Our sons room was infested with fleas, if you stood in one spot about 10-15 would jump on you. My husband tried vacuuming them away but that didn't work. So we put down Borax and swept it into the carpet. It has been sitting there for 3 full days with no decrease in fleas. So last night we applied this product (the entire bottle in 1 room) over the borax and swept it in until it all disappeared. Today, about 17 hours later, there was only 1 flea. I couldn't be happier! One thing to watch out for is while sweeping it into the carpet a LOT of the product gets into the air and since you are not supposed to breath it in I left the room and returned a bit later to continue the job. I recommend this product!
The Flea and Tick carpet powder works very well, I have a large dog and medium size cat they spend most of there time in the house, but they DID NOT like the sent of the product although I did, so i say they just have to get use to it, it does the job and smells good (to me anyway).
