If you find fleas in your home, you need to act quickly.
Clean your home thoroughly! Sweep tile or wood floors, and vacuum carpets, rugs, and furniture. Spray carpets and upholstery.
Get your yard treated and convince your neighbors to do the same.
Since fleas like to hide in dark places, spray under furniture and in crevices. Consider fogging your house. Be prepared that this will be a long battle. Depending on the environmental temperature and humidity levels, the total life cycle of fleas can take anywhere from a couple of weeks to many months. So if you missed a couple of eggs or larvae hiding somewhere, you will have to start all over again. In order to prevent fleas, protect your pet at all times.
