What about areas like tile floors or wood? Do they need to be treated?

It is not necessary to treat wood floorings, tiles, or other smooth surfaces, since flea eggs are most probably not able to survuve out in the open, where there is a lot of movement involved. Carpeted and upholstered areas are the main areas that should be targeted. However, we do encourage you to clean, and vacuum all floors to remove eggs that may have been shed by your pet. Pay more attention to areas underneathe furniture, in closets, or in the garage. Hidden, dark areas that are undisturbed can be a nesting area for fleas. Therefore, make sure when you treat your home, you treat all these targeted areas.
