How Long Can Lice Live without Host?

Q:
How long can lice live without host?

A:
The head lice life cycle lasts about 45 days. Away from someone’s head (on furniture, carpets, clothing, bedding, etc) head lice can live up to 2 days. This is true for nymphs and adult lice. However, nits can live up to 9 days away from a host (until they hatch).

Head lice can live up to 48 hours in clothing. After this time, they die because they cannot feed on human blood.
