Where to check for lice presence? - briefly
Inspect the scalp, behind the ears, and at the nape of the neck, examining hair shafts and the base of the skull for live insects and nits. Also check clothing seams, hats, pillows, and bedding for signs of infestation.
Where to check for lice presence? - in detail
Inspecting for head lice requires systematic examination of specific regions and objects where the insects and their eggs are most likely to be found. The process begins with a visual and tactile assessment of the scalp and hair, followed by a review of personal items and the surrounding environment.
The primary zones to examine on a person include:
- The hairline at the forehead and temples.
- The area behind the ears, especially the inner surface.
- The nape of the neck and the lower scalp.
- The crown and any thick sections of hair where lice can hide.
- The sideburns and any hair covering the face or neck.
Use a fine‑tooth comb, preferably a lice‑comb with metal teeth spaced 0.2 mm apart. Comb the hair while it is damp, starting at the scalp and moving outward. After each pass, wipe the comb on a white tissue or cloth; live lice appear as small, grayish insects, while nits (eggs) are oval and attached firmly to hair shafts. A magnifying lens (10×) aids in distinguishing nits from dandruff.
In addition to the host, inspect items that maintain close contact:
- Hats, scarves, headbands, and hair accessories.
- Pillows, pillowcases, and mattress covers.
- Clothing that touches the head, such as caps or uniforms.
- Bedding and towels used within the last 48 hours.
For each object, shake it over a white surface or use a lint roller to capture any attached insects. Wash washable items in hot water (≥ 60 °C) and dry on high heat; non‑washable items can be sealed in a plastic bag for two weeks to starve the lice.
Document findings promptly. If live lice or viable nits are identified, initiate treatment and repeat the inspection after 7–10 days to confirm eradication. Regular monitoring of the outlined areas reduces the risk of reinfestation and ensures comprehensive control.
