What is the lifespan of pubic lice?

Pubic lice (crabs) live about 3-4 weeks on a human host, feeding on blood, but die quickly off the body, usually within 24 to 48 hours, as they need human blood to survive. Their life cycle from egg (nit) to adult takes roughly 2-3 weeks, with eggs hatching in 6-10 days and nymphs maturing into adults in about 2-3 weeks after hatching, notes the CDC and Texas DSHS.
 

Can pubic lice live in your head hair?

No, pubic lice (crabs) generally do not live in head hair; they prefer coarser body hair like pubic hair, but can sometimes be found in armpit hair, beards, eyebrows, and eyelashes, and are a different species than head lice. While very rare infestations of head hair can occur, it's uncommon as pubic lice need the coarser texture of other body hair to thrive, and head lice are the primary parasite for scalp infestations.

No, you should not use a regular hair dryer to kill lice due to high burn risk and inefficiency; specialized hot-air devices (like LouseBuster) work by dehydrating lice, but a standard blow dryer lacks the controlled, consistent airflow needed and can spread lice, making it unsafe and ineffective for killing both lice and their eggs (nits). Professional heat treatments use controlled, high-volume airflow, not just heat, which is different from home blow dryers.
 

Do lice live in pillows?

No, lice don't live in pillows because they need human blood to survive and can only live off a scalp for about 1-2 days, but they can transfer to pillows and bedding, creating a small risk of reinfestation, especially if someone else uses the pillow within that short time. The main transmission is head-to-head contact, but you should still wash bedding in hot water or use a hot dryer to kill any stray lice or nits (eggs).
