How to wash clothing infected with bedbugs? - briefly
Wash items in water at least 120 °F (49 °C) with detergent, then dry on the highest heat setting for a minimum of 30 minutes; seal garments in plastic bags before laundering to contain any insects. Use a separate load for infested clothing and clean washing‑machine components afterward.
How to wash clothing infected with bedbugs? - in detail
Cleaning garments infested with bedbugs requires a systematic approach to ensure complete eradication and prevent re‑infestation.
Begin by separating contaminated items from unaffected laundry. Place all pieces in sealed plastic bags to avoid spreading insects during transport to the washing area.
Pre‑treatment includes brushing visible bugs from fabric, then applying a spray containing 0.5 % permethrin or a similar insecticide approved for textiles. Allow the product to act for the manufacturer‑specified contact time, typically 10–15 minutes.
The washing cycle must meet the following parameters:
- Temperature ≥ 60 °C (140 °F) for at least 30 minutes; heat at this level kills all life stages of the pest.
- Full‑length wash with a heavy‑duty detergent; enzyme‑based formulas improve removal of organic residues that attract insects.
- Extra rinse to eliminate detergent and insecticide remnants.
After washing, transfer items directly to a dryer set to high heat (≥ 70 °C / 158 °F) for a minimum of 30 minutes. Heat exposure in the dryer is essential for any eggs that survived the wash.
For fabrics unable to tolerate high temperatures, consider the following alternatives:
- Cold‑water wash followed by a prolonged soak in a solution of 1 % sodium hypochlorite (diluted bleach) for 15 minutes, then rinse thoroughly.
- Professional dry‑cleaning services that use chemical solvents proven effective against bedbugs.
Post‑laundry handling:
- Store cleaned garments in sealed containers until the drying cycle is complete.
- Inspect items after drying; repeat washing if any live insects are observed.
- Clean washing machine drum with a hot water cycle and a disinfectant solution to remove residual pests.
Preventative measures include regular laundering of bedding at ≥ 60 °C, routine inspection of closets, and the use of mattress encasements that block migration. By adhering to these steps, clothing can be safely decontaminated, eliminating the risk of bedbug resurgence.
