The first time most people hear the word lice, it’s usually followed by instant panic.
Maybe your child came home scratching their head, or you felt an itchy scalp and started Googling at midnight, zooming into blurry photos online.
The confusion is real — lice are tiny, fast, and easy to miss if you don’t know exactly what you’re looking for.
Quick Answer:
Lice are tiny, wingless insects about the size of a sesame seed. They are tan, gray, or brown, crawl quickly through hair, and live close to the scalp where they feed on blood.
🧠 What Does Lice Look Like?
Lice are very small parasitic insects that live on the human scalp. Adult lice are usually 2–4 mm long, making them hard to spot with the naked eye.
Here’s what they typically look like:
- Flat, oval-shaped bodies
- Six tiny legs with claw-like grips
- Tan, grayish-white, or brown color
- No wings and cannot jump or fly
Lice move fast, especially when exposed to light, which is why people often miss them during quick checks.
In short:
Lice = tiny crawling insects = sesame-seed sized bugs living near the scalp
📱 Where Is Lice Most Commonly Found?
Lice don’t live everywhere on the body — they prefer specific warm areas.
Most common places:
- 🧠 Scalp (especially behind ears)
- 🧵 Hair near the neckline
- 👂 Behind the ears
- 🪮 Close to the roots, not the hair tips
Important notes:
- Lice do not live on pillows or furniture long-term
- They survive best on human heads
- They spread through direct head-to-head contact
Lice infestations are common, not dirty, and mostly affect children.
💬 What Do Lice Eggs (Nits) Look Like?
Many people confuse lice with nits, but they are different.
Nits (lice eggs):
- Oval-shaped and extremely small
- Yellow, white, or tan in color
- Firmly attached to hair shafts
- Located close to the scalp
- Do not flake off like dandruff
Nits are often mistaken for dandruff — but dandruff slides easily, while nits stay stuck.
🕓 When to Check for Lice and When Not to Panic
✅ When to Check:
- Persistent scalp itching
- Red bumps or sores on scalp
- Tickling feeling in hair
- Known exposure at school or daycare
❌ When Not to Panic:
- Mild itching only
- Dry scalp flakes
- No visible bugs or nits after thorough checking
