Instructions

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.

  • Useful tool in our doxie flea-fighting kit

    By on Top 100 Contributor

    We've been spraying this EVERYWHERE (carpet, furniture, bedding) each week after vacuuming, in an attempt to keep the fleas on our three dachshunds under control. Our home seems to remain flea-free but our dogs are another story... I'm beginning to wonder if anything can keep the TX fleas in check! I'm a bit wary of the harsh chemical smell (which irritates my chest a bit) but I quickly vacate the area after spraying and don't notice it two hours later. This product is easy to use, but, once the can's down to about a quarter full it stops spraying so effectively and you get wet blobs of foam coming out (I guess the aerosol runs out before the product?).

  • Worked better than I could have hoped for

    By on

    We had a really really bad year with fleas in my area. Basically anyone I knew or heard of with pets had fleas, And I tried everything. I bought this after reading reviews thinking at this point what do I have to lose, and it's low cost. Sprayed the basement which is where ground zero was and in less than a week the numbers dropped drastically and by the end of the week they were all gone. All. Of. the. them. These little guys are attracted to me like crazy and I could take one step down there and they would just cover my legs. Nothing. I stopped seeing them upstairs, no more in the vacuum. The animals were all clear. Well worth the money. We are buying a few more cans for the upcoming season We had a really really bad year with fleas in my area.

We are buying a few more cans for the upcoming season because it was so nice not seeing these demons in my house and I will make sure they are out this year. If you have tried almost everything you can think of, buy a few cans of this, follow the instructions and spray away. Seriously. You will be glad you did. … more

  • Not a total knockout but a good second step

    By on

    Because it is harmful when wet I've had to go one room at a time to move animals around (who don't know each other by the way). Each animal was given expensive Advantage Plus or Revolution but I've learned dogs need Sentinel so that flea larva become sterile. Still working on the rooms. Wore plastic bags on my feet and a mask just to be safe. Vacuumed after I felt dead bodies would be present. And I've vacuumed again with a Rainbow vacuum. Know some product has to be used, but still seeing adult fleas on cats that I'm combing out. Feel I'll be doing a second spray. Carpet and furniture the culprits when the animals have been treated. So ordered a second can.

    Used this on areas where our cats spend most of their time, in their bedding, towers, etc. It seems to have slowed the scratching down somewhat; if I can find a decent flea preventative to work with this spray, will have things under control. Although the smell is very strong, it dried quickly and didn't stain the carpet, bedding or drapes.

  • Best Ever!

    Tried everything. Nothing worked. Put my dogs on Nexgard and cats on Frontline Gold. Sprayed whole house with this product and fleas were gone immediately.

  • It works great

    By on

    I have a flea infestation that went un-noticed by vet. I am using this to control eggs and adult fleas in all areas of my house. It is doing very well at keeping them from multiplying. Also using vets best to spray dog and cat. Fogging whole house, +vets best flea shampoo + vets best spray. Will return with results.

  • Got rid of the ones in the house, epicenter is still infested

    By on

    I have a room I rarely go in. This room has become a breeding ground for fleas. They're in the rest of the house, but not like in this room. 30 fleas on your legs as soon as you walk in. Anyway I treated all of the house with this product and it got rid of the fleas that made it out of the room. Treated the heck out of the room too, but no luck. I think I need an exterminator for that one. Overall good product, kept the fleas out of the rest of my house. Would definitely use it again for a minor infestation.
