Instructions

Hold can 2 or 3 feet away from surfaces to be treated. Be sure to apply uniformly using a sweeping motion to carpets, rugs, drapes and all surfaces of upholstered furniture. Be sure to treat all surfaces of pet bedding as this is a primary hiding place for fleas. No need to remove pet bedding after treatment. DO NOT TREAT PETS. Use a registered flea control product on your pets in conjunction with this treatment. Avoid wetting furniture and carpeting. A fine mist or spray applied uniformly is all that is necessary to kill fleas and ticks.

  • not effective

    By on

    Sprayed entire house at one time to eradicate problem. Fleas came back very next day on our couch--and kids still getting bitten a few days after spraying the basement. We have had a pest company come, and believe me, after they spray, no fleas for 2 weeks, anywhere...until the eggs hatch. Thought I'd save the hassle of having exterminators come in since the fleas are almost gone, but unhappy and surprised how ineffective this (highly-promoted by my vet) product was. Left globs of white residue while I sprayed, and too much work covering all toys / books not to be covered by the aerosol.

  • Not recommended for inside...

    By on

    Not sure yet how well this product works as I still have tiny fleas jumping on my feet/ankles on my back patio where I've sprayed twice. To me it has an unpleasant odor so haven't used it inside. I had a terrible infestation so can only assume with all the products I've used it is better. Guess I expected immediate relief.

  • Stuff works great

    By on

    I've used this product before and it works great. If you use it let it dry, it does smell. About a week or two later spray the same area again. It works. Keep pets out of the rooms sprayed and off the furniture until aired out and dry. Best product available.

  • Use it as directed

    By on

    The odor is strong so be sure to have a mask when spraying and your animals removed. The smell subsides and goes away once dry. It seemed to have worked well, but I will likely treat once more in 3 weeks just to be sure. I sprayed everything in my 1 bedroom apartment (790 sq ft) and needed 2 cans.

  • 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!!

    With one application, the fleas were gone! The review needs to be 50 characters, but nothing else to say!

  • Knockout is an excellent flea control product!

    By on

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

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

  • 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.

  • 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.
