How to get rid of lice on a bed? - briefly
Strip the bed and launder all bedding in water at least 130 °F (54 °C) followed by high‑heat drying. Vacuum the mattress, frame, and surrounding area, then apply a lice‑specific insecticide spray or powder approved for fabrics.
How to get rid of lice on a bed? - in detail
Lice infestations on sleeping surfaces require a systematic approach that combines physical removal, chemical treatment, and environmental control.
Begin with a thorough inspection. Use a fine‑toothed comb or a magnifying lens to locate nits and adult insects on the mattress, pillowcases, and surrounding fabric. Mark affected zones to prioritize treatment.
Remove all bedding, including sheets, pillowcases, blankets, and mattress protectors. Wash each item in hot water (minimum 130 °F/54 °C) for at least 30 minutes, then tumble dry on high heat for 20 minutes. Heat destroys both lice and their eggs; lower temperatures are ineffective.
For the mattress itself, follow these steps:
- Vacuum the entire surface, seams, and edges with a HEPA‑rated vacuum. Empty the canister into a sealed bag and discard it outdoors.
- Apply an approved insecticide spray labeled for lice, following label directions precisely. Cover the entire mattress, paying special attention to creases and folds. Allow the product to dry completely before proceeding.
- Place a steam cleaner on the highest setting (above 212 °F/100 °C) and pass it over the mattress for at least 10 seconds per area. Steam penetrates fabric and eliminates remaining eggs.
If chemical options are undesirable, substitute with a non‑toxic alternative: sprinkle diatomaceous earth (food grade) lightly over the mattress, leave for 24 hours, then vacuum thoroughly. The abrasive particles damage the insects’ exoskeletons, leading to dehydration.
After treatment, encase the mattress and pillows in zippered, lint‑tight covers rated for pest control. Keep the encasements sealed for at least two weeks to prevent re‑infestation.
Preventive measures include:
- Regularly washing bedding at high temperatures.
- Reducing clutter around the bed to limit hiding places.
- Inspecting new second‑hand furniture before introducing it into the bedroom.
- Maintaining low humidity, as lice thrive in moist environments.
Consistent application of these procedures eliminates current infestations and minimizes the risk of recurrence.
