Virbac Knockout Room & Area Fogger:
Virbac Knockout Fogger
Knock out Fogger
Over the years, when it comes to the name Virbac, I am usually always assured that the product with this name on it will perform well and reliably. I have used one variation or another of their knockout environmental flea spray or fogger for years. Years ago before all of the recent topical flea/tick pesticides came out like front line and advantage, we were always taught at meetings and in veterinary school how important it was to treat the environment of flea or tick infested dogs, as most of the flea life cycle occurs in the environment on the pet's bedding, rugs, furniture, etc, rather than directly on the pet. . And while many of these more recent topical flea/tick pesticides say that they work on immature flea larvae and eggs, I have not always been impressed, and I have still found it more effective to continue to use environmental products like this, along with great products like advantage or front line in truly having a comprehensive and complete flea/tick program that truly works long term on many levels. When I was living in Florida back in the mid 1990's, I found products like Virbac's knockout fogger so valuable in not only helping control flea popluations in an area of the country where fleas can be a problem throughout the year, but also helping control other pests like ticks, cockroaches, spiders, ants and palmetto bugs in those sam areas. The inclusion of not only products that kill adult fleas quickly and directly in the environment, but also insect growth regulators that help sterilize fleas and their eggs for up to 7 or 8 months. , is a big plus when using this wonderful time and tested product. The only real drawback I have found with product they carry at 1800petmeds. is that I usually prefer flea/tick environmental sprays for the home, as opposed to foggers, which often lose their efficacy in distant corners of a room and/or from a considerable distance from where they are released into the home. . Even with this limitation, I give this product an overall rating of a 4, with an ease of use a 4.
I used this product, treated my dog and 2 cats with frontline and still have been seeing fleas on my animals. I don't know what else to do I clean my house from top to bottom constantly. I finally am having a pest control company come in to get rid of these annoying fleas.
We followed the directions to the hilt and used a total of 4 in my small house. I am having Orkin in on the 9th. I don't think they made a dent. :(
This product is worthless
Have a small 2 bedroom home and used 2 canisters. Also treated the animals the day before with flea meds. Had to turn off the gas to the home, unplug anything that runs (cycles on periodically, like the fridge...) We just killed all power to the house. Set off the canister and left for 4 hours (canister stated at least 2 hours...), ventilated the house when we got back and stayed out of it for another 2 hours. The very next day the dogs were scratching again and less than a week later the house was infested with baby fleas. WORTHLESS!!
Tried a can in each room 10 X 12. Didn't do anything.
Had to call in a pest service to spray.
