Using Borax to kill fleas?

[waterbear]

Boric acid is sold as a treatment to kill fleas in carpets and upolstery. My vet recommeded it and it works! He said it would be safe for use with my animals, probably safer than the insecticide based sprays made for treating carpets and furniture! Fogging was not an option for me because of my birds and marine fish! You just sprinkle it on heavily, work it in with a broom, let it sit for a week and then vacuum it up. It kill both the adults and destroys the eggs. My cat and 3 dogs all were on the treated carpets and suffered no ill effects. I bought the boric acid at the hardware store in a shaker container and it was labeled for killing fleas. I would use it again if I needed it!
BTW, it is NOT meant to be applied directly on your pets.

Edit: I use Frontline on all of my pets also. Also, in the link above given by Dawndenise it does state that borates are one of the least toxic pesticides available! I read the whole article several times and the one quote taken out of context above. The actual quote was not from the above article but was a quote that was included in the article from the University of Nebraska-Lincoln Cooperative Extension and the FULL quote reads (empahsis mine):

“Although boric
acid is relatively safe to humans and
other mammals, it can be harmful if
accidentally ingested and must be kept
away from food, children and pets.
Care must be taken not to breathe in
the dust when you apply it. Like other
dust formulations, it should be used
in places where it will not move
around.”
