Strip the mattress, wash all linens in water above 60 °C, and vacuum seams, carpets, and furniture thoroughly. Apply a licensed residual insecticide or steam treatment, encase the mattress, and inspect weekly for several weeks.
How to get rid of bed lice? - in detail
Bed lice infestations demand a systematic approach that combines immediate eradication with long‑term prevention.
First, confirm the presence of insects by inspecting seams, mattress edges, and headboards for live bugs, shed skins, or dark fecal spots. Use a bright flashlight and a magnifying lens for accuracy.
Next, strip all bedding, curtains, and clothing. Wash items in hot water (minimum 60 °C / 140 °F) and dry on high heat for at least 30 minutes. Items that cannot be laundered should be sealed in airtight plastic bags for two weeks to starve the pests.
Thoroughly vacuum mattresses, box springs, bed frames, and surrounding furniture. Pay special attention to cracks, crevices, and upholstered surfaces. After vacuuming, immediately discard the vacuum bag or empty the canister into a sealed container.
Apply an approved insecticide to the infested area. Choose products labeled for bed‑lice control, following label instructions regarding concentration, application method, and safety precautions. For porous materials, use a dust formulation; for hard surfaces, a spray may be appropriate. Re‑treat after seven days to target newly hatched insects.
Consider non‑chemical alternatives such as steam treatment. A steam cleaner delivering temperatures above 100 °C (212 °F) penetrates fabrics and kills all life stages on contact. Move the nozzle slowly to ensure thorough coverage.
Seal any cracks in walls, baseboards, or furniture to eliminate hiding places. Install protective mattress encasements that fully enclose the mattress and box spring, preventing re‑infestation.
If the problem persists after two treatment cycles, engage a licensed pest‑control professional. Specialists can perform heat‑treatment of entire rooms, reaching temperatures that eradicate hidden populations without chemicals.
Maintain vigilance by regularly inspecting bedding and furniture, washing linens weekly, and keeping clutter to a minimum. Consistent monitoring and prompt action prevent recurrence.
