What is the best way to kill body lice in clothing?

ClinicsJo Editorial Teamاقرأ بالعربية16 views

To kill body lice and their eggs (nits) in clothing, the best method is to wash infested clothing, bedding, and towels in hot water at a temperature of at least 54°C (130°F), and then dry them using the hot cycle of a clothes dryer. This process effectively eliminates the lice and nits. If washing is not possible, dry cleaning or sealing the items in an airtight plastic bag and storing them for at least two weeks can be used.

Why do body lice live in clothing?

Body lice are small parasitic insects that live and lay their eggs (nits) primarily on clothing and bedding, rather than directly on human skin. These parasites need to feed on human blood to survive and move onto the skin only when necessary for feeding. Body lice often spread among people who cannot bathe and wash their clothes regularly, especially in crowded conditions. They can be transmitted through direct physical contact with an infected person, or by coming into contact with clothing, bedding, or towels used by an infected person [1].

Effective steps to get rid of body lice in clothing

To eliminate body lice from clothing and personal items, the following steps must be followed precisely:

  • Washing in hot water: Wash all clothing, bedding, and towels used by the infected person using very hot water at a temperature of at least 54°C (130°F). This heat is sufficient to kill lice and nits [2].
  • Heat drying: After washing, dry the items in a clothes dryer using the hot cycle. The high heat in the dryer helps kill any lice or eggs that may have survived washing [2].
  • Dry cleaning or isolation: For clothing and items that cannot be washed or heat-dried, dry cleaning can be used. Alternatively, these items can be placed in an airtight plastic bag and stored for two weeks. Body lice will die if they cannot feed on blood for one to two days [2].
  • Regular cleaning: You must continue to wash clothing and bedding regularly, at least once a week, to maintain hygiene and prevent re-infestation [1].

The importance of personal hygiene in treating body lice

In addition to treating clothing, improving personal hygiene is the primary treatment for body lice. This includes regular bathing and changing into clean clothes at least once a week. In some cases, a doctor may recommend using lice-killing medication (pediculicides), but they are usually not necessary if personal hygiene is maintained and clothes are washed properly [2]. It is important to note that body lice can transmit diseases such as typhus and trench fever [1].

When to see a doctor?

If you are unsure about a body lice infestation, or if itching persists or skin sores appear due to scratching, it is important to consult a healthcare provider. Excessive scratching can lead to sores that may become infected with bacteria or fungi [1].
