How can lice be eradicated in an apartment? - briefly
Wash all clothing, bedding, and washable fabrics at 60 °C or seal them in airtight bags for two weeks, then apply an FDA‑approved pediculicide to all residents and thoroughly vacuum carpets, upholstery, and cracks, discarding the vacuum bag afterward. Repeat the cleaning and treatment after seven days to eliminate newly hatched nymphs.
How can lice be eradicated in an apartment? - in detail
Effective removal of head‑lice infestations in a dwelling requires a systematic approach that combines personal treatment, thorough cleaning of the environment, and ongoing monitoring.
First, treat all affected individuals. Apply a pediculicide approved by health authorities according to the product label, ensuring coverage of the scalp and hair for the recommended duration. Repeat the application after 7–10 days to target any newly hatched nymphs that survived the initial dose. Use a fine‑toothed comb on wet hair to remove live insects and eggs; repeat combing every 2–3 days for two weeks.
Second, isolate personal items that cannot be washed. Seal clothing, bedding, hats, scarves, and hair accessories in airtight plastic bags for at least 48 hours; lice cannot survive without a host beyond this period. For washable items, use hot water (≥ 130 °F/54 °C) and a high‑heat dryer cycle for at least 20 minutes. Non‑washable fabrics may be dry‑cleaned or placed in a freezer at –20 °C (–4 °F) for 24 hours.
Third, address the living space. Vacuum carpets, upholstered furniture, and floor mats thoroughly; discard the vacuum bag or empty the canister into a sealed bag and discard it immediately. Steam‑cleaning surfaces with temperatures above 130 °F can kill residual insects and eggs. Wash curtains and drapes in hot water or replace them if cleaning is impractical.
Fourth, treat personal grooming tools. Soak combs, brushes, and hair clips in hot water (≥ 130 °F) for 10 minutes, then dry them with a clean towel or place them in a sealed bag for 48 hours.
Fifth, implement preventive measures. Encourage regular scalp inspections, especially in children, and avoid sharing personal items such as hats, hair ties, or headphones. Maintain a routine of washing bedding weekly during the eradication period.
Finally, schedule a follow‑up inspection after two weeks. Verify the absence of live lice and nits on all individuals. If any signs reappear, repeat the treatment cycle promptly. Continuous vigilance for an additional month reduces the likelihood of recurrence.
