How to check a person for lice? - briefly
Inspect the scalp and hair with a fine‑toothed comb, concentrating on the nape, behind the ears, and crown, and look for live insects, nymphs, or brownish eggs attached to shafts. Conduct the check on a well‑lit surface, separating hair into small sections and using a magnifier if available.
How to check a person for lice? - in detail
Detecting head lice on a person requires a systematic approach, proper tools, and careful observation.
Begin by selecting a well‑lit, flat surface where the individual can sit comfortably. Use a fine‑toothed comb designed for lice detection, a bright handheld lamp or natural daylight, and a clean white towel or paper to collect any debris. If possible, wear disposable gloves to avoid cross‑contamination.
1. Separate the hair into sections. Start at the crown, the most common infestation zone, and work outward.
2. Secure each section with a clip or hair tie before combing.
3. Pass the comb through the hair from scalp to tips in a single, steady motion.
4. After each pass, wipe the comb on the white towel to expose any attached organisms.
5. Repeat the process three times per section to ensure thorough coverage.
What to identify:
- Live lice: small, tan‑brown insects, about the size of a sesame seed, with six legs.
- Nits (eggs): oval, firmly attached to hair shafts, typically 1–5 mm from the scalp. They appear white or yellowish and do not detach easily when the hair is brushed.
- Viable nits: those within 1 cm of the scalp, indicating recent laying; older nits farther away are less likely to hatch.
After the examination, collect any found lice or nits in a sealed container for confirmation, if needed. Clean the comb with hot, soapy water and disinfect the examination area. Advise the individual to wash clothing, bedding, and personal items in hot water (≥ 130 °F) and dry on high heat to eliminate any surviving stages.
Repeat the inspection after seven days, as newly hatched lice become detectable only after several days of growth. Continuous monitoring for two weeks ensures complete eradication.
