Clothing lice reside in seams, folds, and crevices of garments, particularly in wool, fur, or infrequently washed fabrics. They also infest bedding, carpets, and upholstered furniture where fibers accumulate.

Where can a clothing louse be found? - in detail

The clothing louse (Pediculus humanus corporis) inhabits environments that provide a stable supply of human‑worn fabric and protection from disturbance. Its presence is most common in the following settings:

  • Personal garments that are worn continuously, especially outer coats, jackets, and sweaters left on a person for extended periods.
  • Bed linens, pillowcases, and blankets in homes where occupants neglect regular laundering at high temperatures.
  • Upholstered furniture such as sofas, armchairs, and cushioned seats in private residences, hotels, and dormitories.
  • Carpets and floor coverings in rooms with infrequent cleaning, particularly in corners or under furniture where darkness and warmth persist.
  • Stored clothing in closets, trunks, or luggage that remains unopened for weeks or months, creating a stable micro‑habitat.
  • Public transport seating, airline seats, and train berths that experience high turnover of passengers and limited cleaning between trips.
  • Institutional environments including prisons, shelters, and nursing homes, where crowding and limited hygiene resources increase infestation risk.

The louse thrives in temperatures between 20 °C and 30 °C and relative humidity of 70 %–80 %. Dark, undisturbed fibers allow eggs (nits) to adhere securely, while adult insects feed on human blood through the fabric. Infestations often spread when contaminated items are transferred between locations, making thorough laundering, regular vacuuming, and prompt replacement of infested textiles essential for control.
