How to detect clothing lice? - briefly
Inspect garments closely, especially seams, cuffs, and underfolds, for tiny, elongated insects or their attached nits. Use a fine‑tooth comb or magnifying lens to confirm presence and distinguish lice from fabric debris.
How to detect clothing lice? - in detail
Detecting pediculosis on garments requires systematic observation and, when necessary, laboratory confirmation.
Visible indicators include tiny, oval bodies attached to seams, cuffs, or folds; translucent, wing‑less insects measuring 2–4 mm; and darkened spots where insects have been crushed. Tactile clues consist of a crawling sensation when the fabric is brushed against the skin or a slight itching after prolonged contact. A faint, musty odor may accompany heavy infestations.
Effective inspection follows a three‑step protocol:
- Conduct a thorough visual survey under a magnifying lens (10–20×) in a well‑lit area; focus on seams, pockets, and areas where fabric gathers.
- Apply transparent adhesive tape to suspect regions, press firmly, then examine the tape under a microscope for eggs (nits) or nymphs.
- Collect a small fabric sample, place it in a sealed container, and send it to a certified entomology laboratory for microscopic analysis; confirm presence of pediculid morphology and differentiate from other arthropods.
When an infestation is confirmed, immediate measures include washing affected items at 60 °C, drying on high heat for at least 30 minutes, and sealing unwashed garments in airtight bags for 72 hours to starve the parasites.
Regular monitoring of clothing, especially after travel, contact with infested individuals, or use of shared laundry facilities, reduces the risk of unnoticed spread.
