Summarize this article:

While this may seem excessive, it's actually a vital part of removing fleas from your home. Since fleas lay eggs that may hatch after you've treated your pet, you need to remove the eggs and larvae that fall to the floor or on furniture. Vacuum every day for a few weeks to ensure that a new cycle of fleas won't trouble you.  Remember to throw the vacuum bag away in an outdoor dumpster or empty the bagless vacuum canister into the outdoor dumpster. If you leave the dirt in the vacuum bag or canister, the fleas can easily work their way back into your home.  Eggs and fleas can also get trapped in the fabric on couches, pet bedding and other upholstered furniture. Vacuum upholstery every day for a few weeks. Diatomaceous earth (DE) is a natural and safe alternative for killing fleas in your house. DE is similar in consistency to talcum powder.  It can be sprinkled on carpets, baseboards, and other places in your house. Let it sit for a few days and then vacuum it up. This type of insecticide will restrict the growth of fleas and eggs. Check that the product will kill fleas/eggs for up to 7 months. Strictly follow the instructions. Make sure to remove all pets from the area when you are applying this insecticide. Don't forget birds and other pets in cages. Be sure to also cover aquariums when using these products. Strip as much of the fabric off your couches, chairs, and bed as you can. Then, wash it in the hottest water your fabric will allow. This should kill fleas and their eggs. Gather up any clothes that may be lying around, especially piles of laundry. Fleas will nest in fabrics. Washing and drying on the hottest setting possible will kill fleas and eggs.

Summary:
Vacuum your house daily. Use diatomaceous earth in your house. Use a flea insecticide with a growth inhibitor. Wash bedding and upholstery in hot water.
