What experiences have you had with fleas in your house and what did you do to eradicate them?

I have fleas in my house. I have seen about 3 or 4 total over the last week. I was in denial at first, telling myself “that’s just dirt” or “that wasn’t a flea,” but combined with seeing them plus having bites on my legs, I am now sure it’s fleas (and having 3 cats is the method by which I have gotten the fleas in the house).

Fleas are what brought me to Fluther. 4 years ago, I had them, and also a newborn baby which really was an upsetting combination. I was frantic, and ended up using an exterminator, after trying bombs, sprays, powders, home remedies, etc. My situation then was a bit different, though, because I had wall to wall carpeting, which I no longer have (thanks to the fleas and not wanting a crawling baby on carpeting that had been sprayed with pesticides).

I know the question has been asked in similar fashion on Fluther before, but I know with new Jellies may come new experiences and new answers.

What experience have you had with fleas in your house and home? What did you do to eradicate them? What worked for you?
