I don't envy you,we used flea treatment on our cats at the recommended intervals as a preventative.Never had a problem until they were just about due a dose,I'd been to a friend's house who views flea treatment as only to be used if you have fleas.Cat had fleas,I am the equivalent of a Michelin starred restaurant for the things....Took us a good month and a small fortune to get rid of them. Don't forget to vac the people beds and if you have a fabric laundry basket then that too,not much help but the powders you can get in the uk for carpets etc seem to be pretty good. Good luck!
