    WIsh I could tell if you worked...

    Our kitties never go out, but somehow we started to see fleas. This product is amazing! It not only works immediately, it lasts for weeks.

    This works perfect.

    By on

    When you have tried everything with partial results, give this product a try and the problem is resolved. Note: once you figure the square footage of product needed, buy an extra can or two as you may end up spraying more than needed for your own assurance. I assure you, this product works perfect.

    Works good

    By on

    Works great when spraying on present bugs but definitely doesn't seem to be keeping the bugs away or killing any bugs that come into the area where the product was applied.

    Excellent when used with Capstar

    By on

    My mobile veterinarian accidentally unleashed fleas in my home. Now, if it looks like my cats are scratching, I give them a dose of Capstar each. (Not a poison like most flea meds.) The flea free effect of Capstar only lasts 24 hours, so you have to spray the house with Virbac right away (while the cats are locked in the bedroom or bathroom). It only takes about 30 seconds to spray down my entire living room. There is no odor, and it dries in about 20 minutes. Be aware that it will make linoleum VERY slippery, but it's fine after it dries. It hasn't damaged any fabrics. Once it dries, I let the cats out, then spray the bedroom. I spray it on the floors, on pillows, and the sofa -- My mobile veterinarian accidentally unleashed fleas in my home. Now, if it looks like my cats are scratching, I give them a dose of Capstar each.

This combination of tactics has been a godsend! No more fleas!! No more sick cats!! I will never use Advantage, etc., or bug bombs again. … more

    Recommended by my Vet

    By on

    Extremely effective for a flea infestation. I used it on carpeting exactly as directed. The can says it covers 2,000+ square feet. I barely got three rooms treated when the can was empty after approximately 400 square feet.) I did order another can to finish the job. After two hours it's dry and you can vacuum. I continued to vacuum daily to remove any remaining fleas, eggs, etc. After about a week, no sign of the fleas. (I was also getting bites and that stopped, too.) Important...remember to also apply a flea treatment to all of your pets. I would recommend this product even though it's pricy. I only gave it a "4" instead of "5" because of the volume in the can.

    Traded one mess for another

    By on

    So far, this product seems to be helping, but the fleas are not totally gone yet. I'll do a second round of treatment in a week or so. However, even when following the directions on the can, this stuff comes out in big, wet blobs that create a giant mess. It's like spewing poisonous whipped cream everywhere. I have found no indication of what angle the can should be held at when spraying, but I was not able to get a consistent spray.

    ACTUALLY WORKS

    By on

    I have tried four different flea sprays before a friend recommended this one to me. We struggled with fleas for MONTHS. After so much guilt for my pets suffering, we tried this as a last ditch effort before we called in an exterminator. Worked after just ONE use. Took my pets to a friends for the weekend, sprayed half the bottle around the whole house, vacuumed, and we have never needed to spray again. HIGHLY RECOMMEND. You need this.
