They can only actually live off of the head for up to 48 hours. It is not likely that they are living in your bedding but it can happen. If you have head lice you definitely need to vacuum your bed. You also need to wash your bedding on hot and dry them on high for 30 minutes. Your pillows and non living bed accessories need to be washed and dried, dried on high for 30 minutes, or put in a bag for 3-12 days. I say 3-12 days because of the life span of a louse off of the head and because it is highly unlikely for an egg to hatch off of the head but it can happen. So by some miracle, lol, the egg falls off of your head and it incubates for the full 7-10 days and then hatches, then it must feed within a few hours. So 12 days is overkill but you know it's good.
