Best Deal on the Internet by TaysGammy from Texas02/24/2012
This stuff is great. Once you get fleas in your carpet it's hard to get rid of them. Knockout is very effective. I haven't been able to find it in stores anywhere so I'm thrilled that I found a place online at a great price!!!

I was referred to your web site by a friend.

Best in the Market by Mark R from Findlay, Ohio03/01/2011
Spray where you need to..unlike foggers. Keeps the fleas out of the house. I also use Virbac Ecto-Soothe 3x shampoo to keep the fleas and ticks from getting on the dogs. Both products work great. Keep the dogs happy and we dont have the flea issues.
Excellent Product by Amanda W.12/10/2008
I had excellent results with this product. Effectively killed the fleas and has kept them away. What I really like about this is you spray where you want it unlike a fogger that goes EVERYWHERE. So you would have to wash your dishes, counters, etc
Virbac Knockout spray by doggie friend from Wilmington NC02/16/2013
This product is a miracle...killed fleas on the carpet instantly
Kills Fleas by Steve H.04/09/2008
Knockout helps kill the fleas that are living in your house all your long. But do not spray knockout on your pet.
Excellent by Brenda from IL07/20/2012
Very effective for carpeting, furniture, draperies, and bedding.
good stuff by jarb11/28/2012
don't waste money on other products. go straight here!
Satisfied with Knockout Flea Spray by surfbird from Fremont, CA10/21/2011
My house was really infested with fleas and I've tried a lot of products, so with that said, Knockout didn't kill every flea but I think it made a difference and really reduced the population. Even though it says it will last 120 days I plan on using it monthly until I don't see anymore. That and vacuuming everyday, and using Advantage on my dog. Don't expect one product, or one application to wipe out all the fleas.
by from 07/19/2012
shipping takes FOREVER!! (they can only ship it by ground. so no over-night shipping EVEN IF YOU PAY FOR IT!)!! I had a flea problem and I had to wait for over a week for the product to be delivered. By the time it got here, I had to pay for an exterminator. They said they would give me the shipping money back but never did. The dude on the phone was a dick to me, also (just so you know)... I mean, a complete a-hole.

Great Product! by melissa from Indialantic, Florida07/14/2012
This stuff is really awesome and very easy to use. Best of all...it works!
Fleas by Kittymom05/29/2012
Had quite a flea infestation but they're gone now, so I would say it works well :)
Sweet! by Bennie from Florida10/30/2012
This stuff is amazing! I had a flea infestation despite treating the yard, the dog and the house. I sprayed with this according to directions and that was it.
Knockout - Great product by Mel from NY10/25/2011
I have 4 cats & a dog. The last few mths have been horrible at our house with fleas. We put the flea stuff on the animals & sprayed the house with knockout daily & then vacuumed daily. My fleas are gone after only a week.
Good Flea Killer! by ajaffe06/07/2012
This product works great without any really bad odors. I did have to spray once a day for 3 days in certain areas, but the fleas were pretty bad to begin with. I only used it in areas away from my bird and gecko, and I had the windows open and fans going just in case, but no issues to worry about. It did knock out the fleas and so far, in conjunction with regular pet treatment, the problem is under control again. Flea season is outrageous in Central Florida due to a mild winter, so under control is about as good as things will get for a while! Good product!
This product is a good product, but I had a problem with this company. It gave me the option on line to select express shipping and my product did not arrive for over 10 days. Satisfied with the product, but not the company.
always have it on hand by pitygirl from akron,ohio04/22/2012
This product is a must in my home. Used it for years. I have even bought a can for my sister to use in her 'stray cat' house.
Best on the market by Tom02/01/2013
This is the best flea product on the market. I worked for a pet store and used every product we sold and they didn't work. Bought a can of Virbac from the Vet and it worked almost instantly. Found them on this site for more than half the price and bought 4 cans and my flea issues are gone.
Love this stuff by dragonflower from Ct06/13/2012
This is the only product that really works!! I had a problem with feas a few years ago and tried everything from bombs to powders and nothing worked. It was like the fleas were laughing at me! They would bite just hours after I bombed. Then I found this product and read the reviews and decided to try it. It was the only thing that completely stopped the infestation. Now I keep it on hand just in case. I spray with the first flea I see and I never have a problem.
by Yvonne from Charleston SC11/06/2012
Tried everything for 2 months to no avail. Maybe the fleas were ready to give up but this did the trick ...
Works very well! by gaantra from Newville, PA10/23/2012
Recommended by my vet but twice the price at his office! So glad I can get it online!
No smell by jarb from Calif07/01/2012
I just used this product yesterday so I can't rate the effectiveness just yet. However there is no nasty smell which is usually associated with this type of product. Ease of use was great. Shipping was extremely fast as with everything I purchase from this website.
This is a great product, at a great price.
Great product. by silerhome from Archdale, NC12/21/2012
Since having to have our cat put down we have been overrun with fleas. Knockout is the best product we have found to kill them. We can safely spray knockout just about anywhere (drapes, carpets, sofas, etc.). We ordered the spray and were told it had been back ordered, Even so, it didn't take too long to receive our order. We have been very satisfied with the spray.
knockout by cj06/06/2012
I have used knockout for years. After using it for the first time, we let our exterminator go. This was a hundred times more effective than he was. We spray our house thoroughly twice a year...no fleas, spiders or even flies. Works great.
great product!! by groomer6410/04/2011
I have my own grooming business in my home. I have used Knock-out spray for years and have Never had a flea problem in my house. I would and do recommend it to my clients and to anyone who is having a problem with a flea infestation.
incredible product - unbelievable results by tlshcenck10/18/2011
my entire home was infested with fleas, my stepdaughter and myself were severly bit by the fleas on our ankles. after using your product we finally found relief. we also used the flea control product on our 2 cats so they would not bring in additional fleas. i will continue to buy this product and highly recommend it to family, friends, and acquaintences. thank you ENTIRELY PETS for your wonderful product.
First-Time Flea Horror by Maman from East Coast08/08/2012
We have sprayed this several times within two weeks. It is better than Raid certainly. I only rate four stars, because the young neighbor downstairs must have a resistant strain of fleas that got onto her dog. He is a sweet cockapoo that wails from being left alone for hours and bugs visibly fly around and off him, so Lord knows what the poor mutt is infested with that has spread to our unit. The student never reported the dog to avoid the pet fee and pet rent and seems not to clean or vet Bear at all. This is a "gated community" and the management and maintenance are too lax and cheap to tackle this crisis. We will order more. Our two little dogs were always on heartworm and flea/tick preventative. Our home is not! We alternate Virbac or an herbal shampoo every other week for their weekly baths. Do every closet, and follow instructions. Seal off rooms, and remove food, toothbrushes, etc. We did the walk-in closet, bathroom, then bedroom, closing each door for two hours, then airing the section out. Then the kitchen in only a few wall areas, pantry closet, foyer, L/R and dining were done the same way, while we were in the other part of the apartment or away.
by from 06/24/2012
We cannot use flea control products on our dog because she has an auto-immune disease, so we must control fleas by laundering her bedding, vacuuming rugs and floors, and spraying.
Vet Kem Yard Spray is THE BEST by Chloes_Mom07/05/2011
We lived in a home that was up on blocks. The sand fleas were HORRIBLE! Plus, we had two dogs (primarily outside dogs). We just brought home our new born 3rd baby...and I REFUSED to fight the fleas ANYMORE! So, we went to our vet and she reccomended this product. We used it and have had WONDERFUL success with it! I reccomend it to ANY & EVERYONE I can!
Siphotrol Yard Spray by postalwoman111/26/2011
Instructions are very hard to understand.... Seems like it works great for the first couple of days, then works good for a couple of weeks, so it has to be re-applied often if you have problems in your area... Be careful not to water too much before using product as that reduces effectiveness.
Siphotrol by Donette from Dacula, Georgia06/06/2013
We have used this product on our yards for over 20 years. It works so well. I highly recommend it. If you want to have no issues with fleas, ticks, help get rid of mosquito's and flys. This is the stuff for your yard. They also make a version of this for the home and Ovitrol for your pets. Much cheaper and easier to use than Frontline.
Received empty container by Sunny from millbrook ny10/23/2012
The yard spray arrived empty, must have all leaked out during shipping.
Very badly wrapped and packed
I have used this product on and off as needed for over 20 years. At one point in the past 20 years, I housed 5 cats and 2 dogs. It never failed to live up to its claims. Along with regular topical treatments or collars, I highly recommend it for flea control.
Happy pets, happier humans by fleafree from York, PA10/23/2012
Used this product previously a number of years ago. Serious solution applied only in dire emergencies with persistently growing infestation. Expensive but absolutely effective. Great service from EntirelyPets. We'll be back.
Quick Knock Out by Slconfidential from Collinsville IL10/22/2012
I purchased this product and Capstar, because I was doing repeated applications with Frontline and the fleas would never go away.
Once I Capstared everyone, I went to my basement and first floor and covered the area with Siphotrol. I had previously purchased, twice, a spray flea control from the local store and it did not work. Siphotrol did the trick. I have not found any fleas lurking in my home or on the cats and it has been over a month. I have had cats for over a decade and this year, flea season was a nightmare, due to the mild winter. Now I found a product that I trust to solve the problem.
It does the job by flamingo from Houston,TX10/30/2011
I like the product very much. There are so many products out there in all kind of price ranges. This is a product to use. Thanks
Absolute Best by Jasper09/25/2012
I tried everything before I found this product but nothing really worked. They killed the fleas but not the eggs. When I used this product twenty years ago and it did such an excellent job, I haven't had any flea infestations until this year. When the fleas bloomed this time, the only product I wanted was Vet-Kem Siphotrol.
Best purchase by SuzinMcQ from Chesterfield, Virginia03/26/2013
I have never seen or heard of Siphotrol Plus II Premise Spray until visiting Entirely Pets. I ordered it and used it along with K9 Advantix II. I never had such excellent flea control in all the time I had dogs. I now have 1 dog. My dachshund was 19 years old and passed away a few days ago:( But he as well as all my past dachshunds were always protected against fleas & ticks with K9 Advantix II, along with Mac, who my husband got at a shelter 7 years ago. I will continue to purchase that AND Siphotrol Plus II Premise Spray when needed from Entirely Pets. Thanks so much!
THE BEST by Connie09/24/2008
This stuff is the BEST flea controller I have ever found. I NEVER have a problem when I use this. Been buying it for years!!
Unbelievable by Melissa07/09/2008
Tried this 11 yrs ago it killed fleas, spiders, rollie pollies, etc. I could tell where it had been sprayed on the carpet. Recommended by my Vet. I now buy online and use it only in the spider/flea season. Highly recommend.
Amazing by Debbiee11/15/2009
Oh my gosh!!!! This stuff is amazing! My vet recommended it and it has been a blessing. I spray the rooms and leave for a couple of hours and when i return the floor and furniture is dry .
Great stuff! by Roge08/17/2012
Over a period of about 10 days, I had been professionally sprayed by a well-known company, used approximately a half gallon of spray from a farm store and was seeing only minor improvement. ONE spraying of this product and I haven't seen a flea in two weeks!
Really works by Melly from PA11/06/2012
This product is best flea killer for your home. I live in a wooded area with many animals passing through carrying fleas. I have two cats and a dog. I spray the house with this product and it works well.
Siphotrol Plus II Premise Spray (16oz) by schnauzer lover from lowell, MA10/23/2012
this product is great if its a begging flea problem, you dont have to do the entire mambo dance with bombs and all.
entirely pets had the best price, my vet had it at 100% markup, and shopping around Entirely pets had the best price. I am pleased with the purchase.
Really effective product by kenl from So Calif06/05/2012
Really effective in this mostly carpeted 3 indoor cat household. Fast knockdown 1st time used it 2 years ago. Now easy maintenance fleas don't have a chance to overwhelm us even in hot humid weather.
Awesome! by dwildwoman11/08/2012
This was an easy quick solution to getting rid of fleas on my cats. It was also inexpensive and worked great!
This spray always works and i've never had to treat more than once. You have to treat entire house. Even under beds and behind furniture. very good product for the money. I used to pay 35$ a can from the vet so this is a good price,too.
AMAZING PRODUCT! by LORI06/16/2010
First noticed my dog scratching..Then I noticed tiny,tiny fleas on my carpet.I wanted to jump out of my skin. My dog is an indoor dog goes outside on a 30 feet lead...Well i live in the country and he got fleas .. Maybe a woodchuck, rabbit, deer.. Well anyway I sprayed this product on my carpet. And within minutes, and I mean MINUTES..The fleas were gone. No more jumping.I am ordering 2 more cans to keep on hand.You won't be disappointed w/ this product..Sells at my local vet for $20.00
Siphotrol Spray really works by Janis from Savannah, GA05/31/2012
My grandson's room was covered in fleas. We had used everything we could think of. I ordered Siphotrol Spray, sprayed the room and within 20 mins. No fleas. I retreated 2 days later just to make sure they were gone. I am getting ready to order another can to have on hand just in case we need it. Great product.

Only flea effective product I'd use on my home by Mary from Cement City Mi08/20/2012
Siphotrol is the best flea spray for your home that I've found. Kills all stages. It has been a horrible year for fleas, nothing else worked. Getting ready to order more.
Vet-Kem Siphotrol II Premise Spray by postalwoman1 from Sacramento, CA11/26/2011
Excellent product! I have been using it for over 10 years and am so happy to have found a product that finally, really works! Instructions on can are not too clear, so I called the company. You need to leave the room for one hour but this is one amazing product. Works great for rooms that are not too cluttered.
fleas dont like it by Luv2dogs from southern California10/22/2012

Best Flea Product by 3 Cats & a Dog from East Central Georgia05/26/2012
I've used Siphotrol products for years and I've not found anything that works better for area treatment. It's easy to apply and works thoroughly and quickly. It's once and done!
Have tried Zodiac spray treatment when I couldn't find Siphotrol locally - there's no comparison. Spray with Siphotrol and be done with fleas!

Fleas be gone by Ladyhawk from Southern Illinois07/09/2012
It was fantastic! Of all the products that I tried to use to rid the house of fleas, The adams fleas spray knocked them right out.
Excellent flea spray by Laudvette from South Florida05/23/2013
No matter how clean your house or your pet is, those little nasties jump on them outside or from plants. This product is what we have always used to make sure our house is flea and tick free. It works just fine.
Decent stuff by flea magnet from new england10/14/2011
Seems to do the job well enough and for a pretty good price. Unfortunately when you have an infestation, you're going to need to buy a bunch of these. Even when you think the fleas are gone, a new batch hatches and the fight is on again.
It works, it's affordable. by Littlebit55 from Maryland10/23/2012
Hi, I've used this product before and really liked it. This year my local stores didn't have it so I purchased something else that didn't work near as well and was more expensive. I found it on this site, the price was affordable, the product works great. Follow the directions carefully, to insure the health of your pets etc. I will continue to keep this on hand to prevent flea problems.
YES!!! You want this! by ME from Lothian, MD05/11/2013
We have been battling fleas for about three years now. We used the Adams Carpet Spray with the new Seresto Collars and got rid of the fleas in two weeks. It's Great!
Flea Problems by Si from Havertown Pa11/02/2011

AMAZING PRODUCT by lindas from Los Angeles, CA06/19/2012
I was looking for something to spray on the outside because my little dog was being eaten up with fleas every time I took him out in the back yard. I checked with Amazon.com and I saw this listed and because I was ordering several products, they added shipping on each item, so I decided to check your website and I was amazed that it was a flat rate for shipping all the items. I saved $8.00 on shipping alone and I have turned my daughter onto this company. The product was easy to use and I will be reordering again.
What a relief!!! by Debbie03/18/2009
I have a Jack Russel who suffers from flea bite allergy. being that I also have another dog and 3 cats controlling fleas is a constant effort. since using this stuff my Mitzi no longer has flea bites. what a relief. I have a big yard and use once a month.
clean up was a lot easier than other foggers I have used.
disappointing by laura11/06/2012
used one on every floor.followed directions, there was less fleas seen , but still had a noticable amount!!!
Very disappointed by Cat Lady from Maryland11/06/2012
I have used this product before and always had good results, but not this time. I still have fleas! I even used the premise spray as a back up. Not sure what happened or why but I'll be wary to try again...

THE ONLY HOUSE FOGGER WE'VE USED SINCE 1983!!! by GW3 from TALLAHASSEE, FL04/13/2012
THE FIRST TIME WE USED YOUR HOUSE FOGGER WAS WHEN WE MOVED INTO AN APARTMENT IN 1983. A RUG WE HAD HAD IN STORAGE TURNED OUT TO BE INFESTED WITH FLEAS. IT WAS AWFUL!
OUR VET RECOMMENDED SIPHOTROL. IT WAS WONDERFUL. NO FILM ALL OVER OUR STUFF, LIKE BRANDS WE'D TRIED BEFORE. BEST OF ALL NO ODOR! JUST TWO SHORT HOURS AWAY, AND AIR THE HOUSE OUT FOR ONE HOUR AFTERWARD AND YOU'RE GOOD TO GO. USED IT EVER SINCE!!
gets rid of fleas by S Murcko09/05/2009
Siphotrol is the only flea fogger that I have tried that really works. If your infestation is very bad, you may need to repeat, but this product will get rid of the problem.
BEST FOGGER EVER by MAL05/07/2013
I HAVE BEEN USING SINCE 1989. MY VET RECOMMENDED IT. EASY TO PREPARE, LEAVES NO SCENT BEHIND!
Poor Service by Moi10/23/2012
We ordered this fogger as well as other products. The siphotrol was on back order. After 2 weeks I emailed to cancel the order, and then miraculously it was in stock 10 minutes later. I would recommend ordering from a company that is more organized.
Killed the fleas by Littlebit55 from Maryland10/23/2012
Hi, I have a multi pet family . I have mine plus I inherited my parents after they passed away. This year was the worse for fleas in a years. I sprayed, I bathed, etc. etc. Finally I though I am going to have use bombs.
I picked this based on other users ratings. My flea problem was eliminated. Use the appropriate amount for the space you need to cover.Make sure you remove all pets from the area, and take all other precautions. After using the bombs, I made sure I bathed all my animals before putting back in the treated areas, and placed a topical , or sprayed my pets . No more fleas. I will definately use these again for fleas if I need a bomb. These also did not have an overpowering odor like others I have used.
Recommended! by WA-fleas from eastern washington01/10/2013
Worked like a charm! bought this and the Knockout Spray + a flea bath and now there are no more fleas on any of our 5 adult cats or 4 kittens. Am much happier with these products then I was with the Frontline Flea protection since they all got infested while on it.

My bull terrier, Billie, managed to have a flea take a ride on her into my home, Did everything I possibly could, OTC foggers, carpet powders, sprays on her and in the house, washed everything, bathed her time and time again, "frontlined" her....vacumned every day, etc...

Danger by Dunker81703/11/2013
This product was recommended by my vet but after reading the warning labels I decided to not use it. It's highly flammable (my home is natural gas with pilot lights) and the fumes are toxic. There are much easier ways to rid your home of fleas. The risk of fire and poisoning was too great and too many precautions needed.
by from 12/13/2011
My indoor dog got some fleas and I used this product to proactively treat areas where the dog frequents even though I saw no evidence of fleas other than on the dog which were treated topically.

Greatest & Easiest by postalwoman1 from Sacramento, CA12/16/2011
This product should be on every shelf where pet products are sold! Unfortunately, they have to have a Licensed Vet on Payroll to sell it... Ask your Vet, he/she will tell you it is great! You can even use it in a cluttered room! Works the 1st time and good directions on label.
This is an excellent product and helped conquer my flea problem last year. I have used this before in another residence. Use it lightly and only on the day you intend to dust and polish. The powder gets everywhere but it works great. If applied to heavily, it will clog your vacuum.
Excellent,effective produce from a great seller by HRSpain from Spain12/03/2012
Can't fault the product and the service from EntirelyPets was perfect. Thanks.
