Query: Does not get under furniture or boxes

This product is a mist, not a fog, and that means it only works if the flea is somewhere where the mist can land on it. If the flea is under furniture or boxes, it is safe from this. This product has slight variations on the name from the different sellers, but it works (actually it doesn't) the same. See my review the product did not work for me. See reviewKnockout IGR Flea Foggers 6 ozfor more details.TryRaid - Fumigator Fogger - 3 pack. It worked very well in my storage garage. Check your local hardware store, though, to get it faster. This product has to be shipped ground and takes a long time unless you are close.
