I agree with a lot of what has already been said. You've got a good start on things. Maybe open some windows in your house to air out the smell from the spray. I would definitely wash the bedding in hot water. Vacuum at least once a day. Not only will it suck up as many of the fleas and eggs that it can, the vibrations will also cause the eggs that are attached to fibers to hatch. Spot treatments are good for your pet, just don't touch for a day or 2. But please don't use flea collars on your pet. What most people don't realize is that they are actually toxic to animals. My instructors in vet tech school always told us to discourage them as much as possible, and when I worked at an animal shelter, we cut them off as soon the animals came in the door.
