I'm a bit late with this answer, wish i got to you before you used all those chemicals! but i'll still say it incase you ever have to do this again, flea treatment has come a long way... and i've seen hundreds of families with bad cases of fleas get rid of them without any "bombing" or exterminators. We don't recommend those anymore, we actually recommend avoiding them :(
So if it ever happens to you again, consider using only a good prescription topical treatment on the cat (NOT an over-the-counter one because i've seen cats get very sick from those and they rarely work, but one from your vet like Advantage or Revolution)...
I've worked at a cat-only hospital for 9 years, and the topical treatment will maybe cost around $100 for 3 months of treatment. Nice thing is these are really safe & companies stand behind their products with a guarantee that they'll work (but only if you buy from a vet, not if you buy online, because they don't sell directly to petmeds or any of those other online pharmacies, that's shady stuff & a whole other story!).
When your cat has this treatment on board, they become a "walking flea bomb" around the home... as the fleas hatch they jump on the cat to feed and die before they can lay more eggs, stopping the cycle until they're all gone! It can take a few months for flea eggs to hatch though, so that's why you need at least 3 monthly treatments for each pet. I've never seen it not work!
It always makes me cringe to see people use all those chemicals in their home around their children and pets when there's such an easier, safer way. Hope things clear up for you soon!!
