How to eliminate household lice? - in detail
Effective removal of lice from a residence requires a systematic approach that combines thorough cleaning, targeted treatment, and preventive measures.
Initial assessment identifies infestation sites. Examine bedding, upholstery, carpets, and personal items for live insects and nits. Use a fine‑tooth comb on hair and fabric to confirm presence.
Cleaning protocol:
- Wash all bedding, clothing, and washable fabrics in hot water (≥ 60 °C) and dry on high heat for at least 30 minutes.
- Vacuum carpets, rugs, and upholstered furniture repeatedly; discard vacuum bag or clean canister afterward.
- Seal non‑washable items in airtight plastic bags for two weeks to starve insects.
Chemical treatment options:
- Apply a pediculicide approved for domestic use to affected surfaces, following manufacturer instructions regarding concentration and exposure time.
- Use insect growth regulators (IGRs) such as hydroprene to interrupt life cycle; apply to cracks, crevices, and baseboards.
Natural alternatives:
- Sprinkle diatomaceous earth on carpets and upholstery; leave for 24 hours before vacuuming.
- Apply a mixture of equal parts tea tree oil and water to fabrics, allowing thorough drying.
Preventive actions:
- Maintain low indoor humidity (≤ 50 %) to create an unfavorable environment for lice development.
- Conduct regular inspections of bedding and clothing, especially after travel or contact with infested individuals.
- Implement a routine of washing and drying linens weekly.
Consistent execution of these steps eliminates the current infestation and reduces the risk of recurrence.
