How to treat a house for scabies mites? - in detail
Treating a dwelling infested with scabies mites requires a systematic approach that eliminates parasites from humans, pets, bedding, clothing, and the environment.
First, confirm that all occupants have received appropriate medical therapy. Prescription scabicidal creams or oral ivermectin must be applied according to a healthcare professional’s instructions, typically for two consecutive days. Without effective treatment of the hosts, environmental measures will have limited impact.
Second, isolate and launder all washable items. Use hot water (minimum 50 °C / 122 °F) and a high‑heat dryer cycle for at least 20 minutes. Items that cannot withstand heat should be sealed in heavy‑duty plastic bags for a minimum of 72 hours, the period during which mites cannot survive without a host.
Third, decontaminate non‑launderable surfaces. Apply a pyrethrin‑based or permethrin spray approved for indoor use to mattresses, upholstered furniture, carpets, and curtains. Follow label directions regarding concentration, contact time, and ventilation. For porous materials that cannot be treated, consider removal or professional disposal.
Fourth, address potential reservoirs in the home. Vacuum all floors, carpets, and upholstery thoroughly, then empty the vacuum canister or bag into a sealed container and discard it outside the residence. Pay special attention to cracks, crevices, and under furniture where mites may hide.
Fifth, implement a post‑treatment monitoring schedule. Re‑examine skin lesions after 7–10 days; repeat medical treatment if new burrows appear. Re‑vacuum and re‑clean high‑risk areas weekly for three weeks to ensure any surviving mites are removed.
Summary of essential steps:
- Administer prescribed scabicidal medication to every person and pet.
- Wash or seal all textiles at ≥50 °C or for ≥72 hours.
- Apply approved insecticide sprays to mattresses, carpets, and upholstery.
- Vacuum extensively; discard vacuum contents in sealed bags.
- Maintain weekly cleaning for three consecutive weeks; reassess clinical signs.
Following these actions in the prescribed order eradicates scabies mites from a residence and prevents reinfestation.
