The house. That is the next step. You need to grab all the clothes that may have come in contact with hair (this means any hair that may have fallen into the clothing such as a clothes basket or anything that may have been worn such as a coat or sweater) and put them in a pile to be put into the dryer. This would mean clean clothes that have not been put away yet or even clothes in their drawers if you just aren't sure. I put mine through the hottest dryer cycle I could three times in a row to make sure any bugs that may have been on them were dead. Any eggs would hopefully be sucked out and perhaps the bug inside killed due to the heat. If you can leave clothes in their drawers for a two weeks you should be OK, if any nits hatch the nymphs will die from lack of heat and lack of food. I just felt safer tossing all our clothes in the dryer.
All beds need to get stripped. Wash everything. Dry in the dryer for 2 - 3 cycles. The heat is what gets them.
Vacuum the beds, every inch of the mattresses. After the first day you shouldn't need to vacuum the beds as long as you change the sheets and pillowcases each day.
Pillows. Stick them in the dryer for 3 cycles in a row. Really get them hot to kill any bugs and nits that may have worked their way in. After that be sure to put a new pillow case on the pillow each day for at least 2 weeks.
At first I put all stuffed animals and dolls in plastic bags for a few weeks. I don't think this needs to be done anymore. As long as you change the sheets on the beds everyday and wash, do a cream rinse combing, and nit-pick the hair every day (at least) you shouldn't need to bag the toys.
The couches and chairs. Vacuum vacuum vacuum. You're trying to get any bugs that may be crawling around and any hairs with nits on them. Get in all the crevices you can. I want to mention about going to a movie theater and sitting in one of those seats that someone you don't know and probably never saw before was in. Now, let us imagine them having a thriving community of lice in their hair. And a few of those hairs with nits fell off onto that seat. And a louse or two fell off and are wandering about on that seat back. Now, let us imagine you sitting in that seat. And leaning back and getting comfortable. Where is your hair? And how fast do lice crawl?
Vacuum the floors. Any smaller rugs on the floor? If you have wall to wall carpeting, SIGH, you must be diligent and vacuum every day. Everywhere. Vacuum the furniture and then the rugs every day.
The car. People forget about the car. Bugs and hair with nits on them fall off in the car. Vacuum the heck out of it. Put it in the sun with the windows rolled up for the whole day. Vacuum at the end of the day. Do this for several days in a row if possible.
Pets? Give them a bath. The lice will not live on your pets but they still may get stuck on their hair as little hitch-hikers only to fall off somewhere. Be sure to include their pet beds or whatever in your vacuuming endeavors.
Oh, and don't forget to curse alot and be generally pissed off that you had to waste all your time doing this. But, usually the first day is the worst and then after that things settle down. Using the cream rinse helps when you comb through the hair. The bugs don't get trapped between the teeth (view the movies I have on this site, you can see the lice trying to hide between the teeth of the comb). With the cream rinse you can trap small as well as larger lice. And the cream rinse seems to help soften the cement used to glue the nits to the hair. The cream rinse has the added bonus of being so much safer to use on your child.
