NYTimes ran a great article on this, but it might be subscriber-only.

Here are some highlights:
-anything that will suffocate the lice is great - olive oil, mayo, hair conditioner, or any other mild lotion. You put it on the child's head, heat with a hair dryer, cover in plastic and leave over night. wash out in the morning or at least 8 hours later. repeat at least once a week for 2-3 weeks.
-comb your child's hair and pick nits every.single.day. (you'd have to do this with the pesticide route, too....)
-wash bed linens in hot water and dry at high heat for 20 minutes to kill any runaway lice
-throw stuffed animals, pillows, etc. that have come in contact with the infected person’s head in the drier
-vacuum thoroughly
