I went back and reviewed your earlier post. There are only a couple
other things I can think of---is your carpet shampoo also treating your carpet
for fleas? If not, you should probably get a carpet shampoo that treats for
fleas. You should only have to do this about once a week for three
There is also a product called de flea that you can spray on your animals
and just rinse off. You can even spay your carpets and furniture---test a
small area to be sure it wont stain. It's not very toxic to the animals or
humans but it really kills fleas. You can get it at some Petco Stores or
online for $15-20.
Another thing that works is to sprinkle some 20 Mule Team Borax on your
carpets, leave it for a few hours and vacuum it up. Flea powder works
too. With the borax you should vacuum it up before you let your animals in
the area. Flea bombs do a good job but they are more toxic and you all
have to leave the house for at least 6 hours. The other problem is that
you can't use them near any pilot light such as gas stoves, water heaters or
furnaces because they can set your house on fire.
I have found this summer that the advantage I am using for my cats and dogs
is only lasting about 3 weeks per treatment before they start itching
again. However it is safe to use de flea with the other treatments.
Hope this helps.
