I have the same problem every Summer, every Year! They get in the carpet, funiture every where.......I used to use Frontline Plus, Advantix etc. even over the counter sprays both of their fur got fried/burned off or scratched off from all the chemicals I was using on them their hair was too soft/silky for such harsh stuff. The only way I finally got rid of them: Moved into a House with wooden floors, I give them 1 "Capstar" pill, bathe them with a gentle shampoo and feed them "Flea Free" Natural Food Supplement it's $22.95 for 32 ounces I found it @ one of the 3 Pet Stores that I frequently buy from.
I use it year round just in case? Besides it's also supposed to be good for them too? So far that combination is the only thing that seems to work.
I take them to the Dog Park every day so it also kills what ever they pick up from there too! The only other thing would be to Flea Bomb your House & Flea dip your Baby, but I think the Fleas just grow immune to the Topical medicines, I'm a firm beleiver that Natural is Better! Good Luck
