Directions:
  • For use only when building has been vacated by human beings and pets. Ventilate treated area for 30 minutes before re-entry. For best results treat all infested areas. Use one fogger for each 6,000 cubic feet (approximately 27 ft. x 27 ft. x 8 ft. ceiling) of unobstructed area. Use additional units for remote rooms or where the free flow of fog is not assured.
  • Preparations: Remove or cover exposed food, dishes, utensils, surfaces and food-handling equipment. Shut off fans and air conditioners. Put out all flames and lights. Close outside doors and windows. Remove pets and birds but leave pet's bedding as this is primary hiding place for fleas and must be treated for best results. Cover or remove fish tanks and bowls, Leave rugs, draperies, and upholstered furniture in place. This product will not harm furniture when used as directed. Open interior closet doors and cabinets or areas to be treated. Cover waxed furniture and wooden floors in the immediate areas surrounding the fogger. For more effective control of storage pets and cockroaches open all cupboards and drawers for better penetration of fog. Remove all infested foodstuffs and dispose of in outdoor trash. For flea and tick control, thoroughly vacuum all carpeting, upholstered furniture, along baseboards, under furniture and in closets. Put vacuum bag into a sack and dispose in outside trash,. Mop all hard floor surfaces.
  • To start fogging, shake fogger well before suing. Hold can at arms length with top of can pointing away from face and eyes. Push down on finger pad until it locks. This will start fogging action. Set canister in an upright position on a table stand, etc. (up to 30" in height in the center of the area) and place several thicknesses of newspaper under the canister to prevent marring of the surface. Treat the whole dwelling using multiple units in homes with more than one level and numerous rooms. Leave the building at once.
  • Do not re-enter building for two hours. After two hours open all outside doors and windows, turn on air conditioner and/or fans and let treated area air for 30 minutes before reoccupying. If additional units are used for remote rooms or where free flow of fog is not assured, increase airing-out time accordingly.

Rated 2 out of 5 by from 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.

Rated 1 out of 5 by from wasted effort 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. :(

Rated 1 out of 5 by from 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!!

Rated 5 out of 5 by from Fogger I don't know if it's just Texas,but, I haven't had very good results with any flee products. Or maybe the other dog owners just don't use anything, but, Tipsys goingto the vets in the am for a good flee bath and check up, she's really got red skin and constantly is licking her legs. my poor baby

Rated 1 out of 5 by from Didn't work for long. The fleas disappeared for a few days and now they're back. I am furious that I wasted my money on this product. Save yourself and buy something that works.

Rated 1 out of 5 by from STUNNED THE FLEAS I purchased Virbac Knock out Fogger because VET KEM was not available at 1-800-PetMeds. It stunned the fleas, but within a week the infestation was back. I did all the usual, washed the cats with flea shampoo, bombed the apartment, put advantage II on the cats, (all within 24 hours) but nothing worked. I have just ordered VET KEM on line through a different business, since that product has been tried and true.

do fleas live in registers or vents

Asked by: missy
Its possible, but more likely fleas would be found in carpets or rugs. A pest control company may be a good source for finding out if they live in vents or registers. Thanks for your question.

Will the Virbac Fogger reach all areas?

We have a finished attic, a finished basement, and our main floor. Will the Virbac Fogger reach all the areas? The square foot needed is correct. I am just unsure if it will reach all areas. Thanks.
