Haven't had to deal with fleas for quite a while now. (Thank gawd! I'm allergic to the little nasties!) Way back when...get a good flea spray or bomb (pet safe) and spray or bomb -- then do it again two weeks later for the second hatching. Used to put moth crystals under rugs, under chair cushions and between box spring and mattress -- but not too much!!! or your body will burn. (Made that mistake ONCE in my youth and inexperience.)
