cat avoided her bed area for a few days, but the product works well, and does not stink.

    But...flea infestation isn't often something we can handle ourselves. These room sprays have been good (and I like this brand), and in combination with pills from the vet and monthly topical treatment, it provides relief, but finally day-boarding of pets and professional spray bombing of premises may be necessary.

  • Excellent spray

    By on

    Works as soon as you spray the whole area. Applied again 2 days later just to make sure, now I don't worry about fleas in my basement. Will order again just to have on hand.

  • no matter how much you shake it, it doesn't spray evenly

    By on

    I ordered 4 cans and with each application, clumps of foam spurt out on my rugs. Per the instructions, I shake it vigorously prior to using...but it doesn't consistently spray a fine mist. Very frustrating.

  • Great product that works!

    By on

    I used the product on carpet and pet beds and saw immediate results the first use. I will keep it on hand for future needs. It really made a beneficial difference and the odor was not very harsh at all. Thanks Chewy!!

  • This product does work

    By on

    I have spent tons of money trying different product for the flea problem i had in my home. I have used foggers, spray, carpet powder and nothing worked. It was easy and a lot less work then when you use the foggers. I went on Chewy's website and saw a lot of good reviews and thought I would try it. It has only been two weeks but so far it has worked great. We are no longer seeing fleas on our dog. We will do it again in two weeks just to keep up on it but I would recommend this product.

  • Great product!

    By on

    I used this product for an severe outbreak once and it worked great! My cats have skin issues and I cannot use any of the topical flea repellents so I now use this product as a prevention measure combined with Capstar if needed and I have not had any trouble in almost 2 years.
