How long do head lice live off the head?
One of the most common questions parents ask after discovering lice is whether the bugs can live on furniture, bedding, or around the house. Understanding how long head lice survive off the head can help reduce unnecessary worry and over-cleaning.
The Short Answer
Head lice generally survive only 1 to 2 days once they are off a human head.
According to the Centers for Disease Control and Prevention (CDC), head lice need frequent blood meals to survive. Without access to a human scalp, they quickly weaken and die.

What About Lice Eggs (Nits)?
Nits need the warmth and humidity of the scalp to hatch. When they fall off the head or are found on objects like pillows or furniture, they are very unlikely to survive.
The Mayo Clinic confirms that lice eggs found away from the scalp almost never hatch.

What This Means for Your Home
Because lice don’t live long off the head:
You don’t need to fumigate or spray your home
Normal cleaning is enough
Focus should stay on treating the hair and scalp, not the environment
Helpful steps include washing recently used bedding or hats and drying them on high heat. Beyond that, extensive cleaning isn’t necessary.
Clearing Up a Common Myth
Lice do not live in carpets, couches, or air vents. They spread almost entirely through direct head-to-head contact, not through homes or furniture.
