how do you get lice

Head lice spread almost entirely from other people, not from dirt or “bugs in the air.”

Quick Scoop

• Lice are tiny insects that live on hair and feed on small amounts of blood from the scalp or skin.

• You get them by close contact with someone who already has lice or their eggs (nits).

• They do not come from being “dirty,” animals, or grass; they only live on humans.

Main ways you get head lice

Head lice are the common kind most people mean when they say “lice.”

• Direct head‑to‑head contact
  • Hugging, taking close selfies, leaning heads together to watch a video, whispering closely.

* Very common among kids at school, daycare, sleepovers, and sports.

• Sharing hair or head items
  • Combs, brushes, hair ties, hats, helmets, scarves, headphones, towels, and pillows used soon after an infested person.

* This is less common than direct contact but still possible.

• Contact with recently used soft surfaces
  • Lying on a bed, sofa, or stuffed toys that someone with lice just used can occasionally spread lice, because a few may still be alive for a day or two off the body.

Things that do not give you lice

• Not from pets (dogs, cats, etc. have their own species of lice).

• Not from soil, tall grass, or dirty floors.

• Not from “jumping” or “flying” lice; they can only crawl.

• Not because your hair or home is “unclean”; lice infest clean and dirty hair alike.

Other types: body and pubic lice

• Body lice
  • Live mostly in clothing seams and move to the skin to feed.

* Spread through close physical contact and sharing clothes or bedding, especially in crowded or very poor hygiene conditions (e.g., shelters, camps).

• Pubic lice (“crabs”)
  • Live in coarse hair in the pubic area and sometimes other body hair.

* Usually spread through sexual contact; rarely from infested bedding or towels.

Simple example

If a child with lice hugs their friend and their heads touch, some lice can crawl across in seconds and start an infestation on the friend’s head.

Quick prevention tips

• Avoid head‑to‑head contact with someone known to have lice.

• Don’t share brushes, hats, helmets, hair accessories, or pillows.

• Check the heads of close contacts if one family member has lice so you can treat everyone who needs it promptly.
