Where do clothing lice live? - briefly
Clothing lice reside in the seams, folds, and creases of garments—particularly wool, fur, or synthetic fabrics—and may also infest bedding and personal accessories. They stay near the host’s skin, feeding on blood while avoiding light.
Where do clothing lice live? - in detail
Clothing lice, scientifically known as Pediculus humanus corporis, inhabit the fabric and accessories that remain in close contact with a human host. Their preferred micro‑habitats include:
- seams, folds, and cuffs of shirts, trousers, and undergarments
- waistbands, collars, and pockets where fabric is compressed
- bedding material such as sheets, blankets, and pillowcases that are not regularly laundered
- personal items that are worn or carried close to the body, including hats, scarves, and backpacks
These insects spend most of their life cycle on the garments themselves. Adult lice reside in the fibers, laying eggs (nits) firmly attached to the fabric near the base of hairs or threads. Nymphs emerge on the clothing and develop while remaining protected by the garment’s structure. Feeding occurs only when lice crawl onto the skin to obtain blood, typically for a few minutes at a time.
Environmental factors that support their presence are warmth, humidity, and limited access to clean laundering. Overcrowded living conditions, infrequent washing in hot water (≥ 60 °C), or drying at low temperatures facilitate infestation. In the absence of a host, lice can survive on clothing for several days to weeks, but prolonged separation from a human reduces their viability.
Effective control targets the habitat: regular washing of all clothing and bedding at high temperatures, thorough drying, and isolation of infested items. Repeated laundering eliminates nits and disrupts the life cycle, preventing re‑establishment on the host.
