Ok first off you don't have to bag nothing. Human lice can't live off the head for more then 24 hours. So you don't have to bag stuffed animals and what not.
You don't need to spray for the chemicals do more harm then good and as said above they won't live long off the human head.
No need for the shampoo for it will cause more harm to the head and don't work. You can take plan old mayo and put it in the hair and wraped the head in a plastic bag or show cap over night or during the day. Then the eggs will suffacate and you can just wash and comb the hair. Ditch the combs for lice and just use your fingers to get all the eggs out. The bugs will be dead anbd will fall off during wash.
The eggs will be brown if they are dead and white if they arn't. Then ever other day do the mayo at night for about a week or so for they come back if not all dead every 7 days. Wash all bedding and vacum and toss the bag. My dd got it back in October and had it for a month off and on for we used the sprays and shampoos. I called my docot and this is all what they said. I even did internet reading on it. So good luck, don't buy anything but Mayo and don't bag your house up
