Important Information
Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

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.

Toxic fumes and didn't kill fleas
By SueF on Dec 1, 2019
Had a possum living in my garage for a while and when I finally chased him out, I had a major flea infestation. Dozens jumping on me when I set foot in the door. I considered a flea bomb but decided I didn't want the fumes going up into the attic spaces because I'm very sensitive to chemicals and didn't want my pets exposed to fumes. So I purchased this product thinking I could just spray the floor and the other areas in the garage without the risk of toxic fumes. Even with all of the doors and windows to the house closed I could still smell it inside the house from the garage! I kept the garage closed up for an entire day to give it a chance to work and then it took me about three days to completely Had a possum living in my garage for a while and when I finally chased him out, I had a major flea infestation. Dozens jumping on me when I set foot in the door.

So I purchased this product thinking I could just spray the floor and the other areas in the garage without the risk of toxic fumes. Even with all of the doors and windows to the house closed I could still smell it inside the house from the garage! I kept the garage closed up for an entire day to give it a chance to work and then it took me about three days to completely ventilate the garage to get the smell out of there. I had to wear a respirator mask when I went in there to open the windows! And after a week, there were still dozens of fleas jumping on me! So I think all this did was create a major inconvenience for me but not for the fleas. I then purchased Fleabusters RX which is a borate based product, a powder with no fumes at all. I spread it around all over the garage floor and went back out there in a couple of hours and instead of dozens of fleas jumping on me there were maybe a handful. Now after two days of letting it sit on the floor there are only one or two fleas when I go out there. So comparing the two products, I don't think the spray did much. Although I did see a few dead cockroaches out there after the spray. But that's not what I was going for! If anyone tells you this product can be used in the house, they're crazy. … more

This will knock FLEAS out! Great Product!
By topcat22 on Oct 12, 2019
I was skeptical to try because of the price but I had tried everything to kill fleas in my home! When I saw saw Virbac I thought ok why not...cheaper than an exterminator! I sprayed entire area and let it sit for 2 days to make sure I killed every flea, larvae and egg! Then I vacuumed! It was dead silent in my house.. no more fleas! Did this can actually do the job? I been wasting money on natural products, DE, even products that swear to kill fleas for 7 months. But none of them worked. I bought another can and repeated the job a week later just to make sure I got all the larvae and eggs! So far so good!! Make sure you treat animals at same time. Try this stuff you won’t be let down!

Flea Problem Solved
By Tony on Nov 7, 2019
We had a flea problem on our dogs for months. We tried everything, but nothing worked. Our vet told us that fleas have developed an immunity to many flea products including Frontline and most flea sprays. They recommended Virbac and it worked!

ZAP! and they're dead!
By Fish on Sep 6, 2019
I buy this every year right at fall when the fleas seem to be at their worst. I have 2 cats that are indoor outdoor and 4 that are indoor. The outdoor cats bring in fleas all summer and by fall they are terrible. I have one cat (Persian) that is indoor that fleas use as a box lunch. Knockout kills them dead and keep them under control. Then we get that first freeze and that's it until spring. Get some and use it. You and your pets will be glad.

Great stuff
By Spitfire19985 on Aug 26, 2019
We used it soon as it came in and let it dry then did it again the next day just to make sure I did it right and now we have no fleas. We also vacuum daily for 7 days just to make sure that we get the eggs and all stages of life (per out vet).

Worth every penny
By Catlady on Aug 27, 2019
It's not as cheap as home store sprays but it's far safer to use, use after discovering a flea problem or as a preventative. Decided to follow my vet's advice and I couldn't be happier with the results

This really works!
By FleaKiller on Sep 19, 2019
I tried 5 other products and this one worked! It worked over the expensive spray that is similar to professional products on the market!
