I would bath everyone in a flea and tick shampoo and then use a flea bomb in the house. If you have houseplants, be sure to cover them and ensure all food products, water and food dishes are stored away. After airing out the house, vacuum and then monitor. I think it's recommended to bomb again in two weeks and I'd probably either bathe the animals again or apply a flea preventor such as Frontline....Good luck!!
