  YOU HAVE TO GET THIS!

  If you have a flea infestation, you NEED to get this. We tried nearly EVERYTHING for our flea problem and this is the only thing that worked.Our German Shepherd brought fleas into our home during the late summer. I didn't even realize the poor thing had fleas until I was scratching her one day and noticed a bite on her leg. I rolled her over to inspect her body and saw two fleas on her stomach. I let my husband know and after discussing it, we decided to try and treat the house with what we had. After all, it wasn't THAT bad. I had only found maybe ten on her, so we don't need to do much to get rid of them, right? WRONG!We used 91% rubbing alcohol in a bottle with a few drops of dish soap and sprayed down the entire house-every crack and crevice. We vacuumed thoroughly and I combed out our dog with a flea comb everyday. We used Eucalyptus, Lemongrass, and Cedarwood oil on her. Honestly, all of those things were STUPID ideas because they DIDN'T WORK AT ALL. In fact, it seemed like it made the problem worse!So, once the "natural" remedies failed, we picked up a flea carpet powder and bed bug spray. The bed bug spray was recommended for flea problems by the lady who worked at our local hardware store. We sprayed down the entire house and endured this HORRIBLE bed bug spray that made our eyes water, made us sneeze like crazy, and generally made us feel like we had insane allergies DESPITE properly ventilating and wearing masks. So, after all of that nonsense, we waited. The next day? Fleas. Everywhere. THANKS FOR NOTHING, HARDWARE STORE LADY!After that didn't work, we vowed to do thorough research on what we needed to get rid of these pesky little suckers. Not even a week later, we finally decided on Virbac. By then, the flea infestation had gotten SO much worse. I never realized just how fast these things reproduce and wreak havoc on your home, your pet, and your family. It was HORRIBLE, but we were absolutely DETERMINED to get rid of them.I anxiously waited for the Virbac to arrive in the mail. While waiting, my husband and I created a game plan. We would first treat the yard with Nematodes-yes, NEMATODES. We used30 Million Live Beneficial Nematodes Hb+Sc+Sf - Kills Over 200 Different Species of Soil Dwelling and Wood Boring Insects.. Next, we would go to the vet and get a six-month supply for flea prevention for our dog. After that, I gave her an EXTREMELY THOROUGH bath. I spent at least 45 minutes in the bathroom, scrubbing every single inch of her with my fingernails. I used Dawn Dish Soap and water-that's it. I scrubbed and scrubbed, from her neck to her tail. I put a "necklace" of dish soap around her neck to prevent any fleas from trying to escape to her dry head. I then combed out her head with the flea comb afterward. The bath was VERY tedious and I was meticulous about getting every single one of those stupid fleas. When she was finished, I dried her off and went through every inch of her coat with a flea comb.Once I was sure she was flea free, we vacuumed the house from top to bottom. After our dog dried off, we put her outside while my husband sprayed the house with Virbac. During that time, I took my children to the movies so they weren't subjected to the chemicals in the spray. Once he finished spraying the house, he waited an hour, and vacuumed again.The next day, there were NO FLEAS. A week later, I found a few in the house, but they weren't jumping. They were lethargic, just crawling along the carpet. The bottle does say that you may see adult fleas for up to two weeks after spraying, but to rest assured that it will NOT turn into an infestation. They were right. We just kept vacuuming to make sure and suck up any of the newly hatched fleas.After that, I never saw a flea again. Not in my carpet (even after crawling around on my hands and knees and LOOKING for these suckers-I was paranoid! I HATE FLEAS!). Not on our dog. Not in the yard. Nowhere. I am SO thankful for this product and now we know, if we see a flea, we're getting Virbac.Quick Note: After reading through some of these reviews, I have to stress this: YOU HAVE TO TREAT EVERYTHING! You can't just spray your house with Virbac and expect the fleas to magically disappear. They're still going to be on your pet and they're still going to be in your yard. These little suckers are resilient and their eggs are damn near impenetrable. Virbac works great in the home because it has an IGR and prevents reproduction. However, you still have to treat your pet(s) and your yard! Virbac will only treat your home. You need something for the yard, whether it's nematodes, a flea spray, or a professional exterminator, and you need a flea prevention medication for your pet.

  TERRIFIC PIECE!!! WORKS QUITE EXCELLENT!!!

  Fleas were really bad last year and I bought this. I sprayed it around my house after seeing a couple of fleas. Never saw another flea again. My vet recommended it. I bought an extra just in case but it sits in my closet. Amazing stuff!!

  Performs excellent, but do not consider it a total eradicator of fleas.

  Fleas are touch bastards to get rid of, especially as they lay hundreds of eggs per day after feeding. This is the 2nd time I have used this stuff, prior was in a previous residence. It really does help to kill flea and tick infestations. HOWEVER; keep in mind that this is not a spray and done. While it does kill the fleas and their larva it doesn't kill the eggs. Because they are protected. It does however contain IGR which inhibits the growth so fleas do not reach their full size biting potential. Be sure to test a small corner area or somewhere out of view to ensure no staining occurs on your carpet. The best method that worked for me was that I sprayed the carpet, as well as my cloth sofa, and the dog bedding area. I lifted up the cushions on the sofa and sprayed those. I also lifted the couch and dog bedding and sprayed under that as well as the carpet that it was residing over.I then ALSO used RAID Fumigator bug bombs. Note: Fumigator and not Fogger. The Fumigator requires to be placed into water inside the plastic containers it comes with. This allows a thicker heavier fog as opposed to the compressed can "Foggers" they sell. I have used both before and watched through the window that the fumigators do a better job, they also cost more.I left my house for 4 hours with the dogs and went to a dog park. This allowed ample time for it to work. Upon arriving home I opened the screened windows to allow it to air our for 20 minutes before bringing the dog's back inside. During this time I bathed them outside with Adam's flea and tick shampoo. I started with placing a ring of shampoo around their neck at the base of the skull. This will prevent fleas from trying to climb up their back and onto their head to "hide" while you're shampooing them. People are quick to shampoo and rinse off their dogs but the shampoo should sit for 5 minutes. After shampooing then VERY thoroughly (make sure you get the paws and inside the toes) I then blow dried them and fed them the flea/tick pills I purchased from my Vet.I then went inside and vacuumed the floor (as this vibration awakens the eggs causing them to hatch and also sucks up fleas hatching) and sprayed the Knockout spray again to kill any active fleas that might have hatched and missed the vacuum. I have a Dyson DC50 so I rinsed the vacuum filter with soap and hot water and sprayed inside the cyclone canister with the Knockout spray. I then took the dogs for an hour drive as they love car rides and because I needed the Knockout spray to dry out.Since then they have no longer had fleas and my arms and legs are no longer getting attacked. 1 Can worked for me and I have a 1 bedroom apartment that's entirely in carpet (aside from kitchen and bathroom). So depending on the size of your carpet area, you may need 2 or more cans.
