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.

this is the best!
By shay on Sep 12, 2020
We have been using this product for a couple of weeks now to fight a nasty flea infestation that we didn't know we had until about a month ago when we saw them crawling on our kitten (four months after rescuing him from a filthy house)! So those suckers had some time to infest our apartment and had recently started biting me. After using this spray we have noticed a DRASTIC improvement and not nearly as many fleas within a few days. I will say that if you live in a smaller apartment like we do, or if you're using it in a small room that you are going to want to leave for a few hours with a fan on and the window open. The fumes aren't unbearable and not as bad as some sprays I have smelled, but We have been using this product for a couple of weeks now to fight a nasty flea infestation that we didn't know we had until about a month ago when we saw them crawling on our kitten (four months after rescuing him from a filthy house)!

Since we were so infested we still need to treat a couple more times within the next few months on ensure all fleas are gone. … more

Sprayed twice, fleas still present
By hb176049 on Sep 29, 2020
I have used this product in the past with good results. This time, however, I sprayed twice within 2 weeks as directed , ( I sprayed even more liberally the second time) with Virbac and still fleas would cling to my socks and pant legs! I then tried another brand of area flea treatment and it also had no effect on the fleas! Now I'm using homemade soapy water flea traps which are working as the traps are catching less and less fleas daily.

works pretty good.
By amber on Jul 17, 2020
This stuff works pretty good. I used bleach and pin sol on all the hard surface floors and sprayed this on the carpets. It doesn’t work if you just spray this you also have to vacuum and treat the pets and yard. I bought frontline plus for the cats and some yard spray and I can already see results.

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.

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

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!

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!

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).
