Rated 4.6 out of 5 by 16 reviewers.
Rated 5 out of 5 by This product is great! In the past Ihad to purchase Knockout in the larger city 30 miles from my home. I purchased this product, at a veterinarian office prior. Chewy has made it possible to have it delivered to my door and at a great price. This product is amazing! Just a couple of treatments and fleas are gone. Thank you April 30, 2016
Rated 5 out of 5 by Legit flea killer If you want to get the fleas taken care of the right way, use this. The chemicals in this are used by professionals all the time to kill fleas. I would keep any cats away from the sprayed area for as long as possible though. April 15, 2016

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 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
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
