Customer Ratings & Reviews

Rated 4.5 out of 5 by 11 reviewers.
Rated 5 out of 5 by Great product I have used this for years, and it really works, but everyone needs to understand that if you have a mild or heavy flea problem, you must treat the yard, house and your pets all at the same time. If all 3 are not treated at the same time people think that this and other products do not work. May 31, 2014
Rated 5 out of 5 by if you have fleas.......YOU NEED KNOCKOUT ES NOW!!! Oh my gosh, what a nightmare, in all of my 55 years of living and always having indoor cats & NEVER having fleas before, this product saved myself from going bonkers in trying to eradicate my home from these uninvited bugs. Works great when you spray everything, under couch cushions, rugs, mattress, every thing you can see where the cats may have been which is EVERYWHERE!!! Also, following a strict routine of washing everything & the most important twice a day everyday for a few weeks VACUUM!!! Throw out bag every time or put flea collar in it & freeze bag until use. The problem with fleas is all the eggs you cannot see. These little bugs were in the cracks of my new wood floor, and trust me I am super clean!! Good Luck & don't worry, once you use this your old life with no fleas will return shortly!!! August 1, 2014
Rated 5 out of 5 by Great product! We used this home spray last year, when we had a ridiculously heavy flea infestation. We got it from our vet, and after flea baths, Comfortis, spraying the yard, and then vacuuming and spraying with this product, we had no more fleas, for a year! Saw the first fleas today, so it is time to spray! It really does last 7 months! May 31, 2014
Rated 5 out of 5 by this product is by far the most effective on the market today, surpassing even the professional exterminator's product. With 4+ effective insecticides in one and a fast dry rate whereupon the home can be reinhabited within hours, this product is the best. I have tried everything else. Next step would have been fumigating entire house encased in plastic. KEY IS TO TREAT YOUR YARD IN SPRING AND FALL , every 2-4 months. Don't forget the pets too. January 31, 2015
Rated 5 out of 5 by great product My house is now a dead zone for all invading critters. Have not spotted a flea since using it. December 1, 2014
Rated 5 out of 5 by so far so good i had a bad flea problem had used other products and still had baby fleas used this and so far have not seen any more September 3, 2015
Rated 3 out of 5 by Not That Great This product is supposed to cover 2100 sq. ft. I have used 4 cans of this stuff in my 2000 sq. ft. home and, three weeks later, I am still finding fleas on my indoor-only kittens. I used the products on all carpets, rugs, draperies and furniture. November 11, 2015
Rated 5 out of 5 by Better than the Pros We hired exterminators for fleas at my home and at my Mother's home. Both houses were treated -- still fleas! We sprayed with Knockout ES. Major change in flea populations, a second treatment and the fleas were completely gone. The odor of the spray dissipates quickly and it dries well -- even on wood floors and carpet. I bought extra cans so I can always have it in the garage. October 30, 2015
