Just like with mattresses, lice can only live on any bedding—whether it's sheets, pillows, or comforters—for 1-2 days. Without a human scalp as a source for food (blood) for longer than 1-2 days, lice cannot survive.
How soon do symptoms appear after exposure? Some people may not have symptoms, particularly with the first infestation or when the infestation is light. It may take 4-6 weeks for itching to appear the first time a person has head lice.

For example, hats, scarves, pillow cases, bedding, clothing, and towels worn or used by the infested person in the 2-day period just before treatment is started can be machine washed and dried using the hot water and hot air cycles because lice and eggs are killed by exposure for 5 minutes to temperatures greater than ...
Look for lice crawling on the scalp where the hair is parted or on the hair shaft. The lice will be dark in color and the size of a poppyseed. Look for nits near hair follicle about ¼ inch from scalp. Nits (eggs) will be white or yellowish-brown.
If you suspect you may have lice, look for a pattern of red, raised bumps on your scalp, neck, or shoulders.

Lice cannot “fall” on pillows, sheets, stuffed animals, and other bedding unless the hair that they are attached to fall. But they can't live on these surfaces, or on hats, scarves, furniture, or carpet. They also can't live on pets or any other animals. Nits can't live without a human host.

Washing, soaking, or drying items at a temperature greater than 130°F can kill both head lice and nits.
Head lice are human parasites and require human blood to survive. They are not environmental pests so pesticide sprays for furniture and bedding are unnecessary. Vacuuming is the safest and best way to remove the lice or fallen hairs with attached eggs from upholstered furniture, rugs, stuffed animals and cars.
