How to get rid of household lice? - in detail
Eliminating lice from a residence requires a systematic approach that combines personal treatment, environmental cleaning, and preventive measures.
First, treat every infested person. Use a pediculicide approved by health authorities; follow label instructions for dosage and exposure time. After application, comb wet hair with a fine-toothed lice comb to remove nits. Repeat the combing process every 24 hours for at least seven days to catch newly hatched insects.
Second, decontaminate personal items. Place clothing, bedding, and fabrics that can withstand heat in a dryer on high temperature for at least 20 minutes. For items that cannot be dried, seal them in airtight plastic bags for two weeks, preventing any surviving lice from emerging. Wash all washable textiles in hot water (minimum 130 °F/54 °C) and dry on high heat.
Third, address the home environment. Vacuum carpets, rugs, upholstered furniture, and floor crevices thoroughly; discard the vacuum bag or empty the canister into a sealed bag immediately. Steam‑clean hard surfaces and upholstery, as steam at 212 °F (100 °C) kills lice and nits. Apply an EPA‑registered insecticide spray to cracks, baseboards, and other potential hiding spots, following safety guidelines.
Fourth, treat pets only if a veterinarian confirms infestation, as lice species are generally host‑specific. Do not use human lice treatments on animals.
Finally, implement prevention. Encourage regular hair checks, especially after group activities. Advise against sharing combs, hats, or pillows. Maintain a schedule of laundering and vacuuming to reduce the likelihood of re‑infestation.
By adhering to these steps—personal medication, thorough laundering, targeted environmental sanitation, and ongoing vigilance—household lice can be eradicated effectively.
