After discovering lice in your home, you need to clean every room to prevent further infestation. Lice may live as long as three days off of the body, while nits can live for as long as three weeks, according to Children’s Healthcare of Atlanta. Clean after all family members have been treated with a topical lice medication and nits have been removed with a fine-tooth comb. Although it is important to clean your child’s room, the University of California does not recommend applying an insecticide to objects.
