How do you use dust for fighting lice? - briefly
Apply a fine, non‑toxic powder such as diatomaceous earth directly to the scalp, hair, and affected fabrics, leave it in place for several hours, then comb out the insects and wash the area. Repeat the process after 7–10 days to eradicate any newly hatched lice.
How do you use dust for fighting lice? - in detail
Dust‑based treatments rely on fine powders that damage the exoskeleton of lice or interfere with their respiration. Effective powders include diatomaceous earth, neem seed powder, and sulfur dust. Each product requires precise handling to achieve maximum efficacy while minimizing irritation to the scalp.
The procedure begins with selecting a pharmaceutical‑grade powder free of additives. Measure a small quantity—approximately one teaspoon for an adult head—and spread it evenly over a clean, dry towel. Comb the hair with a fine‑toothed lice comb, separating strands to expose the scalp. While the hair remains elevated, sprinkle the powder onto the roots, ensuring coverage from the crown to the nape. Gently massage the scalp for 30–60 seconds to embed the particles between the hair shafts and the skin.
After application, cover the head with a breathable cap or a clean shower cap for 30 minutes. During this period the powder adheres to the insects, causing desiccation or respiratory blockage. Remove the covering, then brush out excess dust with a soft brush or vacuum with a HEPA‑rated attachment. Wash the hair with a mild shampoo to eliminate residual particles, avoiding harsh detergents that could irritate the scalp.
Repeat the cycle after 7–10 days, targeting newly hatched lice before they mature. Maintain a clean environment by laundering bedding, clothing, and personal items in hot water (≥ 60 °C) and vacuuming carpets and upholstery. Store the powder in a sealed container, away from moisture, to preserve its potency.
Safety considerations:
- Conduct a patch test on a small skin area to check for allergic reactions.
- Avoid inhalation; wear a mask and work in a well‑ventilated space.
- Keep the powder away from children’s eyes and mucous membranes.
- Discontinue use if severe irritation or redness occurs, and consult a healthcare professional.
