1. Shave everything (and every body)
2. Ask the doctor for prescription shampoo. For lice, ours reluctantly gave us Lindane (sp). Smelled like Raid. He told us to use it very carefully.
3. Strip all beds; wash blankets, washable rugs, cushions, etc....
4. Wash enough clothes to get you through a couple of weeks. Dry them thoroughly...or better, buy new (different) clothes for everyone in your house and all of you go on a vacation to a clean hotel for about 2 weeks.
5. Put all pets outside...and leave them.
6. Have a reputable company come in and treat your home at least twice. That should not only kill the live ones, but the second treatment should get any that hatch. Since they need blood to survive, many would starve to death if everyone is out of the house.
Good luck and God bless!
