Head Lice Facts & FAQs 🐛

 

1. What are head lice?

Head lice are tiny, wingless insects that live exclusively on the human scalp and feed on human blood. They are roughly the size of a sesame seed and are usually pale gray or brown. Their movement and saliva cause the signature, intense itching that most families notice first.

 

2. How common are head lice?

They are incredibly common! In the United States, the CDC Estimates that roughly 6 to 12 million infestations occur every single year [1.1]. It is the second most common communicable condition in school-aged children, primarily affecting toddlers and kids between the ages of 3 and 11.

 

3. How do head lice spread?

Lice spread almost exclusively through direct head-to-head contact. This frequently happens during school play, sports, sleepovers, or family hugs.

• The Myth: Lice cannot jump, hop, or fly. They do not have hind legs or wings; they can only crawl.

• The Reality: While less common, they can occasionally spread by sharing personal items like hats, hairbrushes, hair ties, or pillows if used immediately after an infested person.

 

4. Do lice need a male louse to reproduce?

Yes, to successfully hatch a new generation, they must mate. While a mature female louse can technically lay eggs on her own, those eggs will remain unfertilized and will never hatch. However, a single fertilized female can lay up to 100 to 150 eggs (nits) in her lifetime, cementing them tightly to the hair shaft with a waterproof glue.

 

5. Why are nits so hard to get rid of?

The waterproof glue secreted by the female louse is structurally similar to human hair proteins, making it completely immune to ordinary water, regular shampoo, and basic brushing.
