How to get rid of bedbugs and lice? - briefly
Use high‑heat treatment (wash fabrics at ≥60 °C, dry on high heat, steam‑clean infested areas) and apply a proven insecticide labeled for both pests, then seal treated items in plastic bags for several weeks to prevent re‑infestation.
How to get rid of bedbugs and lice? - in detail
Eliminating bedbugs and lice requires a systematic approach that combines thorough inspection, targeted treatment, and preventive measures.
Begin with a complete inspection of sleeping areas, upholstered furniture, and personal items. Use a flashlight and a fine-toothed comb to locate live insects, eggs, and shed skins. Mark contaminated zones with tape to track progress.
Apply chemical or non‑chemical interventions according to the severity of the infestation:
- Heat treatment – raise room temperature to 50 °C (122 °F) for at least 30 minutes; heat destroys all life stages of both pests.
- Steam cleaning – direct steam at seams, crevices, and hair shafts; temperatures above 60 °C (140 °F) are lethal.
- Insecticidal sprays – select products labeled for bedbugs and lice, apply to cracks, baseboards, and fabric surfaces; follow manufacturer safety instructions.
- Silica‑based powders – dust into voids and mattress folds; particles abrade exoskeletons and dehydrate insects.
- Cold exposure – seal infested items in airtight bags and freeze at –18 °C (0 °F) for a minimum of 72 hours; cold kills all stages.
Simultaneously address personal hygiene:
- Wash bedding, clothing, and curtains in hot water (≥ 60 °C) and tumble‑dry on high heat for 30 minutes.
- Comb hair with a fine‑toothed lice comb every 2‑3 days, cleaning the comb in hot, soapy water after each pass.
- Isolate infested garments in sealed plastic bags for at least two weeks to prevent re‑infestation.
After treatment, implement preventive practices:
- Encase mattresses and pillows in zippered, pest‑proof covers.
- Reduce clutter to eliminate hiding places.
- Inspect second‑hand furniture before bringing it indoors.
- Maintain regular vacuuming of floors, edges of beds, and upholstered surfaces; discard vacuum bags promptly.
- Schedule periodic checks, especially after travel or contact with potentially infested environments.
Consistent application of these steps eliminates both bedbugs and lice and minimizes the risk of recurrence.
