How can a house be treated for lice and nits? - briefly
Clean all bedding, clothing, and washable fabrics in hot water (≥130 °F) and dry on high heat, then vacuum carpets, curtains, and furniture, disposing of the vacuum bag or cleaning the canister afterward. Apply an EPA‑approved residual insecticide spray to cracks, baseboards, and other infested surfaces, following label directions and ensuring adequate ventilation.
How can a house be treated for lice and nits? - in detail
A comprehensive approach combines personal treatment, thorough cleaning of household items, and environmental control.
Personal measures
- Apply an approved pediculicide to all affected individuals according to product directions.
- Use a fine‑tooth nit comb on wet hair after treatment; repeat combing every 2–3 days for two weeks.
- Wash all personal items (hats, scarves, hair accessories) in hot water (≥130 °F/54 °C) or place them in a sealed plastic bag for two weeks.
Textile handling
- Launder bedding, towels, and clothing at the highest safe temperature; dry on high heat for at least 20 minutes.
- For items that cannot be heated, seal them in airtight containers for a minimum of 48 hours, depriving lice of a viable environment.
- Vacuum mattresses, pillows, and upholstered furniture; discard vacuum bags or clean canisters immediately after use.
Surface decontamination
- Vacuum carpets, rugs, and floor mats thoroughly; focus on edges and under furniture.
- Steam‑clean hard surfaces, upholstery, and car seats; steam at ≥212 °F (100 °C) kills both lice and nits.
- Wipe non‑porous areas (door handles, light switches) with an alcohol‑based solution (≥70 % ethanol).
Environmental treatments
- Apply a registered insecticide spray labeled for indoor lice control to cracks, crevices, and baseboards; follow label safety instructions.
- Consider non‑chemical options such as diatomaceous earth applied lightly to floor edges; leave for 24 hours before vacuuming.
- Avoid foggers or “bug bombs,” which do not penetrate fabrics and may pose health risks.
Preventive actions
- Conduct weekly inspections of hair, especially after sleepovers or school events.
- Maintain a routine of washing linens and clothing weekly at high temperature.
- Educate household members about avoiding head‑to‑head contact and sharing personal items.
By integrating these steps, a residence can be cleared of lice and their eggs, minimizing the risk of reinfestation.
