How should i disinfect my child's room if they had head lice? my child has head lice. how should i go about making sure that her environment is properly sanitized?

You : You need to vaccum well. Clean all hard surfaces. Clean all linen, clothing, towels, soft toys that she has been in contact with. You can put some items into large plastic bags, that are tied off. If you have a steamer that would work great. Good luck. It can be a lot of work. P.S. Sofas and big chairs are often the areas that don't get cleaned well enough.
